Discrepancy in Reported and Actual Size Capacity

Q: I have a 750GB HDD, why does the RAID only recognize the HDD available space as less than

750GB?

A: Many customers are confused by their host system when it reports a discrepancy between

reported capacity and actual capacity. Several factors can come into play when your host

system views and reports the capacity of a hard drive. There are actually two different

numbering systems used to express units of storage capacity:

Binary: provides that a kilobyte is equal to 1024 bytes; and

Decimal: provides that a kilobyte is equal to 1000 bytes.

Capacity Disclaimer

Actual accessible hard drive capacity will indicate up to 10% lower than stated under different

Operating Systems and formatting.

The storage volume is measured in total bytes before formatting. References to round

numbers of gigabytes or terabytes are an approximation only. For example, a disk drive labeled

as having 500GB (gigabytes) has space for approximately 500,000,000,000 bytes before

formatting. After formatting, the drive capacity is reduced by about 5% to 10% depending on

the operating system and formatting used.

RAID 0

Q: If I have 4 HDDs, can I create two sets of storage units by using RAID 0 Mode?

A: The Arcticroc 4-Bay is designed to support 4 HDDs, but it cannot create or support two sets

of storage units under RAID 0 mode.

Rebuild

Q: Does the RAID have to be connected to the host computer when it is in Rebuild Mode?

A: No. The RAID can support off-line Rebuild, which means it can perform the Rebuild function

without being connected to a host computer.
