Cheapest 500 GB 2.5" SATA SSD
An SSD is a solid-state drive — a storage device with no moving parts that keeps your files, programs, and operating system. A 2.5" SATA SSD uses the SATA interface in a 2.5-inch case, a size and connection found in many desktops, laptops, and network storage enclosures. Before buying, confirm your device has a compatible 2.5-inch bay and a SATA connection, since form factors and interfaces vary. Our catalog lists 96 devices this drive fits.

Before you buy
- Check the fit before anything else. Look up your device or motherboard by model, or use our catalog of 96 compatible devices — it covers boards like the ASUS PRIME B550-PLUS and the ASRock B550M Pro4, small-form-factor desktops such as the Dell OptiPlex 7010 Small Form Factor, and network enclosures like the Synology DS224+ and DS920+.
- Match the form factor and the interface, not just one of them. This drive is 2.5 inches and uses SATA. An M.2 drive can use SATA or NVMe, and M.2 slots don't accept a 2.5" drive without an adapter or a separate mounting point — check what your device actually provides.
- Think about capacity before you narrow your search. This page compares 500 GB, 1 TB, 2 TB, and 4 TB versions of the same 2.5" SATA SSD style, so you can weigh how much room your system, apps, and files really need.
Questions
Will a 2.5" SATA SSD fit my computer or NAS?
Fit depends on two things: a 2.5-inch mounting bay and a SATA data and power connection. Desktops, laptops, and drive enclosures differ in both, so check your device's manual or search for its model in our catalog — it covers 96 devices this drive fits, including the Dell OptiPlex 3000 Small Form Factor and the ASUS ROG STRIX B650E-F GAMING WIFI.
How fast is a 2.5" SATA SSD?
A 2.5" SATA SSD is limited by the SATA interface, so it won't reach the transfer speeds of drives that use NVMe over PCIe. For everyday work — booting up, opening applications, copying files — most people notice a big step up from a spinning hard drive. Exact speeds vary by drive and by workload, so compare the specifications of each model you're considering.
Should I buy a new or used SSD?
Used drives can be a good value, but SSD storage wears down as data is written to it. If you buy used, check the drive's health and write statistics with the manufacturer's tools where possible, and know the seller's return policy. Whether the drive is new or used, keep backups of anything you can't afford to lose.
Is 500 GB enough storage?
It depends on what you keep. Your operating system and applications take a share of the 500 GB, and the rest is yours for documents, photos, and other files. If you work with large video files or keep a large game library, the 1 TB, 2 TB, and 4 TB versions compared on this page may suit you better.
