The 3 regular HDDs are tied to the mainboard sata controllers, along with the the BluRay burner, the case's built in drop-in 3.5/2.5 HDD/SSD socket and 1 x eSata port and NvME drive. The SAS2 controller is dedicated to the 8 x SSDs. The case is a Thermaltake Chaser Mk-1, lots of room for cooling, liquid and air, room for internal enclosures, etc... The SAS2 2008 Falcon started life as a 9211-8i before the firmware update/conversion to JBOD only, with BIOS disabled. I use it as my Gaming Rig, VM Server Rig, Media Storage Rig.

I probably will end up breaking them up and using something like rsync / or the old Microsoft SyncToy to synchronize directories. I also have an old LG nas with dual mirrored 6TB Drives. Some of my kit is upwards of 5 to 6 years old now, the 8 port SAS/SATA controlller is amongst the oldest. Intel Core i7-4790k @ 4.00Ghz, 32GB Corsair Extreme Profile 1, Gigabyte GA-Z97X-Gaming 7 Motherboard, LSI SAS2 2008 Falcon in JBOD mode, 2 x 4 Pair Breakout cables, tied to IcyDock 8 Bay SSD Hot Swap, 8 x Samsung 850/860 500GB SSDS, 1 x Samsung 960 Evo NvME, 2 x 8TB Seagate HDDs, 1x2TB Seagate HDD in 3 Bay Hot Swap Enclosure, AMD Radeon R9 390 8GB Video Card, Samsung CHG9_C49HG9xDM (3840 x 1080 in one 49" monitor)

Indeed I did Now if only the performance of the SSD side of the pool didn't tank to the performance level of the HDD archive disks. Tried with read-striping enabled and disabled, still seems to want to read from HDDs as much as the SSDs.

You are correct, it would not allow it. So sticking with 3x duplication, 1 x for each sub-pool. Thanks again for your time.

I modified the lines Pool 2: A 4TB volume from HDD1 + a 4TB volume from HDD2. Enable 2x pool duplication, Real Time Duplication, and Read Striping. Pool 3: The other 4TB volume from HDD1 + the other 4TB volume from HDD2. Enable 2x pool duplication, Real Time Duplication, and Read Striping. Reasoning that with that layout, one drive failure takes out both. Split each in half, both halves of each drive pooled together. D1P1 + D1P2 = Pool2 D2P1 + D2P2 = Pool3

Ahh, the old re-measure seems to have cleared things up. I was wondering why it kept showing my SSDs as being larger than they were.

In the process of breaking the pool into the pieces as suggested, first step was to disable duplication. However, even with all duplication disabled, I'm still showing about 300GB worth of duplicated files. What steps should be taken to clear out the duplication stragglers?

TYVM!

Brand new to Drivepool, looks like lots of features and options, myriad of possibilities, a bit overwhelming to a new user. Running an 8 x 500GB Samsung 860 with 2 x Seagate 8TB HDDs. What I want to do is have all source files on the SSDs, and then 2 replicas of each source file on each of the 8TB HDDs. Yes, it is probably overkill having 5 total copies of each file, but that is what I'm shooting for. How would I best define this? Plugins? Balancer settings? Thanks!

And if the cloud drive is part of a drive-pool as an archive drive?
