However, the real-world difference is not necessarily large, and endurance (as measured in TBW – terabytes written) is less of an issue in higher capacities. Newer drives based on QLC (quad-level cell) memory tend to be cheaper, somewhat slower, and offer less endurance than high-end SSDs based on TLC (triple-level cell) chips. Although prices vary somewhat day-to-day, it is mainly performance and the type of Flash memory used that determines the price tag. The number of alternatives has grown significantly since last year and there are now quite a few high-capacity drives available in all common form factors.Ĭost per GB is always a key factor when buying a storage device, and it is of course particularly important when shopping for a high-capacity SSD. Here, we’ve rounded up every 4TB or larger SSD we could find as of September 2021.
And thanks to the arrival of cheaper chips in the form of TLC (triple-level cell) and QLC (quad-level cell) NAND, it’s now easier than before to justify investing in more spacious drives. Nevertheless, the cost of Flash memory has been dropping for some time. The major stopping block is the high cost for end-users. While we are now starting to see some 8 TB variants, 4 TB SSDs are still much more common in the consumer market.įrom the manufacturers’ perspective, building SSDs in large capacities is not an engineering issue. If you work with storage-heavy apps or simply want quick access to your complete Steam library, there is no substitute for a high-capacity SSD.
