The UGREEN US221 30847 2.5-Inch SATA HDD/SSD Enclosure is a practical and high-speed storage solution that lets you convert an internal 2.5-inch SATA HDD or SSD into a portable external USB drive. Featuring a USB 3.0 interface with transfer speeds of up to 5Gbps, SATA III compatibility and UASP support, it is an excellent choice for upgrading storage, accessing an old laptop drive, transferring large files, creating backups or turning a spare SATA SSD into portable storage.

The enclosure supports 2.5-inch SATA I, SATA II and SATA III HDDs and SSDs, including common 7mm and 9.5mm drive thicknesses. It connects to your computer through USB-A and is designed for straightforward plug-and-play operation without requiring a separate power adapter for standard 2.5-inch drives.

With its compact construction, internal protective padding and activity LED, the UGREEN 30847 is suitable for everyday storage, professional data transfer, backup applications and portable computing.

Importantly, this is an enclosure only. An SSD or HDD is not included.

Turn Your Internal Drive into Portable Storage

Have an unused 2.5-inch SATA SSD or HDD from an old laptop?

Instead of leaving it unused, install it inside the UGREEN US221 30847 enclosure and use it as an external storage drive.

This can be particularly useful when:

• Upgrading an old laptop
• Reusing an older SATA SSD
• Accessing files from an old laptop HDD
• Creating a portable backup drive
• Transferring files between computers
• Expanding laptop storage
• Creating an external media library
• Keeping a secondary copy of important files

The enclosure essentially provides a bridge between your internal SATA storage drive and a computer's USB port.

USB 3.0 SuperSpeed – Up to 5Gbps

The UGREEN 30847 uses USB 3.0, providing a theoretical interface speed of up to 5Gbps.

This is significantly faster than USB 2.0 and makes the enclosure suitable for transferring large files such as:

• Videos
• Photos
• Documents
• Software
• Game files
• Project files
• Backups
• System images

Actual transfer speeds depend on the installed SSD/HDD, USB port, computer, file type, operating system and other hardware limitations. The 5Gbps figure represents the maximum USB interface link speed rather than guaranteed sustained file-transfer performance.

UASP Support for Improved Storage Performance

The UGREEN US221 30847 supports UASP (USB Attached SCSI Protocol).

UASP is designed to reduce USB storage protocol overhead and improve command handling compared with traditional USB mass-storage operation when both the enclosure and host system support UASP.

This can be especially beneficial when using the enclosure with an SSD.

The UASP feature requires a compatible computer, operating system and USB controller. It does not mean every drive will achieve a fixed percentage performance increase.

SATA III Compatibility

Internally, the UGREEN 30847 uses a SATA connection and supports SATA I, SATA II and SATA III drives.

SATA III supports a theoretical interface speed of up to 6Gbps, while the enclosure's USB 3.0 connection provides the external host interface at up to 5Gbps.

This makes the enclosure suitable for both SATA HDDs and SATA SSDs.

It is important to note that this model is not an M.2 enclosure and does not support M.2 SATA or NVMe SSDs.

Compatible with 2.5-Inch SATA HDDs and SSDs

The UGREEN US221 30847 is designed specifically for 2.5-inch SATA storage drives.

Supported drive types include:

• 2.5-inch SATA I HDD/SSD
• 2.5-inch SATA II HDD/SSD
• 2.5-inch SATA III HDD/SSD
• 7mm SATA drives
• 9.5mm SATA drives

The exact model documentation identifies the enclosure for 2.5-inch SATA drives and lists compatibility with common brands including WD, Seagate, Samsung, Crucial, Kingston, Toshiba and others.

Tool-Free Installation

Installing your drive inside the UGREEN 30847 is designed to be simple.

There is no complicated assembly process or separate mounting bracket required.

Simply open the enclosure, connect your compatible 2.5-inch SATA drive to the internal SATA connector and close the housing.

This makes the enclosure especially convenient when you frequently move or replace SATA drives.

No Separate Power Adapter Required

The UGREEN 30847 is designed to obtain power through its USB connection.

For normal compatible 2.5-inch SATA HDDs and SSDs, there is no separate AC power adapter required.

This makes the enclosure much easier to carry than larger external-drive solutions.

Simply connect the enclosure to a compatible USB port and the installed drive can be powered through the USB connection, subject to the host's available power.

Protective Internal Padding

The enclosure includes internal protective material designed to help keep the installed drive securely positioned.

The internal padding helps reduce movement and protects the drive from contact with the enclosure during normal handling.

This is particularly useful when carrying a mechanical HDD.

However, the enclosure should still be handled carefully because an HDD contains moving mechanical components.

LED Activity Indicator

An integrated LED indicator provides a visual indication of the enclosure's operating/activity status.

This makes it easier to determine whether the drive is powered and communicating with the connected computer.

Always safely eject the drive through your operating system before disconnecting it to minimize the risk of data corruption.

Portable and Compact Design

The UGREEN 30847 is designed to be carried easily with a laptop or stored in a computer bag.

Its compact 2.5-inch form factor makes it suitable for:

• Office use
• Home use
• Travel
• IT support
• Data migration
• Backup
• Laptop upgrades
• Temporary storage

It is significantly more convenient than carrying an internal drive without any protective enclosure.

Wide Operating System Compatibility

The UGREEN US221 30847 is designed to work with major computer operating systems.

Compatibility includes:

• Windows
• Linux
• macOS

The model documentation lists support for Windows versions including Windows 2000, XP, Vista, 7, 8, 8.1 and 10, along with Linux and Mac OS 8.0 or later.

Modern operating systems generally recognize USB storage devices automatically, although file-system compatibility and host-specific requirements can affect whether a drive is immediately accessible.

Useful for Laptop Drive Upgrades

One of the most useful applications of the UGREEN 30847 is laptop storage replacement.

When upgrading an old laptop from a hard drive to an SSD, you can place the old SATA drive inside the enclosure.

This allows you to:

1. Install a new SSD in the laptop.
2. Put the old 2.5-inch SATA drive inside the UGREEN enclosure.
3. Connect it through USB.
4. Access your previous files externally.

It can therefore be a convenient accessory during storage upgrades and data migration.

Useful for Data Recovery and File Access

If a laptop stops working but its internal 2.5-inch SATA drive is still functional, the UGREEN 30847 can provide a convenient way to connect that drive to another compatible computer.

You can potentially access files stored on the drive if the drive itself is healthy and its encryption, permissions and file system allow access.

The enclosure itself does not repair damaged drives or bypass encryption/password protection.

Ideal for SSDs

Using a SATA SSD with the UGREEN 30847 can create a compact external storage solution.

Compared with a mechanical HDD, an SSD generally provides:

• Faster access times
• No moving mechanical parts
• Better resistance to movement
• Quiet operation
• Lower mechanical noise

Actual external performance will depend on the SSD and USB connection.

Ideal for 2.5-Inch HDDs

The enclosure can also be used with traditional 2.5-inch SATA HDDs.

This makes it useful for turning an old laptop hard drive into:

• Backup storage
• Archive storage
• Media storage
• Document storage
• Secondary storage

For mechanical HDDs, handle the enclosure carefully and avoid shocks while the drive is operating.
