Take 1TB and divide it by two and you've got a pair of new 2.5-inch 500GB disks just introduced by Fujitsu. Fujitsu's MJA2 series of 9.5-mm tall, SATA 3.0Gbps, 5400 RPM disks consume just 1.4 watts during read/write -- that's a 33% reduction from its previous drives while still boosting transfer rates by 27%. Model MJA2 CH even adds the world's first automatic, full-disk, 256-bit AES encryption without any performance penalty due to the hardware level of encryption. Take that Seagate and your weak-sauce 128-bit key. To be fair, any successful attack on a 128-AES key would likely apply to a 256-bit key as well. Expect these to pop for retail (with Western Digital branding too, presumably) sometime in the first quarter of 2009, a bit earlier if you can do without the encryption.
