You can start your RAID Rack with just one hard drive and expand by adding more hard drives as your storage requirement grows. You have a choice of models with Port Multipliers or with simple direct drive connection via eSATA or mini SAS cables. Drives are added or removed directly like tape cartridges. The RAID Rack is multi-OS compatible depending on the host controller.
One of the new 1U RAID Rack models is the R1ESU3F that comes integrated with a hardware Port Multiplier with RAID accelerator for high performance. All four drives connect to the system via a single eSATA, USB 3.0 or Firewire 800/400 cable. RAID can be configured via a set of switches, accessible at the back, or via software utility. MSRP for this model is $359
Another model is the R1MSAS, which supports connecting all four drives via a single mini SAS cable to a system equipped with a mini SAS connector (SFF-8088). The four drives can be used as independent drives or set to RAID via the RAID utility of the OS or the attached controller. Mini SAS cable connection can be as long as 10 feet, making this model an ideal solution that requires direct attached storage with long cable connection. MSRP for this model is $299
