Do I have data redundancy in RAID 0 mode?

No. While RAID 0 mode gives you more disk space, it will provide no data redundancy. Please, configure your DriveStation Quad for RAID 5 or RAID 10 to keep your data most secure.

Do I need any software to use my MiniStation or DriveStation?

Buffalo external USB storage devices do not require any software to use as an external hard drive in Windows or Mac. The Buffalo Tools suite of software is optional software that provides performance enhancing technologies, backup, and encryption amongst other features. To use these features, software components must be used.

Do I need to format my DriveStation or MiniStation before I can use it?

All Buffalo DriveStation and MiniStation products come preformatted and are ready to use. It can also be reformatted to NTFS or HFS+ easily from any Windows® or Mac computer.

What capacity will the device have in different RAID modes?

The DriveStation Quad supports RAID0, RAID5 and RAID 10. In RAID 0, all hard drives are combined to provide maximum storage equivalent to the stated capacity of the device. However, in RAID 0 there is no data redundancy. RAID 5 provides data redundancy by using parity information on all drives and therefore provides 75% of the stated capacity (the equivalent of one hard drive is used for data redundancy). Finally, RAID 10 is available if you would like to combine the drives into a set of striped mirrors. In RAID 10, the volume is equal to 50% the advertised capacity.
