fast on reads but slower than a single disk on writes. RAID 3 can be used with 3 or 4 disks and can
utilize hot spares.
3.3.2.4 RAID Level 5
RAID 5, also known as Block-Interleaved Distributed Parity, is the most popular RAID type due to its
optimal balance between reliability and performance. Data and parity information is subdivided and
distributed across all disks. RAID 5 can withstand the failure of any one drive. RAID 5 can be used with 3
or 4 disks and can utilize hot spares.
3.3.2.5 RAID Level 10 (1 + 0)
RAID 10 is a stripe of mirrors. In other words, there are two RAID 1 drive pairs that are combined into a
RAID 0. A single disk can be lost from each RAID 1 but it should be replaced as soon as possible. Data
protection is high, but transfer speeds are similar to RAID 1. The volume will appear as a single disk.
3.3.3 Power Loss Reconciliation
Power Loss Reconciliation is a means of detecting the damage done by a power failure during a write
operation and accelerating the recovery.
3.3.4 Load Balancing During Rebuilds
Enabling this feature will increase host responsiveness and will reduce rebuild speeds.
3.3.5 Enable Large Disks
This feature will allow you to create volumes larger than 2.2TB. Each OS behaves differently with large
volumes so please read the below sections to find out how your OS works with RTX400-QR.
Windows XP
Windows XP has a 2.2TB limit so this feature must not be selected when using Windows XP.
This is a limitation of the operating system but it will not affect the performance of RTX400-QR.
Windows Vista and Windows 7
Windows Vista and Windows 7 do not have a 2.2TB limit so long as the volume is initialized as a
GUID Partition Table (GPT). If you have a preconfigured unit then initializing a volume has
already been done. If you are installing your own drives then you’ll need to select GPT when
you’re formatting if you are using drives larger than 500GB (as shown below).
