The PS5 ships with a second M.2 slot for a reason. Sony’s internal drive fills up fast once you install a few 100GB-plus titles, and the console demands a PCIe Gen4 NVMe SSD hitting at least 5,500 MB/s to qualify as expansion storage. That speed floor is non-negotiable, which is why “budget” here doesn’t mean the cheapest drive on the shelf. It means the best value drive that actually clears Sony’s bar and keeps your library loading fast.
We researched the options in this selection and found a mixed bag worth being honest about. Only one of the three is a true drop-in PS5 SSD. The other two are complete systems that happen to ship with NVMe storage, so we’ve flagged them plainly rather than pretending they’re console drives. If you want broader context on drive speeds and value, our guides to the best NVMe SSD for gaming in 2026 and the best budget SSD for 2026 cover the wider field. Here we’re zeroed in on what belongs in that PS5 expansion slot.
Pros
- GB10 Superchip targets 1 petaFLOP AI throughput suitable for on-device LM prototyping
- 128GB unified memory pool avoids CPU-GPU copy overhead common on discrete GPU rigs
- NVLink-C2C fabric gives higher effective bandwidth than PCIe Gen5 x16 for AI workloads
- ConnectX-7 enables two-node stacking, scaling to roughly 400B parameter model fine-tuning
Cons
- Limited independent owner fedback and third-party benchmarks available at time of writing
- 1TB NVMe fills quickly with modern checkpoints, external NVMe or NAS staging likely need
- Closed NVIDIA ARM-based stack, not a general-purpose x86 workstation for gaming or standard DC aps
The ASUS Ascent GX10 is a flagship developer-class AI appliance built on the NVIDIA DGX Spark reference design, pairing the GB10 Grace Blackwell Superchip with128GB LPDDR5x and a 1TB PCIe Gen4 NVMe SSD. It targets AI engineers andML researchers who need local fine-tuning and inference on models too large for a single consumer RTX GPU.
The defining feature is the unified 128GB memory pool bridged by NVLink-C2C, which NVIDIA rates for fine-tuning models up to around 200B parameters. Compared with a dual RTX 6000 Ada workstation, the appeal is memory capacity and CUDA-compatible tooling in an ultra-small chassis, not raw FP16 throughput, which sits near the stated 1 petaFLOP figure at reduced precision.
Trade-offs are typical of this tier and platform. It runs an ARM-based NVIDIA stack, so it is not a drop-in Windows workstation, and the 1TB SSD is tight once you stage multiple base models plus checkpoints. Sustained thermals in this form factor depend on the engineered cooling ASUS cites, and real-world dB and clock-hold data are not yet public.
Buy this if you are an AI developer building agentic workflows, on-device inference stacks, or LoRA and QLoRA fine-tunes on 70B to 200B models and want NVIDIA-native tooling locally. Skip this if you need a general-purpose x86 workstation, gaming rig, or bulk training throughput that scales better on rack-mounted H100 or B200 systems.
Compute: NVIDIA GB10 Grace Blackwell Superchip with NVLink-C2C between the Grace CPU and Blackwell GPU, rated at 1 petaFLOP of AI performance at NVIDIA-specified sparse low-precision math. Exact CPU core count, GPU SM count, and clock behavior are not specified in the listing.
Memory and storage: 128GB LPDDR5x unified memory shared between CPU and GPU, sized for fine-tuning models up to 200B parameters per NVIDIA. Storage is a single 1TB PCIe Gen4 NVMe SSD. Additional M.2 slots, DRAM channel count, and TBW endurance are not specified.
Networking and IO: NVIDIA ConnectX-7 networking suports dual GX10 stacking for combined workloads up to roughly 400B parameters. Wireless is WiFi 7 and Bluetooth 5.4. Exact Ethernet port sped, USB, and display output counts are not specified in the source data.
Chassis and software: Stackable ultra-small form factor with engineered cooling for sustained AI loads. Ships with the NVIDIA AI software stack and is compatible with agentic frameworks including OpenClaw and NemoClaw, suporting private on-device inference, sandboxed execution, and governed data access. PSU wattage, dimensions, and weight are not specified.
