The Best SSDs Under $300

From the P310 1TB to the SN5100 2TB: five SSDs ranked on rated read speed and rated write speed, with who should skip each one.

By The PC Journal editorial team

12 min read5 products evaluated

Between $150 and $300, you can buy 4TB Gen4 drives or fast Gen5 models. Every pick sits in that range, ordered by read speed.

We sorted these picks by sequential read, sequential write and interface, working from the makers' own data; nothing here was tested in-house, and if a maker skips sequential write, the guide says so.

Samsung 990 PRO 1TB

Fastest Rated Read Speed1 of 5

Samsung 990 PRO 1TB on Amazon (opens in a new tab)

The 990 PRO 1TB offers 7,450MB/s reads and 6,900MB/s writes, the top rated speeds among the 1TB Gen4 drives here.

Best for

Buyers who put rated read speed first.

Skip if

Skip it if price comes first: the P310 1TB cost less when we checked.

Why we like it

Its random read and write are 40% and 55% faster than the 980 PRO, and Samsung's nickel-coated controller manages heat in slim laptops too. Nothing else here matches its 7,450MB/s rated read speed; the NM790 1TB comes closest at 7,400MB/s. On rated write speed it leads this guide at 6,900MB/s, ahead of the NM790 1TB (6,500MB/s).

You also get Samsung Magician software for firmware updates. It is an M.2 2280 drive, the standard length on desktop boards; check which of your board's slots it goes in, as some share lanes with SATA ports. It runs at full speed in any PCIe 4.0 M.2 slot and still works, slower, in a PCIe 3.0 slot. On price it sat fourth of 5, between the cheaper 990 EVO Plus 1TB and the pricier SN5100 2TB, at the time of writing.

How We Chose These SSDs Under $300

Each pick was assessed across 4 criteria weighted for real-world use.

Endurance
We noted TBW ratings and warranty length where listed.
Design
We checked interface, DRAM cache and heatsink options.
Capacity
We compared drives at the same capacity within each guide.
Speed
We compared rated sequential read and write speeds.

What to Look for in an SSD Under $300

Key buying criteria so you get the right fit the first time.

  1. How much rated write speed you need

    Among these picks, rated write speed runs from 6,000MB/s on the P310 1TB to 6,900MB/s on the 990 PRO 1TB. Pick the lowest figure that covers your use; the extra usually costs more than it returns.

  2. PCIe 4.0 is enough for games

    Game load times barely change between fast PCIe 4.0 and PCIe 5.0 drives. PCIe 5.0 helps large file copies and creative work.

  3. DRAM cache helps heavy use

    Drives with DRAM cache hold speed better under long writes. DRAM-less drives with HMB are fine for games.

  4. Cool the drive

    Fast drives throttle when hot. Use the motherboard's M.2 heatsink or a heatsink version of the drive.

  5. Buy more capacity than you think

    Many new games need 100GB or more. 2TB is a comfortable minimum for a gaming library; 4TB avoids juggling installs.

Which is the cheapest pick in this guide?

The P310 1TB cost the least when we checked, and the SN5100 2TB sat at the top of the range. Prices move often, so check the current listing before buying.

How much storage do I need for games?

2TB suits most players; 4TB suits large libraries without uninstalling.

Do I need an SSD heatsink?

Use one on fast drives. Most boards include M.2 heatsinks; otherwise buy the heatsink version.

Can I use these in a PS5?

PCIe 4.0 M.2 drives work in a PS5 with a heatsink that fits the bay. Check Sony's size limits.

Bottom Line

Our first pick is the 990 PRO 1TB, chosen for the fastest rated read speed here (7,450MB/s). Look at the NM790 1TB for a 1,000TBW endurance rating on the 1TB model, the 990 EVO Plus 1TB for a design that runs on PCIe 4.0 x4 or PCIe 5.0 x2 lanes and the P310 1TB for the cheapest way into this group, below the NM790 1TB if those matter more to you.

Pick capacity first; the speed difference matters less day to day.
