Subject Re: SSD Experience (on developer machine)
Date Tue, 23 Aug 2011 15:20:21 GMT
Funnily, I had such an experience: an SSD on the laptop of the brand SanDisk, guaranteed for
80 TB of writes.
Well, I had it twice changed under guarantee. Then the shop provided me an OCZ.
Maybe that lasts longer... I'm still in guarantee.
