Arco's RAID-based Storage Has No Smoke and Many Mirrors

A Different Take On RAID: DupliDisk And EzCopy

Arco leaves the task of finding an efficient and secure way to enhance drive subsystem performance to other companies.

The company's full name is, after all, Arco Data Protection Systems. It is no surprise, then, that both the EzCopy and the DupliDisk3 are based on RAID-1, which denotes a type of array in which the entire content of one drive is mirrored or duplicated onto another drive. Usually, this happens in real-time.

For example, a RAID controller recognizes the failure of a hard drive, alarms the mirroring software, which is ideally installed as well, and ensures continuous, problem-free and smooth operation of the system.

The DupliDisk3 is an add-in system for users who don't own a RAID controller but need or want the additional security offered by a RAID 1 setup - without having to reconfigure their Windows installation. More on this feature later in the article.

EzCopy uses similar RAID hardware, which is housed in an external, stand-alone case the size of a mini-barebone computer. It sports two drive bays for replicating the contents of one drive to another.
