im buying a samsung 750 evo 120GB SSD as i need to save my precious data (combined size of the data is less than 70GB). i recently had a imation EXT HDD die on me while i was transferring some photos and songs....luckily the SATA to USB chip is still working only the HHD died. i read a few articles on the net and saw that using SSDs over USB deos not activate TRIM and that the SSD will die, i really need the fast speed of the SSD and the lower failure rates. please help me out!
