This USB 3.1 Gen 2 single-drive enclosure gives you an ultra-fast, portable external storage solution for 2.5” hard drives or solid-state drives up to 15 mm in height. The enclosure provides quick access to your data wherever you go and it lets you retain your data after an upgrade to a new SSD or HDD in your computer.

Ultra-fast performance

The drive enclosure lets you leverage the high performance of the latest SSDs and HDDs. USB 3.1 Gen 2 also gives you greater bandwidth and speeds up to 10Gbps for ultra-fast access to your data. IT professionals, medical personnel, researchers, creative professionals and anyone else who needs easy access to their data on the go will benefit from this portable drive enclosure. The enclosure lets you quickly access your data, to browse your files and edit your documents.

The enclosure also provides you with easy drive access for data migration, drive cloning, and data backups so that you can safeguard your data at all times.

Versatile and compatible

Unlike most drive enclosures, which only support SATA SSDs and HDDs up to 9.5 mm in height, this enclosure is compatible with virtually all 2.5" SATA drives up to 15 mm in height. Plus, it comes with a USB Type-C to Micro-B cable, for connecting to newer USB-C enabled laptops, tablets, and phones. A USB Type-A to Micro-B cable is also included to ensure backward compatibility with your existing USB 3.0 and 2.0 devices.

The enclosure is powered directly from the USB port on your device, which means no external power is required. For portable storage, you can tuck it away inside your laptop bag or carrying case and take it anywhere -- from your home to the office, the hospital, the lab, or out in the field, so that you can access your data wherever you go.

Protection for your data

The enclosure is engineered with a sleek and durable aluminum housing to help keep your data safe and secure wherever you go. Its aluminum housing and venting help to dissipate heat and passively cool the drive in order to help prevent drive failure and data loss.

The S251BU31315 is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Frequently Asked Questions

Troubleshooting

You should not upgrade your device's firmware if you do not have any issues with the functionality of your device. The only time you should consider an upgrade is if you are experiencing a problem with the device, and you have confirmed that the firmware addresses this problem.  You can confirm this is the case by reviewing the documentation included with the firmware or by consulting with our Technical Support team. Incorrectly upgrading firmware can result in diminished performance so it is best to contact StarTech.com if you would like to perform this operation.

When you troubleshoot issues with a hard drive enclosure, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Cables
  • Hard drives
  • Hard drive enclosure

To test your setup components, try the following:

  • Use the cables, hard drives, and hard drive enclosure in another setup to see if the problem is with the components or the setup.
  • Use a different cable, hard drive, and hard drive enclosure in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test the hard drive and hard drive enclosure, it is recommended that you do the following:

  • To check Disk Management, press the Windows key + R, type diskmgmt.msc, and press Enter. Check to see if your hard drive is listed.
  • If the hard drive is listed with unallocated space, the hard drive needs to be reformatted. Right-click unallocated and click New Simple Volume. Follow the on-screen instructions to complete the reformatting.​

Note: Formatting a hard drive erases all of the data on it. Make sure that you back up all of your data before you reformat the hard drive.​

  • If the hard drive is listed as healthy but does not have a drive letter, for example, C:, right-click healthy and click Change Drive Letter and Paths. Click Add, assign a drive letter, and click OK.

Note: A formatted hard drive will not show up in Computer or My Computer until it has a drive letter assigned to it.

Before You Buy

Yes, this device supports the TRIM command. If the OS issues a TRIM command, the command will be passed to the connected device.

To determine if your hard drive will work in this enclosure, on the product page, click the Technical Specifications tab, and do the following:

  • Make sure that the enclosure supports the storage size of your hard drive. If the storage size of your hard drive is larger than what the enclosure was tested with, the hard drive will likely still work with the enclosure.
  • Confirm that your hard drive uses the same interface type as the enclosure. For example, IDE, SATA, or M.2.
  • Make sure that the enclosure supports the physical size of your hard drive, such as 2.5 inches or 3.5 inches.
  • Make sure that the enclosure supports the height of your hard drive. For example, 9 mm or 15 mm.
  • Verify that the power consumption of your hard drive doesn’t exceed the power output of the enclosure. If you’re using multiple hard drives, make sure that the combined power consumption of all of the hard drives doesn’t exceed the power output of the enclosure.

Great enclosure

By: Jesse K - 03-17-2017
I bought this last week from Amazon, for a 15mm drive where the enclosure failed. I've purchased StarTech cables & adapters before, but this is the first one that motivated me to leave a review. It's solidly-built and lightning-fast on USB 3.1, I'm getting ~500MBp/s on a Seagate Freeplay. Decent enclosures of this size are tough to find, so just get this one :)

Supports 5tb 2.5" hdd (the largest 2.5" hdd on the market) 2 partitions in MBR (due to mbr restrictions mbr doesn't support one single 5tb partition it will always force 2 patitions in large drives) or one single partition in GPT
