3. Hardware Installation
This section provides information on installing drives.
Installing 2.5-inch Drives on the QDA-A2AR
The QDA-A2AR is compatible with 2.5-inch hard drives and solid-state drives.
Warning
• Installing a drive deletes all data on the drive, unless the drive adapter is in Individual
mode.
• Observe electrostatic discharge (ESD) procedures to avoid damage to components.
• Installing a QNAP drive adapter in another QNAP drive adapter is not supported.
1. Insert the drive into the slot.
2. Attach the screws.
Tip
Use a Philips #2 screwdriver.
Installing M.2 Solid-state Drives on the QDA-A2MAR
The QDA-A2MAR is compatible with M.2 2280 SATA solid-state drives.
Warning
• Only qualified personnel should perform the following steps. Failure to follow
instructions can result in serious injury or death.
• Observe electrostatic discharge (ESD) procedures to avoid damage to components.
QNAP Drive Adapter User Guide
Hardware Installation 6

• Installing a QNAP drive adapter in another QNAP drive adapter is not supported.
Note
• The QDA-A2MAR has two M.2 SSD slots. For a list of compatible M.2 SSDs, go to
https://www.qnap.com/compatibility.
• QNAP recommends installing thermal pads on the M.2 SSD controllers to enhance
cooling efficiency and ensure consistent performance.
1. Remove the cover.
a. Remove the screws.
b. Lift the cover.
Tip
Use a Phillips #1 screwdriver.
2. Install thermal pads on the system board.
a. Remove the protective film from the thermal pads.
b. Apply the thermal pads to the system board.
Note
Single-sided M.2 SSDs have components (e.g., controllers, flash ICs) mounted only on the top
side, and double-sided M.2 SSDs have components mounted on both sides. Apply two thermal
pads for single-sided M.2 SSDs and one thermal pad for double-sided M.2 SSDs.

4. RAID Configuration
This section provides information on configuring RAID settings.
Supported RAID Types
QNAP drive adapters support several RAID types.
Important
• When disks with different capacities are combined in one RAID group, all disks
function according to the capacity of the smallest disk.
• You can only use one disk type (HDD or SSD) in a RAID group. Combining different
types of disk in one RAID group is not supported.
RAID Type Number of Disks Description
JBOD (Just a Bunch
of Disks)
2 • JBOD combines disks together in a linear fashion. The
system writes data to a disk until it is full, and then
writes to the next disk.
• JBOD allows all of the disks capacity to be used, but
does not provide any disk failure protection or
performance benefits.
• Unless you have a specific reason to use JBOD, use
RAID 0 instead.
RAID 0 2 • Disks are combined together using striping.
• RAID 0 offers the fastest read/write speeds and uses
the total capacity of all the disks.
• RAID 0 provides no disk failure protection. This RAID
type must be paired with a data backup plan.
• RAID 0 is recommended for high performance
applications such as video editing.
RAID 1 2 • An identical copy of data is stored on two disks. If either
disk fails, data can still be read from the other disk.
• Half of the total disk capacity is lost, in return for a high
level of data protection.
• RAID 1 is recommended if you have two disks.
QNAP Drive Adapter User Guide
RAID Configuration 11

Mode Switch
You can configure RAID settings manually using the Mode switch on the inside panel of the drive adapter by
moving the switches to the corresponding positions as illustrated above.
Important
• You can only use one disk type (HDD or SSD) in a RAID group. Combining different
types of disk in one RAID group is not supported.
• If disks with different capacities are combined in one RAID group, all disks function
according to the capacity of the smallest disk.
Configuration Description
Individual Each disk is identified as a separate drive. The disks are not combined into a
single volume or RAID group.
This configuration is also known as a port multiplier.
Note
• QNAP NAS devices do not support Individual mode for
QNAP drive adapters.
• Your system's SATA controller must support port multiplier
in order for both drives to be detected in Individual mode.
Contact your system provider to ensure that your SATA
controller is updated with the latest drivers.
• JBOD
• RAID 0
• RAID 1 (default
factory setting)
QNAP drive adapters provide hardware RAID support for these RAID types.
For details, see Supported RAID Types.
