Best PS5 SSD Upgrades for GTA 6: Which Drive to Buy, What to Skip, and How to Install It

GTA 6 is going to be big in every sense, and storage is where that size stops being exciting and starts being a problem. The reported download size on PlayStation 5 sits at around 210GB, which means a launch console with a few other games already installed may not have room for Leonida at all. The fix is not complicated, but it is easy to get wrong: buy the wrong drive, skip the heatsink, or leave the upgrade until pre-loads open, and you will be the person deleting games in a panic while everyone else is already downloading.

This guide covers the whole decision in one place. How much space you actually need, what Sony requires from a PS5 drive, which SSDs are worth your money, which ones to avoid, and how to fit the drive yourself in about ten minutes. No affiliate links are included here, because none have been set up for this guide yet — the recommendations stand on their specs and their track record, not on a commission.

Why GTA 6 changes the storage maths

Start with the number everyone is working from. PlayStation Store backend data tracked by PlayStation Game Size puts the GTA 6 download on PS5 at around 210GB, and Insider Gaming has said it can corroborate that figure. Rockstar has not announced an official file size, so treat 210GB as the best reported figure rather than a confirmed fact. It is, however, a very credible working number, and it is the one to plan around.

On a launch PS5, that is nearly a third of the usable drive. The original console ships with an 825GB SSD, of which roughly 667GB is actually usable once the system software takes its share. Subtract a reported 210GB for GTA 6 and you are left with around 457GB — before a day-one patch, before future updates, and before any of the online content that will inevitably follow. The slimmer PS5 with a 1TB drive leaves roughly 848GB usable, which is far more comfortable, while the PS5 Pro with its 2TB drive leaves around 1.89TB usable and barely notices the game at all.

The practical target, then, is not exactly 210GB free. Aim for around 250GB free instead. That buffer covers a day-one patch and the temporary extra space console updates sometimes need while they install. If your console cannot clear that bar with games you are willing to move or delete, an SSD upgrade stops being optional and becomes the plan.

That is also why this guide pairs so naturally with the wider launch preparation. Our GTA 6 pre-load guide walks through clearing space and getting the download ready a week before launch, and our report on the reported 210GB install size explains where that figure came from and why it should still be treated as unconfirmed. Read those two first if you have not already checked how much free space you actually have, because the number in Settings, under Storage, is the only one that matters for your console.

What a PS5 actually accepts

Sony’s rules for the PS5 expansion slot are precise, and every drive in this guide meets them. Get these right and almost any modern drive works. Get one wrong and the console may refuse the drive or run it slower than expected.

The drive must be a PCIe Gen4 x4 M.2 NVMe SSD, in the Key M socket type. SATA M.2 drives are not supported at all, no matter how fast they look on the box. Capacity can run from 250GB up to 8TB, and the supported lengths are 2230, 2242, 2260, 2280 and 22110 — in practice, almost every drive you will buy is 2280, the standard desktop size. Sequential read speed should be 5,500MB/s or faster, which is Sony’s recommended minimum. Cooling is required, not optional: the drive needs a heatsink or a heat transfer sheet, and the whole assembly must fit within 110mm long, 25mm wide and 11.25mm thick, with no more than 8mm of that above the board.

Two details catch people out more than any others. First, the heatsink is the part most likely not to fit. Some PC heatsinks are too tall for the PS5’s slot cover, so the safest purchase is a drive that comes with a PS5-compatible heatsink already fitted, or a slim heatsink made specifically for the console. Second, never stack a second heatsink on a drive that already has one — Sony warns that it can make the built-in cooling less effective, not more.

One more honest caveat from Sony itself: even a drive faster than 5,500MB/s is not guaranteed to match the internal SSD in every game. In practice, the drives below all clear the bar by a wide margin, and load times in open-world games are governed far more by clearing that bar than by squeezing out the last few hundred MB/s on a spec sheet.

What about Xbox?

Xbox owners have a different, simpler problem. There is no M.2 slot to fill. Current-generation Xbox games must run from the internal SSD or from a Storage Expansion Card built for the Xbox Velocity Architecture — the Seagate and WD cards sold for the Series X and Series S. A USB drive can store Xbox games and hold them ready to transfer, but it cannot play them directly, and the same limitation applies on PS5: USB extended storage is fine for holding PS4 games and for parking PS5 games you are not currently playing, but a PS5 game has to be copied back to internal or M.2 storage before it will run.

That makes the Xbox decision a price question rather than a compatibility puzzle. The expansion cards cost more per gigabyte than a PS5 M.2 drive, and the Series S is the console under the most pressure, with roughly 364GB usable from its 512GB drive. If a reported 210GB install lands on a Series S, it takes well over half the usable space. Series X owners, with roughly 802GB usable, are in far better shape. The rest of this guide focuses on PS5, because that is where buyers have real choices to make — and real mistakes to avoid.

