2.5" SATA SSD prices
A 2.5-inch SATA SSD is a solid-state drive in the familiar laptop-style case, wired to your device with SATA data and power cables. It's one of the easiest upgrades you can make: it replaces a slow hard drive, speeds up booting and file access, and runs silently. Before you buy, check three things — that your device has a 2.5-inch drive bay, that it offers a SATA interface, and that the drive is listed for your specific model.

Before you buy
- Match the form factor. These drives are 2.5 inches wide and 7 mm or 9.5 mm thick. Most current models are 7 mm and work in either slot, but if your bay, sled, or laptop caddy is tight, confirm the height first. Don't confuse a 2.5-inch SATA SSD with an M.2 or NVMe drive — they look and connect very differently.
- Don't shop by peak numbers alone. Every drive here is limited by the SATA interface, so real-world speed is similar across models. Capacity, warranty terms, and the vendor's rated endurance usually matter more to you than small spec-sheet differences.
- Buy the capacity you'll grow into. Drive prices rise with size, so it's worth thinking about what you'll store — an operating system and apps, a game library, media archives, or a NAS full of backups — before you compare the four sizes on this page.
Questions
Will a 2.5-inch SATA SSD fit my computer?
If your device has a 2.5-inch drive bay and a SATA connection, yes. Desktops usually mount the drive in a 2.5-inch slot or a drive sled; if your case only has 3.5-inch bays, a simple adapter bracket may be needed. Laptops must have a 2.5-inch SATA bay — slim ultrabooks often don't. NAS enclosures vary: some accept 2.5-inch drives directly, while others need a tray or bracket. Always check the bay size and the drive's thickness before ordering.
How fast is a 2.5-inch SATA SSD?
SATA is the bottleneck. The interface tops out around 550–560 MB/s, and most drives in this category come close to that ceiling, so you'll see little speed difference between them. Compared with a mechanical hard drive, everything feels quicker — starting up, opening apps, copying files. Compared with an NVMe SSD, sequential transfers are slower, though for everyday desktop work the gap is less noticeable than the numbers suggest.
Is a 2.5-inch SATA SSD compatible with my desktop, laptop, or NAS?
It's compatible with any device that provides a 2.5-inch bay and a SATA port. That covers a lot of desktops and older laptops, and many home and small-office NAS units. For NAS enclosures, the manufacturer may publish a list of tested drives — that's the safest thing to check. Our catalog shows 96 devices that accept this kind of drive, including boards and systems such as ASUS PRIME B550-PLUS, ASRock B550M Pro4, Dell OptiPlex 3080 Small Form Factor, Synology DS224+, and Synology DS920+.
Should I buy new or used, and how much capacity is enough?
A new drive gives you a full warranty and a known history, which is worth a lot in a device that stores your data. A used drive can be fine for scratch space or secondary storage, but you generally can't tell how much wear it has already absorbed. For capacity: 500 GB works as a basic system drive, 1 TB is comfortable for general use and a decent game or photo collection, 2 TB suits media libraries and heavier workloads, and 4 TB is for large archives or a NAS where you want one drive to hold everything.
