I have had good luck with using the linux built in raid. For raid-1 the mdadm tools should be just as fast as any raid card that you can get on a budget. Raid-3 and above do better with the caching on higher end raid cards but then your likely out of the $250 range. The important thing it to monitor the raid status. If a drive fails and your not checking the status you will only find out about the first drive failure when the second one fails and your filesystem is unrecoverable. I have seen this happen with raid-cards and also with software raid. On 2022-12-01 14:00, Aurelian Melinte via talk wrote:
Hello,
I am looking to get a RAID card to put my SATA HDDs in a mirror. Has to be hardware RAID for that particular machine which is quite old. Can anyone please recommend a reliable one, $250 or less?
Thanks!
