RAID hard drive maximum and associated storage controller
options
This section lists the maximum number of hard drives supported on HP workstations according to RAID
configuration and storage controller options.
NOTE: This section applies to internal workstation configurations that do not use add-in cards and external
enclosures.
Maximum of two 2.5 inch hard drives
●
● Two M.2 slots

Supported RAID configurations

The following RAID configurations are supported:
Configuration
RAID 0
Integrated striped disk
array
RAID 1
Mirrored disk array

Configuring Intel SATA RAID

This section describes how to use Intel
volumes.
NOTE: These instructions apply to Windows-based systems.
You can create a RAID array from two 2.5" drives attached to SATA ports, and/or two M.2 SSDs connected to M.
2 slots. RAID cannot be created across controllers, so 2.5" SATA drives cannot be configured with M.2 SSDs.
RAID must be enabled (Advanced > System Options > Configure Storage Controller for RAID is selected) to
set up any RST RAID.
When the Option ROM Launch Policy is set to All Legacy, the Intel SATA option ROM configuration utility runs
during POST if two SATA drives are attached. If only one drive is attached, the Intel option ROM configuration
utility does not run unless the drive contains RAID metadata indicating a failed RAID condition. Legacy Option
ROM cannot be used to configure RAID for M.2 SSDs.

RAID configuration details
Description
● Requires a minimum of two drives.
● Provides improved I/O performance.
● Provides no fault tolerance.
Loses all data if any disk in the array fails.
●
● Increases disk performance.
Supports a minimum of two drives.
●
● Provides 100% redundancy: all data from one drive
is duplicated on a second drive.
● Recovers from a single-drive failure.
● Serves as a good entry-level redundant system.
