Our next set of tests simulates different enterprise-oriented workloads, including database, file server, Web server, and workstation configurations.
The database workload (also categorized as transaction processing) involves purely random I/O. Its profile consists of 67% reads and 33% writes using 8 KB transfers.
I have to say I was a little surprised at the outcome of this test. Not only does Micron's M500DC blow by the entry-level offerings, but it also maintains a clear advantage over the rest of the field, too. The drive's excellent write performance is enough to make for its lower read rate.
In the file server workload, which consists of 80% random reads of varying transfer sizes, the M500DC gives us another strong showing, only trailing SanDisk's Optimus Eco at high and low queue depths. In the sweet spot (a queue depth between eight and 32), the M500DC is a clear winner.
The Web server workload (100% reads of varying transfer sizes) exposes one of the M500DC's weaknesses: pure read-based transactions. At higher queue depths, it's only able to match the P400m, while trailing the other contenders by a wide margin.
Finally, the workstation benchmark (80% reads, 80% random) puts Micron's M500DC back near the top. While it consistently trails Intel's SSD DC S3700 and SanDisk's Optimus Eco, it clearly beats the rest of the field.
Overall, the M500DC performs well in our mixed workload tests, only falling behind on the read-only metrics. These results should be even higher if we retest using Micron's 240 and 480 GB models. I'd say this is a considerable accomplishment for a drive that owes a lot of its design to a cost-optimized consumer SSD.
