Good value for the price.

I bought this as I had 4-2TB drives collecting dust and thought it would make a nice simple backup drive for my home lab using VEEAM. The device itself is okay, for the price it's a great value, though the workmanship isn't great. The drives don't align very well with the connectors and the bottom drive is very difficult as there isn't any clearance to 'work it' into the slot (maybe it was my gorilla hands, but it was difficult). It took me longer to manipulate the drives to seat properly than it did to get everything else on it running. Over all I am happy with it. Simple to setup, pretty intuitive.

No so much...

Usually a fan of Startech products but not so much for this one. Arrived with a defective power supply.. which i can overlook.. it happens. But overall quality of device is poor. Flip-down cover falls off continually when opening, drives do not fit into may with ease... requires repeat attempts, wiggles to get it in. Generally a poor (built) quality device. Does not inspire confidence which it should considering it is a semi-professional type of device.

Hello, we're sorry to hear that your experience has not been ideal with that enclosure. Generally we receive great feedback from our customers using it. Have you had the adapter replaced yet? If not, we would like to assist with that as well as hear more on the rest of the points you've made. Please call use at 1-800-265-1844 or support@startech.com.

Great product! I own 2!

Excellent versatile product with the right price. I used to own an older version of this and was having all sorts of issues which at one point made me give up... But I risked to buy this product and it was a total satisfaction with no problem. So I decided to buy a second one with the same degree of satisfaction. I would recommend this specific product to any friend

Sorry to hear the older version didn't do so well for you, but it's great that your recent experiences with the SAT3540U3ER have been so positive. Thanks for letting us know.

Small Business Workhorse

I don't know what the actual rating on this is for run time or MTBF, however I've had it on for about six months non stop being accessed constantly by about five users during day and running bulk backups over night. This thing is a solid workhorse for my small business running quad 4TB in RAID 5 over eSATA. USB3.0 is okay at burst transfers however this is not the fault of the enclosure, but rather the real world shortcomings of USB in general. I'm guessing a UASP and/or Thunderbolt version will be in the works? Maybe a Six bay unit? I really don't want to have to buy something a pre loaded unit from someone else when I out grow this.
