It transpired after several 48GB transfers, followed almost immediately by a TRIM operation, and then another 48GB single file copy. I saw this once while testing the 256GB model.

If you happen to catch the drive while it’s doing housekeeping, or there’s not enough NAND left (if the drive is nearing full) to assign some as secondary cache, write speeds can drop as low as 350MBps. This mild drop from 2.25GBps to 1.75GBps occurred at the 30%/135GB mark. We noticed this on the 450GB copy shown below. If you throw enough data at the 980 Pro, write speeds will drop from 2.25GBps to around 1.75GBps.
SAMSUNG NVME DRIVER V1.4.7.16 PRO
If you’re lucky enough to have a Ryzen and PCIe 4, you’ll love the 980 Pro which shaved more than a minute off of the previous fastest aggregate 48GB transfer time. The real-world 48GB transfer results below are also very impressive, and make the 980 Pro the first PCIe 4 drive we’ve tested to exhibit a real world advantage in sustained transfers. The 980 Pro is also fast with PCIe 3, but not enough to warrant the premium price. The 980 Pro is far faster than the Phison-based Seagate FireCuda 520 in this test, and our 48GB transfer tests-with PCIe 4. It was duly tested and performs almost exactly on par with the 1TB version. Samsung sent the 2TB version of the 980 Pro to us on. Especially given the price and somewhat low TBW rating. With PCIe 3.0, it’s still top-notch, but not nearly as impressive.

Samsung’s 980 Pro blows away every NVMe SSD we’ve tested when used in conjunction with PCIe 4.0. A large part of the logic behind tying warranties to TBW ratings is to discourage enterprise use of cheaper consumer SSDs.

Still, it represents 41GB written per day over 10 years-a lot more data than the average user will write (reads don’t count). That rating is a bit low for a premium-priced drive. TBW stands for TeraBytes Written over the life of the drive. The limit is 150TBW per 256GB of capacity rating. The drives carry a five-year limited warranty. Those sticker prices place the Samsung 980 Pro in the upper tier of NVMe SSDs by cost per gigabyte. The yet-to-be-priced 2TB model will have 2GB of cache. You get 512MB of cache on the 256GB drive ($90 when it becomes available) and 512GB drive ( $150 on Amazon Remove non-product link), and 1GB of cache on the 1TB model we tested ( $230 on Amazon). What the heck that means, I can’t tell you, but with 40 percent more capacity it likely means there are around 128 layers. Samsung informed me that there are “1xx” layers in the NAND. The NAND is Samsung’s TLC V-NAND, which the company refers to as 3-bit MLC. The controller is a Samsung in-house Elpis design. The 980 Pro sports the same 2280 (22 mm wide, 80 mm long) form factor as all mainstream NVMe SSDs, and it arrives bare-no heat spreader included. Go there for information on competing products and how we tested them. This review is part of our ongoing roundup of the best SSDs. With PCIe 3.0, the 980 Pro is still excellent, but merely on a par with the top competition. Of course, to witness the greatness, you’ll need a computer with the PCIe 4.0 device interface, which currently means late-generation AMD Ryzen. While its predecessor, the 970 Pro, won and eventually lost its SSD performance title to hotter competition, this latest generation buries them all. The Samsung 980 Pro is here to take back the crown-and then some.