The picks: five drives worth buying

Prices for SSDs have climbed sharply, driven by NAND shortages, so treat any price you see as a snapshot rather than a promise. The ranking below is about the drive, not the deal of the day: buy whichever of the top two is cheaper when you shop, and do not overpay for a brand name when a cheaper drive clears the same bar.

Best overall: WD Black SN850X with heatsink

The SN850X is the drive most PS5 owners end up with, and for good reason. It reads at up to 7,300MB/s, comfortably above Sony’s minimum, and the heatsink version fits the PS5 slot without fuss. WD also sells the SN850P, essentially the same drive sold as an officially licensed PS5 product, but it usually costs more for no real-world gain. If the SN850P is the same price, take it for the peace of mind. If it is not, the SN850X is the same drive in practice.

Fastest on paper: Samsung 990 Pro with heatsink

Samsung’s 990 Pro with heatsink reads at up to 7,450MB/s, the highest figure in this group, and its slim heatsink is built to fit the PS5 bay. In real gameplay, you will not feel the difference between 7,300MB/s and 7,450MB/s — both are far beyond what the console needs — but if the Samsung is cheaper than the WD on the day you buy, there is no reason not to take it. Buy the heatsink version specifically. The bare 990 Pro is a superb PC drive and an unfinished PS5 upgrade until you add compatible cooling.

Best value: Crucial T500 with heatsink

The Crucial T500 with heatsink reads at up to 7,400MB/s and frequently undercuts the two flagships on price while matching them on speed. Its endurance rating is strong, and Crucial describes the heatsink version as ready for consoles. This is the pick for buyers who want flagship speed without paying the flagship premium, and it is the drive to check first if the WD and Samsung are both priced high when you look.

Best mid-range alternative: WD Black SN7100

WD’s newer mid-range drive reads at up to 7,250MB/s, well over Sony’s requirement, and usually costs less than the SN850X. The catch is that it does not come with a heatsink in most listings, so you need to add a slim PS5-compatible heatsink and check the total thickness against Sony’s 11.25mm limit before you buy. If you are comfortable with that one extra step, it is excellent value. If you are not, spend the difference on a drive with cooling included.

Best budget pick: Crucial P310 with heatsink

The Crucial P310 hits around 7,100MB/s and is one of the cheapest drives that clears Sony’s bar comfortably. Crucial sells it with a heatsink in some sizes, and that is the version to buy. A budget drive only stays a bargain if you do not have to buy cooling separately, so check the listing carefully: the product name must say heatsink, not just the drive family.

Worth a mention: Seagate FireCuda 530 with heatsink

Seagate’s FireCuda 530 with heatsink reads at up to 7,300MB/s and carries a particularly strong endurance rating, which matters if you write and rewrite large games constantly. Make sure you get the heatsink SKU rather than the bare drive of the same name. It is rarely the cheapest option, but for heavy users who keep a large library churning, endurance is a genuine reason to pay a little more.

1TB, 2TB or 4TB?

For GTA 6 alone, a 1TB drive is plenty. It adds roughly 1,000GB to your console, which covers the reported 210GB install several times over and leaves room for a healthy rotation of other games. It is also the cheapest way to remove the storage anxiety entirely.

Go to 2TB if you keep a lot of games installed at once, if you share the console with family, or if you simply never want to think about storage again until well after launch. At current inflated prices, 2TB drives from the big brands sit roughly in the $330-and-up range, which stings compared with recent memory — but it is still cheaper than replacing a console, and it is the capacity most buying guides now default to for a game of this size.

Skip 4TB unless you genuinely maintain a huge library or you are buying for a PS5 Pro household where the console is the main entertainment machine. The price jump is steep, and most players will never fill it. The one exception is if you find a 4TB drive at a small premium over 2TB during a sale — then take the extra space, because you will grow into it eventually.

A final word on timing: do not wait until pre-loads open to buy. Fitting a drive takes minutes, but it requires formatting, and formatting erases anything on the drive. You also want time to move games across, test the drive, and fix any problem while there is still a calm evening to do it in. Our GTA 6 launch day checklist puts storage in its proper place — one job among several to finish before Leonida opens, not a last-minute scramble.

What not to buy

The wrong drive is almost always one of the same few mistakes. PCIe Gen3 drives are cheaper for a reason: the PS5 needs Gen4, and a Gen3 drive may not install or will load games slower. Cheap DRAM-less drives that fall below 5,500MB/s are a similar trap — the headline price hides a drive that misses Sony’s recommendation. SATA M.2 drives, which look identical to NVMe drives at a glance, are not supported at all.

