I'm moving Unraid to my HP Gen8 Microserver and wondered if it's wise to use the MicroSD slot on the board as a cache disk?
I boot off USB and will be using the ODD bay for a 2.5" data disk if I can config this way.
I've installed a 32Gb class10 card and Unraid 6.2 sees it and will allow me to add it if I choose (I assume), but lets say I get a 128Gb MicroSD card and assign it to cache, rather than take up a sata channel. (128Gb is big enough for my cache needs)
I've searched but haven't seen anyone else comment they've done it, but I did see a post about the SD card becoming unusable if power suddenly removed from the server, put down to a bios fault which a UPS would cure).
So, can it be done and should it be done?
Any tales of success or disaster?
Cheers
