WD's Caviar Black series SATA II hard drives feature a faster spindle speed
and 32MB of onboard cache. Drive capacities range from 500GB through to 1.0TB, but all the Caviar Black series drives use Perpendicular Magnetic Recording. 86% Rating:
Sandra is designed to test the theoretical power of
a complete system as well as the individual components. The results are also
purely theoretical and may not represent real world performance.

Random access read tests don't see significant
improvement when two Western Digital Caviar Black
WD1001FALS hard drives are configured in RAID 0, though Sandra's Drive Index
jumps from 85 to 170 points.
HD Tach is a physical performance hard drive test for Windows 95/98/ME and
Windows NT/2000. In Windows 9X/ME it uses a special kernel mode VXD to get
maximum accuracy by bypassing the file system. A similar mechanism is used in
Windows NT/2000/XP. HD Tach reads from areas all over the hard drive and reports
an average speed. It also logs the read speeds to a text file that you can load
into a spreadsheet and graph to visually read the results of the test.

The Western Digital Caviar Black WD1001FALS hard drive burst data read rates
are very high. When it comes to random data access however, the results are
largely flat regardless of RAID 0, RAID 1 or single hard drive
configuration.
