Pros: Has a small footprint, solid construction and, when loaded with drives, has some wight to it.

Cons: Operation selection of the unit can be cumbersome.

Overall Review: I really have nothing bad to say...StarTech has been and will always be my "go to" company for oddball accessories. I had to knock one egg off because of the setup procedure. It should be noted that this is no fault of the product, but of the user manual; or rather lack of. It took some messing around with to get the operation selection I wanted. In short, I discovered that you need it connected to something upon power-on in order for the change to commit. Otherwise it will simply spin down the drives. I was going for a RAID-1 setup and I kept seeing only one drive (as in the actual drive model number) versus seeing it as a RAID device (using eSATA and my controller does not support port multiplication). The best way I found out (if you don't have hot swap support) is to turn on your computer, halt it at the BIOS screen to suspend boot-up. At this point, change the selection switch to the mode you want, hold the "set" button, power-on the unit and release the "set" button. After about five seconds or so, just Ctrl-Alt-Del you computer to restart it and your BIOS should detect it as the new setup. In my case, it changed from the actual hard drive model number (JBOD) to "ATA SSI H/W RAID1 Device". Port multiplier support is only required for JBOD as all other methods are transparent to the BIOS and they never need to see the actual hard drives behind the unit. All other things considered, this is by far a great product. I own two of the black units and one of the white ones. StarTech also makes the black one in a NAS version that swaps the eSATA port for a NIC. They recently released a 4-bay model of the black unit (it only supports JBOD though). I'll probably be in the market for a couple of the 4-bay units for adding attentional drives to my NAS4Free box since hardware RAID is not required. In summation, I would highly recommend this product for the price point it is at.

Pros: Has a very basic exterior design. Nice small footprint. Easy to put together.

Cons: Very very very poor internal layout! Has basically no air flow even if you install the "optional" fan. Which the position to install the fan has to be modified in order for and common fans to be installed. That being said, the case generates standing heat pockets even with the fan. Not to mention the HDD sits right on top of the CPU heat sink! Had this for about 3 months. If not keep in an environment less than about 70 degress F, it shuts down from heat. Sad to report that the PSU board inside burnt up and died. I opended the case to see what happened and all the connectors were yellowed from excessive heat. The hard drive's label was chared and when I plugged it to to see what the cause was, a flame burst out on an inductor on the PSU board!

Overall Review: Nothing but a fire hazzard! Not to mention, who designs a case with an "optional" fan? First and last time I will every buy from this company! Just glad I was home when the PSU board caught on fire...

Pros: It fits.

Cons: Died in less than 24 hours!

Overall Review: Purchased this to replace an already dead PSU in my step-daughter's desktop. What a disappointment to fix her computer only to have it die in less than 24 hours...LESS THAN 24 HOURS!!! Before anyone jumps to the obvious and say it was probably some other hardware that was bad since it was the second PSU...I ran this setup with a reputable ATX PSU externally for days without any problems. Sick and tired of these garbage FLEX PSU's. I decided to replace the case so that I can fit a standard ATX PSU inside.

Pros: Has a small footprint, solid construction and, when loaded with drives, has some wight to it.

Cons: Operation selection of the unit can be cumbersome.

Pros: All four ports have header connections. Includes low profile brackets. Kernel module source code available on StarTech's website.

Cons: None.

Overall Review: What can I say, StarTech never dissapoints. I always look to them for odd hardware like this that works in Linux. Had trouble locating the source code for the MosChip on this card to compile the kernel module. Decided just to look on StarTech's website vs. MosChip's website and there it was waiting for download! Compiled fine and a reboot later I had a working card. Also, all four ports have header/ribbon cable connections to the card which makes this perfect for people like me who like to add hombrew controllers internally in the case and need to "hi-jack" the connection to the port to do so; leaving the only external item as the remote device connected to the port. I loved this card so much I just purchased my 4th one. I do hope StarTech keeps this card in production for a long time as it is the only one I can find like it and I plan on purchasing more down the road.

Pros: Has you basic I/O interfaces with some extras. Supports DDR2 or DDR3 RAM. Stable at default clocking (I purchased this with the intention NOT to overclock). Low power consumption means low heat output. Fits the void for a shrinking market.

Cons: None.

Overall Review: I purchased this to setup a local environmental monitor running Linux (CLI only), and some extras, to process some input/output for some homebrew sensors I have made. Added a four port serial PCIe card and a two port serial PCI card for a total of seven serial interfaces for my sensors. Combined with the onboard parallel interface I have all the ports I need in a small form factor, low power monitor. Sometimes you just need a small simple system like this and, in the world of gaming, this fits a shirking market. I liked it so much I just ordered another for my next homebrew project.
