A great case for extending via SFF-8088 to Adaptec card; effective fan and nice design. Note that this case does not have the same drive mounting than the 8 drive version of the same case - a little annoyance...

Good unit 23 Aug 2013
By M. Burke - Published on Amazon.com
Verified Purchase

* Great value, supports 6G
* Doesn't look bad
* Reasonable cooling/airflow
* Comes with 8088 SAS cable
* With a bit of care, you can hot swap the drives


* Changing drives is a little work, but totally doable. The inconvenience of the low-tech "tray" approach is overblown.
* A slightly longer cable woulda been nice

Other thoughts:

The cons are very minor. This is a budget box, and the bang for buck is very high; it does all the basic functions well.

UPDATE: The fan in there is adequate, but not fantastic. My consumer drives are running around 50C while the enterprise drives around 44C doing heavy activity with about 30C ambient temps. It feels they made the fan quiet instead of super high flow. I feel this was the right choice.

Definitely consider enterprise quality drives, even when stacked right next to the much warmer consumer drives they run a lot cooler.

Good for the money 7 Jan 2014
By Thomas Swafford - Published on Amazon.com
I researched external SAS chassis for some time before deciding on this one. Since this is being installed in a residence, size and acoustics were my primary concerns and in those areas the system doesn't disappoint.

This is for the TR4X+B (note there is a difference between the plus and the non-plus units)

Mine is plugging into HP Smart Array controllers (P410 and P411) and it works perfectly so that can be added to the listed of working RAID controllers. It fully supports my 3TB drives as well and at the rated 6Gbp/s speed.

The unit is very quiet with 4 drives installed and as the previous reviewer noted, my enterprise SAS drives (7200 rpm) are running between 40-42 degrees Celsius. While far from optimal that is still adequate given the noise trade-off. Data center chassis would typically keep these drives cool at around 35-C but with acoustics of about 63bd at 4 feet.

The trayless design is nice BUT that comes at the price of difficulty removing to top drive without pulling the top cover of the unit off. It's a little difficult to get a grip on any of the drives without shifting the others - while they don't disconnect from the backplane, it is a concern for hot swap operations. I may fashion some sort of pull tab that sticks to the bottom of the drive to make removal easier if it becomes an issue.

If I had to make a gripe it would be that the manufacturer chose to put an LED fan in the unit which makes the rear of the unit light up 'blue'... not bad mind you, just a mention if that might bug you.
Perhaps the best solution for such a price. 18 Jan 2014

I'm using it with my HP Microserver Gen8 & SmartArray P222. No problems detected :)
Little uncomfortable installing drives, but if they do not need to shoot often, this does not prevent.
