We decided to compare the RAIDDrive to Fusion-io’s ioDrive and the cheaper ioXtreme, as these can be considered direct competitors, rather than individual flash SSDs. For the sake of comparison, we also added Intel’s X25-M G2 drive.
Results: Access Time, Interface Bandwidth
The .14 to .18 ms access time is clearly longer than what we’ve seen on other flash drives, but still fast enough for most needs.
We measured almost 1 GB/s peak throughput, faster than any of the other solutions tested here.
