SSD Drive Shootout! NVMe vs SSD 3DNAND vs Mechanical Speed Comparison

I decided to do a SSD speed comparison of the drives I have installed lately.

This SSD speed comparison includes M.2, 2.5 and 3.5 drives. NVMe, SSD,  and Mechanical. I thought I would take all the stats and pop them in a spreadsheet and chart them for reference.

Here are the drives I tested:

M.2 Drives:

M.2 NVMe XPG AData SX6000NP 128GB
M.2 SSD 3D NAND  Western Digital BLUE WDS250G2BOB 250GB

2.5″ SSD:

2.5″ SSD 3D NAND Western Digital Blue WDS500G2B0A 500GB
2.5″ SSD 3D NAND AData SU650 240GB
2.5″ SSD PNY CS1311 240GB
2.5″ SSD Silicon Power S55 120GB
2.5″ SSD 3D NAND Team Group L5 Lite 480GB T253TD480G3C101

Mechanical Drives:

2.5″ Mechanical Western Digital Scorpio Blue WD5000BPVT 500GB
3.5″ Mechanical Western Digital WD10EZEX-00WN4A0 1TB

Higher numbers are faster read/write times. So larger numbers are better.  The columns are sorted by fastest read or write times. The first column is not always the same drive. I am not sure if this is the best way to present this in a chart, or if I should have left the drives in the same order on the chart. I may update the graphs in the future. Just be aware.

Seq Q32T1 (This would be a sequential read/write like a large movie.)

4KiB Q8T8 (Smaller 4K size files.)

4KiB Q32T1

4KiB Q1T1


What did we learn here? I guess that I spend to much time doing things like recording data of the drives I get :-).

Besides that, its pretty much what you would expect. NVMe is the fastest, and Mechanical drives are painfully slow. If you haven’t switched over to a SSD as your boot drive I highly recommend it. The WD 3D Nand M.2 drive was faster then the 2.5′ version. Not sure if all M.2 are faster like that. As for the bang for the buck, the Adata SU650 and Team Group L5 Lite were very reasonable priced. I think they would be the best in that category. Prices do fluctuate a lot on drives, so it pays to shop around.

As I get more drives I will continue to fill out my spreadsheet and graph them here.  Hope this helps someone out there.

NOTE: The 2.5″ and 3.5″ were mainly tested on my Desktop which is using ATA 3Gb/s. You may see faster speeds if you use ATA 6Gb/s. The PC’s these were going into also were ATA 3Gb/s.

Have a great day!

BTW – This is my chart so far.
