Interesting, I didn't realise that was the case. I've seen various claims of SSD wearout times being 5+ years which means they would be obsolete before they wear out. > disk has worn out), and in our case the performance went to crap sometime > after the counter hit 1, causing considerable frustration to all involved. Do you know of any good software to measure performance changes in disks? Performance often changes before drives develop faults and it would be good to measure that. EG if the number of iops the disk delivers when it's neat 100% according to the iostat algorithm suddenly changes by an order of magnitude then it's probably due for replacement. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
