I've had bad experiance and good. (I'm sorry Les but I'm going to contradict you [absolutely no offense intended]) I just have had experiance in diametric opposite to what your suggesting. We used to run a machine [centroid, which operates on a linx box] that used an SSD and we replaced it [SSD] 6 times [IIRC] because of it failing or becoming corrupted. After that I was super leary of using SSD's on anything but was heckled into trying it on a personal machine that I built in Jan of 2011. It's a Raid 5 setup where there are three drives and while I have had to recover once [I didn't change the drive out, I just asked it to recover the data and it was back working & still is using the same drive] I've not had a spec of trouble otherwise. It's running Win7. I'm building a new box for my mill and have bought a single SSD for it, because I will only ever use that box for running my mill, I am ok w/ the increased risk as recovery of the data for the mill is not a large concern [easily backed up and restored]. It takes longer to re-integrade it into my network than replace the system data for running the mill. Should I have problems I'll look at going to a raid system etc. I LOVE the super speed of that machine, I've got the 7200rpm high Bit drives on other machines and it's slow as 80 weight oil on new years day by comparison. One thing that I feel makes a big difference when it comes to SSD's is the quality of the drives. I only use Kingston or Sandisk drives, I can't remember the name of the SSD's used in the centroid system but I do recall they were more 'generic' not something I would have looked at as a high-line product. I wouldn't say the issue was with the operating system however, I do believe the drive quality did have a large impact in this instance. Fwiw Jarrett Johnson
