Consumer grade SSD's

[jameskilbynet]

Does anyone have experience of using SSD repositories built with consumer grade SSD's. I personally dont think its a good idea for a number of reasons including lower write endurance limits. Handling of loss of power events and the chance of a URE.

If this went ahead the likely setup would be 22 2TB disks in a RAID6. Looking for any feedback good or bad

Pure Storage uses "consumer" SSDs for their enterprise SANs, and from what their engineers say, the issues surrounding reliability of "enterprise" vs "consumer" in the SSD markets have largely gone away. Originally, enterprise classed drives were all SLC flash which was considerably more expensive (but more reliable) than the MLC flash being used in consumer drives. Now, even enterprise drives that most of the enterprise SAN vendors sell are MLC.

Yes Pure do however they have a lot of intelligence built into the controller layer to mitigate against some of the shortfall. Thanks for the input. useful in building a consensus
