Comparing SSD's

Not really. Most storage vendors play number games when representing the capacity of their drives, so it's not unusual to see a different capacity than you expected. Most of the time this is due to the difference between the base-2 notations that computers use and the base-10 notation that most humans use. Numbers like 128 that are squares of 2 suggest that you're getting a number in gibibytes instead of gigabytes, which can be misleading. As long as the true capacity is more than enough for your needs, you're good.

120-128 GB (or GiB) looks a little small for something like Windows 7 to me. Technically it can be done, but free space will be tight. Don't forget about the hidden partition. The hidden partition on my laptop is only 100GB, which is smaller than the one that came pre-installed. My C: drive is nearly 200 GiB, which is the smallest that I could shrink it to on my 750GB HD. Microsoft says it'll install, but you may be giving up something that isn't readily apparent. I'd wait until I could buy a SSD twice the capacity, more like 250GB, if I had my druthers.

Linux OTOH will be more than happy with 120GB (or less) of disk.

I think you meant your hidden partition is 100 MB not GB.

Thanks for the reply, didn't realise that posting in here meant you had to move threads just to help me out.

250GB SSD's are definitely out of my price window. So is it worth waiting for the prices to go down, or just get a 120GB?

Obviously you said to wait, but would the free space on a 120GB be that tight? I don't even know how big Win7 is tbh...

I successfully ran Window 7 off of a 60 GB SSD - the trick is to move all non-essential folders off the SSD - stuff like My Documents, My Pictures, etc.

With my setup, I have my new 180 GB SSD (Intel Cherryville 520 SATA III) as my OS drive, my older 80 GB (Intel X25-M G2 SATA 2) set up for all of my profiles, and dual 1 TB (Seagate Barracuda 7200.12) drives for storage.

Even before my incorporation of SSDs, I always kept data separate from my OS drive, so in Windows 7 I would always move the 'special' folders from the default location to another mechanical drive.

When I got the 80 GB SSD a few years back, I revamped the installation. I used Profile Relocator to relocate the entire user tree over to one of the mechanical drives, to save space on the 80 GB.

When I bought the 180 GB drive a couple of months ago, I revamped it again. I installed Win7, used ProfileRelocator to move the user tree to the old 80 GB drive, and set up the page file on both SSDs only. I then again manually moved the special folders to the mechanical drives to have ready access to all of my documents, photos, videos, etc.

Now, all of the cache related stuff is on the 80 GB drive, the main OS files and all programs on the 180, and all data on either of the 1 TB drives.

(I've actually toyed with combining the 2 TB drives into a RAID, since I really don't want to lose my data, and neither drive is more than 25% full, but have not found the time to incorporate the idea yet).


My /windows directory alone is 22 GB, pagefile is 12GB, hiberfil.sys is 10GB.

So that's ~44GB right there and doesn't include some other basic stuff.

Granted your page and hiberfile/pagefile may be much smaller depending on your RAM. But I think assuming ~40-50GB for Windows is an ok approximation.

120GB is do-able, IMO, just tight.

That's about right. I have 12 GB of RAM, but I made my pagefile 12 GB on both SSDs, just to stagger it a bit.

I think I might do it. I mean, how long till 250GB SSD's are less than

I can get the 250GB, but it just means that my 'late Christmas present budget' will be used up. Otherwise I was gonna get a £60 ssd and a kindle or a Nexus 7.

If £125 for 250GB is a good deal, I might consider just getting it now. :-D

But what you're saying is that 120GB can be done...

Oh yeah, it can be done - albeit a little creatively.

Check prices on a 180 - larger than a 120 (so you'll have room for a couple of large games) and still within your budget. :sly:

Some apps use pagefile even if it is not needed, and this can cause the app to lag (compared to other apps that will only use the pagefile when actually needed).
When I had a singe SSD I did that as well, but with dual SSDs I now stagger the pagefile across the SSDs only.
.

That's exactly why I have a small pagefile on my HDD. I try to force programs to use RAM only, while leaving room to throw a RAM dump if I ever get a BSOD. With my 16GB of DDR3, 1600mhz, I want to get the most out of it. :D.

Not to mention a 16gb pagefile is just waste IMO.

Hmmm... Windows might have been changed since I got deep into its depths, but back in the day trying to force Windows to do pretty much anything was just asking for trouble (like thrashing). The best (and only) way to keep the application's executable image in RAM is to supply more than enough RAM. Even then that's no guarantee.

Like I said, my knowledge is dated. The last time Microsoft published really in-depth info about Windows internals was pre-Vista. Up to that point the Windows virtual memory subsystem used the executable file itself on the HD for paging purposes. So shrinking the pagefile wouldn't accomplish the desired effect, and could make things worse by creating race conditions as the VMM subsystem tries in vain to write to cache.

The Windows 7 / Server 2008 R2 documentation is adamant about allowing Windows to manage the pagefile(s), and suggests that using fixed size page files is a bad idea. To me that means that the trick of preallocating a fixed-size pagefile no longer helps performance, and may even hurt performance.

True, a 16 GiB pagefile isn't likely to be used fully, but the pagefile has to be at least enough to hold the commit charge and a little more. This old MCSE lets Windows 7 manage the paging file and uses his 32GB SSD with ReadyBoost to cache the terabyte HDs.

