Samsung’s ever-evolving SSD lineup has a brand new member within the type of the 990 Evo M.2 SSD. It debuted in January 2024 as Samsung’s first drive to have PCIe 5.0 help, making it a stable possibility for individuals who need the flexibility of each PCIe 4.0 and PCIe 5.0 compatibility. The added versatility mechanically makes it a greater possibility to contemplate over many different SSDs in 2024, however let’s learn the way it stacks up towards the 970 Evo Plus, which is the one different SSD that is accessible as part of Samsung’s Evo lineup in 2024.
Samsung 990 Evo vs 970 Evo Plus: Worth, specs, and availability
The brand new 990 Evo is cheaper, however solely is available in 1TB and 2TB choices
Samsung’s new 990 Evo SSD debuted in January 2024 as the corporate’s first M.2 SSD with PCIe 5.0 compatibility. You’ll be able to seize one in your PC proper now from Samsung’s official web site and a few third-party retailers like Amazon, Finest Purchase, and Newegg. It is solely accessible in 1TB and 2TB capacities proper now, although, they usually’ll value you $125 and $210, respectively. This explicit SSD is surprisingly seeing some reductions already, so hold an eye fixed out for these.
The Samsung 970 Evo Plus SSD is a PCIe 3.0 SSD that is been available on the market since 2019, when it changed its predecessor, the 970 Evo. The 970 Evo Plus is offered in 250GB, 500GB, 1TB, and 2TB capacities, which means you get extra storage choices in comparison with the newer drive available on the market. They’re all readily available for purchase from Samsung’s official web site and third-party retailers like Amazon, Newegg, and Finest Purchase. The 970 Evo Plus begins at $60 for the smallest possibility, however the 1TB and 2TB capacities that compete with the 990 Evo variants go for $140 and $240, respectively.
Let us take a look at the specs of SSD to learn the way they stack up towards one another on paper:

Samsung 990 Evo vs 970 Evo Plus: {Hardware} variations
Totally different controllers, up to date TLC NAND, and extra
Supply: Samsung
Each SSDs on this comparability are single-sided M.2 2280 drives that share a five-year guarantee and an identical Terabytes Written (TBW) rankings (for the 1TB & 2TB variants). Neither of those SSDs include an elective heatsink both, however that is just about the place the similarities between the 2 fashions finish. They each use completely different controllers which are primarily based on completely different interfaces, and also you’re additionally completely different NAND flash, completely different efficiency metrics, and extra. Samsung’s 990 Evo being the newer SSD on this comparability, makes use of the brand new 5nm Piccolo controller. The 970 Evo Plus — the revised model that is been accessible since 2021 — makes use of the 8nm Elpis controller.
The Piccolo controller, in case you’re questioning, is designed for the PCIe 5.0 x2 interface and is backwards suitable with the PCIe 4.0 x4 customary, whereas the Elpis controller is designed for the PCIe 4.0 x4, and it is backwards suitable with the PCIe 3.0 x4. The brand new 990 Evo additionally makes use of the up to date V6 Prime 133-layer 3D TLC NAND flash versus the older 92-layer 3D TLC NAND flash on the 970 Evo Plus. One other necessary distinction between the 2 is that the 990 Evo has a DRAM-less controller, and it takes benefit of the Host Reminiscence Buffer (HMB) for main caching. The 970 Evo Plus makes use of LPDDR4 DRAM of various capacities that ranges from 512MB to 2GB relying on the variant you choose.
Neither of them, as I beforehand talked about, can be found with a heatsink, which means you may both have to show to different Samsung SSDs just like the 980 Professional if there is no such thing as a SSD heatsink in your motherboard. Understand that the revised model of the 970 Evo Plus, which Samsung silently launched in 2021 with the up to date controller, is understood to run a little bit heat. Up to now, there have been no such studies in regards to the 990 Evo working scorching, so the dearth of a heatsink might not essentially be a deal-breaker.
Samsung 990 Evo vs 970 Evo Plus: Efficiency
The 990 Evo is decidedly quicker and extra power-efficient
Supply: Samsung
We’ve not had an opportunity to put in both of those SSDs in our testbench for thorough testing, however Samsung’s personal efficiency comparisons for the brand new 990 Evo SSD are towards the 970 Evo Plus, making it simpler to grasp the sort of enhancements you possibly can count on to see. The 990 Evo SSD is claimed to ship as much as 43% higher efficiency in comparison with the 970 Evo Plus drive. Not solely is Samsung touting improved sequential learn and write speeds, but it surely says the random learn and write speeds have additionally obtained a lift.
So far as the efficiency figures are involved, you’re looking at as much as 5,000 MB/s sequential learn, and as much as 4,200 MB/s sequential write speeds for the 990 Evo, whereas the 970 Evo Plus drive tops out at 3,500 MB/s and three,300 MB/s sequential learn and write speeds, respectively. The 990 Evo’s random learn and write speeds additionally get a lift with as much as 700K enter/output operations per second (IOPS) and 800K IOPS, respectively, up from 620K and 560K learn and write IOPS. It is spectacular to see this stage of efficiency enchancment with a DRAM-less design, and you may positively see some higher leads to actual world functions utilizing the newer drive.
The enhancements within the new 990 Evo SSD additionally prolong to the ability effectivity division, the place Samsung claims improved energy effectivity of as much as 70% when in comparison with the 970 Evo Plus. The 990 Evo is rated to devour as much as 5.5W, whereas the 970 Evo Plus consumes 6W on common when it is energetic. That mechanically makes the newer drive a extra favorable SSD for laptops, the place battery life is a large concern. Comparatively low energy consumption ranges additionally imply that the brand new SSD produces much less warmth as compared, as soon as once more making it that significantly better to make use of and not using a heatsink.
Earlier than we get to the conclusion, it is also price noting that the Samsung 990 Evo is extra versatile and future-proof with help for each PCIe 4.0 x4 and PCIe 5.0 x2 interfaces. Having the added versatility that is lacking in 970 Evo Plus will let you reserve PCIe 4.0 or PCIe 5.0 lanes for different {hardware}, relying on the elements that will want extra PCIe lanes.
Samsung 990 Evo vs 970 Evo Plus: Which SSD is healthier to purchase?
Samsung is pushing the 990 Evo SSD as an improve to the 970 Evo Plus that got here out a number of years in the past, and it is simple to see why. Not solely does the brand new drive ship higher efficiency, but it surely’s extra power-efficient, making it extra appropriate for individuals who need to change the SSD inside their laptops with one thing newer. The PCIe 4.0 and PCIe 5.0 compatibility additionally makes it extra versatile and higher suited to newer techniques. To not point out, the 990 Evo can also be cheaper than the outgoing mannequin, making it decidedly higher for these constructing a brand new system.

The 970 Evo Plus was once top-of-the-line SSDs when it got here out, but it surely’s beginning to present its age now. As such, it would not be my first choose for these constructing a brand new system in 2024. Sure, Samsung silently launched revised fashions of the 970 Evo Plus that carry the brand new Elpis controller with help for PCIe 4.0 x4 interface, however the speeds and the general efficiency stays principally unchanged from the unique launch candidate, making it barely slower than the brand new 990 Evo. The present 970 Evo Plus SSD customers may also profit from the enhancements seen within the new drive, however remember that the 990 Evo is not one of the best or the quickest PCIe 5.0 SSD on the market. So do not improve from a 970 Evo Plus to the newer drive, anticipating an enormous leap in efficiency.
