Currently I am booting from the standard HDD that came with my mid 2011 iMac. It's really slowing me down so I am planning to get an external SSD as my boot drive. Trying to decide between: -LaCie Rugged SSD (500GB) -Samsung EVO SSD (500GB) [with an external enclosure/dock and ThunderBolt cable]. The drive will be staying next to my iMac (not worried about portability).The second option, "building" it myself, is cheaper (probably about $100). But I'll spend the extra $100 for premium performance. Performance wise, which option is best (faster speeds, no stalling, etc.) ? If the second option has similar performance, can you recommend some external enclosure/docks?
