Best PS5 and Xbox Storage Expansion for Autumn 2026's Biggest Game Releases
Best PS5 and Xbox Storage Expansion for Autumn 2026's Biggest Game Releases
Autumn 2026 is one of the heaviest release windows in years — Battlefield 6, Silent Hill: Townfall, Gears of War: E-Day, Call of Duty: Modern Warfare 4, and GTA 6 landing on 19 November are all arriving within a few months of each other. Every one of those installs eats into the roughly 1TB (825GB usable) of storage a standard PS5 or Xbox Series X ships with, and a Series S owner is working with even less. If you haven't checked your console's free space recently, now is the moment, because this is also the worst possible year to leave it until the last minute — storage prices have moved sharply upward in 2026, and waiting until launch week won't help.
This guide covers how much space this autumn's biggest releases actually need, your realistic upgrade options for PS5 and Xbox, and what's driving prices right now.
How Much Storage Do You Actually Need This Autumn?
Game sizes vary hugely, and it's worth checking before you assume the worst. Battlefield 6 has bucked the trend of ever-larger install sizes, with a leaked requirement of around 30GB — a genuinely small footprint by current AAA standards. GTA 6, by contrast, is expected to be one of the largest installs of the year: community estimates and leaks point to somewhere between 120GB and 200GB, and Rockstar's own advice ahead of launch has been to clear space well in advance, since the game must be installed on internal or officially expanded SSD storage — it cannot be played from an external hard drive on either PS5 or Xbox. Sensible planning is to assume the higher end of that range, particularly once day-one patches and any post-launch updates are factored in.
Stack GTA 6 alongside Battlefield 6, Call of Duty and whatever else is already installed, and it doesn't take much for even a 1TB console to run out of room — especially if you don't want to start uninstalling games you're still playing.
Upgrading PS5 Storage
The PS5 has an internal expansion slot for an M.2 NVMe SSD, sitting alongside its built-in storage rather than replacing it, and it's genuinely straightforward to fit yourself with a screwdriver and a few minutes.
What to look for in a PS5-compatible drive:
- PCIe Gen4 interface with a sequential read speed of at least 5,500MB/s — Sony's official minimum specification, which most current Gen4 drives comfortably exceed.
- A drive with a heatsink included, or a low enough profile to fit one separately. The PS5's expansion slot has strict height clearance, and running an NVMe drive without adequate cooling under sustained load can cause thermal throttling.
- Capacity: 1TB is the practical minimum worth bothering with given this autumn's install sizes; 2TB is the more comfortable choice if you're not planning to manage space carefully between games.
Popular current options include Samsung's 990 Pro range and WD's Black SN850X, both sold with official PS5-ready heatsink variants — check the listing specifies PS5 compatibility with the heatsink included, since the bare drive alone may not fit or cool adequately.
Upgrading Xbox Series X|S Storage
Xbox takes a different approach: rather than a standard M.2 slot, Series X and Series S consoles use a proprietary Storage Expansion Card that slots into the back of the console and is recognised instantly, with no setup, formatting or opening the console required.
The Xbox expansion card market shifted in 2026. Seagate was the original and, for years, only official manufacturer of these cards. Western Digital's WD_BLACK-branded cards have since been discontinued, following WD's broader strategic pivot toward hard drives over SSDs after its SanDisk spinoff. Filling that gap, SanDisk launched its own Optimus GX C50 expansion cards in 2026, becoming the third official option alongside Seagate.
Current published pricing for these official cards:
- Seagate Storage Expansion Card: originally launched at $199.99 (1TB), $299.99 (2TB) and $549.99 (4TB) SRP, though real-world street prices have climbed well above those original figures amid the wider storage shortage.
- SanDisk Optimus GX C50: listed at $109.99 (512GB), $199.99 (1TB) and roughly $340 (2TB) direct from SanDisk, with third-party marketplace pricing running higher depending on stock.
