Storage Review has a pretty good process and reviewed the M500DC when it released last year. http://www.storagereview.com/micron_m500dc_enterprise_ssd_review

 

The only database-specific info we have available are for Cassandra and MSSQL:

(some of that info might be relevant)

 

In terms of endurance, the M500DC is rated to 2 Drive Writes Per Day (DWPD) for 5-years. For comparison:

Micron M500DC (20nm) – 2 DWPD

Intel S3500 (20nm) – 0.3 DWPD

Intel S3510 (16nm) – 0.3 DWPD

Intel S3710 (20nm) – 10 DWPD

 

They’re all great drives, the question is how write-intensive is the workload.

Intel added a new product, the 3610, that is rated for 3 DWPD.  Pricing looks to be around 1.20$/GB.
