Availability of 32GB MicroSD cards

Exactly, the ones I quoted are name brand class 2, or no-name brand class 4 16gb microSDs. Not even talking about class 6 yet which is where you want to be when Google releases an Apps2SD native support.

Two noob-y questions sorry.

1) With class 6 being ideal, would a class 4 cut it for future SD-stored apps, or not really?

2) The N1 supports micro-SDHC right? The specs sheet mentions micro-SD card support, but if it takes up to 32gb, it's implicit that it's micro-SDHC?

i just ordered a sandisk 16GB microSD off ebay (free shipping) for 39.99.... i'm assuming since 32GB (and 64GB) *just* coming out... they will be more than double/quadruple respectively compared to 16GB... which seems to be the sweet spot for price/GB right now...

so wait... the Sandisk 16GB I just bought is "class 2".... from what @sooper_droid12 said above... is that bad? did i just waste $40?

I guess worst case, it will become my porn movie SD card... ;)


seriously though - this is the limitation of lower on board memory... at some point, putting apps on the SD card will be necessary, but at that point... the SD card will be become somewhat semi-permanent if you want access to those apps... say you have 2 or 3 SD cards that you want to swap with say different song libraries or movie libraries, etc... you'd have to copy all the SD stored apps to each SD card to maintain full app functionality when swapping SD cards....

So I don't have to post it up later. Here are the WRITE speeds for class 2, 4 and 6:

Class 2 = 2 megabytes/second
Class 4 = 4 megabytes/second
Class 6 = 6 megabytes/second

The READ speeds are different and based off of CD-ROM speeds, so you'll see numbers like 16x or 32x. So, here they are:

Rating Speed (MB/s)
6x 0.9
32x 4.8
40x 6.0
66x 10.0
100x 15.0
133x 20.0
150x 22.5
200x 30.0

Class 2: 2 MByte/s - 13x
Class 4: 4 MByte/s - 26x
Class 6: 6 MByte/s - 40x

But these read speeds may vary from card maker to card maker and usually represent the "minimum" speed. Some will advertise up to 100x or more. So, do your research. Will it be enough for App2SD? I think so far, with the apps currently available on the Market, people with rooted DROIDs are doing okay with their OEM class 2 microSD.

I just bought a Sandisk Micro-SD which was meant to be a class 6, but has a 2 on it, the supplier told me:

The Sandisk Ultra Micro-SD is the fastest micro-sd card in the world. Sandisk recently revised the packaging to show a 2 but the memory card itself has not been changed at all.

It has a read speed of 15mbp/s and a write speed of 9mbp/s. All Class 6 micro-sd cards from other brands only have read/write speeds of 6mbp/s.
I did get about 8mbp/s write speed when I tried it, so it sounded plausible.
