Desktop Test System
HD Tach Sequential Performance
Although not designed for desktop use, we still wanted to run a couple of tests to get a better understanding of how AllFrame Technology works. Right at the start, we noticed a difference in the way the drive reads and writes sequential data. Normally with HDDs, we see a curve with the drives performance dropping off significantly as the heads move from the optimal area on the platter.
With the Purple, we see the read performance start to drop off but then increase again. The write speed doesn't drop off like an HDD at all. The write test reminds us of what we see testing SSDs in a degraded state.
AIDA64 64KB Latency
Read Latency 64KB
Write Latency 64KB
The large 64MB buffer keeps the latency steady while reading and writing the span of the drive.
