I’m not saying this is the cheapest 4TB NVMe SSD deal available this Prime Day, but it’s really close, and Samsung offers speeds up to 7,250 MB/s with the 990 EVO Plus, making this $200 deal a must-have for anyone looking to expand storage capacity. Whether you have a laptop that could do with a noticeable performance boost or need somewhere to stash large files on network storage for running video editing software, Samsung’s EVO Plus is up to the task. This is still considered the sweet spot for storage compared to PCIe Gen 5, which can cost almost double for the same capacity.
Why this is the best 4TB SSD deal
In our comprehensive review of the Samsung EVO Plus SSD, we found the drive to offer reliable 7,250MB/s sequential write and 6,300MB/s sequential read speeds. These are some ridiculous numbers, even by 2025 standards, with PCIe Gen 5 drives rolling with 15,000 MB/s figures. You won’t have any trouble loading an entire operating system in seconds. The Samsung 990 EVO Plus range offers good random access performance and runs cooler than some other drives on the market, making this a solid choice for laptops and other compact devices.
You’ll struggle to find another PCIe Gen 4 SSD with this much capacity and reliable performance at such a low price. Not only are you able to save a considerable sum of money, but you’re also getting storage from one of the best brands in the business. Samsung has been making SSDs for years and knows a thing or two about producing flash storage. Although this may be a slightly more affordable SSD, you’ll find some excellent features usually reserved for other, more premium options. These include adaptive power management and temperature-based adjustments.
The Samsung 990 EVO Plus itself is backed by a 5-year warranty with an endurance rating of 2,400 TBW. That’s not bad for an SSD that costs less than $200, and should provide peace of mind that Samsung designed this drive to run hard and for longer. I doubt we’ll see a better deal than this for a 4TB SSD.
