The performance problems and I/O errors went away. After moving data off the home server, I removed the drives with the incorrect model numbers and enabled PerfectDisk. Unfortunately, about half of the drives I bought, including the 2TB drive, were not the right models. Further research found that there are only two good WD Green model numbers: However, doing so I ran into problems with PerfectDisk and defragmentation where the system would hang or blue screen, leaving errors in the event log around the storage or Marvell drivers causing issues. I added a bunch of WD Green 1TB drives and one WD Green 2TB drive. In general, I’ve found these drives to be horrible performers. I stumbled upon WD Green hard drives and they appeared to not only be affordable but also provide power saving benefits.īad, bad news. I ended up putting the three 1TB drives into a RAID 5 configuration to balance storage and resilience. You can’t allocate RAID disks into a Storage Space - you have to use RAID instead. This makes it incompatible with Storage Spaces. I discovered while setting up Windows Server 2012 with Windows Server Essentials that the OS actually sees the drives as a RAID-controlled array to be provisioned, not as separate SATA disks.