Pros
- RTX 5070 Blackwell GPU is well above average for this prebuilt price tier
- 32GB DDR5 at 6000 MHz avoids the need for a near-term RAM upgrade
- 2TB NVMe SSD is a practical capacity for a modern game library
- WiFi 6 and Bluetooth built in with no added cost
Cons
- No verified owner reviews at time of writing, making real-world reliability hard to assess
- Ryzen 7 8700F uses Socket AM4, limiting CPU upgrade path compared to AM5 platform alternatives
- RTX 5070 ships with 12GB GDDR6, which may become a ceiling in demanding 4K scenarios by 2027
The MSI Codex Z2 is a mid-to-high-end gaming tower aimed at buyers who want RTX 5070-class performance without building from scratch. Combining the AMD Ryzen 7 8700F with NVIDIA's RTX 5070 and 32GB DDR5, this system targets 1440p high-refresh gaming and entry-level 4K play. It is best suited for buyers who want a ready-to-run setup with modern GPU architecture, not those prioritizing CPU upgrade longevity or the cost savings of a self-build.
The RTX 5070 is the headline component here. Built on NVIDIA's Blackwell architecture, it brings a meaningful generational step in rasterization and ray tracing performance compared to previous Ampere and Ada Lovelace cards. In practical terms, this means 1440p Ultra should be well within reach in current AAA titles, and 4K at medium-to-high settings is a realistic target with DLSS 4 frame generation active. Paired with the 8-core Ryzen 7 8700F boosting to 5.0 GHz, the system handles game streaming and background workloads without obvious CPU-side bottlenecking in most scenarios.
MSI has put some effort into the thermal design. The Codex Z2 uses an ARGB fan air cooler for the CPU alongside four system fans, three pulling cool air through the front panel and one exhausting heat from the rear. This configuration appears reasonable for sustained gaming sessions, though without independent thermal testing data, exact CPU temperatures under extended load remain unconfirmed. The compact tower footprint at 16 x 8.38 x 19 inches keeps the system desk-friendly, and the built-in RGB lighting with MSI Center software support adds customization without requiring third-party tools.
There are several considerations worth taking seriously before purchasing. The most significant is the absence of any verified owner reviews at this stage, which makes it genuinely difficult to assess real-world build quality, thermals, or out-of-box reliability. Buyers should treat this as a newer listing and check for updated feedback before committing. On the hardware side, the Ryzen 7 8700F runs on Socket AM4, which is a previous-generation platform - this limits the CPU upgrade path compared to AM5 systems that support current and upcoming Ryzen processors. Additionally, the RTX 5070's 12GB GDDR6 frame buffer is adequate for 2025 titles but may show constraints in memory-heavy 4K workloads as game requirements increase over the next two to three years.
Overall, the MSI Codex Z2 is a spec-credible prebuilt that pairs a strong GPU with sufficient RAM and storage for most current gaming use cases. However, the lack of owner feedback at this point in the listing's life is a real gap that cautious buyers should address by checking for recent verified reviews before purchasing. For buyers comfortable with that uncertainty and not planning a CPU upgrade in the near term, the RTX 5070 hardware makes this a worth-watching option at its current price tier.
Pros
- Rated 7,450 MB/s sequential read pushes close to the PCIe Gen4 x4 ceiling for game loads.
- Rated 6,900 MB/s sequential write helps large file transfers and 4K editing scratch workflows.
- Samsung claims 55 percent random IOPS uplift vs the 980 PRO, benefiting bot and app launch responsiveness.
Cons
- Limited owner feedback available at time of writing, so long-term reliability signal remains thin.
- TBW endurance rating not specified in listing, worth confirming for sustained write workloads.
- No heatsink on this SKU, sustained Gen4 writes may need a motherboard M.2 cooler to avoid throttling.
