RAID Initialization Time
We used eight Seagate Savvio 10K.2 hard drives to determine the time needed by the controllers to create a RAID 5 or RAID 6 array.
|Controller||RAID 5||RAID 6|
|Adaptec RAID 3805||1 hour 12 minutes||1 hour 2 minutes|
|ICP 5085BL||57 minutes||57 minutes|
|Raidcore RC5252-8||2 hours 42 minutes|
Clearly, the cards with the faster XOR accelerators complete the array creation task quickest. However, all products support background initialization, which reduces available performance but lets you start using the array right away.