Because these cards are a proprietary format tied to licensing, they typically carry a premium over equivalent-capacity standard M.2 drives — but they're currently the only way to expand Xbox Series X|S storage for playing current-generation games, since standard external USB drives are limited to storing (not directly playing) Xbox Series X|S titles, and remain suitable only for older Xbox One-era games and archiving.
Why Storage Prices Have Jumped in 2026
If expansion cards and SSDs both feel noticeably pricier than they did even a year ago, that's not your imagination. The underlying NAND flash memory used in every SSD and expansion card has been caught in a severe supply crunch through 2026, driven by AI data centres switching aggressively from hard drives to SSDs and buying up flash memory production at a scale the industry wasn't built to absorb. Industry pricing has more than doubled since mid-2025, manufacturers have reportedly sold out their entire 2026 production capacity already, and analysts don't expect meaningful relief before new production capacity comes online in late 2027 at the earliest.

The practical takeaway: console storage expansion is not a purchase that's likely to get cheaper by waiting, and demand around a release as big as GTA 6 in November is likely to add further pressure on stock and pricing in the run-up to launch.
Buy Now or Wait?
Given the NAND shortage shows no sign of reversing before late 2027, and GTA 6's 19 November launch is a fixed, imminent date, waiting doesn't carry the usual upside of a price drop. If your console is already tight on space, buying your expansion drive or card in the coming weeks — ahead of the pre-launch demand spike — is the more sensible call than gambling on a discount that current market conditions make unlikely.
Buying Advice
- Check your specific console's free space now, not the week GTA 6 launches, when stock and pricing pressure will be at their worst.
- PS5 owners: buy a PCIe Gen4 NVMe drive rated for at least 5,500MB/s with a heatsink included or fitted, sized 1TB minimum.
- Xbox Series X|S owners: buy an official Storage Expansion Card (Seagate or SanDisk) — external USB drives can store but not play current-generation Xbox titles.
- Don't wait for a price drop. Current NAND supply conditions make a near-term fall in storage prices unlikely before late 2027.
- Size for the year ahead, not just the next game. With GTA 6, Battlefield 6 and more all landing in the same few months, a 2TB upgrade avoids the ongoing hassle of uninstalling and reinstalling games to manage space.
Frequently Asked Questions
Can I use a normal external hard drive for GTA 6 on PS5 or Xbox? No. Current-generation games on both PS5 and Xbox Series X|S must be installed on internal storage or an approved internal/proprietary expansion drive — external hard drives can store older, previous-generation game files but can't run current-gen titles directly.
Do I need an official Xbox Storage Expansion Card, or will any NVMe drive work? Xbox Series X|S consoles require the proprietary Storage Expansion Card format specifically — a standard M.2 NVMe drive won't fit or be recognised by the console's expansion port.
Is any PCIe Gen4 SSD suitable for PS5 storage expansion? Most current PCIe Gen4 drives meeting Sony's 5,500MB/s minimum will work, but check the specific drive includes or supports a heatsink that fits the PS5's expansion bay clearance — running one without adequate cooling risks thermal throttling.
Why are Xbox expansion cards so much more expensive than similar-capacity SSDs? They use a proprietary, licensed format exclusive to Xbox consoles, which carries a premium over standard M.2 drives, on top of the broader NAND flash price increases affecting all SSD-based storage in 2026.
How much storage will GTA 6 actually need? Rockstar hasn't confirmed an exact figure, but current estimates and leaks point to somewhere between 120GB and 200GB. Planning for the higher end of that range, plus room for day-one and post-launch updates, is the safer approach.
Final Thoughts
Between Battlefield 6, GTA 6 and the rest of autumn 2026's release calendar, console storage is about to come under real pressure — and it's happening at the same time NAND flash prices are climbing industry-wide with no near-term relief expected. Checking your free space and buying the right expansion option now, rather than during launch week, is the difference between a smooth upgrade and paying peak prices for whatever stock is left.
