Seagate Momentus Thin ST320LT009 320GB 7200 RPM RPM 16MB Cache SATA 3.0Gb/s 2.5" Internal Notebook Hard Drive

Pros: Good solid performance, 7200rpm, HDD password based self-encrypting drive, no need for trusted platform module

Cons: Does not come in 500GB version, HGST version of the drive is not sold by newegg, not even sure if it's even available

Other Thoughts: Long-time (2+ year) user in their 9.5mm standard height 7200.FDE2 500GB drive in an Acer Timeline 1810T (also a great machine), had nothing but great things to say about that model. The Timeline replacement (Aspire V5) only accept a 7mm drive, so was forced to buy a new unit...boo. Only thing that fits the bill (FDE, non-SSD, HDD, made by Seagate) is this one. Priced at $80 USD as of Black Friday 2012, had to re-install Windows 7 to get a clean install into the machine. So far I am happy with it. Only wish that Seagate offers a 500GB version (I run a devy of VMs so more capacity is always better, or if SandForce SSD vendors are better at defining what their so-called encryption happened to be (or if it's actually priced better). I am sticking with HDDs, and this one looks like a winner.

Oh yeah. Newegg, you guys are rockstars. Fast shipment and great pricing - can a geek ask for more?
