Hello all...

Recently had this card recommended to me by a friend and found what looks like a pretty good deal for a Patriot 16GB Class 10 card at Amazon:

Amazon.com: Patriot Signature 16 GB Class 10 MicroSDHC Flash Memory Card PSF16GMCSDHC10: Electronics

And if you spend $25 of more, the "Super Saver" shipping option is FREE!

There is also a 32GB card but I believe that card is $71...

NOTE: I, myself, ordered two of the cards but have not tried the card in my phone. Read and be educated with reviews or other information before you buy...CAVEAT EMPTOR!! Always going to be some people not happy or having problems with an item that works fine for others but just wanted to share this deal in case someone was considering a speedy card...

ocnbrze

if you guys, do not have this card, i highly recommend it. it is a class 10 card which is the main thing if especially if you plan on partitioning your card.

Mines coming in the mail tomorrow probably. Yay for free 2 day shipping.

It looks like most of the negative reviews on amazon are from people with the 32gb cards... Amazon lumps them all together in their reviews

L8AGIN

Almost as many 1 star reviews are 5 star. Hope it works out for you.

ocnbrze

been using this card for 6 months and not one issue yet. plus it is cheap. i bought mine from newegg when it was $35.

Rxpert83

As mentioned above, a lot of the bad reviews are from 32 GB. According to the manufacturer theres a known issue with the 32gb cards...

scudder

Well, now that you've said it, I'll give credit where credit is do..."my friend" was OCNBRZE who recommended the card to me. I just didn't want to throw him under the bus with the source of the recommendation in case people had problems so I posted it without proper credit.

So, now you guys can blame him!!

Ordered the 16 will report back. on that note can you just put the new card in and the rom will prepare and install what ever files are needed?
Or do you have to do a file transfer manualy

scudder

Was wondering how you got free TWO day shipping? I think I saw that with a free trial of "Amazon Prime" (whateverthehelll that is) but the free "Super Saver" shipping I got is what I typically get...arrival in like 8 business days or something long-ish like that.

scudder

Don't quote but I'm pretty sure that that IS what would happen...

However, if you have certain data that your old card that either (1) you want to keep and have access to (pictures, backups, etc.) or (2) data that your apps rely upon/need/use, then you're going to have to transfer the stuff you need to your new card. I believe, with the latter scenario, one just simply "copy and pastes" the data from the old card to the new card. If I remember correctly, I believe that is what I did when I upgraded from my stock 8GB card to my current larger 16GB card.

If someone can confirm what I wrote above, that would be much appreciated. ALSO, once the card is partitioned, does the card mount on a desktop as two separate volumes?? When one copies data from the old non-partitioned card to the new partitioned card, should the data be copied to a specific volume (if there is one) or just "drag and drop" on the card mounted to the computer??

Thanks!

ocnbrze

basically you will copy and paste your contents of your card onto the computer somewhere. then insert the new card. and you have two choices to do at this point:
1.you can just connect to the pc and paste back your contents of your previous card back onto the new card.

2.now is the best time to partition your card. you can do it at anytime, but since you have it and you do plan on doing it. why not now? just follow the ROOTING For Dummies Guide.....the Gingerbread Edition. there is a partitioning section.

as far as once it is partitioned, nothing will really change as far as accessing your card via the computer or on the phone. everything is the same. just follow the guide and you will be good to go.

has anybody ever used this website?
they've got the same card for $21.99

im also interested on this ADATA 16gb class 10 sd card.

Anybody with personal experience? some ppl are getting class 18 out of this card...

I'm fairly positive that "Amazon Prime" is some sort of Transformer, not anything to do with Amazon's site.

Amazon had a promotion sometime last year and gave a year of free amazon prime away to college students who signed up for it.

So naturally I'm using the free 2 day shipping for a year for everything possible. Its really nice....but not nice enough for me to pay for Prime after my year runs out.

i ended up buying the adata 16gb class 10 card from newegg. $28.99

I'll post this question here since you authored the above thread...feel free to move this question if necessary...

