Quick verdict
Before comparing prices, check which format your machine takes: an M.2 NVMe SSD won't fit a computer that only has a 2.5-inch bay. That said, the 240 GB Patriot Burst is the best buy for reviving an old PC; the 128 GB Foresee is the cheapest entry; and the 480 GB Patriot if you want capacity not to run short.
What to look for before buying
- Format: 2.5-inch SATA or M.2 NVMe — It's the first thing and what causes most mistakes. The 2.5-inch SATA connects with two cables and fits any desktop and almost any laptop that once had a mechanical drive: it's the universal replacement. M.2 NVMe is a small board that screws straight onto the motherboard and is far faster, but your machine needs that slot. If you don't know what you have, open the machine and look, or search the exact model before buying.
- Real speed: SATA vs NVMe — A SATA SSD runs around 500 MB/s and an NVMe can exceed 2000 MB/s. That sounds enormous and for large file transfers it is. But for what most people do — booting, opening a browser, loading programs — the big jump already happened when you moved from mechanical to SSD. From there to NVMe the improvement is far less perceptible.
- Capacity: what you actually need — 120 or 128 GB just about covers the operating system and a few programs: you'll be managing space constantly. 240 GB is the comfortable minimum as your only drive. 480 GB or more is advisable if you keep photos, games or work files. A common cheap strategy: a small SSD for the system and the old mechanical drive as file storage.
- TLC memory and controller — Budget SSDs typically use TLC or QLC memory, which is cheaper but tolerates fewer write cycles than MLC. For normal home use the difference is theoretical: you'll replace the computer before wearing out the drive. Where it matters is if you'll write and erase enormous amounts of data daily, which doesn't happen in home use.
- Brand and warranty — On SSDs the brand matters more than on other components, because a failing drive takes your data with it. Kingston and Patriot are known brands with real local warranty. Generic or OEM units are considerably cheaper and usually work fine, but if they fail there's nobody to claim from. Whichever you pick, back up what matters: no drive lasts forever.

Swapping a mechanical drive for an SSD is, without argument, the best upgrade you can make to a computer. More than adding memory, more than changing the processor: a machine that took three minutes to boot is ready in fifteen seconds.
First: which format your machine takes
This is the part that generates the most returns.
- 2.5-inch SATA — connects with two cables, about the size of a cigarette packet. Fits any desktop and almost any laptop that once had a mechanical drive. It’s the universal replacement.
- M.2 NVMe — a thin board that screws straight onto the motherboard. Far faster, but your machine needs that slot.
If you don’t know which you have: open the machine and look, or search your exact laptop model together with “M.2” or “NVMe”.
Our pick
For most people the 240 GB Patriot Burst is the right buy: SATA format that fits everywhere, comfortable capacity as your only drive, and a brand with warranty. To spend the least, the 128 GB Foresee (if you have an M.2 slot) or the 120 GB Hiksemi in SATA. And if you want not to run short, the 480 GB Patriot.
On speed, honestly
An NVMe is four times faster than SATA on paper. But the jump you’ll actually feel already happened when you moved from mechanical to SSD. From SATA to NVMe the difference shows when moving very large files, not when booting or opening a browser. Don’t overpay for that figure if your use is normal.
The cheapest trick
If your PC has room for two drives: fit a small SSD for the system and keep the old mechanical drive as storage for photos and files. You get all the speed where it counts and give up not a single gigabyte.
And a warning that applies to any drive: back up what matters. None last forever, and SSDs fail without warning noises.

Frequently asked
How do I know whether my PC takes M.2 or 2.5-inch?
The safe way is to look. On a laptop, remove the bottom cover: if you see a rectangular drive about the size of a cigarette packet connected with two cables, that's a 2.5-inch bay. If you see a thin board resembling a small RAM stick screwed to the board, that's M.2. Many machines have both, in which case you can add an M.2 without removing the old drive. If you'd rather not open anything, search your exact model plus the words M.2 or NVMe: the manufacturer's spec sheet will say.
Is upgrading an old PC from a mechanical drive to an SSD worth it?
It's the best upgrade you can make to a computer, without question. Swapping a mechanical drive for an SSD makes more difference than doubling the RAM or changing the processor: a machine that took three minutes to boot is ready in fifteen seconds, and programs open instantly. It's the only upgrade that makes a seven or eight year old PC feel usable again, and for what a 240 GB SSD costs today it's money extremely well spent.
How much capacity do I need?
If it's your only drive, 240 GB is the comfortable minimum: Windows, the usual programs and some files fit, though you'll need to stay tidy. At 480 GB you work without thinking about it. The 120 or 128 GB units only make sense in two cases: as a system drive in a PC that also has a mechanical drive for storage, or in a very basic machine. That combination — small SSD for the system, old drive for files — is the cheapest way to speed up a PC without giving up space.
