Over the weekend, I found out that the 3TB drives I’d been using in a RAID 1 at home have had a 94% failure rate from Backblaze. So, you know, good job to myself for finding the news a year after it was released. I ended up buying 4x5TB Seagate drives at they represented the lowest cost per usable GB out of the field. I wanted to use a Storage Space, but mixing SATA and USB 3.0 in a Storage Space led to some abysmal write speeds. So I broke my 3TB mirror, put one of them where my optical drive normally is, and moved all 4 5TB drives into the case, in a RAID 10. That takes me from 5TB usable (2x1TB RAID 0, 2x3TB RAID 1) to 10TB usable, so it’s going to be nearly halfway full out the gate. Here’s hoping there are some higher densities on the horizon before I fill up the other half.
Copying 5TB of files blows. But it’s gotta get done, and it was a good opportunity to reorganize anyway.
