XtendLan XL-RAID-SATA-USB User Manual - 2.2 Precautions

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

Step 2    Remove the Tray and install your hard disk onto the tray. Make sure the hard disk secure
