Is it a good idea to get a 400 gig micro sd card for a laptop instead of paying 600 dollars for another 500 gigs on the ssd

I want to get a surface book 2 or a surface pro with 256 or 500 gigs of internall ssd. But the price increase is 600 cad for that ssd to get 500 gigs more. Is it even very fast?

Or I could get a switch compatible memory card incase I want to get a switch and just use an external hdd for the surface at home. I think I could get by on 256 gigs if I really forced myself. If I install software and store the software on a external hdd that I dont bring with me. Can I rehook it later and use that software? How does that work.

Also. do the adapters to sd card size, does it matter if its a larger size does it slow the speed?

An SD card will be MUCH slower than a slow SSD.
SSD's get much closer to their rated maximums than SD cards.
That SD is rated at 100Mb/s. You'd be lucky to get half of that, whereas a decent nvme SSD will get at least 2,500Mb/s of it's 3,200.
Even if that SD gets its full 100, it's 25x slower.

Memory cards are also less reliable than proper storage drives as they can (and do) fail with no prior warning because they have no built-in health monitoring (SMART).

Both HDDs and SSDs incorporate SMART.
