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.
Disk performance
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 |
| WD10j31x | 2.5" SSHD | SATA | 89.8 | 17.31 |
| WD2002FAEX | 3.5" HDD | SATA | 124.2 | 12.78 |
| WD4000F9YZ | 3.5" HDD | SATA | 137.3 | 14.32 |
| Seagate expansion 3TB | 3.5" HDD | USB 3 | 158.8 | 17.51 |
| Seagate expansion 2TB | 3.5" HDD | USB 3 | 139.6 | 15.42 |
