此外传统硬盘都是大厂在做,都是经过各种测试再到消费者手中,但是ssd就不同了,芯片的指标就和lcd屏幕一样abc都有不同价格,硬盘来次突然死亡法不是一般人能接受的,可以看看下面intel的解释:D
Q. Are there different "grades" of flash memory? Why are USB sticks so much cheaper at the same capacity?
A. Yes, there are many different qualities of flash memory components, each with a different cost. The process is similar to speed binning for CPUs. Removable media products like USB memory sticks typically use the lowest quality flash they can get away with, and if you tried to use one as a hard drive I think you would notice the difference immediately. The difference is not only speed, but also reliability. Higher quality flash chips will encounter fewer errors over its life span, which translates into a significantly reduced chance to lose data on an SSD. It is certainly possible to build cheap SSDs out of bargain flash memory, but be careful. If something looks too cheap to be true, it probably is.
