Select the Bit Rot Protection (Copy-on-write) check box to enable bit
rot protection. For information, see Bit Rot Protection on page 62.
Enabling bit rot protection also enables copy-on-write. Over time,
copy-on-write increases disk fragmentation.

Select the Compression check box to enable data compression.
Compression saves storage space and increases the speed of data
transfers, but the compression and decompression processes require
additional resources. By default, the Compression check box is cleared.
Compression
Select the Auto-Defrag check box to enable automatic defragmentation.
When auto-defrag is on, after writing to a file, ReadyNAS OS consolidates
and rewrites portions of the file to reduce fragmentation.This reduces
or eliminates the need to periodically defragment the entire volume,
but because it occurs after every write it, can impact performance if a
file is written to very frequently. Examples of applications that make many
writes to the same file are databases, virtual machine images, and iSCSI
LUNs. If the share or LUN is used for these and similar applications,
auto-defrag might not be a good solution.
