About a year ago I had a new vendor ship about twenty computers to my company. They were supposed to contain Intel SSD's but instead contained Kingston drives. All of those drives failed within a year. As they fail I have been swapping them out with Intel drives and they just chug along nicely after that. I even took one of the RMA'ed Kingston drives and put it in my laptop to see how it did. It made it four months and failed just last week.
Here's what that failure looked like. It started off where the aystem would just freeze up for a couple of seconds about once a day or so. After a week that started happening more like once an hour, but the system would always come to life again, it would just pause for 10 seconds or so. Then after about another week it started hanging completely. First once a day, then several times a day requiring holding the power button down and restarting the system. Then I RMA'ed it.
The original drive was a kingston ssdnow 100, and lasted 11 months, the replacement was a ssdnow v200, it lasted 4 months. They just shipped me a replacement today, we'll see. It may go straight on ebay!
