A fast iSCSI storage box made of left-over SATA+SAS SSDs

TrueNAS General

hello there, i have a bunch of SSDs “left over” and i would like to create one fast big volume with those to access from my windows 11 workstation via 25gbit network.

2 x 15.36TB SAS
8 x 4TB SATA

would it be possible to create two striped vdevs with those (VDEV1 SAS, VDEV2 SATA) and have them combined in one pool to create roughly ~55TiB of storage on a single “drive”?

this should easily saturate my network connection and basically feel like one big local drive when attached via iSCSI right? i have a backup of all the data on another NAS so no worries there, this should just provide the most amount of storage with the fastest speed.

i would use an AM4 platform with a 6C/12Thread Ryzen 5, 25gbit mellanox connect-x 4 and lsi 9305-16i hba as i have them already available, but could be changed to another platform if really needed.

any show stoppers i didnt think of? hardware potent enough?

would love to hear your thoughts before building.

Yes. But for iSCSI you’d rather make five 2-way mirrors than two vdevs (not sure what you were thinking of, but that could not have been a good idea). And load that plateform with RAM.
