A solid state drive is often the most important component for making a PC feel fast and responsive; any PC still using a mechanical hard drive as its primary storage is long overdue for an upgrade. The SSD market is broader than ever, with a wide range prices, performance and form factors.
This may be a bad time to try to buy a new GPU or CPU, but the consumer SSD market isn’t suffering from any shortages. SSD prices have mostly leveled out for the moment, though some prices continue to creep downwards. Most of the interesting recent activity has been in the high-end segment, where there is now stiff competition among top of the line PCIe 4.0 SSDs, and an increasing number of QLC-based drives that are helping make PCIe 4.0 a bit more affordable.
