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.

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

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.

Hard to Beat for the Price

Though not "enterprise grade" compared to, say, big rack-mount disk enclosures, these are very spiffy units. Set us as RAID5 with four 1 Tb drives, these make very nice virtual-machine storage units. We've used them in our corporate environment for years, and none have failed yet. Does well with RedHat/Centos Linux, Windows servers. Keep the packing box - - it's nice if you want to travel with the unit.

Hello, Thank you for taking the time to review our SAT3540U3ER. We are sorry to hear that the RAID has failed and we would like to offer some help. With the power LED being orange with no other LED’s lit up it sounds like the enclosure is currently in sleep mode. For the data that was on the RAID originally, do you have any back-ups available? After changing the RAID mode away from the original setting you had used the data will unfortunately wiped from the RAID enclosure. We recommend following the steps in our product manual on Page 5 to set up the enclosure again. Here is an article which can be found on the support page for this product which covers the process of setting the RAID mode: http://www.startech.com/faq/hard_drive_enclosures_sat3540u3er_raid_setup_change#SAT3540U3ER We are always here to help with our free lifetime technical support. If this did not resolve your issue, please get in touch with us and reference case #332-285886 so we can further assist you. You can also reply here and we will be sure to follow up.
