The MB561U3S-4S R1 is designed for those in need of large data storage with a small footprint and supreme build quality. The USB 3.0 with UASP support increases the speed of transferring or rendering large files while accessing up to four individual drives and is backward compatible with USB 2.0. The eSATA interface delivers fast SATA III speed, supports eSATA port-multiplier function which allows you to access four individual drives via single eSATA connection (host requires eSATA port-multiplier support),and is compatible with most of RAID controller card with eSATA port-multiplier interface. The 4 bay capacities give you enough room to optimize your data storage system with efficiency.

The ICYCube MB561U3S-4S R1 supports both 2.5” and 3.5” SATA SSD/HDD with our new EZ-Tray design, allowing you to mix your 2.5” and 3.5” HDD within a single enclosure to save desktop space, power consumption and cost. The detachable 80mm cooling fan provides excellent cooling to the drives, and the 3 speed fan switch gives you full control over noise and temperature.

The ICYCube MB561U3S-4S R1 is a quad bay USB 3.0 & eSATA JBOD enclosure with removable tray design for hassle-free drive maintanence and swapping between different drives. It is perfect for media professionals, and people who need a high quality HDD enclosure for their storage needs.
Multiple Interfaces with Great Capacity

Having multiple drives conveniently placed into a single enclosure can provide many benefits such as the ability to transfer files between drives, backing up all your precious files or storing/organizing large archives. More importantly, doing this saves you big bucks from buying additional enclosures, gives you more desktop space and saves energy.

The ICYCube MB561U3S-4S R1 offers both USB 3.0 with UASP and eSATA interface. The UASP function on the ICYCube MB561U3S-4S R1 significantly increases the transfer speed of USB 3.0 interface. (UASP support at host end is required). Through the USB 3.0 interface, it allows you to access four drives individually and is backward compatible with USB 2.0, the most common interface for many things. This makes ICYCube the perfect HDD enclosure for various applications such as: media archives, data libraries, direct attached storage (DAS), network attached storage (NAS), external server storage, an IT data transfer tool and more. With USB 3.0 interface, you’ll have blazing fast data transfer speeds for any applications that require large data transfer on a daily basis.

The eSATA interface delivers fast SATA III speeds up to 6Gbps, and allows you to access four drives via a single eSATA connection (eSATA port multiplier required). It is compatible with most of RAID controller card that has eSATA port-multiplier interface, which gives you an option to setup a hardware RAID externally, perfect for system that has limited space. This tiny enclosure can take up to 40TB total capacity with largest capacity drives available on the market (10 TB), which is more than enough space for most of the applications.
The New EZ-Tray Takes It All
The new EZ-Trays provide the best compatibility for both 2.5” SATA HDD/SSD and 3.5” SATA HDD at all heights, ranging from lighting fast 2.5” SATA III SSD to 3.5” SATA 10TB HDD. The drive installation is simple: place the drive in the tray aligning the screw holes, screw in the provided screws, and you’re set! If you have more than four drives, additional trays can always be purchased. In addition to that, you can quickly swap out drive via hot swappable bays so you aren’t required to shut down your computer or the ICYCube, saving you valuable time. (Note: the USB host will refresh while swapping drive via USB. The remaining drive(s) will cycle during this process). The removable tray design is ideal for media professionals to easily swap out the 3.5” hard drives or 2.5” SSDs and then insert them into another EZ-Tray compatible HDD enclosure at different location for data transport. On the other hand, IT professionals can also take advantage of removable tray design since they are constantly swapping drives for OS drives backup or cloning multiple hard drives at once.
Better Cooling for Better Performance
Our ICYCube was designed from the ground up with intentions of fulfilling the demand of our customer base, so we packed it full of awesome features. It features an 80mm detachable fan for easy maintenance. Simply remove the fan unit, use a dust blower or a damp towel to wipe off the blades, and snap it back in; it can’t get any easier to clean. We’ve included a fan speed switch that allows you to select between a whisper-quiet low, a rapid cooling high, and an auto setting based on Smart Cooling Technology. The Smart Cooling Technology determines the temperature of your drives, and changes fan’s RPM accordingly to keep your drives nice and cool. Taking any heat source into consideration, the power supply is now built separately from the unit to prevent heat build-up inside the enclosure which in result reduced overall drive temperature. The ICYCube has maximized every cooling option to maintain the best performance and increase your drives' life span.
The Classic Remains a Classic
To define the ICYCube MB561U3S-4S R1 as “beautiful” would be an understatement. Crafted from Hi-Grade aluminum with two different available color schemes, the ICYCube sports a matte coat with a hint of glittery shine similar to that of Apple’s Macbook series. The front panel displays its fine glossy coat contrasting the outer housing in a unique blend. Our ICYDOCK logo is displayed on both sides so you can be assured that your product is an ICY DOCK –known for reliability and built tough. The low profile white LED indicator light indicates activity of each hard drive. This allows you to know which drives are currently being accessed or whether they’re sitting idle waiting for activity. We’ve used a moderately illuminating white LED for the indicator light so it shines just bright enough that you can be notified of activity, but not so bright where it’s distracting. Overall, the ICYCube MB561U3S-4S R1 is a fully featured quad bay USB 3.0 & eSATA external HDD enclosure that built for media professionals, IT professionals and computer-savvy users.
Lastly, ICY DOCK has a 3 year warranty which gives you the peace of mind to feel confident for years to come.

ICY DOCK ICYCube Quad Bay MB561U3S-4S R1 USB 3.0 External HDD Enclosure Review



ICY DOCK is well known for making high-quality products and the ICYCube Quad Drive enclosure does not leave you wanting in the quality department. The weight of the aluminum case is perfect, it provides a nice solid enclosure for housing your drives.

The performance of the ICYCube was also impressive. Of course, your choice of drives will affect your results, we were very pleased with our testing results and we suspect with higher end HDD’s or SSD’s you would see higher benchmark numbers. Having both USB 3.0 and eSATA interfaces on the ICYCube gives the unit flexibility for a variety of platforms uses. We do not see many platforms that use eSATA at this time but extra choices are always good

Up to 40TB External Storage - ICY DOCK ICYCube MB561U3S-4SB R1 Review



Up to 40TB of external storage is what this external HDD enclosure can take. But how does it work and what about performance?

ICY DOCK ICYCube Quad Bay 2.5" & 3.5" SATA External HDD Enclosure Review



We used the ICYCube MB561U3S-4S R1 for a total of 11 days and just by checking our charts you can see that it clearly managed to outperform most of its competition and even surpassed the very good Black Vortex quad bay enclosure again by ICY DOCK (although for the most part they traded blows). Sure it may not look as good as the Black Vortex (well at least we like it more) and the 80mm fan may not be nearly as effective or as quiet as the 120mm one featured in the Black Vortex (its perforated enclosure does play a large role in that as well so it's not just the 120mm fan) but thanks to its more "standard" design it can fit better on most desks (whereas the Black Vortex not so much). For good or bad the MB561U3S-4S R1 doesn’t offer RAID and large modes so It does fall short on that and we expect that some potential buyers will look elsewhere because of that. On the other hand however the easy removable 80mm fan with its 3-speed controller and the EZ-trays partially make up for that.
