The (WD20EZRX) is Western Digital's latest green drive. I don't see what's green about it considering that it draws 5.5 watts even when idle, which is about average nowadays. With peak sequential lab read/write speeds of 150 MB/s the performance profile is approximately 20% below average for recent Hard drive. It's not all bad news as the WD Green is priced aggressively so despite its relatively weak performance it still represents reasonable value for money, at least within the 2TB category. Due to economies of scale, larger capacity drives nearly always yield better value for money. Compared to the 3GB 7200.14 Barracuda, performance is very similar but the barracuda offers 50% more capacity for 36% more money. [Dec '13HDrivePro]
The ST1000DX001 is a Solid State Hard Drive (SSHD). There is 8GB of MLC NAND flash built into this model which helps facilitate better performance than a purely mechanical drive. The peak sequential read /write speeds of 190 MB/s are around 10% higher than average for a mechanical drive, but no where near typical SSD speeds. We have seen peak 4k write speeds as high as 5.72 MB/s, which is very impressive and to date the highest 4k read speed is 1.24 MB/s which is less impressive but still above average for a top end mechanical drive. The performance increases attributable to the NAND flash are primarily noticeable in the area of small file performance and the Seagate offers only marginally better sequential performance than other mechanical 1TB hard drives. Overall the ST1000DX001 is a very solid performer and bests the group average by 30%. The larger 2TB version (ST2000DX001) has similar performance but represents even better value for money.
