> Don't all enterprise SSDs come with their own backup capacitors? Yes, but the cost of such drives makes rolling the dice with consumer grade drives appealing to some[1]. From the same thread, here's a word of warning from a Stackoverflow devops engineer[2] wrt to lack of capicitors on consumer grade drives and the perfect storm that can occur when UPS goes down in a power failure (unlike with spinning disks hardware RAID is unable prevent data corruption/loss in this case).

I think my consumer-grade Intel S3500 SSD have some kind of power-loss protection. I don't think that professional devices are 100% fail-proof either. I vaguely remember some test where they setup a test with forced power failures during heavy writes, and they zapped all drives but a few eventually. Something that worried me was that the failure mode quite often seemed to be a totally bricked SSD.

  > I think my consumer-grade Intel S3500 SSD have some kind of power-loss protection. The fine-print is important here. Crucial (IIRC) advertises some of its low-end consumer series with power-loss protection… against internal data corruption of the Flash Translation Layer. AKA "We won't completely brick the entire device if you pull power!" Err… thank you? Why are you advertising this as feature?

    Because OCZ SSDs used to have a failure rate of more than 50% caused by powerloss.

      Really,if this is true I don't think I will buy another OCZ SSD. Which brand is the best for reliability right now?

        OCZ already went bankrupt over that scandal and was bought up… in 2013.
