Hi,<br />
<br />
I am planning to get 2 x SAS 256GB (RAID1) and 2 x SATA HDD 1TB (RAID1). <br />
<br />
SAS disks will be used for OS including hyper-v VM OS. 1TB SATA disk will be used for storing data on within the OS.<br />
<br />
Is it okay to mix both and still be able to use under same OS?

Hi,

I am planning to get 2 x SAS 256GB (RAID1) and 2 x SATA HDD 1TB (RAID1). 

SAS disks will be used for OS including hyper-v VM OS. 1TB SATA disk will be used for storing data on within the OS.

Is it okay to mix both and still be able to use under same OS?

SAS and SATA mix on same controller

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
