To help you find the best plan for your needs, we've split up users into the following common profiles and provided recommended plans for each. Note that many ISPs have more plans than we could list in the table. We chose to only include the plans from each ISP that were the most competitive compared to the rest of the industry. This means there might be a more suitable plan for you that we didn't list, so be sure to check out the complete range of plans from an ISP if you don't find a good fit.

Why are we reviewing something that is a mere 36GB? Simple -- because this one drops access times and pumps up the transfer rate. Not targeted at the home user, the 36GB WD Raptor is marketed as an enterprise-level SATA drive -- the fastest drive on offer by WD. Capacity becomes an afterthought for the Raptor with its 10,000rpm spindle concerning itself with speed, resulting in seek times of around 5.2ms, compared to the 8.9ms of a 7,200rpm drive.

Just over four months on from our massive hard drive roundup (October 2002, page 74), and Serial ATA (SATA) hard disks have finally arrived. Phew.
