The rear of the IcyDock MB453SPF-B unit has three SATA data connections, and either SATA I or SATA II hard drives can be used with the product. There is a SATA style power connector for the first hard drive, and 4-pin molex type power connectors for HDD2 and HDD3.

All three hard drives power up when any one of the three power plugs is populated. There is no indication as to whether just one power connection is insufficient, or if all three are required. It seems to be that just one will do though. Naturally, each of the three SATA data connections must be connected with your own SATA cables to corresponding SATA headers on the motherboard. No SATA data cables are included with this product.

A small forest of jumper pin headers can be used for monitoring hard drive failure and access status with certain motherboards, but the majority of consumer systems will have absolutely no need for any of this. Three 60cm long 2-wire green and black cables are included in the package specifically for this feature.

The only other control you really may be interested in on the IcyDock MB453SPF-B is its temperature alarm which can be set to buzz off at 45°C, 55°C, or 65°C. The 80mm fan clips into place with a special set of power jacks, and is hot swappable too. If the host drive can provide a hard drive failure signal, of if temperatures reach the threshold, a nice loud alarm will sound alerting you to the problem. Furthermore, a pair of red LEDs will glow brightly on the front of the unit if either situation occurs. A small reset button on the front will silence the siren.

(Note: SATA hard drives are not included with the product, you will need to supply your own.)

In the likely situation that the single sheet of "instructions" is misplaced, a sticker with the pin-outs is affixed to the bottom of the three-bay SATA hard drive module. Nice. Now let's wrap up this review and highlight some of the aspects of IcyDock's product that are likely to be of most interest to you next.....