Under the "Partition Your Card" section, you recommend partitioning before flashing a ROM. First, since I'm already rooted having flashed the rooted 2.3.3 Gingerbread ROM, do I have any concerns here?

Secondly, going forward after partitioning, does your suggestion to wipe data (and sd ext) apply to stock ROMs as well or just custom ROMs?

Lastly, what does wiping sd ext. get rid of??

THANKS!!

ocnbrze

1.no concerns, but the stock rom does not have a2sd cooked in. and i'm not sure if darktremors will work or not on stock. i would try mikg2.5 i believe that it has a2sd support.
2.when flashing a rom you would do your normal wipe (data, dalvik cache and cache at the least) and you would also wipe sd ext.
3.basically what a2sd does is that it creates a symbolic link on your phone to the apps that are on the ext3 of the card. by wiping sd ext you erase that link and start over when your flash the rom and then restore your apps. some roms will not load right if the sym links are still there on the card.

scudder

Hiya...

So, got my Class 10 card in the mail today...in the process of doing some reading up on partitioning in preparation for using cm or darktremors apps2sd! Looked into your mikg2.5 suggestion and was a bit confused...does that ROM have the apps2sd already integrated and READY TO go with my partitioned card or is it merely "compatible" and I have to install the darktremor or other apps2sd functionality on my phone once the ROM is installed??

THANKS!!

Drew5150

mikg2.5 and all mikroms for the most part will have darktremor included with the rom. once your partitioned just install mikg and the install your apps from titanium and they will automatically get installed onto your sd card.

Ok, broke down and ordered the card.

jpkotor

wait... do the mikroms have cm a2sd or dt a2sd? i thought it was cm (the one that doesn't require me to know anything but restoring my apps to get them on the sd)... doesn't darktremor require some user input to do so? in another thread i read that mik3d has cm built in... i'm considering buying/partitioning a card and doing this app moving business but it has been confusing me. i am currently using mikg 2.51

dustwun77

With Mik3d, you just have to have the card partitioned per directions, use a fresh flash of the rom, and go to restoring your apps to the phone, it will do the rest.

I am not sure exactly what it did, as far as how much was moved or symbolic links and that stuff, but it put the apps on the card by itself.

I have tb pro, when you look at the overview screen, it shows you have an sd partition and stuff in it.

jericko

I just ordered as well, I currently have a 16gig class 2 that is slow as dirt. Looking forward to trying partition and try A2SD!

Drew5150

its been a looong time since I used a cm rom. and I have actually never heard of cm a2sd. and back when I did run a cm rom I thought it used darktremor, but they may have their own version.

darktremor doesn't have any command you need to make it run. but lets say your already on mikg 2.5 and you buy an sd card. partition it in recovery, then boot into the rom. you can then open a terminal and run a command to move your apps over. any newly installed apps will automatically get moved over.

the easiest way is to just flash a new rom ( or reflash the same) and then install your apps from titanium and they will automatically get moved over.

I bet the cm version of this works about the same.


one very important thing is to NOT use the native move apps to sd that comes with the phone, or any app from the market.

jpkotor

so after i run the terminal command once the apps i install AFTER that will automatically install to my SD card? as in the command changes the way the phone installs apps rather than just move the currently installed apps?

automatically? so do you mean reflash the rom, run darktremors via console emulator, then restore my apps via tb? in which case if the first part is correct they will automatically go to sd card (as will newly installed apps, again assuming i understood you correctly above)?

scudder

Yeah...I'm not clear on this also...not sure if it is "working" for me.

I partitioned and wiped and flashed (with patches up to) Mik2.5. Set up the phone with a reinstall of Titanium Pro and was ready to reinstall my apps. I launched Titanium and I can see the tally of available space including my partition. Here's all the available space info I personally started with:

System ROM: 367 MB (32.8 MB free)
Internal: 448 MB (382 MB free)
SD Card: 13.9 GB (3.50 MB free)
SD card (a2sd): 1.91 GB (1.76 GB free)

So look like I'm ALL SET and ready to go!!! But....

