In preparation for the HomeServerShow Meetup 2015 I was asked to review the Icy Dock ExpressCage MB324SP-B – 4 Bay 2.5” SAS/SATA HDD Hot Swap Cage for 5.25” Bay (“ExpressCage”).


Specifications of the ExpressCage

Icy Dock provided a list of specifications and product detail that I found very intriguing including support for four 2.5” HDDs/SSDs up to 12.5mm thick, hot-swap support, and SAS/SATA – 6GB/s support. All in a 5.25” half-height form factor needing only one SATA power port. One of the things I wanted to display at the meetup was how to use the HP ProLiant N40L MicroServer as an external 4 drive bay for an HP ProLiant Gen8 MicroServer AND have Microsoft Server 2016 Technical Preview 3 running on the N40L, using an SSD for the OS drive, and with four 2.5’ HDDs available to experiment with Storage Spaces – all of this in a single N40L MicroServer would be possible because of the ExpressCage MB324SP-B.

Later, after the meetup, I wanted to test the ExpressCage in my desktop computer which will be a separate review. The ability to mount 4 SSDs in the ExpressCage powered by only one 15-pin SATA Power connector would help immensely in cable management and the looks. I would use the 4 SSDs in the ExpressCage in a RAID0 configuration to use as my work drive for video editing.

Figure 3 – The single 15 Pin SATA Power connector would be a great plus in my mind for cable management – this would be a big help in the N40L as well as my Z77 Desktop


Fig 04

Figure 4 – The ability to control the fan speed settings is a great feature – since I would be using low powered WD 2.5” drives in the N40L and low powered Samsung SSDs in the Z77 desktop I used the low fan speed setting

Figure 5 – The extra thought in the design to allow me to switch out the 40mm cooling fan in the future is a great indicator of good design practice, in my opinion

Figure 6 – I like to use locking clips and appreciate the physical and audio feedback they provide during installation. The Blue LED’s provide me feedback that the drives are powered

Figure 7 – The built-in screws secure the drives well that I was using

Figure 8 – Icy Dock provides screws that could be used to further secure the drives to the caddy but I found no need for them – it is nice that they are available though


When the ExpressCage arrived, I wanted to unbox it as soon as I could and get to work preparing for the Meetup.
