speedcoaster Posted December 22, 2020 Share Posted December 22, 2020 Hey Everyone, I'm planning to upgrade my storage with a cheap SAS Drive Enclosure (the HP QR491A). Working with SAS expansion enclosures is new to me and I want to make sure that I understand everything right before purchasing it: - This enclosure should work fine with normal 3.5" SATA HDDs (like Seagate Ironwolfs) - I can connect the enclosure to my existing HBA with an 2x SFF-8087 -> 2 x SFF-8088 adapter (My HBA is a LSI 9211-8I and uses a LSI SAS2008-> this one exactly https://www.amazon.de/gp/product/B01M2AC40Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ) - The disks in the enclosure will show up as individual disks and not as a combined RAID disk I already have about 14 Disks in use (not counting parity or cache drives), but my Fantec case is really poor quality and I have lots of problems with backplane connectivity, so I plan to put nearly all my existing disks in the HP QR491A. Thanks in advance and joyfull holidays everyone Quote Link to comment

Paul_Ber Posted December 24, 2020 Share Posted December 24, 2020 Put your SSDs on the Motherboard SATA ports. Someone said the LSI HBA cards cannot do TRIM on SSDs. Quote Link to comment
speedcoaster Posted December 24, 2020 Author Share Posted December 24, 2020 Thanks for the advice, I plan to keep the SSDs and the parity drives in the main case and connect them directly to the motherboard. Maybe also some data drives, because in the long run I will max out the number of data drives Unraid supports. Quote Link to comment
kayjay010101 Posted May 14, 2021 Share Posted May 14, 2021 Did you end up going for the M6720? How is it in regards to unRAID and (presumably) non-HP drives? Quote Link to comment
speedcoaster Posted May 14, 2021 Author Share Posted May 14, 2021 Oh right, sorry for not updating. No, i didn't find any drive caddys for a reasonable price. I ended up buying a used Supermicro 847E26-RJBOD1 for around 900€. It's like new and works great with Unraid, my HBA and all my drives (Seagate, WD and Toshiba). Quote Link to comment
