Having reviewed the Samsung 990 Pro 4TB when it was released, we found it to be one of the best 4TB SSDs on the market and among the best SSDs overall. The 990 Pro boasts maximum sequential reads of 7,450 MB/s and sequential writes of 6,900 MB/s, with random reads/writes coming in at 1.6 million and 1.55 million IOPS, respectively, while endurance is rated for 2,400 TBW.
The Samsung 990 Pro 4TB is among the fastest Gen 4 SSDs available thanks to read and write speeds of up to 7450/6900 MB/s, almost maxing out the Gen 4 bandwidth. This M.2 NVMe drive comes in the 2280 form factor and holds enough capacity to store a large selection of your favorite games or files.
Random reads/writes come in at 1.6 million and 1.55 million IOPS, respectively, while endurance is rated for a respectable 2,400 TBW.
Samsung uses 236-layer TLC V-NAND to achieve its 4TB capacity, while also using a single-sided design, making the 990 Pro ideal for use in computers where space is a finite resource. When we tested the Samsung 990 Pro 4TB, we found it scored above the competition on almost every test. On 3DMark's storage test, it had the lowest latency result, a big plus for responsive load times in gaming.
The Samsung 990 Pro is also excellent at sustaining strong write performance. In our IOMeter sustained sequential write tests, the 4TB 990 Pro was able to maintain a speed of 6.2 GB/s for 75 seconds thanks to its generous 10GB of pSLC cache. Once the data spills over into the TLC, it operates at 1.6 GB/s. The Samsung 990 Pro is also a leader in power efficiency, delivering 421.1 MB/s per watt. That number puts it ahead of all competitors but the Addlink A93 4TB and Lexar NM790 4TB.
The Samsung 990 Pro is certainly nowhere near the all-time low prices of years gone by, and I'm not sure at the moment when, if at all, we'll ever see those low prices again on storage, certainly not for some considerable time. If you want 4TB of storage now, then the Samsung 990 Pro is a formidable choice; just try to grab it when there's as much of a discount as possible.