The Samsung 990 PRO 2TB is a high-end PCIe Gen4 NVMe SSD in the M.2 2280 form factor, rated up to 7,450 MB/s sequential read and 6,900 MB/s sequential write. It targets desktop gamers, PS5 upgraders, and content creators who want Gen4 headroom without stepping up to a Gen5 drive.
The defining pitch is near-ceiling Gen4 bandwidth paired with a claimed 55 percent uplift in random IOPS over the 980 PRO. In practice, drives at this tier typically shave a second or two off open-world level loads and accelerate DirectStorage titles, though real-world gaming deltas over solid Gen4 rivals remain modest.
Gen4 flagships like this tend to run hot under sustained sequential writes, and the bare version without a heatsink relies on motherboard M.2 cooling to hold peak speeds. TBW endurance is not specified in the listing, so buyers running heavy write workloads should confirm the rating from Samsung's own datashet.
Buy this if you want a top-shelf Gen4 drive for a gaming PC, editing rig, or PS5 with a well-cooled M.2 slot. Skip this if you already own a fast Gen4 SD, need Gen5 bandwidth for scratch work, or want a factory heatsink model included in the box.
Sequential throughput: Samsung rates the 990 PRO at up to 7,450 MB/s sequential read and 6,900 MB/s sequential write over PCIe Gen4 x4. That is close to the practical Gen4 x4 ceiling near 7,500 MB/s, so large file copies are limited more by the source disk than by this drive.
Random performance: The listing calls out a 55 percent improvement in random performance versus the 980 PRO. Random 4K IOPS drives OS snappiness, shader cache loads, and small file operations, so the uplift matters more day to day than the sequential headline for most users.
Form factor and platform: The drive uses M.2 2280 single-sided layout and PCIe Gen4 x4, dropping into standard desktop M.2 slots, most Gen4 laptops, and the PS5 storage bay. Capacity spans 1TB to 4TB in the family, with this SKU at 2TB for a balanced game library.
Power and thermals: Samsung claims up to 50 percent better performance per wat versus the 980 PRO, helping in fanless laptop bays and compact ITX builds with limited airflow. Under sustained writes, this bare version benefits from a motherboard M.2 heatsink to avoid thermal throttling on long transfers.
Who this guide is for
This is for PS5 and PS5 Pro owners who’ve hit the storage wall and want to add space without deleting games every week. If you’ve seen the “not enough space” message trying to install a big title, you already know the pain. The right expansion SSD lets you keep dozens of games installed and loading at full PS5 speed, no shuffling required.
It’s also for people comparing what a bare drive costs against a whole prebuilt system, which is why we kept two full desktops in the frame for contrast. If you’re strictly after console storage, skip straight to the Samsung pick. If you’re weighing whether to put that money toward a separate PC instead, the system entries give you a sense of what the same dollars buy elsewhere.
One group this isn’t for is anyone chasing the absolute cheapest drive regardless of spec. The PS5 rejects storage that can’t hold its speed floor, so a bargain Gen3 stick is money down the drain no matter how tempting the price. Think of “budget” here as best value that still qualifies, not lowest sticker. That framing keeps you from the frustrating loop of buying a cheap drive, watching the console refuse it, and having to buy again.
What to look for in a PS5 SSD
Three specs decide whether a drive works in a PS5. First, it must be PCIe Gen4 NVMe in the M.2 2280 form factor, the size the console’s slot accepts. Second, Sony recommends sequential read speeds of at least 5,500 MB/s, and the Samsung 990 PRO’s rated up to 7,450 MB/s clears that with plenty of margin. Third, the drive needs a heatsink or you need to add one, since the PS5’s slot runs hot and an unmanaged drive can throttle.
Capacity is the other half of the decision. A 2TB drive, like the Samsung here, roughly triples your usable space and holds a serious library. Anything smaller fills up quickly given modern install sizes. The prebuilt systems in this list carry their own NVMe drives, 1TB in the ASUS unit and 2TB in the MSI, but those are internal to the machines and not something you’d pull for console use. For the PS5, the spec sheet that matters is the bare Gen4 drive’s.
