The Xbox Series Storage Architecture: Proprietary Cards, SSD TBW Degradation and the "Brick by Design"

I briefly owned an Xbox One X, and managing storage on that platform was a breeze. When I upgraded to an Xbox Series X (following an issue that later turned out to be a bug in an EA title), I entered a whole new ecosystem of storage frustration. I have a lot of titles so am probably an edge case but the fundamental issues I face, impact every Xbox owner today.

On the Xbox One generation, expanding storage was straightforward and consumer-friendly. You could swap the internal drive or simply plug in any cheap, off-the-shelf external USB hard drive to store and play games directly. Because game libraries aren't critical data like family photos, you didn't need expensive redundancy; if the drive failed, you just claimed a warranty replacement and re-downloaded your games.

With the Xbox Series X|S generation, Microsoft introduced "Smart Delivery". When you download a title, the system detects your console and forces the installation of the Series X|S optimised version. However, Series X|S native titles cannot be played from a standard USB external drive - they must run directly from the fast internal SSD (or a proprietary expansion card); and they are generally much larger. (USB external drives can only be used to store Series games or play legacy Xbox One/360 titles.)

Because internal SSD capacity is capped (ranging from 512GB on the Series S up to 1TB or 2TB on high-end Series X models), storage fills up quickly. Modern games regularly exceed 100GB (CoD HQ/Warzone ~160GB, Red Dead Redemption II ~120GB, NBA 2K25 ~115GB) and some titles balloon like MS Flight Simulator 2024 which can be up to 600GB if you include the optionals. This leaves users trapped in a constant cycle of deleting, re-downloading, or shuffling files back and forth between internal and external drives just to free up playable space.

To bypass internal storage limitations, Microsoft requires users to buy proprietary Storage Expansion Cards using a custom form factor. They were initially made only by Seagate (now WD as well) but the prices for these expansion cards remain ridiculously high (c.f. open-market PC hardware). Right now, the 1TB storage expansion card is nearly £300 on Amazon and the 2TB is £500. There may be incidental minor discounts but essentially the prices approach that of a new console! 

Whether or not you pay (through the teeth) for an expansion card, if you have a reasonable game collection, you must constantly add and remove the Series games on and off the internal drive and all this causes wear. All NAND flash memory inside the SSDs have finite write endurance (measured in Terabytes written - TBW). So every time a game is written or updated (and most updates effectively re-download the entire title), the internal drive's flash memory degrades. Once the drive reaches its TBW limit, it fails and causes corruption - and then the console is effectively unusable.

Microsoft do not let people see the underlying internal drive's wear or even rudimentary (SMART) drive health so you have no idea how the drive is doing and when it is about to fail. But this problem becomes really dark: The drive is encrypted and paired to the console (on a hardware level). If it fails, you cannot simply get a replacement, the console will fail to boot. Some people suggest, for the very tiny geeky minority of Xbox gamers, to dismantle the hardware and use specialised hardware flashing tools to copy low-level partitions from the dying chip but this is not a realistic expectation for the typical gamer.

When the drive fails (and it will definitely fail as all SSDs will do due to TBW), the only option is then an aftermarket repair from Microsoft for £300 with a paltry 6 months warranty - again approaching the cost of a new console! Combined with Microsoft's persistent refusal to adopt drift-resistant Hall-effect magnetic thumbstick sensors in standard controllers (which would significantly increase controller longevity), this design choice points to deliberate planned obsolescence.

One of the workarounds some people used for this issue was to xCloud (Microsoft's Cloud gaming service). I would deliberately avoid installing a Series title (where the latency wasn't critical to a game) so the Xbox Store would present the option to stream the game (i.e. play it remotely and not locally). This meant I could reduce the wear on the internal drive (from un/installing games). But Microsoft have effectively closed that 'loophole' now - and monetised it - xCloud now has usage limits. It's bad enough paying for Game Pass Essential (their most basic subscription plan) at £7 per month just to be able to have multiplayer online (which is free on PC) but now instead of unlimited cloud gaming, you only get 5 hours per month included - it's more like a demo.

Storage is the "printer ink cartridge" of the Xbox ecosystem. You don't notice the hidden costs initially but they are very real and it's a high-margin proprietary trap to force captive pricing on users. But with the inevitable internal drive failure (expedited for reasons above), this is beyond planned obsolescence - it is "brick by design".

The Xbox for me sits at intersection of unscrupulous US corporation and entertainment.  Gamers are locked into overpriced proprietary storage, forced to wear down an irreplaceable internal drive, and ultimately left with a console designed to fail without a cost-prohibitive repair. I think the *only* hope for breaking this horrible business model is EU right-to-repair legislation that penalise corporations like Microsoft who would rather fill up landfills and shareholder pockets than provide a honest entertainment service. And it's more horrifying when you think, despite the average gamer being adult age, Microsoft's main target is children - to keep their market share.
