請問可否mix 12GB/s SAS及 6GB/s SATA 行raid?

現時有4隻Helium 10TB 行raid-6 (另有２隻off-line做backup), 見網上12GB/s SAS 平, 想買數隻逐步換入, 可以嗎?

Yes, you can mix SAS HDD of different speeds. However, both will operate a lower common speed as negotiated by the controller.

Thanks. But I mean mixing SATA hard drives with SAS hard drives in the same raid-6 setup (say, 2 SATA and 2 SAS).

While you can use a combination of SAS and SATA hard drives running on the same controller, you cannot mix them in the same array.
