Samsung 870 EVO

The 870 EVO 2TB maxes out SATA III at 560 MB/s read and 530 MB/s write, but its real superpower is endurance: 2,400 TBW and a 5-year warranty put it in the 95th percentile. With a 4.9/5 rating from 1,061 reviews, it's the most trusted SATA SSD on the market. Just don't expect NVMe speeds, and shop around because prices swing from USD 450 to USD 719.

Let's talk numbers. The 870 EVO maxes out the SATA III interface at 560 MB/s sequential read and 530 MB/s write. That's the ceiling, folks. No SATA drive can go faster, and Samsung's MKX controller with TLC NAND and DRAM cache keeps it pinned there. The Intelligent TurboWrite buffer helps sustain those write speeds longer, which matters when you're moving big files around. Random performance is 98K read IOPS and 88K write IOPS. In our database, that's a 37th percentile speed score and 41st percentile random score. Translation: it's fine for booting Windows, loading games, and general productivity, but it's not going to impress anyone who's used to Gen 4 NVMe speeds.

The 2TB capacity puts it in the 78th percentile for storage space, which is plenty for most people. And the endurance story is genuinely impressive. 2,400 TBW means you could write 1.3TB every single day for five years and still be within warranty. The 1.5 million hour MTBF is another data point that screams longevity. Samsung clearly built this drive to be boring in the best way possible.

Stacked against the Western Digital Black SN850X, Micron T710, Seagate FireCuda 530R, Kingston Fury Renegade, and Crucial T710, the 870 EVO is the tortoise in a field of hares. All five competitors are PCIe Gen 4 NVMe drives that absolutely demolish the 870 EVO on speed. The SN850X and FireCuda 530R push sequential reads past 7,000 MB/s, more than 12 times faster than the 870 EVO's 560 MB/s. The Micron T710 and Crucial T710 are essentially the same drive, and the Kingston Fury Renegade 4TB doubles the capacity. But here's the thing: none of those drives fit in a 2.5-inch SATA bay. If you're upgrading an older system, a NAS, or a video recorder, the 870 EVO is the only one of the bunch that actually works. And its 2,400 TBW endurance beats several of those NVMe drives on paper. It's not a fair fight on speed, but on compatibility and longevity, the 870 EVO holds its own.

Pricing on the 870 EVO 2TB is all over the place. In the US, we're seeing listings from USD 450 to USD 719 across 9 vendors. That's a USD 269 spread for the exact same drive, which is frankly ridiculous. The best deal is at the low end, USD 450, and if you're paying anywhere near USD 719 you're getting taken for a ride. In Canada, the spread is tighter but still notable: CAD 925 to CAD 1,062 across 4 listings. The CAD 925 price is the one to hunt for. For a SATA drive in 2025, even USD 450 feels steep when you can get a 2TB NVMe Gen 4 drive for less. But you're paying for the endurance, the warranty, and Samsung's track record. If you need SATA specifically, the 870 EVO earns its premium. Just don't overpay.

The Samsung 870 EVO 2TB is the SATA SSD that refuses to die, and honestly, we're glad. It hits the SATA III ceiling at 560 MB/s read and 530 MB/s write, which is about as fast as this interface gets. But the real story here is endurance: 2,400 TBW backed by a 5-year warranty. That's a 95th percentile endurance score in our database, meaning this drive will likely outlive the laptop you put it in. Social proof is off the charts too, 100th percentile with a 4.9 rating across 1,061 reviews. People love this thing.

Now, the catch. SATA is old tech. The random read IOPS sit at 98K and random write at 88K, which lands in the 41st percentile for random performance. That's solidly middle of the pack, and it's a reminder that any modern NVMe drive will run circles around this in real-world snappiness. But if you're upgrading an older desktop or laptop with a 2.5-inch bay, or you need a reliable drive for a NAS or video recorder, the 870 EVO is still the default answer.

Skip the 870 EVO if your system has an M.2 slot. The 37th percentile speed score and 41st percentile random performance mean any budget NVMe drive will feel dramatically snappier for the same or less money. The Western Digital Black SN850X, Micron T710, and Crucial T710 all deliver more than 10 times the sequential read speed. Also skip it if you're on a tight budget and don't need the endurance headroom. A cheaper SATA SSD with a lower TBW rating will handle everyday computing just fine. The 870 EVO's premium is for people who need the reliability, not the speed.

The Samsung 870 EVO 2TB is the best SATA SSD you can buy, and that's both a compliment and a caveat. The 2,400 TBW endurance, 5-year warranty, and 4.9-star rating from over a thousand buyers tell you everything about its reliability. The 560/530 MB/s speeds tell you everything about its limits. If you have a 2.5-inch SATA slot that needs filling, this is the drive. If you have an M.2 slot available, buy an NVMe drive instead and don't look back. The 870 EVO is a legend, but it's a legend of a dying interface.
