XtendLan XL-RAID-SATA-USB, User Manual

Page: 12 / 20

2.2 Precautions and Requirements
1. The XL-RAID-SATA-USB can be used with two hard disks that are of different models and storage
capacities initially. However, for improved performance, we recommend that both disks should have
the same specifications and capacity from the same manufacturer. It is also necessary that the
backup drive be the same or bigger in capacity than the source drive under the RAID1 model.
2. Please ensure that the two hard disks used contain no bad tracks. This avoids system crash or data
loss in the event that one hard disk malfunctions.
3. RAID0 mode offers improved data transfer performance and the full use of both hard disks as one
large capacity disk. It does not offer data mirroring, however so, if one hard disk is damaged, all data
will be lost.
4. We recommend that you decide whether to use the product in RAID0 or RAID1 (default value) mode
before it begins initial operation. Changing the RAID mode at a later date will result in the complete
loss of all data on the hard disks.
2.3 Hardware Installation

Step 2 Remove the Tray and install your hard disk onto the tray. Make sure the hard disk secure
screws are fastened to avoid unnecessary movements to the hard disk.
