The PlayStation 5 shipped with a 667GB or 825GB internal drive, and after the operating system claims its slice, you’re realistically working with under 700GB of usable storage. Call of Duty alone can eat 200GB or more, and a handful of AAA installs will fill the console in a weekend. Sony’s expansion slot fixes that — an M.2 2280 NVMe SSD with a PCIe Gen4 interface and a heatsink turns your PS5 into a genuine game library — but the market is crowded with drives that range from $450 to well over $1,000 at list price, and not all of them are worth the slot.
This roundup ranks eight drives worth considering in 2026. One honest note up front: the prices below are current list prices, and at 4TB capacity many of these drives sit well above our $300 target at retail. The sweet spot for actually landing under $300 is watching major sale events, where 4TB Gen4 drives routinely drop 30-50 percent. We’ve ranked on real-world value, PS5 compatibility, thermal design, and how often each drive actually hits that sub-$300 window.

How We Picked
Every drive here meets Sony’s baseline requirements: M.2 2280 form factor, PCIe Gen4 interface, sequential read speeds of 5,500MB/s or faster, and a heatsink either pre-installed or bundled. We weighted four factors. First, sustained performance — the PS5 doesn’t need flagship PCIe 5.0 speeds, so paying extra for headline numbers above roughly 7,300MB/s buys you almost nothing in-game. Second, thermal design; a drive that throttles inside the console’s cramped expansion bay will stutter during long install sessions. Third, brand track record, because a game library lives on this drive for years. Fourth, price-to-terabyte value, including how aggressively each model is discounted during major retail events — that’s where the realistic path to under $300 lives for most 4TB drives. We did not conduct our own benchmark lab testing for this roundup; specifications are manufacturer-published figures.
The 8 Best Picks
1. WD_BLACK SN850X 4TB with Heatsink — Best Overall Performance
The SN850X is the benchmark the rest of this list chases. It’s an M.2 2280 drive rated up to 7,300MB/s read and 6,300MB/s write, with the pre-mounted heatsink sized to fit Sony’s expansion bay without blocking the slot cover. It’s the drive most PS5 owners should buy if budget is secondary to performance and longevity.
- Rated up to 7,300MB/s read and 6,300MB/s write
- Heatsink comes pre-installed — no fiddly thermal pad work
The con: at $769.99 list, it’s one of the most expensive options here. Skip it if you’re genuinely locked to a sub-$300 budget — wait for a steep sale or drop to 2TB instead.
2. Crucial P310 4TB with Heatsink — Best Brand Reliability
Crucial is Micron’s consumer brand, meaning the NAND inside is made by one of the world’s largest memory manufacturers. The P310 is marketed specifically for the PS5, rated up to 7,100MB/s, and ships with a heatsink already attached, in the standard 2280 length.
- Up to 7,100MB/s sequential read — comfortably above Sony’s spec
- Heatsink included and PS5-specifically marketed
At $548.99 list it’s not cheap, and its sustained-write reputation trails the SN850X for heavy file transfers. Skip it if you want maximum raw speed for content creation work on a PC as well.
3. Lufasnd 4TB Gen4 — Best Value When Discounted
Lufasnd is a lesser-known brand, but this 4TB M.2 2280 PCIe Gen4 drive advertises up to 7,300MB/s and PS5 expansion compatibility at the lowest list price on this list. For buyers watching for a sub-$300 window, a generic drive like this is the category most likely to cross that line during sales.
- 7,300MB/s rated read speed at the lowest list price here
- Full 4TB capacity aimed directly at PS5 expansion
The obvious con is brand track record — warranty support and long-term reliability data are thin compared to Western Digital or Crucial. Skip it if you keep irreplaceable data on your drive or want a name you can call when something goes wrong.
4. WD_BLACK SN850P 2TB Officially Licensed — Best Plug-and-Play Peace of Mind
This is the only drive on the list that’s officially licensed for PS5, and it shows: the heatsink is designed to clear Sony’s expansion cover with zero adjustment. Rated up to 7,300MB/s, it’s the SN850X’s philosophy in an officially sanctioned package.
- Officially licensed for PS5 — guaranteed physical fit
- 7,300MB/s rated read speed with integrated heatsink
Two catches: it’s 2TB, not 4TB, and at $394 list it’s not cheap per terabyte. Skip it if your whole point is a massive 4TB library — but note it’s the easiest way to get a premium WD drive at the lowest WD price here.
5. fanxiang S880E 4TB — Best High-Capacity Budget Option
The fanxiang S880E targets gamers directly: 4TB, PCIe Gen4, up to 7,000MB/s read, M.2 2280, and explicit PS5 storage-expansion compatibility, marketed to creators and professionals as well. It competes with the Crucial on capacity-for-dollar rather than brand cachet.
- 4TB capacity with 7,000MB/s rated read speed
- Positioned for both PS5 and desktop creative workloads
At $549.99 list it’s a hair above the Crucial while carrying less brand recognition, and the listing doesn’t specify a pre-installed heatsink, so check the bundle before buying. Skip it if heatsink inclusion is a must-have out of the box.
