bubbaQ Posted January 18, 2010 Share Posted January 18, 2010 WD 2TB EARS drives w/ 64MB cache in stock at Newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16822136514 Link to comment
bubbaQ Posted January 21, 2010 Author Share Posted January 21, 2010 BTW, a little research reveals another difference between the EADS and EARS drives -- the idle power usage of the EARS drives is same as read/write power usage... whereas the EADS drives have about a 50% drop in power consumption when idle.

dib Posted January 23, 2010 Share Posted January 23, 2010 Power usage from the WD site for the EARS drives. If these are true it looks like only the 1TB drive has the same idle and read/write power usage. 1TB Read/Write 5.4 Watts Idle 5.4 Watts 1.5TB Read/Write 6.00 Watts Idle 3.7 Watts 2TB Read/Write 6.00 Watts Idle 3.7 Watts Link to comment
bubbaQ Posted January 23, 2010 Author Share Posted January 23, 2010 If these are true it looks like only the 1TB drive has the same idle and read/write power usage. I noticed the same thing after some more research. I also saw some blurbs that the EARS 2TB was actually a 6Gb/s drive internally, and a 6Gb/sec version was going to be released. Link to comment
WeeboTech Posted January 23, 2010 Share Posted January 23, 2010 Interesting, I was expecting it to perform better. Link to comment
bubbaQ Posted January 23, 2010 Author Share Posted January 23, 2010 Well with four 500GB platters, there is certainly more data per revolution than the 1TB drives.... so that is a plus. I don't know that the 64MB of cache will make a lot of difference in the types of benchmarks you see published.... there is a point of diminishing returns. Nirvana would be a drive where we had access to tweak the read-ahead algorithm on the drive itself! Link to comment
