The Laptop (9.5mm) SSHD from Seagate has a 64MB Cache and like its younger sibling (Laptop Thin) comes equipped with 8GB of MLC NAND Flash. Apart from capacity and dimensions the specs for the two siblings are identical. At less than a year old the Laptop SSHD is relatively new, but like its smaller sibling its performance is unbalanced and favours small file IO. With average sequential speeds of 95 MB/s the Laptop SSHD lags the group leaders by over 50% at sequential IO. Small file 4K performance averages around 2 MB/s which is far better. Overall the Seagate Laptop SSHDs performance profile is skewed strongly towards small file IO. This, the 9.5mm 1TB version does represent better value for money than its smaller capacity 500GB sibling but neither of the drives are particularly strong sequential performers. [Jan '14HDrivePro]
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.
