没必要把evds太神化了，买新不买旧
eurs没半点问题，速度、功耗更好，也没有"c1"。
2t的evds我现在有6块，2t的eurs有三块，现在对比下来eurs绝对比evds好用。
居然还抢着去买面临停产断货的产品，，之前evds也不就是不稳不火中规中矩的么，怎么突然就成了宝贝
要说4k盘，可以说以后民用盘都是4k，由不得你，更何况在win7/2008r2下丝毫无半点问题(不过ears没用过不清楚)，并且据老外说的，4k盘将ecc块整合后得到的大ecc块其实对数据保存更有利
The same amount of physical space now requires fewer ECC blocks, fewer lead-ins, and fewer gaps allowing for more continual data space and a larger ECC code word increasing data integrity.
Why 4k and why now? Why?
Rising bit density means smaller magnetic areas and more noise. The underlying or raw disk media error rate is approaching 1 error in every thousand bits on average – while tiny media defects can lose hundreds of bytes in a row. The larger sectors enable more powerful ECC to fix those gaps.
Why now?
A 512 byte sector can’t support enough ECC to correct for higher raw error rates. Thus bigger sectors with stronger ECC capable of detecting and correcting much larger errors – up to 400 bytes on a 4k sector.
The 4k sector enables disk manufacturers to keep cramming more bits on a disk. Without them the annual 40% capacity increases we’ve come to expect would stop.
Note: the longer ECC doesn’t change the drive level unrecoverable read error rate. It remains at 1 in every 1014 bytes.
4k sectors have been cooking for over a decade. The late adopters are the cloning software vendors. More on that in a moment.
