If you specifically need a 2.5-inch SATA SSD, my pick in 2026 is the Samsung 870 EVO.
$879.99
The MX500 is an excellent alternative if you find it substantially cheaper. It also uses TLC and has historically been one of the best SATA drives. However, Crucial has stopped making the MX500, so I'd favor the 870 EVO when prices are close.
$419.99
If you're just upgrading an old HDD and want lots of inexpensive storage, the BX500 can make sense. It's considerably cheaper, but it's a budget drive and can slow substantially during very long writes.
My ranking:
| Drive | Best for |
|---|---|
| 🥇 Samsung 870 EVO | Best overall / OS / gaming / heavy use |
| 🥈 Crucial MX500 | Value, if discounted |
| 🥉 Crucial BX500 | Cheapest bulk SATA storage |
One important caveat: If your PC supports NVMe M.2, don't buy a SATA SSD for a new build unless you have a specific reason. NVMe is substantially faster and is generally the better choice today.
If you tell me your capacity (1TB/2TB/4TB) and budget, I can search current prices and find the best deal rather than just the best drive.

When it comes to the 2.5-inch SATA III interface, the market has largely matured as focus has shifted to ultra-fast NVMe M.2 drives . However, two undisputed champions remain at the top for legacy system upgrades, secondary storage, and bulk capacity.[](https://www.youtube.com/watch?v=kuUunMC6qFg&t=522)[[2](https://www.pcmag.com/picks/the-best-ssds-for-gaming)](https://www.pcmag.com/picks/the-best-ssds-for-gaming)[[3](https://www.tomshardware.com/reviews/best-ssds,3891.html)](https://www.tomshardware.com/reviews/best-ssds,3891.html)
The two best options on the market depend on whether you want absolute peak performance or the best overall value:
Widely considered the gold standard for SATA drives, the Samsung 870 EVO maxes out the SATA 6Gbps interface boundaries (560 MB/s read, 530 MB/s write) and delivers record-setting mixed workload and 4K random read/write speeds. It features exceptional write endurance (up to 2,400 TBW on the 4TB model) and uses Samsung’s polished Magician software for drive management. It is slightly more expensive, but it's the most robust performer you can buy.
If the Samsung is priced a bit too high, the Crucial MX500 is the ultimate alternative . It offers near-identical real-world performance for everyday tasks like boot-ups and game loading, backed by a respectable 5-year warranty and hardware-based encryption. While its endurance specs and heavy sustained write speeds trail slightly behind the Samsung 870 EVO , it is routinely cheaper, making it the go-to value pick.[](https://www.reddit.com/r/buildapc/comments/uqp52l/crucial_mx500_vs_samsung_870_evo_1_tb_specs/)[[2](https://www.pcmag.com/picks/the-best-ssds-for-gaming)](https://www.tomshardware.com/reviews/best-ssds,3891.html)[[3](https://www.tomshardware.com/reviews/best-ssds,3891.html)](https://www.pcmag.com/picks/the-best-ssds-for-gaming)[[4](https://www.reddit.com/r/buildapc/comments/uqp52l)](]()]()

If you're looking for the highest-quality SATA SSDs, I'd prioritize long-term reliability, NAND quality, sustained write performance, endurance ratings, and warranty support over advertised sequential speeds alone. SATA III tops out at roughly 550 MB/s in real-world transfers, so the best drives tend to perform similarly in everyday use even when their internal hardware differs considerably.
For a premium 2.5-inch SATA SSD, I'd start with established models from Samsung, Crucial, and WD/SanDisk, while paying attention to whether a particular model or capacity has changed its underlying components.

Can you suggest the best SATA SSDs available right now?
(Best overall)
The drive I'd choose first for a premium SATA upgrade. It uses TLC NAND and a DRAM cache, reaches up to 560 MB/s read and 530 MB/s write, and has a five-year limited warranty. The 4TB model is rated for 2,400 TBW.
Capacities: 250GB–4TB · 2.5-inch SATA
(Excellent alternative)
A strong alternative with TLC NAND, DRAM, a five-year limited warranty, and useful data-integrity features. The 1TB version is rated for 360 TBW, and the 2TB version for 700 TBW.
Important: Crucial's production and availability situation has changed, so check stock carefully and avoid paying an inflated price for old inventory.
Capacities: 250GB–2TB in the documented range
(Premium alternative)
Worth considering if you want another established SATA drive with TLC NAND, DRAM, and hardware encryption support. It is a sensible alternative when the Samsung is unavailable or overpriced.
Capacity availability and price vary by market.
A candidate for NAS workloads and storage systems that perform frequent reads and writes. It is designed for NAS use, rather than being simply a budget drive for occasional desktop use. Compare its price and endurance rating against the 870 EVO before buying.
| Drive | NAND / cache | Best use |
|---|---|---|
| Samsung 870 EVO | TLC + DRAM | Premium general-purpose storage |
| Crucial MX500 | TLC + DRAM | Desktop or laptop upgrade |
| Kingston KC600 | TLC + DRAM | General use, including encryption |
| WD Red SA500 | NAS-oriented design | NAS and frequent storage access |
These are product-family-level comparisons; exact specifications and availability can vary by capacity and revision. The Samsung has the clearest case for the top spot based on documented specifications and current independent testing.
The Samsung 870 EVO is my first choice for a high-quality SATA SSD, particularly at 1TB or 2TB. However, don't pay a massive premium simply because it is a premium model. Current listings can be unusually expensive, and a drive's rated endurance is not a guarantee against failure. Keep independent backups of important data.
One final distinction: if your system accepts an M.2 NVMe SSD, rather than requiring SATA, a good NVMe drive is usually a better purchase for a new build. If you're replacing a 2.5-inch laptop hard drive or filling a SATA-only bay, the recommendations above are more relevant.
What capacity are you looking for — 1TB, 2TB, 4TB, or something larger? I can narrow this down to the best-quality models that are actually worth buying at today's prices.
Because major hardware manufacturers have largely shifted their R&D toward faster NVMe (PCIe) drives, the high-end 2.5-inch SATA SSD market has stabilized. The top-tier, highest-quality SATA drives available are well-established champions known for fully saturating the 600 MB/s SATA III interface limit [2.2], offering strong endurance (TBW), and featuring reliable DRAM caches.
