as long as it is PCiE4, with >6.5gbs spec...which iirc, not in the markets as of now...
And it has to fit the M.2 slot, which unfortunately may not always be the case as I believe there's not a firm standard for these even though that long bubblegum stick shape seems to be sticking. (You actually have to check size a lot of times on your home PC, especially if you're adding a new M.2 to your laptop.) We haven't heard anything new about PS5's expansion slot, and by the time users actually need space to add on the drives they need may be abundant and slowly coming down in price (everybody's eager to get into Sony's market, and this being really the dawn of regular-consumer demand for M.2 (PCs have had access to them for a while but I don't know that your average PC user has messed with them yet, even if they've in the past change out their own HDDs?), so there will be an expanding range of choices for PS5 owners, but at November's launch, choices will be slim if any.
Microsoft's add-on is encased and will only have a few SKUs of sizes, so in a way it's good they have consumer-ready design ... but this being a proprietary card, you'll have to pay what MS charges.
How much is an external 1 tb SSD drive these days? Most seagate ones seem to be close to 200 dollars on amazon or at least 150 dollars.
Pricing SSDs is super confusing because there's sizes and there's speed and MTBF ratings and M.2 versus SATA and PCIe versions and a mess of other acronyms and codenames and stuff (and the card that Microsoft showed off looked to be the size of like a matchbook, which I'm not sure matches any sizes I can find in M.2, it looks kind of more like an mSATA card in a case?) Xbox Series X/S Expansion Card provider
Seagate has a couple products to look at in comparison, sort of: the
Seagate Firecuda 510 M.2 M.2 2280 double-sided (3450MB/s Read) goes for $190 for a TB, and the
Barracuda 510 M.2 2280
single-sided (3400MB/s Read) goes for a little less at $150 for 1TB. And the Xbox Series X itself depends on its SSD rated at just 2.4GB/s speed. So...math.
(...it's late, somebody please correct everything I got wrong. But even if this "leak" is bullshit, anybody expecting add-on SSDs to be cheap this November is bound to have a bad time in store for them.)
Uh boy, that recalls "the good old times" where you had to sell a kidney for a memory card.
Right? I get it, there's pain to new system purchases, but as an old-timer, it does feel a bit weird to me that everybody's expecting the Series X and PS5 to have everything the consoles will ever need right in the box for one friendly price tag. It wasn't too long ago for me when the HDD-less Xbox 360 Arcade package shipped with so little storage space that MS had to force developers to slice their games up so that some of them could cram them on the 256
MB storage drive; the $150 "HDD Tax" got you an add-on 120GB that made the hardware viable finally. And before that Memory Cards were a pre-requisite buy for every console you owned (and not just one but a handful and sometimes even a half-dozen memory cards were needed if you really gamed hard.)
Kids these days...
