Xbox Series X And Xbox Series S SSD Storage Explained

Here's what you need to know about the storage options and capacity of the Xbox Series X and Series S.

30 Comments

The Xbox Series X and Xbox Series S are both capable of loading game worlds almost instantly, delivering seamless gameplay that won't leave you waiting for minutes on a loading screen as an area is generated. This feature represents a sea change from the previous generation, and many generations prior, in which gamers have grown accustomed to long loading screens, cycling tooltips, and loads hidden behind elevator rides and tight crevasses.

That advantage compared to Xbox One is largely because of the new Xbox storage device, which is a custom NVMe SSD rather than the hard drives used previously. Below, we break down how it works.

Now Playing: Xbox Series X Load Time Comparison (RDR2, Control, FFXV)

How does Xbox storage work on the new systems?

Regardless of whether you get the Xbox Series X or Xbox Series S, your console comes with a custom Non-Volatile Memory Host Express solid-state drive: NVMe SSD for short. It's small, loads incredibly quickly (as we found in our Xbox Series X hands-on), and because it's an SDD rather than a hard drive, there aren't moving parts. It also helps to facilitate the system's impressive Quick Resume feature.

Games install to this drive much like they do on current-generation consoles, and because even the fastest disc drives aren't up to the challenge, you must fully install games onto the drives to play them on Xbox Series X and Xbox Series S. For the X model, you get 1TB of internal storage, while the S has 512GB.

But the storage you start with isn’t necessarily all you have to use. Both consoles feature an expansion slot. Starting with a proprietary 1TB expansion card from Seagate, Microsoft is offering players the chance to upgrade their storage space. All you have to do is plug it into the back of your system to add on another 1TB of space, and it supports both Xbox Series X and Xbox Series S. New sizes and manufacturers could come in the future, and the first card costs $220.

Do Xbox Series X and S support external hard drives?

Both consoles do support hard drives for some content, provided they use USB 3.1, and you can actually plug your current compatible drive into the new console and instantly begin playing any games you had installed. The drive can store and play any Xbox One, Xbox 360, and original Xbox game that supports backward compatibility, and it can also store your Xbox Series X and S games. It's a cheaper alternative to the new proprietary cards.

However, hard drives aren't fast enough to actually run the Xbox Series X and S games, so you will need to migrate them to your internal storage or the official expansion card before they can be played. If you have the expansion card installed, Xbox Series X/S games on the card can be played without needing to move them to the system's internal storage. The expansion card is designed to run these games with no performance differences compared to the internal drive.

Why is the expansion card so expensive?

No Caption Provided

Yes, this is a bit of a hard pill to swallow. The expansion card costs nearly as much as the Xbox Series S.

While you'd have to ask Microsoft or Seagate for an exact breakdown of the costs, NVMe SSD technology is still fairly new and allows for much better performance compared to older flash and hard drive technology. There aren't any other options on the market for an external expansion card for Xbox Series X and S yet, and that could cause prices to fall a bit. However, current drives for PC that are in the same general performance range, or even slightly worse, are not much cheaper.

You will likely find similar issues with pricing on the PS5, as well, as it's making use of very similar technology as Xbox. In that case, the PS5's internal storage is 825GB, meaning it's actually less than the current PS4 Pro and a little less than Xbox Series X. Game file sizes are getting larger, especially as they add post-launch content, and with some of a console's storage space allocated for system-level files, you will have even less space to work with. It's something important to consider when picking up a less-expensive console like the Xbox Series S. With only room for a few next-gen games, you could need to make up that price difference with an expansion card very quickly.

As long as I can store games onto andm external drive and for mass storage and transfer them to the internal SSD or download them ahead of time I'm cool.

And can I just say that pre-install games in advance is my new favorite feature? I already have AC Valhalla and Gears Tactics pre-installed on my One X so when I get my Series X I can play the games on my One X while I wait for them to install on my Series X. I was getting Avengers through GameFly, which is trash, so instead of having to wait for it to install I pre-installed it, popped in the game disk, and got right to playing it. I hope the PS4 and PS5 adopt this feature.

My only major issue is that it only has 1 expansion slot. It's like they only halfway thought of future-proofing.

What happened to the GameCube era when they gave us 2 memory expansion slots for the GC, PS2, And OG Xbox. Do they not want any more money out of us?

