Build Description
10X Random recycled HDDs a DJ friend was getting rid of/clearing out. Ubuntu 20.04 LTS Desktop w/ZFS Raidz, LZ4 block level compression, RAID 0 SSD L2 ARC and Logs caches. SuperMicro x10slh-n6-st031 Motherboard w/4x10GbE bonded network adapter, quad core 3.4Ghz Xeon, 32GB DDR3 1600Mhz, 128GB SSD RAID1 mirror for OS partitions. Over 28TB basic capacity w/RAIDz single drive fault tolerance. Each drive broken into a multiple of 1.35TB partition slices across 10 SATA 3 HDDS, with ZFS deduplication enabled and LZ4 compression, this NAS should be able to serve over 50TB of files for my studio before filling up.
Favorite Feature
Aside from being a massive budget NAS, the L2 ARC and ZFS Logs SSD caches basically allow the machine to write instantly with a pretty efficient and intelligent read cache. This eliminates HDD seek times across the 10 spindles to a minimum for reads that aren't in cache already, and eliminates them for writes. Very fast...
