What's the fastest internal hard drive on the market? I understand that SSD is slower on write but super fast on reads. What about 10k RPMs? Is that as fast as we've got now?

RPMs are one factor. There's also the data transfer rates. Note that for many years Seagate SATA drives came with a jumper pre-installed that limited the speed to a maximum of 3G/s and removing it would supposedly allow for transfer rates of up to 6G/s (although I did notice an improvement in speed when transferring files that were multiple GBs in size, it wasn't double the speed, but the SATA controller surely would have been a factor too). – Randolf Richardson Sep 23 '11 at 23:20

Apparently, the only drives that get close to saturating the 6 gb/s bandwith of Sata 3 are SSD- Some get up to 500-600 mb/s with sata 3s.They arn't slower on write, but they wear out. Depending on your needs/budget, there's also drives than hang off PCIE, that are faster.
