Silverstore Supports The Following Raid Levels - Freecom SILVER STORE 2-DRIVE NAS User Manual

EN

SilverStore supports the following RAID levels:

• Stripe (RAID 0) - All data are distributed evenly to all existing drives. The two drives
work in unison to maximize system performance. However, RAID 0 has high risks of
data security. If one drive fails then all data in both drives are lost.
• Mirror (RAID 1) - Two hard drives are required. Data written to one hard drive is
simultaneously duplicated to another hard drive. If one drive fails, the other drive
continues to function as single drive until the failed drive is replaced. To create a mirror
you must select unallocated space on another hard drive and the unallocated space
must be the same size or larger than the source drive you want to mirror. Data on a
mirrored drive is secured, if one hard drive fails, SilverStore administers a warning and
the failed drive must be replaced immediately.
• Span - Also known as JBOD (Just a Bunch of Drives). Two hard drives are required. Several
hard drives are configured as a single hard disk expanding the capacity of the hard
drive and results in a useable total capacity. However, span does not increase system
performance or data security.
