Product Description:
Introducing the MB561US-4S-1 Quad Bay SATA External Enclosure featuring USB and eSATA Port Multiplier (eSATA Port Multiplier Card Required), and newly added, User Defined Fan Settings with Smart Cooling Technology.

We have taken our tried and true multibay product and added new features to further enhance your complete storage experience. Using all the features that you know and love, we have upgraded the 80mm cooling fan to allow the user to choose the speed of the fan, or to select “auto” so that the fan adjusts its speed using our Smart Cooling Technology. Our auto function determines the temperature of your drives, and changes its RPM according to the airflow and cooling demand. This results in decreased power consumption, an increased lifespan for your fan, and unnecessary excess noise. Along with the auto function, the user can also choose a high setting, best used for intense applications such as home server use, or a low setting, best used with lighter work loads such as hourly back ups or network attached storage (NAS).

The MB561US-4S-1 still includes all the standard features. A single e-SATA port provides a direct, single connection and flexible options for advanced users. With a port multiplier e-SATA connection, you can either connect to a port multiplier JBOD adapter to access four drives via one e-SATA connection, or connect to a port multiplier RAID controller card. This is convenient for those who do video editing through Mac or PC and wants configurations of RAID 5 settings for increased storage capacities and blazing fast transfer speeds.

The additional USB connection is for quick hook up to any computer system (especially laptops), which allow users to access up to four drives at the same time, and best of all there’s no driver installation required. This allows users to organize their music, photos, and work data under one enclosure, making it perfect for backup applications.

The enclosure takes up to four SATA drives. To power the enclosure, it uses a direct AC outlet, perfect to use it anywhere without having to deal with any adapters. The lightweight construction design protects hard drives with a layer of solid aluminum. It has a detachable 80mm ball bearing rear fan with 3 speed settings, and uses a built-in fan-less power supply, making it a quiet device. The four hot-swappable drive trays offer great freedom of choice in expanding your storage solution and multi-drive exchangeability for easy maintenance.

Add-on data/ media files storage to laptops, graphics & video editing, interchange of data between corporate/school/home workstations, data file backups.
