SiSoft SANDRA 2010
Testing continues with SiSoftware's SANDRA XII, the System ANalyzer, Diagnostic and Reporting Assistant. Here, we used the Physical Disk test suite and provided the results from our comparison drives. The benchmarks were run without formatting and read performance metrics are detailed below. We also included SANDRA's graph so you are able to see how the drive performs over time along with the average rated result.
The Barracuda Green posted a read speed of 106 MB/s, while the Caviar Green only hit 100 MB/s. It's worth noting that while the 7200 RPM models we tested were clearly faster, the performance gap isn't as wide as one would think. The RE4 scored 110 MB/s while the XT got up to 112 MB/s, only 4 to 6% quicker than the Barracuda Green.
SANDRA's write test reveals a substantial edge for Seagate's Green drive. It reached a speed of 101 MB/s, while WD's Caviar Green could only muster 72 MB/s, a 40% deviation. So far, a trend is appearing between the performance results of the Green models. Read speeds are similar but the Barracuda Green writes data more efficiently. Let's see if this holds true in the following tests.
