https://community.hpe.com/t5/disk/ultra-2-and-ultra-3-array-configuration/m-p/2578686#M1292 Hi all, I have a raidset consisting of Ultra 3 drives. I'd like to add an online spare, which is an Ultra 2 drive. Would the mixing of the drives result in the whole array running at Ultra 2 speeds or would this only occur when the online spare is online? Thanks.

Then it will run at an Ultra2 speed. Thu, 01 Nov 2001 00:00:00 GMT https://community.hpe.com/t5/disk/ultra-2-and-ultra-3-array-configuration/m-p/2578687#M1293 Mark Cloutier 2001-11-01T00:00:00Z
