The result of this lopsided performance improvements is a serious performance bottleneck, especially for … I would have really like to see single drive performance of SAS 15K drives vs SSDs .
To me, if the SSD drive manufacturers lose money, it’s their own fault for building crap that has higher write latencies than old fashioned drives with metal discs spinning at 7200RPM or slower. Not anandtech’s. …
