ICY DOCK MB561US-4S-1 Quad Bay External Enclosure Review

Large volume external storage has also been and will remain to be popular just for the fact that many people do not have room inside their cases for extra hard drives.  Also external storage allows you to easily use that storage on multiple systems with minimal effort.  With the introduction of eSATA external drives can now be just as fast as internal drives so we have seen quite a few eSATA external enclosures released lately.  Today we will be taking a look at the MB561US-4S-1 Quad Bay External Enclosure from ICY DOCK that features an internal port multiplier and both eSATA and USB 2.0 connections.  Let’s take a look…
