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.
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.
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.

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, ex-FAT, NTFS, and so on).
Note: You typically only need to initialize a drive if the drive is new. If you cannot find an uninitialized drive in Disk Management, skip the following steps and try to partition your device.
Press the Windows key + R, type compmgmt.msc, and click Run to open Computer Management.
Navigate to Disk Management.
When prompted to, initialize your disk(s). If you are running Windows® 7 or later and are using a drive larger than 2TB, initialize the disk(s) with GPT. If you are running an earlier version of Windows, initialize the disk(s) with MBR. For more information, visit the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=hard-drives#mbr-vs-gpt.
Note: The following steps create an NTFS partition that uses the entire drive space. To use a different file system, select a different option in step 6.
Right-click Unallocated or RAW volume, and select New Simple Volume.
In the New Partition Wizard, click Next.
Select Primary partition.
Leave the partition size set to default, and click Next.
Assign a drive letter or leave it set to the default, and click Next.

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, HFS+, ex-FAT, NTFS, and so on).
Mac OSX detects a drive that needs to be initialized and automatically prompts you to initialize the drive. If you are prompted to initialize the drive, click Initialize. If you are not prompted to initialize the drive and you cannot find the drive in Finder, you will need to create a partition on the drive.
Note: The following steps create an HFS+ (Mac OS Extended (Journaled)) partition that uses the entire drive space.
To create a partition on a new drive, complete the following:
Navigate to Applications and click Utilities.
Open Disk Utility.
Select the new drive and click the Partition tab.
Click Options and verify that it is set to GUID Partition Table.
