I'm looking to add another hard drive and wanted to RAID the drives. However, my current drive is discontinued. What is the best 320Gb hard drive? Would RAID be faster than a single drive of a higher storage space?
I would just get a faster drive. RAID would still have the edge in benchmark speed, but you'll still see a good improvement with a newer drive and you won't have to worry about RAID.
I recommend this Western Digital 320GB..It's large, quiet, fast. It easily and perfectly fits where a 20-40-60-80 GB, 2.5" SATA drive would, including in a PS3.