PCIe Gen5 drives are the opposite mistake: paying extra for speed the console cannot use. Sony specifies a Gen4 x4 slot, so a Gen5 drive will work at Gen4 speeds at best, and you will have paid for performance that stays on the table. Similarly, do not buy a bare drive and assume any old heatsink will do. Check the assembled height against the 11.25mm limit, buy a heatsink made for the PS5 if you need one, and never double up cooling on a drive that already has it fitted.

And beware of listings that hide the details. If a listing does not state the sequential read speed, does not say whether a heatsink is included, or does not give the exact model number, do not buy it. The exact SKU matters — several drives in this guide have a bare version and a heatsink version with near-identical names, and only one of them is ready to install.

How to install it, step by step

You need one tool: a small Phillips-head screwdriver. Update the PS5 system software first, because older software may not support larger drives properly, and the reported firmware requirements around launch make that step more important than usual.

Power the console off fully — not rest mode — and unplug every cable. Lay it on a flat surface with the logo facing down and slide the side panel off. Underneath, a small metal cover held by a single screw protects the M.2 expansion slot. Remove that screw and the cover, and keep the tiny screw somewhere safe.

Inside the bay, you will find a retaining screw and a spacer. Move the spacer to the hole that matches your drive’s length — 2280 for almost every drive in this guide. Slide the SSD into the connector at an angle, press it flat against the spacer, and fasten it with the screw. It should sit firmly, with no wobble. Replace the slot cover and the side panel, plug everything back in, and power on.

The console will detect the new drive and offer to format it. Accept — formatting erases the drive, so make sure it is empty or holds nothing you need. Once formatted, go to Settings, then Storage, and you can set new installs to go straight to the M.2 drive, or move existing games across to free up the internal SSD. Either way, GTA 6 can now install directly to the new drive, and the internal storage stays free for system use and smaller games.

The whole job takes around ten minutes, and it does not void your warranty — Sony designed the slot to be user-accessible. If the console does not recognise the drive, power off, re-seat it, and check the heatsink height and the spacer position before assuming the drive is faulty. If the PS5’s own read-speed test reports a number below 5,500MB/s, double-check that you bought a Gen4 drive and that no second heatsink is interfering with the fit.

After the upgrade: getting the most from the space

An SSD upgrade is only useful if you use it well. Set the M.2 drive as the default install location so new games land there first, and keep the internal SSD for the games you play most — although in practice, with speeds this high, there is no performance reason to prefer one over the other. Move your biggest back-catalogue games to the new drive in one sitting, rather than shuffling them one at a time whenever space runs short.

Use a USB drive as cold storage, not as a playing drive. Park the games you are not currently playing on USB, where they wait without a re-download, and copy them back when you want them. That combination — a large M.2 drive for active games, USB for the archive — is how a launch PS5 survives a 210GB game plus a normal library without constant deletions.

And do not forget the rest of the setup. A bigger drive does not help if the screen or the sound lets the game down, so our guides to the best TVs for GTA 6 and the best gaming headsets for GTA 6 are worth reading alongside this one. Storage gets you into Leonida. The screen and the sound decide how good it looks and feels once you are there.

Frequently asked questions

Will a faster SSD make GTA 6 run better? Above Sony’s 5,500MB/s bar, the gains are small. A compatible drive loads the game and streams its world smoothly, but it will not raise the frame rate or improve graphics. Buy for capacity and compatibility, not for the last few hundred MB/s on a spec sheet.

Can I play PS5 games from a USB drive? No. PS5 games must run from internal or M.2 storage. USB drives can store them and hold PS4 games for direct play, but a PS5 game has to be copied back before it launches.

Does the PS5 Pro need an upgrade for GTA 6? Almost certainly not. With around 1.89TB usable, the Pro absorbs a reported 210GB install easily. Pro owners should still check their free space, but an upgrade is a luxury, not a necessity.

Is the reported 210GB size final? No. Rockstar has not confirmed it, and a day-one patch could push the total higher. That is exactly why this guide recommends around 250GB free rather than exactly 210GB.

What if I buy the wrong drive? If it is unopened, return it. If it is installed and the console rejects it, check the spec sheet against Sony’s requirements — interface, speed, size and heatsink height — before concluding the drive itself is at fault. Most rejections trace back to one of those four checks.

The bottom line

GTA 6’s reported size is the storage story of this launch. A launch PS5 owner with a full drive is one big download away from a problem, and the solution costs less than the game itself if you buy the right capacity. A 1TB drive solves it. A 2TB drive solves it for years. Either way, buy a Gen4 NVMe drive at 5,500MB/s or faster, with a PS5-compatible heatsink fitted, fit it ahead of pre-loads opening, and set it as your install drive.

Do that, and the only thing left to worry about ahead of November 19, 2026 is what to play first in Leonida — not whether there will be room for it.