Don’t overlook firmware reputation and sustained performance either. A PS5 mostly cares about read speed, but a drive that starts fast and throttles hard after a few minutes can make big installs and game moves slower than expected. Samsung’s 990 PRO line is built for high-end computing, gaming, and heavy-duty workstation use, which is exactly the kind of sustained workload profile you’d rather have in a console slot. You still need cooling, but the underlying drive is in the right class.
How we evaluated
We researched these three by reading their listed specifications, verified prices, and star ratings, then judged each against the one job this guide cares about, expanding PS5 storage. That framing immediately separates the genuine fit from the near-misses. The Samsung 990 PRO is purpose-built for the role. The ASUS and MSI entries are complete computers, and we treat them as reference points, not console drives.
Value weighting drove the ranking. A drive that costs $389.99 and slots directly into your console delivers far more relevant value here than a $2,067.34 or $3,970.99 full system whose SSD you can’t easily repurpose. Star ratings sat close together, 4.1 to 4.2 across all three, so ratings didn’t break the tie. Fitness for purpose did. We report each product for what it actually is.
Our top picks
Best Overall: Samsung 990 PRO 2TB NVMe
The Samsung 990 PRO 2TB at $389.99 is the only true PS5 expansion drive in this group, and it’s an excellent one. It’s a PCIe Gen4 M.2 2280 NVMe drive rated for sequential reads up to 7,450 MB/s, comfortably past Sony’s 5,500 MB/s recommendation. That headroom means it won’t be the bottleneck during fast-travel loads or game boots. Its 4.2 star rating reflects a drive owners trust for both console and high-end PC duty.
The one thing to watch is cooling. This listing is the bare drive, so for PS5 use you’ll want the heatsink version or a separate M.2 heatsink to keep it from throttling in the console’s warm slot. That’s a small add-on, not a dealbreaker. At 2TB you roughly triple your installed-game capacity, and given it’s the sole drive here that drops straight into a PS5, it’s the clear buy for anyone reading this for its title. Get this one.
Installation is straightforward too. Power the console down fully, remove the side panel, open the M.2 bay, fit the drive at the right standoff length, and let the PS5 format it on first boot. The console then reports the drive’s read speed and lets you move games between internal and expansion storage. You’ll still store PS4 games on cheaper USB storage if you want, but PS5 games need this internal M.2 path to play directly. Simple, once you’ve got the correct drive.
Best System Alternative: MSI Codex Z2 Gaming Desktop
If your storage crunch has you rethinking whether to game on console at all, the MSI Codex Z2 at $2,067.34 is a full desktop for contrast, not a PS5 drive. It pairs an AMD R7-8700F with a GeForce RTX 5070, 32GB of DDR5, and a 2TB M.2 NVMe SSD, plus USB Type-C and a VR-ready spec running Windows 11 Home. Its 4.1 rating is solid for a prebuilt in this bracket.
Be clear on what this is. You can’t pull its 2TB NVMe and slot it into a PS5, so it doesn’t solve the console-storage problem this guide exists for. What it does show is where a couple thousand dollars lands if you’d rather move to PC gaming than keep feeding a console. For a PS5 owner who just needs more space, it’s the wrong tool. For someone at a crossroads, it’s a useful yardstick.
Best High-End Reference: ASUS Ascent GX10 AI System
At $3,970.99, the ASUS Ascent GX10 is the priciest item here and the furthest from a console drive. It’s a compact AI system built on NVIDIA’s GB10 Superchip with 128GB of LPDDR5x, a 1TB PCIe Gen4 NVMe SSD, Wi-Fi 7, and Bluetooth 5.4. It carries a 4.2 rating. This is workstation-class hardware aimed at developers and AI workloads, not a piece you’d ever install in a PlayStation.
