AMD users probably already have PCIe 4.0 on their boards but were turned off with the high price of PCIe 4.0 NVMe. Things are going to change with Intel joining the PCie 4.0 bandwagon with it’s Z590 chipset.
Other models of Gen 4 NVMe are the Sabrent Rocket NVMe Gen 4 and WD Black SN850 Gaming SSD.
The Sabrent Rocket NVMe Gen 4 looks way cheaper as you can get a 500 GB for the same price of USD 89.99. Although it runs on Gen 4, it supports speeds of up to 5000 MB/s (read) and 2500 MB/s (write).
WD Black SN850 Gaming SSD is another contender. The 500 GB retails at USD 119 and it offers speeds up to 7000/5300MB/s.
In terms of price, the Samsung (for the 500 GB) is a bit more expensive as compared to the closest competitor the WD Black SN850 Gaming SSD. * Prices quoted are from Amazon.com
If you are on the budget, the slower Sabrent Rocket NVMe could be a good choice as it provides a better dollar per gigabyte.
In terms of warranty, all manufacturer provides 5 years limited warranty (check their respective sites for details).
In Conclusion, NVMe performance is so fast that you probably even notice it. The choice is yours if you need a larger capacity or higher pricing for faster speeds. What would be your choice ?
I give the Samsung 980 Pro 250GB PCIe NVMe Gen4 SSD M.2 our editors choice award.
