fingers and faces on top of whatever authentication measures your operating system offers. But, without some kind of encryption, the drives inside are left completely vulnerable to anyone with a screwdriver. Seagate has been combating that with its AES-packing Momentus Full Drive Encryption disks for years, finally updating the range with a suite of larger and faster models. The first is the Momentus 5400 FDE.3, a 5400RPM drive with 8MB of cache available in 160GB and 320GB sizes. There's also the Momentus 7200 FDE, coming in the same two capacities but with twice the cache and, predictably, spinning at 7200RPM. Seagate's promising 500GB flavors soon, all with onboard AES encryption that doesn't impact boot times or overall performance. Just don't forget that BIOS password, yeah?
