A high-capacity SSD is essential if you work with storage-intensive software or simply want speedy access to your entire Steam collection. While 8 TB SSDs are becoming more widespread, 4 TB SSDs are still far more common in the consumer market.
Large-capacity SSDs are not an engineering challenge for manufacturers. The high cost for end-users is a key stumbling factor. Despite this, the price of Flash memory has been falling for quite some time. And, thanks to the introduction of cheaper chips in the form of TLC (triple-level cell) and QLC (quad-level cell) NAND, justifying the purchase of larger drives is now easier than ever.
We’ve gathered every 4TB or larger SSD we could discover. Since last year, the number of options has increased substantially, and there are now a plethora of high-capacity drives available in all common form factors.
Cheap and Affordable 4TB SSDs
When purchasing for a storage device, cost per GB is always a significant consideration, and it’s much more so when looking for a high-capacity SSD. Although costs change from day to day, the price is primarily determined by performance and the type of Flash memory used. Newer SSDs with QLC (quad-level cell) memory are less expensive, slower, and have less endurance than high-end SSDs with TLC (triple-level cell) memory.
However, the real-world difference isn’t always significant, and increasing capacity make endurance (measured in TBW = terabytes written) less of a concern. At the time of writing, these are the most economical 4TB SSDs in the M.2, 2.5′′, and portable form factors.
The WD Blue is a well-reviewed 2.5-inch SSD with good performance (for a SATA disc) and long-lasting TLC NAND. M.2 PCIe/NVMe SSDs are generally more expensive, but Mushkin’s Alpha (which uses less expensive QLC NAND) is reasonably priced. If you need a 4TB portable SSD, the Crucial X6 is one of the most cost-effective options.

List of 4TB M.2 (PCIe/NVMe) SSDs
1. Fastest 4TB SSD: Seagate FireCuda 530
At the time of writing, the fastest 4TB M.2 SSD is the Seagate FireCuda 530, which was just released. It’s also the fastest M.2 drive in the world as of September 2021. It is based on the Phison E18 controller and uses Micron’s 172-layer TLC NAND memory, which is both quick and long-lasting (5,100 TBW). This, combined with sequential read/write rates of 7,300 MB/s and 6,900 MB/s, respectively, making it the ideal option if you don’t want to sacrifice capacity, endurance, or performance.
2. Fastest 4TB SSD: Sabrent Rocket 4 Plus
Sabrent’s Rocket 4 Plus is the fastest 4TB M.2 SSD at the time of writing. It, too, is based on the Phison E18 controller, but it employs an older type of TLC NAND memory, which means performance and endurance aren’t quite on par with the Seagate.
Nonetheless, the Rocket 4 Plus offers sequential read speeds of over 7,000 MB/s in a Gen4-capable system, with write speeds not far behind.
3. Excellent Endurance: Corsair Force MP510
The Force MP510 from Corsair has been on the market for a few years, but the 4TB capacity was only recently introduced. The MP510 is still a great Gen3 drive, and while its sequential performance isn’t as good as the Gen4 competitors, it mostly saturates the older interface. It also makes use of higher-end 96-layer TLC NAND memory chips and has a 6,820 TBW endurance rating (terabytes written).
