Recently the hard drive in my system started acting up...typical symptoms, slow boots, periodic lock ups, etc. We heard good stuff about a product called Scannerz which does hardware oriented analysis of hard drives on Macs (for details, see their web site at http://www.scsc-online.com ) Rather than going into a long and drawn out post about why my drive is failing, suffice it to say Scannerz pretty much indicated that the unit has problems. I could attempt the repairs they recommend which is to backup and reformat the drive and try it again, but the drive is 6 years old and probably used on the average at least 5 hour a day. I figure I could attempt a fix, but being as old as it is already, I'm thinking just to replace it. The prices of SSDs have dropped...still not cheap, but at least they're now affordable. I know that the wear leveling issues they've had in the past were supposedly fixed, so I started doing some research into them yesterday. What I found out was pretty shocking and to me, surprising. The following post that I found is one that seems to very common: http://windowssecrets.com/forums/sh...yields-answers-that-raise-troubling-questions I know that's a windows site, but if you do a google for "SSD Failures" there are not only a lot of posts about them, but videos on YouTube as well. What I would have THOUGHT would have happened is that some guy using his system as something like a database server hits the SSDs with so many writes that he would start to lose blocks, and as the SSD controller marks more and more of them bad, the performance degrades. That's what I THOUGHT would have happened. What seems to happen instead is that a lot of them (not just OCZ) just "give up the ghost" out of the blue, for no apparent reason. Because this technology, at least in mass produced consumer levels, is pretty new, I have to wonder if SSD manufactures have really gotten all the kinks out. Apple is now selling units with SSDs. Does anyone know if these are proving to be reliable? The idea of being able to boot in 10 seconds is appealing, but losing everything on the drive, having to send it back to the manufacturer, waiting for a return, and then re-installing it, possibly only to have the same problem occur over again is not appealing. Another question might be whether or not an SSD is even a good candidate for my system. I'm using an iMac C2D from 2006-2007. SSDs can pass data at much higher data rates than my poor old system can likely handle. My system uses SATA 1.X at 1.5Gbits/sec, whereas I think most if not all the SSDs support SATA 3.X at 3.0Gbits/sec. Are SSDs backward compatible with previous SATA versions? I would think they would be, but that's a guess. Another option that I might consider is an external RAID 0 with a FireWire interface. I'm interested in hearing opinions and options. Thanks in advance.
