A very important part of overall system responsiveness is down to hard drive performance. We use two of our favourite benchmark utilities Crystalmark X64 Edition and HD Tach to rate performance from the onboard SATA controller.
The pair of SSDs' sequential read speed of over 720MB/s is tremendous. SanDisk's U100 SSDs show admirable read performance when used in RAID 0 configuration.
Write speeds aren't anywhere near as impressive, with the sequential result registering as a much lower 367.6MB/s. We would expect much more from 2 SSDs in RAID 0 mode, but evidently SanDisk is selling its drives on the basis of excellent read speeds.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.
Consistent and competitive read and write speeds are shown by the Western Digital Scorpio Black HDD. It justifies its place as one of the premier 2.5″ hard disk drives.
