WinBench 99 Version 2.0

Business Disk WinBench 99

The 256 GB Western Digital SiliconEdge Blue was the second-slowest SSD in this test, coming in just behind the 160 GB Intel X25-M G2. However, it was 9% faster than 64 GB Kingston SSDNow V+ (Gen 2) and more than 2.2x faster than the fastest hard disk drive in this comparison, the 10,000 RPM 600 GB Western Digital VelociRaptor.

High-End Disk WinBench 99

In the High-End Disk WinMark 99 test, WD SiliconEdge Blue SSD slipped to last place, just 1% behind the 128 GB Super Talent UltraDrive GX, and 9% behind the 64 GB Kingston SSDNow V+ (Gen 2). Even so, it was 54% faster than the 600 GB Western Digital VelociRaptor.

Transfer Rate Range

This chart shows you the range of platter-to-buffer transfer rates from the innermost track to the outermost track for hard disk drives, and the range of memory cell to controller transfer rates for solid state drives. In other words, it shows you the range of transfer rates of hard disk drives and solid state drives (from minimum and maximum).

Unlike hard disk drives which deliver a wide range of transfer rates, solid state drives have an almost uniform transfer rate across the entire device. With a flat transfer rate of 248 MB/s, the Western Digital SiliconEdge Blue SSD wasn't the fastest SSD as far as the internal transfer rate was concerned. However, that transfer rate rate was 62% better than the best possible maximum transfer rate of a 10,000 RPM hard disk drive, namely the 600 GB Western Digital VelociRaptor.
