I bought a ST Express Ram Cache drive back in 2012 and it failed within a month. I know the RMA drill and had it replaced, the new one lasted until March of last year. Bought a new one a few days later, which died in July and the replacement died last month (finally got the second replacement a few days ago). It's hard not to be a little paranoid, since I still have some much older Sandisk Cruzer drives that have been used just as heavily until they became dedicated OS installers. I'm wondering if anyone else has noticed an unusually high failure rate for this brand or the Express RC family. Maybe it's just the nature of super fast flash media?