6. WD_BLACK SN7100 4TB — Best Dual-Purpose Drive
The SN7100 is Western Digital’s newer Gen4 drive, rated up to 7,000MB/s read and 6,700MB/s write on next-gen TLC 3D NAND, aimed at laptops and handheld gaming devices. Its higher write rating makes it arguably a better all-rounder than the SN850X for people splitting time between console and PC or a handheld.
- 6,700MB/s rated write speed — strong for large transfers
- 4TB on modern TLC 3D NAND for laptops and handhelds
It’s $579.99 list, and it’s designed for laptops and handhelds rather than the PS5 specifically — verify heatsink compatibility with your console before ordering. Skip it if you want a drop-in, heatsink-included console upgrade.
7. Sandisk Optimus GX PRO 850P 4TB — Best for Enthusiasts
The Sandisk Optimus GX PRO 850P is the premium play: a 4TB NVMe M.2 2280 drive built and marketed for PS5 consoles from the Sandisk brand that now sits under the same corporate roof as WD. It’s aimed at enthusiasts who want top-tier components and aren’t price-sensitive.
- Purpose-marketed for PS5 consoles in M.2 2280 format
- Premium Sandisk branding and component tier
At $1,139.99 list, it costs more than a second PS5, and the PS5 can’t use performance beyond roughly 7,300MB/s anyway. Skip it unless the money genuinely doesn’t matter — almost every other drive here does the console-identical job for hundreds less.
8. Bestoss 4TB with Heatsink — Best Headline Speed per Dollar
Bestoss advertises the fastest number on this list — up to 7,350MB/s read — on a 4TB PCIe 4.0 M.2 drive with a heatsink included, explicitly positioned as PS5 storage. Like Lufasnd, it’s a value brand riding the sweet spot of PS5 requirements.
- 7,350MB/s rated read — highest headline figure here
- Heatsink included for PS5 installation
At $610.98 list it’s oddly pricier than better-known budget rivals, and headline read speeds above 7,300MB/s deliver no real-world PS5 benefit. Skip it if you’d rather pay similar money for a Crucial or WD warranty.
Buying Guide
Meet Sony’s Minimums First
Your drive must be M.2 2280 size (80mm long), PCIe Gen4, and rated at least 5,500MB/s sequential read. Anything faster than roughly 7,300MB/s won’t improve PS5 load times, so don’t pay for PCIe 5.0. Sony also recommends a heatsink — the console’s expansion bay is a tight channel roughly the width of the drive itself, and bare drives can throttle. All-22mm-wide drives with tall cooling can block the M.2 slot cover screw; double-check height clearance.
Capacity and the Sub-$300 Reality
At 4TB, most name-brand Gen4 drives carry list prices between roughly $460 and $1,140, as this list shows. The reliable route under $300 is timing: 4TB Gen4 drives routinely see 40-50 percent discounts during major sale events. If you need storage now and can’t wait, a 2TB officially licensed drive at $394, or a 2TB name-brand drive on sale, often lands closer to target and still doubles your library.
Brand, Warranty, and Heatsinks
Big names — WD_BLACK, SanDisk, Crucial — offer multi-year warranties and predictable endurance ratings, which matter when your entire game library lives on one drive. Budget brands like Lufasnd, fanxiang, and Bestoss can save real money but check the stated warranty and TBW (terabytes written) rating before buying. Finally, prefer a drive with a pre-installed or bundled heatsink; aftermarket low-profile coolers work, but it’s one more purchase and fit risk.
Our Verdict
If money is no object, the WD_BLACK SN850X 4TB with heatsink remains the PS5 expansion drive to beat: 7,300MB/s rated reads, a proper pre-fit heatsink, and Western Digital’s track record. For most buyers, though, the smart play is the Crucial P310 4TB with heatsink if you find it discounted, or the Lufasnd 4TB if you’re patient enough to catch a genuine sub-$300 sale. PS5 owners who want zero guesswork should grab the officially licensed WD_BLACK SN850P — just accept the 2TB capacity. Avoid paying enthusiast prices like the $1,139.99 Optimus GX PRO unless the badge genuinely matters to you; the PS5 will never use the difference.
FAQ
Can the PS5 really use a 4TB NVMe SSD?
Yes. Sony’s expansion slot supports M.2 drives from 250GB up to 8TB, provided they meet the form factor (M.2 2280), interface (PCIe Gen4), and minimum sequential read speed (5,500MB/s) requirements. A 4TB drive with a heatsink installs in minutes via the expansion bay cover.
Do I need a heatsink for a PS5 SSD?
Sony strongly recommends one, and practically speaking, yes. The expansion bay is a narrow channel with limited airflow, and a heatsink prevents thermal throttling during large installs and transfers. Buy a drive with a pre-installed heatsink sized to fit the bay, and avoid coolers that make the drive too tall for the slot cover.
Will a faster SSD make PS5 games load quicker?
Not meaningfully beyond the baseline. The PS5 requires 5,500MB/s reads, and performance plateaus around the 7,300MB/s class of drives. Paying for drives rated faster than that — or for PCIe 5.0 models — yields no in-game benefit on this console.
How do I get a 4TB SSD for under $300?
Timing. Name-brand 4TB Gen4 drives regularly drop 30-50 percent during major retail sale events, which is when drives in the $460-$770 list range cross the $300 line. Set price alerts on the specific models above, and if you can’t wait, a discounted 2TB drive from a major brand is the safer sub-$300-adjacent purchase.