I installed only a FEW apps from my Titanium backups (Chomp SMS, ROM Manager and Root Explorer) but I'm not sure they went to the a2sd partition. My "Internal" free space went from 382 MB to 373 and the the a2sd free space stayed at 1.76 GB.

Now TWO things...I'm NOT sure if my dalvik cache is on the partition so as the dalvik is build THAT might be the reason my internal has dropped from 382 MB free to 373 MB. I read but don't recall how to move the dalvik cache to the partition...does anyone know if this is ALREADY set up on my phone this way or, if not, if it is SUGGESTED to move the dalvik cache to the partition??

SECONDLY, I know that my 1.76 GB partition is 1,760 MB so I would need 10+ MB of app installation on the partition to see my free space number change from 1.76 GB to 1.75 GB but how does one check the location of apps to make sure they are installed on the partition??

THANKS!

---------
EDIT: As I usually do, I'm leaving the above information to help someone with a similar issue...

After posting the above I used a filter function in Titanium to look at "all" my apps that are installed on the "external." What came up was my Chomp SMS and ROM Manager...the two apps that installed. SO, it appears that, without doing ANYTHING special, the apps are restored to the EXTERNAL partition!

I'm still wondering about my dalvik cache location question above though....

i am thinking that most apps aren't really that big. so with that 2 GIG a2sd partition that tb is showing you, it will take a good bit to actually get it to move, It must just round off or something.

I remembered DaRayvn talking about big games, so i went to market and got Angry Birds. It is 18 meg! When I got it installed and then looked at the tb a2sd partition, I saw it move it then.

I think it is working. what is confusing me is when i go to manage apps on phone, it looks like the apps I expected to me moved are still telling me I can move them to sd card what I think is the partial, apps2sd way. If they are already on the partition, is that 'symbolic link' fooling the phone into telling me it is still there to move?

With Mik 2.52 loaded with chopsuey kernel, and whatever apps I have, tb is telling me I have 446 MB internal, with 359MB free, and a2sd, 1.91 GB with 1.71 free.

scudder

We're on the same page...I'm in the process of batch restoring about 50 "important" apps with the Mik ROM I flashed this morning so I'll let you know how my free space is affected and where.

With regard to your comment about your phone "still telling you that you can move apps to the SD card" I don't recall where I saw (with all the partitioning and apps2sd-ing and flashing threads I've viewed recently) but it is very important that one does NOT use the old "froyo" app2sd options still seen on the phone. I guess one could move apps to the internal memory if that is desired but I do NOT know how to move them back to the partition. It's probably with a terminal command but definitely not through the "Move to SD" option in the Application Manager.

scudder

I just batch reinstalled 43 apps. Below is my "before" and "after" memory tallies:

Before:

System ROM: 367 MB (32.8 MB free)
Internal: 448 MB (382 MB free)
SD Card: 13.9 GB (3.50 GB free)
SD card (a2sd): 1.91 GB (1.76 GB free)

After:

System ROM: 367 MB (32.3 MB free)
Internal: 448 MB (317 MB free)
SD Card: 13.9 GB (3.44 GB free)
SD card (a2sd): 1.91 GB (1.74 GB free)

So, my a2sd partition finally went down about 20 MB (sounds about right for the 43 apps I installed). I'm not sure why my Internal and SD Card went down....sizable jump (65 MB) for the Internal and 20 MB for the SD Card. I think the Internal change has to do with cache/dalvik cache building up but I'm NOT sure why my SD card has changed...

jpkotor

just caved and bought the card. i will be fooling around partitioning my 8gb class 2 stock sd card for the next couple days until the new one arrives

Drew5150

yeah sorry I wasn't around earlier guys. there were a few questions and I don't feel like quoting everyone.

1: there is no need to run any terminal command to get darktremor running. there is also no need to do any special install for it either as it comes with the rom.

