Since the R5 2400G was deployed, M.2 NVMe SSD prices have been level. SATA SSD prices have fallen slightly and hard disk prices have also fallen slightly. SSD products have rolled into larger capacity models as the average selling price for the Kingston A400 120GB has fallen below the cost of shipping.
M.2 SSD drive slots are now becoming more and more common making the market for larger capacity models more desirable. The Intel 660p SSD has continued to be less expensive compared to the Samsung 970 rival. M.2 2280 SSD products are limited mostly to 2TB due to the limited space available which is why many motherboards have two or even three M.2 slots.
PCI Express cards are another option for larger capacity and Intel offers their Optane storage in that format in addition to the more standard U.2 format. More recently Optane is being made in DC memory format sticks but these need special slots and BIOS support to be able to use the persistent storage capability. One 128GB stick would be perfect for the swap file but 256GB and 512GB capacities are also available.
Hard disks are good for media libraries etc. The growth in game libraries has motivated the need for larger capacity disks. Larger capacity disks have moved into the mainstream consumer market to keep up with growing needs.
PCI EXPRESS 4.0
Now that PCI Express 4.0 is available for AMD users already there are some vendors offering faster SSD products. PCIe 4.0 SSD products over 5 GB/s of bandwidth.
Prices for PCI Express 4.0 SSD products are about 75% premium at the moment but that should soften soon.
