Statistics for SSDSA2SH064G (Intel X25-E with 64G, SLC)I always had a problem to figure out, if ssds are good or bad for databases. So in the end i just tried it out, keeping backups always handy, though. Until now no problems at all. I expect to get the first errors in a year. stats for one disk: WriteCacheSupport : Yes WriteCache : Disabled RLACacheSupport : Yes RLACache : Disabled SMARTFeatureSetSupport: Yes SMARTSelfTstSetSupport: Yes SMARTErrorLogSupport : Yes CmdQueuingSupport : NCQ CmdQueuing : Enabled CmdQueueDepth : 31 MultiDMASupport : MDMA2 UltraDMASupport : UDMA5 DMAMode : UDMA5 MediumErrorThreshold : 0 DataTransferred : 127.79TB ReadDataTransferred : 76.05TB WriteDataTransferred: 51.74TB Errors : 0 NonRWErrors : 0 ReadErrors : 0 WriteErrors : 0 IORequest : 1,175,466,806 NumOfMediumErrors : 0 NonRWRequest : 298,744 ReadIORequest : 1,934,104,533 WriteIORequest : 3,536,030,825 StatsStartTime : Jan 13, 2010 00:49:50 StatsCollectionTime : Mar 21, 2011 10:23:47 Stats for the raid6, that includes the disk above.
