Our LenovoEMC px4-300d has existing 2 x HDD in RAID 1 configuration. The existing HDD is 2TB 3.5" with P/N: H3U20006472S (Hitachi brand) and has rotational speed of 7200RPM and 64mb buffer rate.
I would like to add 2 more drives (total of 4) and make it in RAID 5 configuration. That way, to maximize the capacity.
I can't find the same model (Hitachi) of HDD. Therefore, I would like to know if I can use different brand of HDD and mix it as long it has the same Rotational Speed (RPM) and Buffer Rate.
Please advise if there won't be an issue if I will use the HDD model below:
Seagate Barracuda 2TB ST2000DM006 7200rpm 64mb Sata
