Best PCIe 5.0 SSDs of 2026

Where our top pick is the safe default, the SN8100 is the drive for someone whose problem is size. This 4 TB version reads at up to 14,900 MB/s and writes at up to 14,000 MB/s — the highest read rating in this group — with over 2,300,000 IOPS and an average operating power of 7.5 W or under.

That power figure is the quietly important one. Gen5 drives have a reputation for turning a case into a space heater, and a drive averaging under 7.5 W isn't competing with your graphics card for airflow. Cooling is the least dramatic thing about this one, which is precisely what you want in a machine that runs all day, and capacities climb to 8 TB within the same family if 4 TB isn't enough.

We point editors, 3D artists, and anyone shuffling model weights at this drive, because 4 TB means fewer archive runs and the 14,000 MB/s write rating holds when you're exporting rather than just loading. Two cautions: it's the most expensive drive here, and the listing itself now directs shoppers to the SANDISK Optimus GX PRO 8100 as its replacement, so check which model name is in your cart before you commit.

DRAM cache plus a dynamic SLC cache is the pairing we look for in a Gen5 drive, because it's what keeps writes from sagging once the fast buffer fills up. The NM1090 PRO has both, along with a 6 nm controller and a 14,000/13,000 MB/s rating — and it sits at the bottom of the 2 TB price tier here, which is the part that made us look twice.

DirectStorage support matters if you play titles that use it, and 2 TB means you're not deleting a game to install the next one. Lexar rates it for AMD Ryzen and Intel i9 platforms and lists PS5 compatibility, though like every drive here it needs a heatsink inside the console. Fit it behind your board's own M.2 shield rather than placing a second order for a cooler.

The one place it gives ground is write speed: 13,000 MB/s against 14,000 on the drives above it. That gap shows up in large exports and big installs, not in game loads or boot times, so it's a fair trade for the money. Add the five-year warranty and this is the 2 TB drive we suggest when the budget has a ceiling.

Open the box and there's the drive, a heatsink, and a screwdriver kit. That sounds like filler until you're the person mounting a bare M.2 on a board with no shield, or filling an empty bay in a console at 9 p.m. The X15000 itself is rated at 14,356/13,662 MB/s with 2,000K/2,000K IOPS, a 6 nm controller, and 3D TLC NAND.

For a console or a first build, the bundle is the whole argument: the cooler is in the box, the screws are in the box, and there's no second order halfway through an install. In a PS5's Gen4 slot the speed advantage flattens out anyway, so what you're really buying is capacity, cooling, and a straightforward fit — and this drive delivers all three.

Before you order, one fit check: if your console is a PS5 Slim, confirm clearance in the bay, because the standard console is the safer fit. Otherwise this is the drive we hand to someone who wants to install once and stop thinking about it, and the screwdriver in the box tells you who SIX expects its buyers to be.

The GM9's title claims up to 14,500 MB/s; the specification table further down the page says 14,000 MB/s read and 11,000 MB/s write. Plan around the second set of numbers — and even at 14,000, that's a full-speed Gen5 read in a 1 TB drive, a size that usually gets a slower, cut-down design.

That's why it earns a spot: a 1 TB boot drive with Gen5-class reads, NVMe 2.0, DirectStorage support, and a 4.5 g stick that disappears into a laptop or a small-form-factor build. Use it for Windows and the games you're playing right now rather than as a library, and keep the board's M.2 shield on it.

What you give up is straightforward: this is a boot-and-working-set drive, not an archive. Put the operating system, your apps, and a couple of big titles on it, keep the rest on a SATA or Gen4 drive, and the terabyte goes a long way. Nothing else here reaches 14 GB/s reads for less.

Not everyone needs 14 GB/s. If you're moving up from a Gen4 build, or your board has a single Gen5 slot and the money is better spent elsewhere, the P510 is the drive that makes sense: 11,000 MB/s read, 8,500 MB/s write, and backward compatibility with Gen4 systems.

That backward compatibility is the useful part. Drop it into a Gen4 slot today and it runs at Gen4 speed; move it to a Gen5 board later and it climbs. The G8 NAND and thermal control come from the same engineering generation as Crucial's flagship drives, and the five-year warranty is the same.

Where it wins is the total picture: it asks less of your cooling than the 14 GB/s drives here, and it costs less than they do. If you game, browse, and write the occasional document, the difference won't show up in your day. If you export video for a living, it will — and that's the line between this drive and the ones above it.

An SM2508 controller built on a 6 nm process, low-power DDR4 cache, a buck converter for steadier voltage, and a 12-layer PCB: Kingston's parts list for the Renegade G5 reads like a set of answers to Gen5's two persistent problems, heat and power draw. The numbers are flagship-grade too — 14,700 MB/s read and 14,000 MB/s write on this 2 TB model.

Whether that engineering shows up in daily use depends on your case. A Gen5 drive that sits under a graphics card, in a compact build, or behind a mesh panel with modest airflow has less headroom than a bench does, and the efficiency work here is aimed squarely at that situation.

Performance isn't the question: 14,700 MB/s puts it in the same read class as our top pick, and 14,000 MB/s writes are at the top of this group. The 2 TB capacity covers a working project folder plus a game library, which is more than most people can say for a 1 TB boot drive.

The sticking point is money. It costs as much as our top pick, and the Samsung answers with its software suite while the Lexar answers with a lower price. Where the Kingston wins is the build philosophy: if your M.2 slot lives somewhere cramped and hot, this is the drive we point to, because it was designed for that slot rather than for a test bench.

The T710 is quick — 14,500 MB/s read, 13,800 MB/s write, with Micron's G9 TLC NAND underneath — but it's the drive here we hesitate over, and the hesitation has nothing to do with speed.

On paper it's a well-rounded 2 TB drive: a heatsink-compatible M.2 2280 design, tuning for Intel 13th and 14th gen and Ryzen 7000 boards, and thermal management that keeps it from throttling in ordinary use. It also ships with a month of Adobe Creative Cloud, which is a genuine extra if you're already paying for it.

The hesitation is durability, and it's why this card sits where it does rather than alongside our top picks. A drive that works fine and then stops is the worst kind of failure, because by then it's holding work you can't recreate, and the five-year warranty gets you a replacement rather than your files back.

If you want it anyway, buy from a seller with easy returns, keep a copy of anything you can't re-download, and treat the warranty as a safety net rather than a plan. Otherwise the Samsung, Lexar, and Kingston drives cover the same 2 TB ground with less to worry about.
