That has hurt Microsoft this generation compared to Sony's BYOSSD functionality.

Actually so can xbox users, just need an m.2 to cf express adapter. Although larger ssd's are less practical. Ca still use a 2tb m.2 30 with an adapter for an okay price.

I bought a 8TB WD black M.2 drive for $600 recently.

$499 for 4TB is a massive ripoff.

You'd think MS would have learned after the Vita failed in no small part due to its proprietary memory, but NOPE.

Situation is very much not the same, the standard is based on CFexpress, there are adapters ouf there, and multiple manufacturers. Sure it is still more expensive, but 4tb in that form factor generally would be.

I would say think psp with memory stick would be closer than ps vita with no internal storage and it clearly being meant as an upsell.

And that is a problem Microsoft entirely made for themselves. Nothing is stopping them from having made an xbox with a standard M.2 like the PS5, or making their own hot swappable M.2 enclosure.

The Vita is a lot more comparable. When the PSP came out in 2005, the PS2, xbox, and gamecube all used proprietary memory cards. The GBA didnt have any removable storage. SD cards were still new, and had a reputation for being rather unreliable. They were also slow and capacities above 4GB were rare and expensive, tot he point that the 16 and 32GB pro duo cards were comparable to SD options of similar quality. Sony at the time was trying to make the stick a standard form as well, their laptop line had native MS pro duo slots.

By the time the Vita came out, the market had changed drastically. The DSi had normalized the use of SD cards. The 3DS also used a SD card slot. The Wii used a SD card slot. The PS3 used a normal HDD, and the xbox, while using its special enclosure, could use third party drives with free tools. SD cards had also changed significantly, with far higher capacities, lower prices, faster speeds, and greater reliability.

So the Vita launching with a proprietary and expensive storage medium was a very stupid move. It was brought up in every review, and many like myself were waiting for the prices to come down on the media like they had with the MS pro duo, as the vita games were much larger than PSP games. Forums complained about it regularly. Just like the Xbox series.

Apparently Microsoft has locked out that option, based on reviews of the adapters.

I stand corrected then, in that case. Shame.

Making some good points, still I would not say the xbox series situation is entirely comparable to the vita one.

Biggest point is at the time of the vita, you really had to buy the extra storage, at rather terrible prices. the xbox series at least comes with a decent amount of internal storage. Besides that there are 2 vendors selling them right now, and given the niche form-factor the prices are not that outlandish.

I would also argue that, if you don't want your users to screw in m.2 ssd's (which is a barrier to some). There are no good other standards that offer that. Nintendo's solution of reviving SD-express still is a slower standard and price wice worse. Still if only they just allowed those third party adapters to generally work.

I still prefer Sony's solution on ps5 but for user convenience it is not the worst.
It really is not the slap in your face that was the 0 storage PS-Vita with little reason why they had to use proprietary cards.

It's a duopoly for these expansion cards. Way too expensive! I've been trying to get on for a friend for a b-day, just can't justify the price.
Edit: Seagate is not even selling the 512GB card anymore.

"The 4 TB Seagate Storage Expansion Card for Xbox Series X|S is now available for $499.99"

After exchange rate and taxes that's double what I paid for the xboxS and a controller I think?

Shame they don't have a Thunderbolt or USB4 port on them. An external drive would be a nice option.

I kid you not, the price of Vita memory cards is what stopped me from buying it.
