Seagate ST1000DX001 1TB 3.5" Desktop Hard Drive

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.

The Seagate ST1000DX001 offers 1TB of storage and has 8GB of MLC NAND flash memory for its solid-state portion. This Seagate 1TB SSHD has a Serial ATA 3.0 interface with NCQ support, 64MB cache, and a seek average speed of less than 9.5 milliseconds for both reads and writes. The average data read speed overall for the hybrid drive is 156MB/s and the average data read speed from the NAND flash media specifically is 190MB/s.

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 or 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.