True enough, you can let Windows manage it, but you can also enable it on multiple drives, which allows for (theoretically speaking) better management of the page file.

Since I no have dual SSDs, I enabled it on both, letting Windows take care of the size.

There's this OCZ Octane 256GB for £120
OCZ Technology 256GB Octane SSD SATA 3 Solid State Drive - OCT1-25SAT3-256G - Scan.co.uk

But more importantly

This OCZ vertex 240GB for £90

OCZ 240GB Vertex Plus SSD - 2.5" SATA-II - Read.. | Ebuyer.com

Edit: The vertex is actually Sata II , so 250MBs..... DUnno if it's still worth it

Also found a Sandisk
SanDisk 256GB Pulse SATA-III SSD | Ebuyer.com


But the other,more expensive SSD's seem to have much higher read/write speeds....

Lol, I like how before I said a 250GB was too expensive, and now I might get one :-D

Just a FYI, I have a 1TB HDD and 8GB ram.

But if I'm gonna pay the money, might as well get SATA3, right?

How much of an actual difference would SATA3 make over SATA2...?

And is OCZ a good enough brand to trust, and should I get a particular model?

More succinctly, SATA II drives averaged around 250 MB/s. Theoretical max was 300, IIRC.

SATA III drives break 550 MB/s easily, and can be boosted even faster - in a RAID setup, for example, people are getting over 1.0 GB/s speeds.

So, yeah, SATA III is the way to go if you can afford it.

Alright then. I'll be on the lookout for some deals.

Is a 250GB OCZ for £125 a good deal?

I think the page file stuff looks quite complicated so I think I'll get the bigger drive. :S

Is this SanDisk 250GB for £115 good?
http://www.amazon.co.uk/gp/aw/d/B00...50936&smid=A3P5ROKL5A1OLE&tag=googlecouk06-21

Also, how much less should a 180Gb drive cost? Realised that hey might not be that similar in price to 250's, espeically when I'm now looking at

Think I'm gonna stay focused on Samsung 530 (think that is the right model number)
And the Intel 330 or the 5-whatever...

Can't remember the specific models I was looking at now and no pc for easy look up.

All I know for sure is my budget won't let me go over 200 and I want something bigger than 200gigs. And I agree, I'd rather just go with sata III get the most bang.

Eventually want to raid but will be happy with one at first

In addition to the other links I put up, I still don'tknow if I should opt for a 120Gb, or a 250GB SSD.

I know that the 120 is cheaper, and I could squeeze a few big programs onto it and I can be happy-ish.

But I also know that I will try put as many games as possible onto it, and now most modern games are several GB big, so I don't know if a 250GB is more 'sensible', albeit more pricey.

I would ask about 180Gb drives, but only the Intel 330 one's fall into my budget, and they're the same prices as a 250Gb from other OEM's.

I guess I'm gonna have to go for a 250GB, not sure which yet...

Means I won't be able to afford my Nexus anymore :(

Get the 250GB. I've only put 3 games a few programs on mine and I've used over 120GB.... which is why I'm happy I went 250GB.

It may have been mentioned before, but I read that the 4K write speeds are the ones needed to be highest.... Used 50% of the time...

I'll have to compare all the 250GB drives, but do I need to worry about warranties and stuff?

I'm going to have trouble cos there's a Sandisk at £115 and then a variety of ocz, Intel, Samsung.. Up to £150. Which is when you think of it is only £35 more.... 35 quid more ssd? I dunno.

Are SanDisk ok to get or should I push for a certain model ?

Edit : idea : Two 120gb is cheaper than one 250. See where I'm going? Can I do that?

Problem : only 2x SATA3 ports on my mobo, unless those pcie connectors are any good / SATA2 is ok for my hdd.

Another question : would you buy off amazon from a seller with 800 ratings. 98% positive - just to save £10

Hard to say, but SSDs are constantly going down. Just this past year they finally dropped below the $1/GB here in the US.


Edit: Also to add to what John Galt said, SATA 3 is definitely the way to go. Luckily SATA2 is almost harder to find than SATA3, and you dont really pay anything extra for it.

Newegg lists the following # of models for sale:
SATA (2)
SATA II (103)
SATA III (262)

Sure, you want to take advantage of your SSDs for paging. Here's a good guide that gives what's IMO excellent advice.

Sorry, they're both 250GB (SanDisk is 240)

Samsung is from Amazon, Sandisk on dabs.Com

Sandisk 240GB Extreme SATA 6Gb/s 2.5" Solid State Drive (SDSSDX-240G-G25) - dabs.com

Or I could wait it out. Til easter.


Edit : apparently the 830 Samsung is better than the 840, so that draws that one out.

Found this Mushkin, but it's from the US.
240GB MUSHKIN CHRONOS SSD (HARDDRIVES), Computer Hardware on sale at CQout Online Auctions


The 830 isn't better than the 840, rather the 840 has more models. (e.g. 840 vs 840 Pro)

The one you linked is a lower-end TLC NAND drive. Whereas the more expensive high-end Samsung 840 Pro is MLC.


See anand (as always) for several excellent articles about TLC/MLC and that drive
