The seven options in detail
WD_BLACK 2TB SN850P (WDBBYV0020BNC-WRSN)
The listing calls this an NVMe M.2 SSD that is officially licensed as a storage expansion for PS5 consoles, with a speed claim of up to 7,300MB/s and a heatsink included. The 2 TB capacity is the draw: it is enough room to keep a wide spread of large games installed without constant deleting. The title does not give physical dimensions, so check the listing for heatsink height and width and compare them with Sony’s published limits. Because the 1 TB and 2 TB versions share a product line, the choice is about capacity and budget rather than design, and the 2 TB size also leaves headroom for patches, which can temporarily need extra free space during updates.
Pros
- Listed as officially licensed for PS5 consoles.
- Rated speed claim sits comfortably above Sony’s 5,500 MB/s recommendation.
- Heatsink is included, so there is no separate cooling purchase.
Cons
- Speed figures are a seller claim, and real-world results vary by console and workload.
- Heatsink dimensions are not stated in the title.
Who it’s for: players with a large installed library who want the licensed label. Who should skip it: anyone who plays only two or three games at a time, since 1 TB covers that for less.
WD_BLACK 1TB SN850P (WDBBYV0010BNC-WRSN)
This is the same SN850P family and the same licensed PS5 wording as the 2 TB model, only at half the capacity. The title again mentions up to 7,300MB/s and a bundled heatsink. For many households, 1 TB is the practical middle: it adds a large block of space beyond the console’s built-in storage, and it fits a rotation approach where finished games are removed and re-downloaded later. Treat the two WD_BLACK listings as variants of one product line. The model number in the title ends in a different capacity code, so make sure the one in your cart matches the size you meant to buy, because both listings look nearly identical at a glance.
Pros
- Licensed label and heatsink in the same package.
- Speed claim is above Sony’s recommended minimum.
- Capacity suits a rotating library.
Cons
- A few big modern titles can fill a 1 TB drive faster than expected.
- Check the listing for dimensions before ordering.
Who it’s for: most owners adding space for the first time. Who should skip it: collectors who keep dozens of games installed.
fanxiang 2TB NVMe Internal Gaming SSD with Heatsink
The title pairs a 2 TB capacity with a PCIe Gen 4 interface, a speed claim of up to 7100MB/s, a heatsink, and the phrase “compatible with PS5”. It does not say the drive is officially licensed, so it belongs in the unlicensed-listing group: the maker, rather than Sony, stands behind the compatibility claim. The title also targets gamers, professionals and creators, which hints that the drive is meant to work outside the console too, but nothing in the title confirms that, so verify it on the listing. If the maker’s warranty terms matter to you, read them before ordering, since an unlicensed drive depends on the manufacturer for any replacement.
Pros
- Large 2 TB capacity with a heatsink included.
- Speed claim clears Sony’s recommended 5,500 MB/s.
Cons
- No licensed label in the title.
- Form factor length and heatsink height are not given, so check the listing.
Who it’s for: buyers who want 2 TB and are comfortable choosing an unlicensed listing. Who should skip it: anyone who wants the licensed label for peace of mind.
fanxiang 1TB NVMe Internal Gaming SSD with Heatsink
This is the smaller sibling of the 2 TB fanxiang listing and shares its wording: PCIe Gen 4, heatsink, “compatible with PS5”, and a slightly lower speed claim of up to 7000MB/s. Because the two are variants of one product line, the decision comes down to capacity rather than design. A 1 TB size is a sensible entry point because it can be swapped later; the console has just one expansion bay, so a larger replacement means moving data over. Pick this size if your budget is firm and you rarely keep more than a few large games installed together.
Pros
- Heatsink bundled with the drive.
- Rated claim of 7000MB/s is above Sony’s recommended minimum.
- Same family as the 2 TB model if you want to scale up later.
Cons
- Not described as officially licensed.
- Physical dimensions need checking on the listing.
Who it’s for: players who want a simple 1 TB internal upgrade. Who should skip it: buyers who insist on a licensed drive.
SIX NVMe M.2 SSD PCIe 4.0, 1TB
The title for this one is the most explicit about format: PCIe 4.0 x4, M.2 2280, a read claim of up to 7350MB/s, a heatsink, and a pitch aimed at PS5 owners plus laptop and desktop users. Quoting the title, it is “Gen 4×4 NVMe”, which matches the interface Sony asks for. The dual-use positioning is the main differentiator; if you later upgrade the console to a larger drive, this one could move to a PC. Whether the bundled heatsink suits a PC board is something to confirm separately, since PC motherboards often come with their own heatsinks. The title also lists a laptop use, where a tall heatsink often cannot fit, so the bundled cooler is a console-first feature here.
Pros
- Title states M.2 2280 and PCIe Gen 4 x4.
- Highest read claim in this group at 7350MB/s.
