can you run raid 5 with Ubuntu 22.04 on this setup?
10Gtek M.2 (M Key) connected to a 6xSATA adapter via SATA3.0, no RAID enabled, designed for desktop PC support SSDs and HDDs. You can place the first SSD in slot 1 with its heatsink, while the sixth port is meant for a 5.25" Blu-ray burner.
I own a 2.5" SSD drive and have a spare low-profile cable. I also possess an ORICO M.2 PCIe RAID-PM2TS6 adapter.
These are my current components: RAID 5 + burner version 1. The NVMe drives are mounted in slot 1, with the 10Gtek M.2 adapter in the rear slot.
I’d like to use the NVMe drive in slot 1 as a cache for the RAID array. Would I be able to reconfigure for more storage if I connect the burner to a standard SATA port instead?
If Ubuntu 22.04 supports this during installation, would it be preferable? Otherwise, I’d stick with RAID 5 and consider using Btrfs with compress=zstd:10 if possible.
Currently, I aim for about 6TB total storage—enough for all my operating systems, main drives, plus ample space for audio, photos, videos, and downloads. The 2.5TB drive will handle games, renders, and media, while the extra 4TB should comfortably cover everything.
I'd implement software raid using ZFS. BTRFS continues to have many problems with raid 5/6, making ZFS a more logical choice. ZFS is usually superior to hardware raid overall, so avoid using any raid capabilities on those cards. Additionally, you should store an SSD array alongside another SSD. Don't waste effort caching drive types that are identical—like combining an HDD array with an SSD or an NAND array with Optane.
For Ubuntu Server 22.04, you can set up RAID 5 during installation and include the Compress=zstd:10 option in the compression settings. This approach works well if you're comfortable with the installation process.
