Western Digital SiliconEdge Blue 256GB SSD Review - WD enters the SSD market
Introduction and Specifications
Back in March of last year, Western Digital plunked down a cool $65 Million to acquire Silicon Systems, an SSD maker tailoring to the embedded and enterprise markets. In less than a years time, Western Digital integrated their teams with those from Silicon Systems and produced their first consumer grade SSD.
After dozens of internal firmware revisions and over a hundred thousand hours of internal testing, the SiliconEdge Blue emerges:
An SSD with a HDD manufacturer's logo on it. I never thought I'd see the day.
The specs list a 5,000 IOPS rating, which seems way low when compared to an Intel X25-M G2's rating of 35,000 IOPS at the same 4KB random reads. I was a bit skeptical at their stated spec being as low as it was, so I did a few quick checks before the suite:
IOMeter shows slightly under 5,000 IOPS for 4KB random reads.
ATTO shows 76 MB/sec for 4K random, which works out to slightly over 4,000 IOPS. The fact that we're still at the same 5,000ish at ATTO's default Queue Depth of 4 suggests this drive might not scale with higher Queue Depths like Intel, Sandforce, and Marvell is capable of. Before we got into the benches, the Silicon Systems controller wasn't looking to be as spectacular as I'd hoped. As a matter of fact, this ATTO run looks more like lesser performing controllers such as Samsung.

Well, we're not sure what to expect, so lets get through the full suite and see what happens.
