[QUOTE="Randy B. Singer, post: 1196434, member: 190607"] They are fast! See: [url=http://www.tomshardware.com/charts/ssd-charts-2010/Desktop-Performance-Index-50-Throughput-25-PCMark-25-I-O,2364.html]Charts, benchmarks SSD Charts 2010, Desktop Performance Index (50% Throughput, 25% PCMark, 25% I/O)[/url] SSD's tend to be far less prone to failure due to jarring and impact as traditional hard drives are. But SSD's are prone to wear-out in time, and, especially when used in a Mac, can suffer from poor handling of bad blocks. OS X 10.6 and earlier don't support TRIM: [url=http://en.wikipedia.org/wiki/TRIM]TRIM - Wikipedia, the free encyclopedia[/url] I keep on hearing about SSD's having abnormally high failure rates and unusual problems: [url=http://hothardware.com/News/SSDs-Have-High-Failure-Rate/]SSDs Have High Failure Rate? - HotHardware[/url] [url=http://www.techradar.com/news/computing-components/storage/ssd-failure-rate-is-10-20-per-cent--268368]SSD failure rate is '10-20 per cent' | News | TechRadar UK[/url] (There were reports that Dell had as high as a 30% return rate for laptops with SSD's, which Dell refutes. However, Dell has refused to disclose the actual return rate.) I just recently learned that TRIM will be supported and implemented in OS X 10.7: [url=http://osxdaily.com/2011/02/25/mac-os-x-lion-supports-trim-for-ssds/]Mac OS X Lion Supports TRIM for SSD’s[/url] [url=http://osxdaily.com/2011/02/24/mac-os-x-10-7-lion-developer-preview-download/]Mac OS X 10.7 Lion Developer Preview is Available to Download[/url] So, if you are interested in an SSD, it might be best to wait until this summer when Apple releases OS X 10.7. By then SSD's might also be generally more reliable. ___________________________________________ Randy B.
