Works very fast with my new Asus Laptop!5/11/2016 8:10:43 AM
SAVED at last !!!6/25/2017 7:43:36 AM
Pros: perfect.
Cons: none.
Overall Review: computer novices, don't think you can't do this.......there are two down load PDFs here, ( i would suggest RAID 1 ), and your looking then also for 2 identical SATA3 HDDs or SSDs.... after you get it together, in WIN 7 go Start > Control Panel > System & Security > Administrator Tools >Computer Management > Storage > Disk Management. anyway, i got two 1TB WD black drives, and opted to use the universal supply.....i like this unit because i think laptop drives are inherently tougher....if you think about the gyroscopic forces that must torture the bearings on a regular basis, with lap top physical movement while the drive is spinning...given a stationary RAID 1 application, i must say i feel quite data secure at this point....i think SSDs would have been great, but i have 2 SSDs in my Systems RAID zero array, and i paid almost twice what they are going for now 3 years later....so i am thinking SSDs for my StarTech, might be a distant future upgrade. really runs slick with the full version of Acronis True Image < i needed to get that anyway to shovel my system back into the RAID zero re-config.

Pros: Allows you to set four (4) different RAID Modes: RAID 0, RAID1, BIG, and JBOD. The user simply installs the drives, selects the mode, hold the green set button for ten (10) seconds when flipping the on switch, and allow the system to set the RAID of the drives. Simple to use without much effort. The system comes with enough screws to install your HDD/SSD as well as four screws to secure the case with the enclosure. It will take hyper drives as well.
Cons: If you don't understand the light system of StarTech items the. You may become frustrated with the device when trying to set the RAID. Understand that if you only get a red light when trying to set the RAID, one or more of your discs are damaged or failing soon. The system will only take good drives for the most part.
Overall Review: Overall it is a good product. If you absolutely don't know how to install it, type in the serial number on google and someone has a video of this product with a detailed installation guide.
Installation of hard drives4/18/2020 1:34:01 PM
Pros: Allen head screws
Cons: The Allen wrenches provided couldn’t un-seat the factory assembly
Overall Review: Had to use pliers to un-seat the screws required to be removed to install the hard drives. Manufacturer shouldn’t seat the Allen wrench screws so tight from the factory!
Manufacturer Response:
Hello Jason,
We pride ourselves on our high-quality standards and are sorry to hear about the issues you experienced while setting up our S252BU313R. The screws holding the front plate of this enclosure in place should not be so tight that you are unable to unscrew them and we'd like to speak with you about this. Please contact us at 1-800-265-1844 or www.startech.com/chat so that we can investigate this. Our Technical Advisors are available 24 hours a day, 5 days a week to provide support.

Disappointed6/3/2014 12:57:32 PM
Pros: Works. Easy to install.
Cons: I just purchased this enclosure and connected it to a late 2013 MacPro. Mounted two SSDs in it and tested with BlackMagic. Kingston SV300S37A/120g (141.3.4 MB/s write) and an OWC EX6G120 (132.4 MB/s write). Read times (329.5/246.0) beat the pants off an external HDD (USB3), but write times weren't a whole lot faster. No comparison to internal PCIe SSD which pinned both gauges at 797.8 write and 931.9 read. I hooked the OWC drive up with a USB 3 connector and the test results were 124.0 write and 218.2 read. Slower than the 132.4/248.0 using the StarTech Thunderbolt enclosure, but the difference seems hardly worth the price. I'm really kicking myself for not spending the extra $300 for the 512GB PCIE drive.
Overall Review: Internal fan seems like overkill as unit and most SSDs generate very little heat. The noise isn't bad, but sitting next to a silent MacPro you can hear it.
Not ready for use1/31/2018 4:45:22 AM
Pros: I like the case and is very easy to setup.
Cons: Disconnects then reconnects when other USB devices are plugged in and does the same when another USB device is removed. This happened on Windows 10 fully patched.
Close but not quite.5/2/2016 9:08:03 AM
Pros: I like the concept of this device. It was able to accommodate 15mm thick drives. How raids are selected was pretty straight forward. The universal outlet with all of it's attachments for many countries gave me a laugh.
Cons: I'm not sure what went wrong with my set up. I was trying to use some old SATA I Western Digital Raptor 10,000 rpm drives. They were 2.5 form factor (>15mm thick). I attached them directly to my computer to test them and did a full reformat of the hard drives. But they would not work inside this enclosure on any raid setting. I went on the manufacture's website before purchasing this and I couldn't find a compatibility list. So, I assumed it would work with all SATA I devices. Not sure if it wasn't functioning or compatibility issue.
Overall Review: Thanks Newegg for making the exchange process painless.
Nice Piece12/3/2015 10:03:08 AM
Pros: Arrived an hour ago - well packaged - all things needed included - easy set up instructions - all good Ran ATTO and AS SSD benchmarks - read/write speeds with both were right on.
Cons: For the 1st time in any review, I was tempted to use the phrase "This unit looks "cute" on my desktop" - glad I didn't ;-)

Pros: Using with my new Asus Laptop for video editing. The 3.1/Thunderbolt 3 connection is very fast. Box runs cool and is very quite . I'm running 2 2.5" drives in it, but will eventually get some SSD drives for it. I would recommend this to anyone who is using the new 3.1/Thunderbolt 3 connection.
Cons: none
