Zfs Software Raid Vs Hardware Raid. A question often asked in the server industry is whats better software RAID or hardware RAID If you research this topic a lot of the information about RAID suggests that a hardware RAID card is preferable to using a Software RAID. Software RAID relies on UPS.
Ive done my proper research in terms of what hardware I will get and what features I want. Hi Im looking to buildbuy a NAS. Again its a waste of money and its 37 slower.
Software RAID on the other hand implements the various RAID levels in the kernel disk block device code and offers the cheapest possible solution as expensive disk controller cards or hot-swap chassis are not required.
In my opinion is that for most applications Software RAID is far better than hardware RAID. Hardware RAID handles its arrays independently from the host and it still presents the host with a single disk per RAID array. In my opinion is that for most applications Software RAID is far better than hardware RAID. It is used to improve disk IO performance and reliability of your server or workstation.
