Perhaps it’s the first party manufacturing of NAND which gives SK Hynix some inside knowledge for optimization, or the 128 layer design or their controller is a bit newer? (Note there is a newer version of the SN750, but our performance is close to the published specs for the SN750 on the WD site). The performance difference between these two on these on the Crystal Disk Mark test is small, around 5% – 10% or so, but it does seem to exist. Both have a 5-year warranty, which is not bad either.
These sorts of NVMe Gen 3 storage devices have generally reached a performance level that is quite good enough for most average use cases. This SK Hynix Gold P31 seems especially well suited to average and above average uses for desktop situations based on these performance metrics. Especially considering our CDM tests at several queue depths, single threaded, actually exceed SK Hynix’s claimed performance of 3,500MB/s read and 3,200MB/s writes.
If you are in the market for a well performing drive, which compares favorably to respected competition, do also consider the P31 Gold 1TB from SK Hynix. The regular retail price for our 1TB test unit is already competitive at around $135. But timed to start with Amazon Prime Day on the 21st and 22nd of this month they’ll be going on sale for 20% off. Oh yeah.
