I want to speed up a setup of 2 existing mirrored magnetic HDs. They currently are in a NAS but I plan to add them locally to the system and use Storage Spaces in mirror mode on them to get the same safety with perhaps a small performance penalty.

Can I extend the array with a single SSD for caching and gain a reasonable amount of performance?

Also, is this somehow fault-tolerant, i. e. if the SSD dies, does the whole (mirrored) array still work and have complete and consistent data and just is a little slower till I add a new SSD as cache?

Or do I have to add 2 SSDs in mirror mode and use tiered storage?

This will not work as the resiliency setting mirror will fail to apply even with tiered storage. You require two SSD's. with that said, you get full capacity. annoying i know.

New-VirtualDisk –StoragePoolFriendlyName "Pool" –FriendlyName "SSHD" –StorageTiers @($ssd_tier, $hdd_tier) –StorageTierSizes @(230GB, 16764GB) –ResiliencySettingName Mirror –WriteCacheSize 100GB
