I/O Benchmark Results
Only 40 I/O operations per seconds for a single drive or 40-50 I/Os per second for the RAID 0 setup is almost half the I/O performance of a traditional hard drive with the IOmeter database benchmark. Although a database benefits from a SSD's quick read speed performance, it can get bottlenecked if multiple write requests come in at the same time. As command queues increase, the single hard drive does not even scale up, as this flash-based HDD does not support command queuing.
The performance of flash HDD in a RAID 0 array can keep up with conventional 2.5" drives under normal file server workloads (with reads and writes for varying file sizes). However, a single flash HDD cannot match the performance that a traditional HDD offers.
