________________________________
IF you want to use a sdcard to boot a android on it(just in case), do not
buy this or wintec or any of those cheap brands.
I suppose for storage purposes they are OK, but a class 10 Wintec or class 6
A-Data will not boot a Honeycomb v4 image for nook color.(I learned the
hard way) I have tried about 4~5 sdcards, and meanwhile I can not say Wintec
or A-Data is worse than Sandisk or Kingston(the benchmarks will show that
those Wintec class10 cards are indeed class 10), somehow using cheap branded
sdcards will cause inability to boot, or inability to i/o from the boot
partition based on my experience. On the other hand, according to the XDA
forums, this problem is known usually to happen to those "cheap" branded
sdcards.
Also I might add, although I can not prove it, it seems that Honeycomb runs
smoother on a Sandisk Class 4 than on a Class 10 Wintec or Class 6 A-data.
Again, I will add that according to "scientific" benchmarking data, Wintec
or A-data are quite good, but on real-world usage, they somehow magically
suck .
== Edit. SD cards I have used to tried to boot honeycomb. (Well of course
not everybody is going to do this, so read the information accordingly)
Wintec C10 16Gb, v3 fail, v4 fail. (FYI, about $28 at frys.)
A-Data C6 8Gb, v3 success, v4 fail.
Sandisk C4 8Gb, v3, v4 success.
Sandisk C2 4Gb, v3, v4 success, but after multiple reboots.
Patriot C10 8Gb, v3, v4 success.
== After all of this, I have settled using the Sandisk C4 one.

s********i 发帖数: 17328 | 5 你要求什么?如果只是root一下,是一次性的,什么class都行。如果你想在SD上run,
当然是class越高越好,但是小文件随机存取,速度都差不多。大文件才有区别。 |

我09年BF同样价格-10%bcb买的 |
a******g 发帖数: 53 | 7 你就照这个post在amazon买sandisk class4好了,
便宜的sd卡用的主控和闪存芯片不好,随机读写性能很差的,class几也是白搭
不推荐newegg,要是不好用退都退不掉

Wintec

p******s 发帖数: 2552 | 10 这个class其实很不靠谱 class 4的卡写入达到6-7M/s很容易
sandisk早期class 6的卡写入能到>10M/s以上

g*s 发帖数: 116 | 11 现在honeycomb也可以安装到NC自带的内存了。跟在sd卡上安装比较的话,这两个选择
有什么优缺点?
用自带内存更快,但是不方便恢复BN的系统? |
s****c 发帖数: 11300 | 12
那个class还要求有小文件和随机文件读写速度要求的
所以连续读写速度上去了 不一定class能上去
