Solid-state drives that support the PCIe NVMe Gen 4 protocol do not possess the same read and write speeds, but the two SSDs that are currently on offer on Amazon operate at the absolute limit of this standard. Presenting the Samsung 990 PRO and the WD_BLACK SN850X, which are available in the 4TB storage capacity and can cross the 7GB/s performance bandwidth. Both PCIe NVMe Gen 4 drives are available at up to 57 percent off on the online retailer.
What is interesting about this deal is that these 4TB SSDs are available for $299.99, but the WD_BLACK SN850X gets the highest price cut compared to the 990 PRO, which is discounted by 35 percent. When talking about speeds, the SN850X can reach up to 7,300MB/s, while the 990 PRO’s read limit tops out at 7,450MB/s, and write speeds reach a maximum of 6,900MB/s. Thanks to such high speeds, any one of these 4TB SSDs can be used in the PS5, giving you ample storage to install those storage-guzzling games.
Keep in mind that you will only experience these speeds if these solid-state drives are outfitted in a compatible M.2 slot that supports the PCIe NVMe Gen 4 protocol. While the Samsung 990 PRO and the WD_BLACK SN850X are backwards compatible with the older PCIe NVMe Gen 3 standard, you will leave quite a bit of performance on the table if you use these slots. For desktops and laptops, installing either of the two is a seamless process, as all that is required to be installed is a mounting screw. In short, if you want the best of the best solid-state drive and you are not afraid to raise your budget, you cannot go wrong with these options.
