https://community.hpe.com/t5/disk/mixed-manufacturer-drives-in-array/m-p/2517514#M721 I have hard drives from different manufacturers with different geometries and firmware, and I would like to know what performance issues or problems there might be in mixing them in the same array with a Smart Array 5300 controller. I would also like to know who manufactured the following drives: <BR />Compaq part no. 176496-B21 firmware BDC4 <BR />Compaq part no. 176493-003 firmware 3B06 <BR />If one of these is smaller and I use it to replace the larger one in an array, I feel there is a potential for loss of the integrity of the array. At the very least I believe I am losing the full potential of my array.
