hi I need to replace my HDD which is failing. I decided to go down the SSD route. I keep getting rainbow ball errors with disk error s02 on the log. its been going on for a long time and has gotten worse. i've verified disk etc, nothings worked. i don't want super duper performance with super write speeds. any mid range decent SSD will do. my main problem i space, at a minimum i want around 200GB, preferably more in the 500GB range. can someone please recommend me an SSD: my budget is probably around £200-300 including enclosure and whatever else is necessary for the switch. can someone please help me out?
