ICY Dock Blizzard MB080U3S-1SB 3.5” USB 3.0/eSATA External Enclosure Review

Rating: 7.5.

Today we are looking at an enclosure by ICY Dock, the Blizzard (MB080U3S-1SB), a creatively designed single 3.5″ bay featuring both USB 3.0 and eSATA connectivity.

ICY Dock have built this new enclosure from the ground-up to have an elegant appearance but yet incorporate a large 80mm cooling fan. The advantages of this design? With the fan positioned at the front and the vents at the rear it can create a tunnel of fast moving air … much like a turbine engine, allowing all sides of the hard drive to be cooled very efficiently.

ICY Dock have also managed to create an enclosure which can house a 3.5″ drive securely without the use of any tools – great if you want to switch drives at any point.

    Interesting product but I wonder where the market is. The only market I see for 3.5″ enclosures is for reusing old drives you’ve replaced with bigger ones, and I’m not going to spend a lot of money on that.

    Simply put this review is a complete waste of time, and reads like a brochure.
    You reviewed a Hard Drive enclosure purposely designed for cooling, and didn’t even put a Hard Drive inside it!
    You put in an SSD (which as everyone knows generate allot less heat in use).

    So your whole review tests the speed capabilities of this units I/O board.
    Simply put who cares about the throughput on an enclosure such as this, it’s whole purpose is to cool large capacity Hard Drives, and with the current generation of HDD’s experiencing overheat problems in standard enclosures, it might be nice to see a thermal graph / diagram of this units performance over time.
    This review is a perfect example of a lazy and stupid product testing, that anyone on any computer could do in there sleep.
