Personal Tech Pipeline rounded up four pocket hard drives and put them through their paces so you don't have to. In their lineup: the Archos ArcDisk, Imation's Micro Hard Drive, Seagate's Pocket Hard Drive, and Sony's Micro Vault. Not suprisingly, they found that each had their ups and downs, with the Seagate (seen at right) probably the slight overall winner, thanks in part to the included software to make the drive bootable — although they do say it's too slow to be used as a general backup device. They also liked the ArcDisk as a more cost-conscious solution and the Imation for the security-minded. Their biggest knock against Sony's Micro Vault is the price: $230 for 5GB.
