OCZs have a bad reputation due to a rather high failure rate compared to other brands, combined with SandForce controller issues. Most of the problems with the SandForce controllers have been resolved with firmware updates, but the OCZs are still not the best choice for reliability, a lot of them still suffer from a high failure rate.
Intel is quite reliable, but their drives tend to be more expensive than their competitors. You can usually get more performance and decent reliability for less money with someone other than Intel, so unless reliability is your paramount concern, you can get better value elsewhere.
so which hard drive would you say i could definitely buy specifically ( brand and model) for the price, reliability and performance?
