The advantage of software raid is portability (i.e., you can plug your disks into ANY controller and access your array rather than being stuck buying a new card if the card burns out), and cost (i.e., you don't need to buy a raid card for software raid).įAKERAID (which is a hardware device that pretends to be hardware raid when the raid function is actually entirely within software) is complete crap. The advantage of hardware raid is performance, plain and simple. Yes, mdraid is happy to allow you to add/remove volumes from the array and/or rebuild the array entirely online with no downtime just like hardware raid. Hardware raid does NOT give you any hotswap and/or online array rebuilding that doesn't ALSO exist within mdraid. Any kind of parity-raid (raid 5, 6, etc.) will ALWAYS be slower in software raid than in hardware raid, especially when the host CPU is under load. Software raid can NEVER be *faster* (it is at best AS fast for stupid raid types, like striping) than hardware raid unless those who implemented the hardware raid were a bunch of rabid chimps on acid. This marks a return to using block mode in Go-AsciiSprite, and it’s the first time I’ve ever used one for doing a doodle.The first project I did with block mode was Text Invaders, and I also put together a demo for something that resembled Super Mario Bros, but I was never really happy with the way either worked.
