my server now has 8TB of storage

it’s btrfs RAID-1 on two second-hand Seagate Enterprise Capacity (ST8000NM0045-1RL112) drives that are over 6 years old so I’m not sure how long they will last

also they’ve got 4k logical sector sizes so I don’t think SeaBIOS will be able to boot from them (but I don’t need that anyway)

one of those drives is now making a buzzing sound that lasts about a second then stops for a few seconds. I don't think it's supposed to do that
