I just yanked a pair of Intel X25 SSD disks after less than six months of daily use. They ran as a RAID 0 pair in my daily driver PC. I think I hosed them by trying a apply restore images to recover from an un-bootable system. As the article says, the more you write small files over an SSD, the more internally fragmented it becomes. (And no, you should never use a defrag utility on SSD's.) The SSD drives were Intel X25M engineering samples, so your milage may vary. But read the article anyway before dropping your hard-earned cash on the barrel head.
So, as Joe posted below about SSD prices dropping, beware a technology bargain you do not understand. I'll try to recover the SSDs after I rebuild my system with a conventional hard drive.
