Best hard drives


Below are the tables of the best (IMHO) HDDs and SSDs on the market now. (Contact me is you think I've missed some)

Note:
Bucks for the bang = Price/Capacity/Speed/IOPS*10000
Drives in 1.2GB/s array - number of drives for guaranteed 1.2GB/s array transfer speed = 1200/(Min. transfer rate) + 1

Note: OCZ Vertex II and other SandForce-based SSDs are not listed here because their productivity depends on the type of data (much better on highly compressible data and much worse on uncompressible). Unless the tests with different data types run it's impossible to rate them properly.

Note: the table shows that the drives with over 0.3 "Bucks per the bang" are ether outdated or overpriced (whatwver othe advantagies they have).