- Can be repurposed in a desktop or laptop.
Cons
- No officially licensed wording in the title.
- The heatsink may not suit every PC board, so check clearance if you move it.
Who it’s for: buyers who want flexibility between console and PC. Who should skip it: anyone who wants the licensed label.
fanxiang S660 PCIe 4.0 1TB with Heatsink
This listing is the odd one out. It uses a PCIe 4.0 NVMe M.2 interface and includes a heatsink and an SLC cache, but the speed claim is “up to 5000MB/s”, which is below the 5,500 MB/s Sony recommends. The drive may still work in the console, since the recommendation is about performance rather than a hard block, but it falls short of the published guidance on paper. Read the listing carefully, and compare it with the faster fanxiang models above before you decide the saving is worth it. The title also stresses technology enthusiasts and IT professionals, which signals a general-purpose drive rather than one built around console load times.
Pros
- PCIe 4.0 NVMe M.2 with heatsink included.
- Listing positions it for PS5 owners and technology enthusiasts.
Cons
- Speed claim is below Sony’s recommended 5,500 MB/s.
- Not described as officially licensed, and length is not stated in the title.
Who it’s for: budget-conscious buyers who accept a slower rating. Who should skip it: anyone who wants to stay at or above Sony’s guidance.
YOTUO 1TB External Hard Drive (USB 3.0 and USB-C)
This is not an M.2 SSD and it is not a PS5 internal expansion. The title describes a portable hard drive with USB 3.0 and USB-C connections and names PS4, Xbox One and Xbox 360 among its supported devices; it never names PS5. It is included as a labeled runner-up because it fills a different job: a USB extended-storage drive can play PS4 games directly and can hold PS5 games in storage, but PS5 games must be copied back to internal or M.2 storage before they can be played. Think of it as a shelf rather than a play area: useful for freeing internal space between sessions, with copying times set by the hard drive rather than by the console.
Pros
- Portable and plugs into a USB port, with no opening of the console.
- Works for PS4 games and for archiving PS5 games.
Cons
- Cannot be used to play PS5 games directly.
- A spinning hard drive loads more slowly than an NVMe SSD, and the title does not name PS5 support.
Who it’s for: owners with a PS4 backlog or a need to archive games. Who should skip it: anyone expecting PS5 load speeds or direct play of PS5 titles.
How we picked these
The list is built from published specifications, manufacturer documentation and buyer reviews, plus the details in each seller’s listing title. Nobody on the team used or measured these units. We kept six internal M.2 drives that name PCIe Gen 4 or a PS5 use, then added one external drive so the USB limits could be explained with a real listing. Where a title gives no dimensions or licensing wording, the entry says so rather than guessing, and speed figures are treated as seller claims throughout. Items are ordered by capacity and licensing status rather than by a score, because the title data does not support ranking drives against each other on performance, and nobody should read the order as a verdict on quality.
What to look for in PS5 expansion storage
Interface and form factor
The PS5 expansion bay needs an M.2 NVMe SSD using PCIe Gen4 x4. SATA M.2 drives and Gen3 NVMe drives do not meet the requirement. A Gen5 drive is physically similar and can work in the Gen4 slot, but it will run at Gen4 speeds, so paying extra for Gen5 gains nothing on this console. The size is usually written as four digits: 2280 means 22 mm wide and 80 mm long. Sony’s published range covers several lengths, but 2280 is the most common and the easiest to find.
Heatsink fit
Sony recommends a cooling solution on the drive, and many listings bundle one. The catch is room: Sony’s published limits for a drive with a heatsink have been roughly 25 mm wide, 11.25 mm tall and up to 110 mm long, and the bay is not generous. Confirm the current numbers on Sony’s support page, then compare them with the heatsink height on the listing. A heatsink that is a few millimeters too tall will keep the cover from closing. Also avoid fitting a second heatsink over a built-in one.
Read speed and capacity
Sony recommends a sequential read of 5,500 MB/s or faster and supports capacities from 250 GB to 8 TB. Every internal drive in this list claims at or above that figure except the fanxiang S660. Speed ratings are “up to” numbers, so treat them as ceilings. For capacity, remember that a “1 TB” label is about 931 GiB once converted, and the file system takes a little more. As an illustration: if 900 GB is usable and your typical games take 60 GB, you can keep about 15 installed. At 2 TB, roughly twice that.
Licensed versus unlicensed
“Officially licensed” in a listing, as with the WD_BLACK models, signals that the manufacturer is part of Sony’s licensing arrangement and may carry PlayStation branding. It does not mean the drive is faster. An unlicensed drive that meets the requirements for interface, size and cooling can work, but support and warranty sit with the maker. If a drive is not recognized, or your console model changes the clearance, an unlicensed purchase leaves you with fewer options.
