Samsung 990 EVO

A power-sipping Samsung drive that's great for laptops and budget builds, but only if you catch it at the right price. At USD 170 it's a steal; at USD 449 it's a trap.

The sequential numbers are fine but not exciting. 5,000 MB/s read puts this in the 71st percentile for speed, which is solid but nowhere near the PCIe 4.0 monsters like the WD_BLACK SN850X. What surprised us is the random performance. One owner benchmarked 4K random reads at 46 MB/s and writes at 161 MB/s, which actually beats their 980 PRO. That's the HMB tech doing work. The DRAM-less design means it borrows 400-500 MB of system RAM, and sustained writes can get a little wobbly under heavy load. But for bursty workloads like game loads and app launches, this drive punches above its weight class.

The 990 EVO sits in an awkward spot. The Kingston Fury Renegade and WD_BLACK SN850X both crush it on sequential speeds and come with DRAM, often for similar money. The Crucial T710 is another strong option if you want raw performance. But here's the thing: none of those drives match the 990 EVO's power efficiency. If you're building a desktop and want maximum speed, get the SN850X or Fury Renegade. If you're upgrading a laptop or want a cool, quiet drive that sips power, the 990 EVO is actually the smarter pick. The Corsair MP700 Elite is also worth a look if you have a PCIe 5.0 slot and want to future-proof, but it'll cost you more.

Pricing is all over the place right now. We're seeing USD 170 to USD 449 across five US listings, which is a massive spread. At the low end, this is a steal for a 2TB Samsung drive with this endurance rating. At the high end, you're getting fleeced. The best deal in our database is at the USD 170 mark, and honestly, that's the only price where this drive makes total sense. If you're seeing it above USD 250, stop and look at the 990 EVO PLUS or a DRAM-equipped competitor instead.

The Samsung 990 EVO is a weird little drive. It's DRAM-less, which usually makes us nervous, but Samsung's HMB implementation and that in-house controller keep it feeling snappy in real-world use. The headline here is efficiency: Samsung claims up to 70% better performance per watt than the 970 EVO Plus, and for laptop users that's a genuinely big deal. You get 5,000 MB/s reads and 4,200 MB/s writes, which isn't going to top any charts, but it's plenty for gaming and general storage. The 2TB capacity and 1200 TBW endurance rating mean this thing should outlive most of the PCs it gets installed in.

If you're building a high-end desktop and want maximum sequential speeds, this isn't your drive. The WD_BLACK SN850X and Kingston Fury Renegade both offer significantly faster reads and writes with DRAM for similar money. And if you're doing heavy sustained workloads like 4K video editing or large file transfers all day, the DRAM-less design will eventually show its limits. Go get a DRAM-equipped drive instead.

The 990 EVO is a good drive that's often priced like a great one. At USD 170 for 2TB, it's an easy recommendation for laptop users, budget builders, and anyone who values efficiency over raw speed. At higher prices, the value proposition falls apart fast. The DRAM-less design isn't a dealbreaker thanks to Samsung's HMB implementation, but it does mean this drive isn't the best choice for heavy sustained workloads. If you can find it cheap, buy it. If not, the 990 EVO PLUS or a DRAM-equipped competitor is the better move.
