5 out of 5 eggs6 years later and still going.

Pros: Got This unit a while back, half expected it to fail as I had never heard of startech. 6 years later, still using the unit with my HTPC, had ZERO issues. Fan still spinning, drives still reporting. Not the fastest (using it USB only) Maxed it out to just under 4T. Every time I go in to manage the files I am still expecting a fail.

Cons: Only a few minor cons. The placement of the power cord is... no smart. Uses this wonky 90 degree connecter to the side, meaning you can set that side flush against anything. I also question the durability of the plug its self. As it is not protected in any way, it feels like if its bumped at all it might just snap right off. The power plug uses a strange 4 pin connecter, so if you loose it your never going to be able to replace it. Not sure why they didn't use a more normal connecter type.
When turning off the computer connected to the enclosure the enclosure turns off (which is fine) but it will not come back on with the computer. you have to turn the enclosure back on separately (not a big deal but a annoying, and if you set up your HTPC to be turned on remotely via IR or other means its kinda mote if you still have to walk over to the enclosure and hit a button)

Other Thoughts: I have had 4 of these 4 bay enclosures hooked up to a HTPC. the other 3 are from different manufactures. This one has been the best in terms or reliability. Its not fancy, has few features (and is now out of date) but it just plain works. I have thought about getting the newer one with usb3.0 but it seems to be having all kinds of issues...

4 out of 5 eggsExcellent product

Pros: Pros: I'd say it works everything on it works completely as it says. Tested both esata and usb with 4 drives in it an actually different kinds of sata drives as well to see how it dealt with dif sata hd build technologies. Works well... For the price you can't beat it I got it cheaper than what its adv at right now but still a good product.

Cons: Front door is kind of tricky when you first get it seems flimsy but really isnt just has to be setup properly. NO USB 3.0 which isn't cool! I would have gotten the 3.0 if i could have found it anywhere. No other cons besides that.

Other Thoughts: Like I said wish there was a usb 3.0 that was cheaper I bought two of them Im gonna run them esata with an esata card... Worth it for now I will get the 3.0 when made and or price drops on other models of usb 3.0 arrays.

1 out of 5 eggsNot working out of the box.

Pros: NONE. I needed this to replace a failed enclosure that got hit by a power outage. Paid for next day delivery and it wasn't even shipped until Noon the next day.

Cons: Only USB connection works. The esata connection did not work at all and when I tried the connection the unit would stay on for about 10 seconds and shutdown.

5 out of 5 eggsCheaper @ NewEgg and holds 16TB

Pros: According to StarTech's website, these will hold up to 4TBx4 for 16TB total. Also, these are $214.99 on their site so get one here as we all know NewEgg has fast shipping and great service.

Cons: None so far

5 out of 5 eggsrecommended

Pros: nice unit, 3 modes on fan speed, very quiet running on lowest speed, not that loud on highest speed too. blue led make the unit looks even cooler.

Cons: hope starttech will make a usb3.0 interface in the future. when installing the hdd, make sure it plug it to sata port 100%.

5 out of 5 eggsAmazing

Pros: Plug-n-Play. Automatic access. Fast disk speed. It's the best thing I've added to my system since my 1tb. All my drives are filled with video footage, no lag time so far and editing is still a snap. Plus, doesn't get over heated and my computer stays safely cool.

Cons: Front face plate refuses to stay on. Four slots are not enough for me, but that's just me.

Other Thoughts: I need another one.