External USB drives and their limits
USB extended storage behaves differently from an M.2 drive. It can run PS4 games directly and can store PS5 games, but a PS5 title has to be moved back to internal or M.2 storage to be played. Sony asks for a drive using SuperSpeed USB (5 Gbps) or faster. A hard drive is fine as an archive shelf, and an external SSD is quicker than a hard drive, yet neither replaces the internal expansion bay for playing PS5 games.
Pre-purchase fit checklist
| Check | What to confirm | If it fails |
|---|---|---|
| Interface | NVMe, PCIe Gen4 x4 | Do not buy; SATA and Gen3 do not qualify |
| Length | Listed size is on Sony’s supported list (2280 is common) | Pick another drive |
| Heatsink height and width | Within Sony’s published limits | Remove the heatsink only if the maker says it is detachable |
| Read speed | 5,500 MB/s or higher claimed | Expect a mismatch with Sony’s guidance |
| Capacity | Fits your game count after the formatting overhead | Step up one size |
| Warranty | Terms stated by the manufacturer | Check the listing |
Installation overview
The steps are the same for every internal drive, with small differences between console models. Power the console down fully (not rest mode), unplug it, remove the side cover, and unscrew the expansion bay cover. Move the screw and spacer to the notch that matches your drive length, insert the drive at an angle, press it flat and secure it. Touch a grounded metal surface first to discharge static. Close the covers, power on and follow the on-screen format prompt. Pair this with our separate PS5 SSD roundup for more drive options, and see internal SSDs for PC builds if you are shopping for a desktop instead.
Mistakes buyers make
- Buying a Gen3 or SATA M.2 drive. Both look similar, but neither meets the Gen4 x4 requirement. Look for “PCIe 4.0 x4” in the listing.
- Ignoring heatsink height. A drive that clears the length limit can still block the cover if the heatsink is too tall. Compare the listed height with Sony’s page.
- Stacking heatsinks. A built-in heatsink plus a second one add height and trap heat. Use one.
- Treating the licensed badge as a speed upgrade. It is a program label. Compare speed claims and warranty instead.
- Expecting an external drive to play PS5 games. USB storage holds PS5 titles but cannot run them.
- Buying too little capacity. A 500 GB drive fills quickly when several games each take tens of gigabytes. If your budget stretches, consider the next size up, because replacing a full drive later means moving everything across.
- Skipping the update after install. Follow the on-screen prompts after formatting, and keep the console on a stable power source during any system update.
Verdict
For most owners, a 1 TB drive with a PCIe Gen4 x4 interface and a heatsink is the sweet spot, and the WD_BLACK 1TB SN850P is the safest choice if you want the officially licensed label. Pick the 2 TB WD_BLACK for a big library. The fanxiang 1TB and 2TB listings suit buyers who accept an unlicensed listing, and the SIX drive is the flexible option for PC reuse. Skip the S660 unless its lower rated speed is acceptable to you, and re-check heatsink dimensions on whichever listing you choose, and treat the YOTUO as an archive or PS4 drive only.

Frequently asked questions
What kind of SSD does the PS5 accept for internal storage expansion?
The expansion bay takes an M.2 NVMe SSD that uses PCIe Gen4 x4. Sony publishes a recommended sequential read speed of 5,500 MB/s or faster, a capacity range of 250 GB to 8 TB, and size limits that matter most when a heatsink is fitted. Gen3 drives and SATA M.2 drives do not meet the requirement. Always compare the drive’s dimensions with Sony’s current support page before buying.
Do I need a heatsink on a PS5 SSD?
Sony’s guidance calls for a cooling solution on the expansion drive, either a heatsink bundled with the drive or one added separately. A drive that ships with a heatsink saves a step, but the heatsink must still fit inside the bay, so check its stated height and width. Do not stack a second heatsink on top of one that is already attached.
Does an officially licensed SSD perform better than an unlicensed one?
Not automatically. Licensed means the manufacturer participates in a Sony-approved program and may carry PlayStation branding; it is not a speed guarantee. An unlicensed drive that meets the published requirements can work, but the maker, not Sony, stands behind it. Compare speed rating, heatsink fit, warranty terms and capacity rather than treating the badge as a performance upgrade.
Can I play PS5 games from an external USB drive?
No. An external USB drive can store PS5 games, but they must be copied back to the console’s internal storage or to the M.2 expansion drive before they can be played. PS4 games, however, can be played directly from a supported USB extended-storage drive. That makes a drive like the YOTUO listing useful for archives and PS4 libraries, not as a substitute for an internal M.2 SSD.
How much capacity should I buy for PS5 storage expansion?
Many large modern games take tens of gigabytes each and some pass 100 GB, so a 1 TB drive holds roughly a dozen or so big titles once system overhead is subtracted, while 2 TB roughly doubles that. If you play a rotating handful of games, 1 TB is workable. If you keep many installed at once, or save captures locally, 2 TB prevents constant deleting and re-downloading.
