NormanB Posted March 21, 2022 Share Posted March 21, 2022 Is it advisable to mix storage types in cache pools. For example, can/should you use an M2 NVME and an M2 SATA drive as redundant pairs in the same pool? I have a limited number of SATA ports on my motherboard (Dell T3600) and need to make use of everything I can. So I have a PCIe card with that holds an NVME drive and also powers an M2 SATA. The drives are the same size and I would like to use them together in the same cache pool. I also have an H310 flashed to IT mode that has capacity, but I've heard it's not ideal to put solid state devices on those controllers. Quote Link to comment

NormanB Posted March 21, 2022 Author Share Posted March 21, 2022 Thank you very much. On a related note, is it true you shouldn't run your cache SSD's off of the main HBA along with your pool storage HHD's? Quote Link to comment
JorgeB Posted March 22, 2022 Share Posted March 22, 2022 Depends on the HBA and devices, some HBA or HBA/SSD combinations don't support TRIM, if it does there's no problem. Quote Link to comment
