应该是不成熟的技术霸王硬上弓的的结果
我是不打算碰OCZ家的存储了

为啥25nm的还不如34的?
解释如下：
When you compare the new and old Vertex 2 SSDs side by side, you can clearly
see the new unit has fewer NAND chips. OCZ used 16 32Gb (4GB) 32nm Hynix
NAND ICs on the older model but switched to 8 64Gb (8GB) 25nm Micron ICs on
the new revision. While still maintaining roughly the same capacity (not
including overprovisioning) this resulted in half the channels connected to
the controller resulting in slower write speeds under certain conditions.
The updated model will still retain 25nm flash (which was never a problem by
itself) but OCZ will use 32Gb ICs, filling all available channels like the
previous 32/34nm models as well as reducing RAISE requirements which will
get back some of the lost storage capacity and likely the performance as
well.
简单来说就是OCZ 在60GB上改用大容量芯片（*2）并通道数减半（/2），由此导致性能
降低。120GB及以上改用大容量芯片并不降低通道数所以不受影响。
问题不在25nm本身，而在通道减半这个实现上。 |

不过25nm还真是省一点电，呵呵
