This happened something like a decade ago. BIOS systems were updated along with procedures. Be sure the partitioning is done during the Windows install or else you learn why.
Fresh install of windows on brand new drives.
Setup the raid before installing windows, setup 3 x 1TB SSDs in a raid0 using the bios.
After installing windows, it's showing the partition as 1.98GB.
Shouldn't it be closer to 3TB? What could I have done wrong?
