Ideally SATA 6Gb/s drives should work with SATA II controllers. But remember it's always recommended to use drives in the Tested memory and hardware list. We do have some SATA 6Gb/s drives in the list.
The problem is that in my city it`s imposible tu find this drives... All the SATA are SATA II and they don`t sell HDD SATA II any more in my city and my enterprise don`t buy anything by internet.
So do anybody knows if two mirrowed HDs SATA III will work with the RAID SATA controller Intel® Embedded Server RAID Technology II of my S5520HC mother board that in theory only SATA II ?
Thank you for the help!!
Ok, I saw that you have SATA III drives in the list, but it´s impossible to buy this specific drives from my small city, and like I told you my entermprise don´t buy by internet.
The most similar drive that I can buy here is a Seagate ST500DM002 500Gbs, 7200rpm, SATA III
(I will buy 2 for the RAID 1)
So, do you know if two mirrowed HDs SATA III (don´t listed in the ' Tested memory and hardware list') will work with the RAID SATA controller Intel® Embedded Server RAID Technology II of my S5520HC mother board that in theory only SATA II ?
Not on the list means I can't tell you weather it will work or not, you need to test on your own. Ideally SATA III disks should work on SATA II ports, but it's highly recommended to use enterprise class hard drives in server environment. See Enterprise-class versus desktop-class hard drives comparison white paper.
