December 26, 20205 yr Hello People, all my drives are currently connected to the SATA ports on my motherboard but i just got an HBA from ebay to be exact i got an Intel RS3UC080J Which comes in JBOD mode by default. Is there anything i need to do before switching over to this HBA or can i just put everything together and swap the cables to the HBA and everything should be working as expected?

The product page for the J version also says RAID Support: None https://www.intel.com/content/www/us/en/products/servers/raid/storage-controllers/rs3uc080j.html https://www.intel.com/content/www/us/en/support/articles/000022720/server-products/raid-products.html So that means i should expect it to work just like a plain HBA?

Also this HBA doubled my write speeds when going from my cache to the array which proves my suspicion that this was another case of Intels bandwidth bottleneck to the chipset as on the H470 chipset they attached two m.2 4x slots and 5 SATA ports as well as all USB and network controllers via a single PCI-E 3.0 4x link to the CPU. Now that all my drives are attached via different PCI-E lanes this link from the Chipset is clear to be used basically only by my NVME SSD´s making everything much faster.
