I’m thinking of using my amd framework 13 for fedora and windows; it already has fedora.
For windows, instead of partitioning and incurring its risks with dual booting, I was thinking of just getting a different internal nvme, or to just put windows on the “Storage (2nd Gen) Expansion Card - 250GB” offering
So, I’m wondering about the actual performance and longevity compared to the usual sn7100 nvme drives that framework bundles as the internal drives.
If it is a micro sd card, then it would be awful. But for flash drives etc, I’m not sure on the advances and latest tech there. The marketing and order page does say:
All of this means that you can get the performance of an internal drive with the flexibility of an external one. Storage Expansion Cards are fast enough to install your operating system onto and you can boot from them too

But no mention on longevity. I got burned a lot in the past with raspis and failing sd cards, before realising they actually need high/max endurance sd cards.
i guess the spec you/we are looking for is TBW.
there is a reddit discussion about sdhc endurance and someone made some calculation estimate. if im getting it right, there are a few cards 128gb @ over 500tbw, which is just fantastic. current good class ssd endurance average is around 600tbw per 1tb capacity. on hdd, the parameter is tb load per year .
i was also looking for this parameter, the last i saw, its not stated. 
I’ve been thinking about getting one too, so did a bit of digging. This page says the second gen storage cards use sk hynix v6 nand. I’m no expert, but this seems like it is designed for low to mid level SSDs, not SD cards. For instance, this drive seems to use the same flash (but a different controller) and gets 150 TBW.
Cool, thank you both, so seems from some ai math its life should be anywhere from 50 to 4 years based on light to heavy usage.
Ordered two and will see how it goes, seems a competitively priced option for distro hopping! Much better overall than distro hopping via high/max endurance sd cards of the pi!
Should arrive in a few weeks I guess.
It’s not it’s an ssd with an usb controller.
HDDs don’t really care about writes (or at least didn’t use to, I could see hamr intorducing some write based wear factors). For hdds is is pretty much Power-on-hours, operating temperature and startups plus of course physical abuse.
We probably gotta de-rate it a bit in usb mode as it likely runs without trim which causes some write amplification.
