Increased storage capacity
I purchased 3 WD Red 8TB disks to put into the Drobo (its used to backup the storage server). This brings the Drobo up to 16TB of usable space.
At the same time I purchased 3 Toshiba 8TB disks to put in the storage server. I have a new disk controller on order that supports up to 8 drives and will swap the drives around when installing it. The idea is to have a vdev of 3 drives in raidz1 which will give single drive redundancy and more than 16TB of disk space due to compression. I can then add more drives as needed.
While doing some online research I came across the gnome-disk-utility that can benchmark disk performance so I let it loose on a few different drives that I have. Interestingly the Seagate expansion drives had a high transfer speed and the SSHD came in the slowest for transfer speed and 2nd slowest for seek time. I haven't benchmarked the NVMe SSD yet.
|Drive model||Type||Interface||Ave read (MB/sec)||Ave seek (msec)|
|Samsung 850 Pro||2.5" SSD||SATA||521.7||0.05|
|Seagate expansion 3TB||3.5" HDD||USB 3||158.8||17.51|
|Seagate expansion 2TB||3.5" HDD||USB 3||139.6||15.42|