@illegal_peanut: why do you need 2 when all they have to do is just increase the size from 1 to 2TB and sell it to you for 400 bucks. I think we will definitely see a 2TB option somewhere in the near future. probably some 2 or 3 years when the 1TB price decrease to 150 or lower they will sell you the 2TB for at least 250

@illegal_peanut: I wonder if it's a hardware type issue and they only had room on the board for one expansion slot. Seems like they would want a few more to take our hard earned cash.

Ssd drives are expensive right now ! But what I want to know is on either console can you eject the disc from the controller or do you push a button on the console itself?

That is how much NVMe SSD cost? Everybody was all for it till they found out how much it will cost them. Instead of higher CPU and GPU you get the NVMe SDD so what you get is a cheaper upfront cost In hopes you buy an additional SSD. What is even worse is that the PS5 SSD uses even newer technology increase the cost even more so.

IMO if the generation ends up only lasting 5 years that premium cost you might be paying for additional SSD may not be worth it especially since PS5 SDD has to be P$5 approved.

@systemoverload: it won't be that much more and definitely more bang for your dollar. For example the Samsung ssd that just released is only $10 More. This application that MS is a much worse value when comparing speed's. That's the downside of proprietary.

As much as I like SSD/NVME drive there price of and lack of size is huge turn off the speed is not worth it all gona be doing uninstall and reinstalling games constantly cause the size of game are gona bloat up again 100-150gb some current gen games are next gen watch 150-200gb

There is reason why Mechanical drive are still thing even in 2020 for price of 1 tb NVME and SSD in most cases you can get 4gb or higher capacity NVME and SSD price need to dramaticly come down in price. that or they should just ship the physical copies of games on NMVE/SSD that we just plug in to system. and we dont have worrry about how small and expensive these drive are then again they would use that reason to charge 100+ for game which would be neo geo game prices which was one reason why it failed so bad.

God I miss games that ran of cartridge and disc.

@tsunami2311: Prices have fallen by a large margin for SSD NVME m.2 pcie 3 and 4th gen sticks at a point that 500-1tb is 60-120$, 100-180 for gen4.. Compare to just 2 years ago when these started hitting the market were 300-400 % higher in price. With predictions that these forms of storage will actually outpace even traditional HDD in total storage.

So actually, size, speed, an price of NVME is a much better option now, and future. https://www.howtogeek.com/404627/what-are-nvme-drives-and-should-you-buy-one/

Luckily both 9th gen consoles let us have a mix of nvme, hdd, and cloud support that a common gamer will not care one way about larger storage, heavy gamers can pay more for not only size but speed, and hoarders can have cheap access to just total size.

But as a gamer and consumer, I am much happier with the future minded NVME then the HDD.

Two things though: I really wish that all consoles gave free subscription less cloud storage (upto a reasonable amount). For saves and other stuff.

Also wish xbox allowed the hot swap, like sony of a straight nvme,- either 3 or 4th gen instead of proprietary. The 220$ gen 4 is higher then current equivalents, like https://www.amazon.com/GIGABYTE-PCI-Express-Interface-Performance-GP-ASM2NE6100TTTD/dp/B07TJWZGL9 @ 180 @170 . I am fine with them drawing a line at gen 4 because these are out with many manufacturers, seem durable, and prices are falling, by this time next year the prices should be down to near $100. Or instead of the proprietary unit above, is to sale us a dongle that would allow us to swap any brand and any size. Like some people will do just fine with a 500gb.

So far ps5 has not announced what storage they are using, probably gen 4 NVME, which is crazy considered how soon the launch is.

Just get a PC, even with Xbox Game Pass it's a cheaper, more versatile option in the end.

@Crazy_sahara: Thing is with a Series S you'd most likely run into the issue of third party games being made for the Series X and not S due to it's weaker hardware. I am sure MS will be supporting it, but I wouldn't be surprised if in 3 years from now a new, dunno Assassin's Creed or something, will not be coming to Series S. But, we'll have to see how it goes.

@Hondje89: the series s is a beast, 500gig nvne, 8 cores 8 threads, amd 6600, a architecture built entirely away from pc, but for pc, able to play 1440 at 120fps, and goes 4k on older 360 games... And supports ray tracing capabilities with Atmos, and HDR built in, and a modular power brick, with a console smaller and sleaker then my pc...

I could put 20 of these in my pc, and it will not only be faster lol, but still cheaper then my pc that's outdated and would have to sell for more with a huge loss. Scaling from 1080 to 4k, isn't complex, hell the 3090 does it, it pushes 1440p to 8k upscaling via compute cores and tensor cores. It's not true native 8k but it's expensive.

