Just got a 750GB, 5200RPM (A little slow.. RPM speed, hopefully the density will make it up) Western Digital Blue hard drive. It cost me $159 (slightly higher price then I would've liked to pay) but I used my card which would give me a 3% back, so i saved somewhat... whatever. I need the space and already carrying a 17", I don't want a backpack full of 2.5" external drives. I spoke with a few people from Fry's (Whether or not you can trust them is your business, not mine) and they said that the 1TB model, they got the part numbers and such but never received a shipment for a couple of months now. So I'm guessing Western Digital built the 1TB models just only a few handfuls or none at all got the drives. I do know they made a custom port in their 1TB external drives, which makes it impossible to disassemble and put into a laptop. Here's a few pix, it's cloning my internal hard drive over right now. 430GB worth of files/apps/yadada.. I wonder how I even survived with 128GB off the MBA Here's the specs for you nerdier people =p Western Digital 750GB (WD7500KEVT) SATA 3.0Gb/s 2.5-Inch @ 12.5mm height / 1,465,149,168 Sectors 8MB Cache Average Latency: 5.7ms Rotational Speed: 5200RPM Average Drive Ready Time: 8 Seconds Load/Unload Cycles: 600,000 Read/Write Power Usage: 1.7W Idle Power Usage: 0.75W StandBy/Sleep Power Usage: 0.18W Average Acoustics (Idle): 24 dBA Average Acoustics (Seek Mode): 25 dBA I'll run any benchmarks you guys would like.
