7.4 RAID system
The device supports two separate SSD mass storage devices that can be used together with the help of
RAID technology (RAID = redundant array of independent disks).
To use this function, two type
M.2 2242 Key M
SSD cards with a
SATA
interface are required. NVMe
cards with a PCIe interface cannot be used.
Supported options:
•
RAID level 0 striping
: this RAID variant is recommended when a large data storage system with
high data access speeds is required. Since the data are not stored redundantly, this level is only
recommended if data loss will not result in serious consequences, e.g. because the data can be
recovered easily if a storage medium fails.
•
RAID level 1 mirroring
: both mass storage devices redundantly store the same data in this case. If
a mass storage device fails, usually no data is lost and the defective mass storage device can easily
be replaced. The total storage size corresponds to the smallest of the individual storage devices
used.
7.5 WLAN/Wi-Fi
This optional function uses the resources provided by the respective operating system and an internal
antenna.
7.6 Bluetooth™
Devices with WLAN also have Bluetooth, which allows e.g. the connection of a mouse or headphones.
This function uses the resources provided by the respective operating system and an internal antenna.
The desired RAID level must be specified when placing the order.