2: darktremor works in the background and you will never see it work really. the program basically determines (not sure how) if and where apps should get installed (sd card or phone) but then tricks your system into thinking they are all installed on your phone.

3: under manage applications you should not see any apps on your sd card. and do NOT move any there.

4: cache... this is a good question as I think mik has moved the cache on different builds and I'm not sure where it is on mikg. what I do know is that I have run the command to remove cache and other times I forget. but I have never really been able to tell difference to be honest. I would recommend running the aps2sd command for no cache though. I'll come back and edit this post with some commands or links.

5: not all apps can be installed on the sd card even with darktremor so you will see your internal and sd ext space go down. yeah with that huge ext it will take a few apps for it to go down XD

edit: a few commands

open terminal

su
a2sd reinstall
a2sd remove

reinstall installs apps to the sd card and remove puts them back on the phone. if you came from a fresh install there is really no need to run these commands.

su
a2sd nocache

nocache moves cache to the internal storage. but as i read the guide it looks like this is unnecessary with an odexed rom like mikg. here is a quote from the guide.

"*NOTE: Any app that is odexed does not create dalvik cache. This means that on an odexed ROM, your dalvik cache will be significantly smaller than on a deodexed ROM. Therefore, moving your dalvik cache is probably no longer necessary."

dustwun77

Ha, can I thank you twice? Appreciate it much!

Drew5150

Ha, your welcome

mikem0269

What does system rom mean and why is the free part so low? How does that affect the phone? Im guessing that is where the rom is located on the internal storage. but the free portion just seems realy low.

dustwun77

I think you are right. with an aosp rom, it has lots more left.

I guess the main thing is that it fits,

Drew5150

the rom is your internal memory, this is where your OS (operating system) will get installed. in the cell phone world the OS is called a rom and that is kind of confusing.


yeah and if you guys are using mikg or any other sense 2.1/3.0 rom the internal free space is a lot less then say a froyo rom. the new sense adds a lot of stuff.

No need to apologize for your response delay...THANKS for replying with all the questions that have been floating around!

Question about Mik determining where (and if they can) put certain apps on the SD card or internal.

I have had some inexplicable "sd card" problems in the past (pre root and rooted with Gingerbread but all pre-Mik ROM (I just flashed Mik for the first time literally a day ago) where my card could not be read and, as a result, NONE of the apps installed on my card could be launched or used. After that experience, I kept a few CHOICE and IMPORTANT apps for accessing important information or functions of the phone on the INTERNAL memory of my phone just in case this sd card issue reared its head again. I did so even though some of these apps were capable of residing on the card even without the need to "force-move" any apps that the dev didn't permit.

So, with the above sd card issue that I've had in the past in the back of my mind, is there any way to choose...and to do so SAFELY with regarding to how Mik's ROMs determine placement of apps...SPECIFIC apps to reside on the internal memory of the phone??

ocnbrze

no i believe that it is all or nothing. there is a command that you can use to move all free and paid apps back to the inrenal memory. there is no command that i'm aware of that will move just a single app to and from the sd card. here is a list of commands that you can use:Darktremor Apps2SD Command Line Help | Facebook

Hi All...

So, based upon my own recommendation I purchased the Patriot Class 10 card, partitioned, installed and flashed Mik 2.52 on my phone. I have an app called "SD Card Speed Test 1.2" that does a read/write test on your card so I decided to run it. Here are the results:



Read speed is decent at 14 MB/s but write speed is BLEH at 5 MB/s yielding a CLASS 4 result overall So I decided to run the test again:



...even WORSE with 13/3 read/write speed yielding a CLASS 2 result!!

So, what's to make of these results?? Is this app fair/accurate test of read/write speed?? Is this an issue for other people? Specific to my phone and isolated??

