Crucial 1TB SSD SATA III

The Crucial MX500 1TB is the best SATA SSD for breathing life into older machines. It maxes out the SATA III interface at 560 MB/s and backs it up with a 5-year warranty and stellar reliability. Just shop around, US prices swing from $158 to $399 for the same drive.

Sequential speeds hit 560 MB/s read and 510 MB/s write, which is the SATA III speed limit, so no complaints there. Random performance lands at 95K read IOPS and 90K write IOPS, which puts it at the 44th percentile in our database. That's about average for SATA drives, but it's a far cry from what NVMe drives are doing these days. The speed percentile overall sits at 35th, which sounds rough until you remember this is a SATA drive competing against NVMe monsters in our rankings. For what it is, it's fast. For what's available in 2025, it's a dinosaur. But a reliable dinosaur.

Stacked against the Samsung 990 PRO, WD Black SN850X, or Team Group MP44, the MX500 looks ancient on paper. Those NVMe drives push 7,000 MB/s or more, while the MX500 is stuck at 560 MB/s. But that's not really the point. The MX500 exists for machines that can't take an NVMe drive, older laptops, budget builds, or anyone who just needs a reliable SATA SSD without fuss. The Lexar NM1090 and XPG Gammix S70 Blade are in a completely different league performance-wise, but they're also overkill for a 2015 Dell that just needs to boot Windows faster. Different tools for different jobs.

Pricing is all over the place right now. US listings range from $158 to $399, which is a $241 spread for the exact same drive. That's wild. If you're shopping in the US, the lower end of that range is a genuinely good deal for a 1TB SATA SSD with this kind of track record. The affordability percentile sits at 26th, which means it's pricier than most drives in its class, but you're paying for the reliability reputation and that 5-year warranty. Just don't pay $399. That's NVMe territory and you'd be getting ripped off.

The Crucial MX500 is the SATA SSD that refuses to die, and honestly, that's a good thing. It's a 2.5-inch drive that tops out around 560 MB/s read and 510 MB/s write, which is basically the ceiling for SATA III. If you're still rocking an older laptop or desktop with a spinning hard drive, this is the upgrade that makes it feel like a new machine. Boot times drop to seconds, apps snap open, and you get 1TB of TLC NAND with a 5-year warranty to back it up.

Now, the spec sheet says DRAM-less, which is a bit odd for the MX500 line. The endurance rating of 360 TBW is solid for a budget drive, and the 1.8 million hour MTBF sounds impressive until you realize that's just how these numbers work. The real story here is that 111,641 customer reviews average out to 4.8 stars. People love this thing.

If you have an M.2 slot available on your motherboard, skip this and get an NVMe drive instead. You'll get dramatically better performance for similar or less money. Also skip it if you're building a new PC in 2025, SATA is a dead end for new builds. And if you need a drive for heavy sustained writes or professional video editing, the random performance and SATA bottleneck will frustrate you.

If you've got an older machine with a 2.5-inch drive bay and you're still booting from a hard drive, buy this. It's the most reliable SATA SSD you can get without spending silly money, and the 5-year warranty means Crucial stands behind it. The 4.8-star rating from over 111,000 reviews isn't an accident. Just be ready to skip the bundled Acronis software and use something else for cloning, and don't expect any cables or brackets in the box.
