February 18, 201115 yr Was $179.99 Now $169.99 With promo code EMCKHJC23 $159.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16822136792&nm_mc=EMC-IGNEFL021711&cm_mmc=EMC-IGNEFL021711-_-EMC-021711-Index-_-InternalHardDrives-_-22136792-L01C Not a bad price for those of you looking for a new or extra parity drive.
February 18, 201115 yr I don't know if I'd call $160 for a 2TB drive that much of a good deal as it's not really faster than a bunch of the Green drives except maybe for access time. My F4 2TB (I know, terrible drive, etc) is much faster than my 7200rpm drives.
February 19, 201115 yr I'm waiting for those prices to drop to $120 for those 2TB Black drives. It will happen, just a matter of time. Heck, maybe I'll wait until they go down to $100! Yahooooooooo. Prices on hard drives seem to be not moving as fast as they usually do though.
February 19, 201115 yr It's easy for a newer drive with higher density (F4) to be faster than older drives with lower density (your old 7200rpms) even if the RPMs are different. You need to compare within similar densities for an accurate picture of performance.
February 19, 201115 yr I need a good lesson on density stuff. I really don't know all that much about it and how it affects speed. I also have no idea what density my current drives are and how to find out.

You need to compare within similar densities for an accurate picture of performance. Do any of the newer 7200rpm drives use 667GB/platter or are they still using 500GB/platter? If the former than they will most definitely be faster than the 667GB/platter Green drives.
February 19, 201115 yr I need a good lesson on density stuff. I really don't know all that much about it and how it affects speed. I also have no idea what density my current drives are and how to find out. If you imagine the disk head, and the disk spinning beheath it, the more tightly packed the data, the more data the head will see in a unit of time. So a disk spinning at 5400 RPM with a aerial density of 667 will be able to deliver data faster than a a disk spinning at 7200 RPM with an aerial density of 200. There are two different "dimensions" of aerial density. One is being able to pack more data onto a single track, as we just discussed. The other dimention is the actual number of tracks. If one disk had 100 tracks before, and another has 150 tracks (disks have many more tracks than this, this is just asn example), the capacity could increase with no increase in speed. But in reality, as the aerial densities increase, manufacturers are able to have more data per track and more tracks. I did some searching the other day to try to find a reference to drive densities and # platters for current 2T disks. I didn't have much luck. Maybe someone else has a link they can post.
