Using your LinkStation
LinkStation User Manual 92
• RAID 5 mode (4 hard drives)
RAID 5 mode (4 hard drives) is available for LinkStation models with 4 hard drives. Uses 4 hard drives
as one array. It generates parity during writes, so access speeds are slower than other RAID modes.
Usable space is the sum of 3 hard drives’ space. If one hard drive in the array is damaged, you can
recover data by replacing the hard drive. You cannot recover data if 2 or more drives are damaged.
• RAID 5 mode (3 hard drives)
RAID 5 mode (3 hard drives) is available for LinkStation models with more than 3 hard drives.
Uses 3 hard drives as one array. It generates parity during writes, so access speeds are slower than
other RAID modes. Usable space is the sum of 2 hard drives’ space. If one hard drive in the array is
damaged, you can recover data by replacing the hard drive. You cannot recover data if 2 or more
drives are damaged.
• RAID 10 mode
RAID 10 mode is available for LinkStation models with 4 hard drives. RAID 10 combines 4 hard drives
into a single array. Usable space is the sum of the capacity of 2 hard drives. Data is written quickly
and access speed is faster than other RAID modes except for RAID 0. Since the same data is written
to 2 hard drives at the same time, if drive in a pair (1-2 or 3-4) is damaged, data can be recovered by
replacing the damaged hard drive. If both 1-2 or 3-4 hard drives are damaged, you cannot recover
data.
