RAID Setup

Your solid state drives (SSDs) can be set up in RAID
mode (for increased performance or protection). Note
that setting up your solid state drives in RAID mode
needs to be done prior to installing the Windows OS.
Do not change the mode unless you intend to reinstall your
operating system, and make sure you back up all neces-
sary files and data before doing so.
To configure your RAID (Redundant Array of Indepen-
dent Disks) system in Striping (RAID 0) or Mirroring
(RAID 1) or Parity (RAID 5) mode (see
require two or three identical solid state drives.
Prepare the following before setting up your SSDs in
RAID mode:
• The Microsoft Windows 10 OS on a DVD or USB flash
drive.
• Two or three identical solid state drives.
• The Device Drivers & Utilities + User's Manual disc.
Note: All SSDs in a RAID should be identical (the same
size and brand) in order to prevent unexpected system be-
havior.

Description
Identical drives reading and writing data in par-
allel to increase performance. RAID 0 imple-
ments a striped disk array and the data is
broken into blocks and each block is written to
a separate drive.
Identical drives in a mirrored configuration
used to protect data. Should a drive that is
part of a mirrored array fail, the mirrored drive
(which contains identical data) will handle all
the data. When a new replacement drive is
installed, data to the new drive is rebuilt from
the mirrored drive to restore fault tolerance.
RAID 5 (Parity) is the most regularly used
secure RAID level. RAID 5 consists of block-
level striping with distributed parity so data
blocks are striped across the drives and parity
three
data is not written to a fixed drive, but is spread
Ds
across all drives. Using the parity data, the
computer can recalculate the data of one of
the other data blocks, should that data no lon-
ger be available. A RAID 5 array can withstand
a failure of a single drive so that no data is lost.