Also, am I confused...is the "Class 10" designation of these card supposed to be an OVERALL score (of which I received, overall, Class 4 and Class 2) or is it JUST for the READ speed. My read speeds are decent and I think that is what is important with reading data off the card as fast as possible for the phone to function smoothly and quickly...but should my write speed be THIS slow??

ocnbrze

i never really trust any of those apps. same goes with quandrant scores. i never trust the results. i only go by performance. if your card is performing correctly then your apps should be running smooth. that is all that really matters. trying to wrap your brain over this is not worth it, in my opinion. just go with how your phone is working.not sure on what my speeds would read, but my apps work perfectly fine on my card. i play plant vs zombies all the time and no issues lag. it performs quite nicely.

scudder

Good point...I'll have to try out a processor/card-speed intensive app and see how it holds up. That's more of a real-life test than the "score" I got with the speed test.

I read somewhere...perhaps in the Mik thread...the question posted about that card speed enhancement script...??...forgot what it was called but I ran it on my Gingerbread ROM with my old slow-ass card and saw some improvement. Would running that script (do you know what I'm talking about) NOT be recommended with my Class 10 card AND my Mik2.52 ROM?? I'm asking because I can see, taking the card into consideration, that the script just wouldn't yield a benefit and can see, considering the Mik ROM, that that ROM has been optimized in such a way that screwing around might do more HARM than good...??

ocnbrze

the only one i know of is from here:
[Script][CWM] Increase Read Cache for better SD Card access - xda-developers

and reading the thread i found this app:
https://market.android.com/details?id=com.sdincrease.it

not sure on running it or not. make a nandroid backup and give them a go.

dustwun77

I guess I'll put this here.

I got my class 10 card today, it is purty! fast as greased lightning, too.

I saw I was never using the whole 2 gig partition with my other card for my puny amount of apps so I just went with 1 gig on this one.

Well, not sure what was the issue, maybe operator error some other way, but, nands with 2 gig partitions don't restore to cards with 1 gig partitions. Predictable, but worth a shot. lol

No biggie. titanium backup is too cool! just copied it over with some roms and nans and patches and scripts and here we go.

Mik2.53 is a real timesaver, not having to patch, patch, patch and worked well with a2sd.

Got to get this badboy set up enough then i am going to call it a day, you all keep it on the road out there.

DaRayvn

you have a purty sd card?? LOL...hey man...im happy for ya lol...glad it all worked out ok...

If it hasn't been mentioned, download a2sdgui from market (all of u with a2sd questions) it made things worlds easier for me.

scudder

Yep...involves changing the value of the file located at /sys/devices/virtual/bdi/179:0/read_ahead_kb

Since your post, I found the original write-up I saw back in February in a goodandevo.net article that provides a nice explanation and screenshots:

How to increase SD card read speed on rooted HTC EVO 4G

Another article here with information and links:

Is Your EVO a Slow Reader? SD Card Read Speed Fix | xda-developers

It appears that unless you use the flashable zip, the value change for the "read ahead" file will AUTOMATICALLY RESET with every reboot.

HOWEVER, our androidforum's very own AKAZABAM created a flashable zip to avoid the reboot reset!!:

Speed Up SDCard Read Access

Would be a good idea for anyone interested to read the above articles and the links included with them. The flashable zip requires a ROM that is NOT stock and that utilizes "init.d" found at /system/etc/init.d/ folder so not only will results vary, results might need to be adjusted after every reboot.

And the link to the app you provided may do the same thing that the flashable zip does.

Anyway, links above for anyone to read. I, myself, am unsure about the values to put in. I just checked the read ahead file in my ROM and it has a value of "4096" so not sure if tweaking this value would have a benefit for me. I might nandroid and try it out...

scudder

Hey, it wasn't that bad...it was only patch, patch, not patch, patch, patch!

scudder

I just downloaded the app to take a look. I should WARN people to read the "About/Help" tap on the top of the app window when launched BEFORE TRYING ANYTHING so that you understand what this app can do. I kinda sorta hit a button thinking I would get info and, instead, started a PROCESS which, fortunately, was "not available for my device" Got LUCKY because I could have triggered something I did NOT want to happen!!

Other than that warning, good info...thanks...