We include it purely for transparency, since it appeared in this selection. Its 1TB Gen4 SSD is fast, but it’s soldered into a purpose-built machine, so there’s nothing here you’d repurpose for PS5 storage. If your interest is AI compute or a stackable small-form-factor rig, it’s worth its own research. If you came for a budget PS5 SSD, this isn’t it, and we won’t pretend otherwise. The Samsung drive above is your answer.
Buying mistakes to avoid
The biggest mistake is buying a drive that misses Sony’s speed floor. Any PS5 expansion SSD must be PCIe Gen4 and hit at least 5,500 MB/s reads, so a slower Gen3 drive simply won’t be accepted. The Samsung 990 PRO’s up-to-7,450 MB/s rating clears it easily. Confirm the spec before you buy, because a cheap drive that fails Sony’s check is money wasted.
The second mistake is skipping the heatsink. The PS5’s M.2 slot runs hot, and a bare drive can throttle without one, so either buy the heatsink model or add an aftermarket cooler. The third trap is confusing full systems with console storage. A prebuilt’s internal SSD, however fast, doesn’t transfer to a PS5, so don’t let a big spec sheet distract you from the one drive that actually fits the slot.
Also avoid paying extra for features the console can’t use. A Gen5 label, RGB heatsink, or bundled desktop cloning software won’t improve PS5 load behavior. The console wants a fast Gen4 M.2 drive with enough capacity and proper cooling. Put your money there. If two drives meet that spec, choose the one with the stronger reliability record and the lower price per terabyte, not the one with the louder box copy.
Bottom line
For expanding your PS5, the Samsung 990 PRO 2TB at $389.99 is the pick, and honestly the only one of these three built for the job. Its up-to-7,450 MB/s Gen4 speed clears Sony’s requirement with room to spare, and 2TB roughly triples your library space. Add a heatsink and you’re set.
The MSI Codex Z2 and ASUS Ascent GX10 are here for context, not console duty. If you’re a PS5 owner who needs storage, the Samsung is your buy. If you’re quietly weighing a jump to PC or AI hardware instead, those two systems show what the bigger budgets get you. For the slot in your console, though, keep it simple and grab the drive that fits it, then get back to filling it with games.
Common questions
Will the Samsung 990 PRO work in a PS5?
Yes. It’s a PCIe Gen4 M.2 2280 NVMe drive rated up to 7,450 MB/s, which clears Sony’s 5,500 MB/s recommendation for expansion storage. You’ll want the heatsink version or a separate M.2 heatsink so it doesn’t throttle in the console’s warm slot. Beyond that, it drops in and formats through the PS5’s storage menu.
Why are two full desktops in a PS5 SSD guide?
They were part of this selection, and we chose to be upfront rather than hide them. Neither the MSI Codex Z2 nor the ASUS Ascent GX10 is a console drive, so they can’t solve a PS5 storage problem. We kept them as price references for anyone weighing a move to PC gaming or workstation hardware instead of expanding a console.
Is 2TB enough for a PS5 library?
For most players, yes. A 2TB drive like the Samsung roughly triples your usable space beyond the console’s internal storage, enough to keep a couple dozen large titles installed at once. Modern games can exceed 100GB each, so if you install everything you buy, you’ll still curate. But 2TB dramatically cuts how often you delete and redownload.
Do I need a Gen5 SSD for the PS5?
No. The PS5’s slot is PCIe Gen4, so a Gen4 drive like the Samsung 990 PRO is the right match, and a Gen5 drive would run at Gen4 speeds anyway. Paying extra for Gen5 buys you nothing on the console. Focus on hitting the 5,500 MB/s read floor and getting the capacity you need instead, since that combination is what actually determines your PS5 experience.
Can I use one of these SSDs on my PC too?
The Samsung 990 PRO is fully at home in a PC, and its up-to-7,450 MB/s Gen4 speed suits gaming and workstation builds alike. The SSDs inside the MSI and ASUS systems are internal to those machines, so they’re not drives you’d buy separately. If you want one drive that serves both console and desktop, the Samsung is the flexible choice, and you won’t have to buy separate storage for each machine.
