Semi-OT: A word of friendly warning: I recently bricked a 120GB Intel 520 w/ the latest firmware (not sure if it was 400i) w/ ext4 on Fedora 17/x86_64. (Second bricked SSD in 12 months) A *very* short power shortage crept under my APC UPS and bricked the SSD. Amazingly enough, the power shortage didn't crash the machine - which continued working off the main HDD software RAID array. Luckily for me I rather distrust SSDs (see below) and use it as fast cache-of-sort, so I only lost a couple of hours of work. IMHO SSDs have one huge drawback: Unlike HDDs that can be partially recovered from more-or-less any type of damage by recovering data around bad sectors or replacing a fried controller board, SSDs complex write scheme and complex firmware usually means that any type of damage / firmware error / etc usually bricks it with more or less zero chance of getting the data back. On the top of that, we (as in all of us) have 40+ years worth of experience in predicting the life cycle (and death) of HDDs. There's far less information about the life cycle of SSDs. In short, backup. A lot. - Gilboa _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
