    Samsung 980 Pro NVMe SSD review: PCIe 4.0 for the win

    The Samsung 980 Pro is right here to take again the crown—after which some. While its predecessor, the 970 Pro, received and finally misplaced its SSD efficiency title to hotter competitors, this newest technology buries all of them.

    Of course, to witness the greatness, you’ll want a pc with the PCIe 4.0 device interface, which presently means late-generation AMD Ryzen. With PCIe 3.0, the 980 Pro remains to be glorious, however merely on a par with the highest competitors.

    This evaluation is a part of our ongoing roundup of the best SSDs. Go there for data on competing merchandise and the way we examined them.

    Design and specs

    The 980 Pro sports activities the identical 2280 (22 mm huge, 80 mm lengthy) kind issue as all mainstream NVMe SSDs, and it arrives naked—no warmth spreader included. 

    The controller is a Samsung in-house Elpis design. The NAND is Samsung’s TLC V-NAND, which the corporate refers to as 3-bit MLC. Samsung knowledgeable me that there are “1xx” layers within the NAND. What the heck which means, I can’t inform you, however with 40 p.c extra capability it possible means there are round 128 layers.

    The DDR4 DRAM cache varies by capability. You get 512MB of cache on the 256GB drive ($90 when it turns into accessible) and 512GB drive ($150 when accessible), and 1GB of cache on the 1TB mannequin we examined ($230 when accessible). The yet-to-be-priced 2TB mannequin can have 2GB of cache.

    Those sticker costs place the Samsung 980 Pro within the higher tier of NVMe SSDs by value per gigabyte. In quick, it’s costly. The drives carry a five-year restricted guarantee. The restrict is 150TBW per 256GB of capability score. TBW stands for TeraBytes Written over the lifetime of the drive.

    That score is a bit low for a premium-priced drive. Still, it represents 41GB written per day over 10 years—much more knowledge than the common consumer will write (reads don’t depend). A big a part of the logic behind tying warranties to TBW scores is to discourage enterprise use of cheaper client SSDs.

    Samsung

    Samsung’s 980 Pro blows away each NVMe SSD we’ve examined when used together with PCIe 4.0. With PCIe 3.0, it’s nonetheless top-notch, however not practically as spectacular. Especially given the value and considerably low TBW score. 

    Performance

    The 980 Pro greater than lived as much as Samsung’s claims of 7GBps studying and 5GBps writing by way of PCIe 4, at the very least with CrystalDiskMark 6, which we use for comparability with a big physique of earlier testing. Real-life transfers can’t contact any of the artificial outcomes, as Windows has change into a fairly giant bottleneck in efficiency, however the 980 Pro nonetheless aced them.
