[QUOTE="jt1968, post: 1521017, member: 301307"] I've only fooled around with installing SSD drives in Win-doze gaming PCs, but I can tell you that an SSD drive will ALWAYS be faster than a mechanical HD in the same system. SATA III SSDs are typically up to 3 times faster on both read and write operations than a mechanical HD. I am unfamiliar with which MAC models and OS versions support the TRIM command (SSD optimization), but I do know that only Windows 7 and Windows 8 support TRIM. TRIM is necessary if you want to not have to buy a new SSD within a year or so - TRIM keeps track of which areas of the hard drive have already been used and erased, which is important considering that most SSDs have a typical life of 10,000 write/erase cycles over the entire drive, and it doesn't write to a previously erased area again until all other areas have been used once - this makes the SSD last several years. On the other hand, mechanical HDs can be written to and erased for years and years without worry. So you'll need to decide if you want blistering speed (SSD), or long-term reliability (mechanical HD). For me, I prefer the speed, and with regular Time Machine backups, I don't worry about the SSD failing in my MBPS w/ Retina. [/QUOTE]
