The new hybrid went on sale today, I ordered a 500GB. Figured I would let you guys know how it works out. Here's some numbers with my traditional Seagate 500GB 5400RPM in my 13" Macbook Pro Restart: 48 Seconds Launch Photoshop CS4 (following reboot): 18 Seconds Transfering a 1.4GB file from a Sandisk Cruzer (Flash Drive): 58 Seconds * I will update as soon as the XT arrives. The reviews make it seem like a great alternative to an SSD. 2.53 Core 2 and 4GB Ram. Leopard not SL.
