Transfer Rate Range (SSD)
This chart shows you 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 solid state drives (from minimum and maximum).
The 20 nm IMFT 60074157 NAND flash memory chips proved to be very fast, delivering a high throughput of 391-394 MB/s. That puts the Western Digital Black²'s SSD component in between the 240 GB Intel 520 Series SSD and the 256 GB OCZ Vector SSD.
Transfer Rate Range (SSD)
This chart shows you the range of platter-to-buffer transfer rates from the innermost track to the outermost track for hard disk drives. In other words, it shows you the range of transfer rates of hard disk drives (from minimum and maximum).
Although the HDD component (the WD10SPCX) uses just 2 platters instead of 3 platters with the older WD10JPVT, it did not deliver a massive boost in throughput. We would have expected at least a 30% boost in raw throughput from the 50% increase in areal density but the WD10SPCX was only about 3% faster than the WD10JPVT. This is most likely due to the "Advanced Format effect".
Business Disk WinBench 99 (SSD)
Even though the Western Digital Black²'s SSD was capable of very high throughput, it was only average in this test.

Business Disk WinBench 99 (HDD)
As expected, the Western Digital Black²'s HDD was slightly faster than the WD Scorpio Blue Slim (WD5000LPVT). The only difference between the 500 GB WD Blue Slim and the 1 TB WD Blue Slim drive used in the Western Digital Black² dual drive is the additional 500 GB platter and a larger 16 MB SDRAM cache.

The WD Black²'s SSD didn't do very well in this test, coming in just behind the rather dated OCZ Vertex 2 (E) SSD.

High-End Disk WinBench 99 (HDD)
The WD Black²'s HDD also didn't do well in this test, coming in significantly slower than the WD Scorpio Blue Slim (WD5000LPVT). It's possible that it may be incurring some performance penalty from the SATA bridge.
