Depends on the technology of the card itself.
I've personally been using Transcend Ultimate 633x 64GB card on my Jolla1, and it handles swap pretty well.

- it uses dynamic wear leveling, to spread the writes accross more erase groups, delying the dying.
- it uses static wear leveling to also occasionally re-write old data to avoid it decaying over time (remember Samsung's non-pro 840 SSD, back with the old firmware ?)
- has ECC and is much more resilient.

I second that, but only on some high quality microSD card that can survive the load.

Out of curiosity, what problems are you experiencing ?

hope in the next dalvik (or probably ART) release that will be fixed.
Currently, we're stuck with Alien-Dalvik. We won't see anything at least not before Sailfish 3.

According to some threads on TJC, some cards aren't even physically recognized by the kernel's mmc driver.
(Someboy had problem with a Saumsung EVO (non plus) 128GB)
Apparently, it's a known kernel problem (should be eventually solved in some future upgrade).

That's in addition of you needing to either reformat from exFAT into something slightly more cross platform (e.g.: FAT32), or installing exFAT fuse drivers.

Before getting to the exFAT problem, as mentionned above, check that the kernel at least sees the MMC device itself :

after loading the card holder in the phone, do you see a "/dev/mmcblk1" device appearing (external slot) ? or do you only see "/dev/mmblk0p??" devices (internal flash).

What does "blkid /dev/mmcblk1p1" say ? (run as root with "devel-su" ?)

Try: "mount.exfat-fuse /dev/mmcblk1p1 /media/sdcard"

To force your system to use the correct FUSE helper.