So the series s is a beast for $299 USD and $499+ international

@Hondje89: I thought I had watched a video stating they are capping the Series S to a max of 1440p so that should def help out if true.

@Hondje89: I don’t see why that would happen, the difference between them is basically the graphics card, and PC has always supported different levels of graphics. Just reducing from 4k to 1440p and from 120 to 60 fps is probably enough, not even changing levels of detail or lighting

I'll probably wait until there's a 2TB version then; waited for the 1TB Xbox to get released before I made the jump this gen and that paid off.

Looks like storage will be be the main headache on both consoles this gen though :( .

I'm really not too happy about this, but hopefully by the time I actually need the space, these things have more manufacturers on board and come down in price a bit.

@jbreez00: That was the whole point of the story above was that this is a 'proprietary' drive by one manufacturer. Hence the term, proprietary.

I mean yeah, a few years down the road, xbox could open it up to other brand (there are already dozens of manufacturers of nvme 4th gen at comparable or faster speeds for $170+ and prices if following the curve are quickly getting cheaper every single month) but the thing is, if you make a proprietary deal to create a pluggable card like one above, then they are going to write into the deal a strong time limit to protect their investment. I would bet years.

That similarly-priced NVMe drive you linked on Best Buy's site is a faster one, it can do 3.5GB/s while the Series X/S storage is 2.4GB/s.

1TB NVMe drives with lower, more comparable speeds tend to be around $130, so yeah these Xbox cards do still feel way overpriced

@Spartan_418:Both the PS5 and Xbox use a custom system delivering more priority lanes among other dedicated hardware like a custom I/O unit and flash controller (I don't remember if Sony named their system but the Xbox one is going by Velocity). Standard NVMe drive arhcitecture uses only 2 true priority levels, but the Xbox/PS5 use 6 priority levels.

Which means standard NVMe drives need extra speed to make up for that difference. You basically need to brute force the difference by using a faster drive. This is why despite a 5.5Gb/s speed on the PS5, Sony expects you will need approximately a 7Gb/s NVME drive to compensate for that difference between priority levels.

As Cerny puts it, its an Apples to Oranges comparison but in short, you basically need to be comparing it to a faster NVMe, not one of the same speed.

@fitzy_2812: Just to clarify, there has been no set information on ps4 NVME set specs as of right now. Which is also crazy considering how soon the launch is. There has been no line in the sand drawn in regards to speeds, and the entire game does not have to be on the internal nor does the add on NVME have to be of equal speeds for the games to run off the external add on nvme.

Again, speculation as no set information has come out. I myself would like the option to drop in any NVME 4th gen stick and of any size on the xbox. But who knows maybe prices will drop pretty quick on the proprietary storage above, though unlikely anytime soon.

IT would also be nice if xbox and sony would have added a thunderbolt port fast enough to allow for a external NVME HDD either pcie 3 or 4gen, that would allow playing games off the drive in regards to what ever speed they are.

@cylor: This tells me either two things. That- One, they do not even know what form or factor their engineers have or will eventually have in regards to add on storage, and are waiting as long as they can before announcing prices and specs, since storage supply is still a moving target. Will they allow gameplay from the NVME at all? Will they reduce speeds from their very fast internal memory to allow for any 3 or 4th gen storage to play game from it ? Will licensing NVME be more profitable if storage keeps dropping like a rock? And can all of these decisions change with just an update, later on down the road?

or Two- that they know and have decided already but will release this along with other information about the PS5 like they have been all year long. Holding tightly to their vest and waiting for the public relations, Meet the Cardasians, moment. Causing netizens like us, to muse about it on comment sections, till launch.....

@Spartan_418: or twice that uncompressed, and the PS5's will be even faster. Plus it's plug-and-play.

It's in the same general ballpark so I really expect to see similar prices on PS5-certified SSDs down the line.

@gabegurwin: No set information so far, but the speeds do not have to be the exact same as the internal for games to play off the add on nvme drive. It will probably be set along the line of samsungs 7,000MB/s and 5,000MB/s, or two times faster then 3rd gen., but there is already other manufacturers at the same speeds and cheaper 170$ and up. Prices seem to falling, every month, I would not be surprised if by this time next year the prices would be around 100$.

Again no set information has come out, and time is a ticking.
