Ok so i have been looking around the market and i found that i can buy a 1TB Hard Drive ( WD Blue 1TB Desktop Hard Disk Drive - 7200 RPM SATA 6 Gb/s 64MB Cache 3.5 Inch - WD10EZEX) for 53.99$ USD. But i found a 2TB Hard Drive (Toshiba 3.5-Inch 2TB 7200 RPM SATA3/SATA 6.0 GB/s 64MB Hard Drive DT01ACA200) for 69.99$ USD. I was wondering is 1TB enough storage or is it worth it to pay that extra like 17$ for another whole TB? The 2TB Toshiba also has SATA3 which idk if that is that important because i know everything has to be compatible to use SATA3. Thanks for the responses. And also if you don't mind answering this. What has to be compatible in order to use SATA 3 like if i wanted to use the SATA3 on the 2TB Hard Drive does only my Motherboard have to be compatible with SATA3?
