UGREEN 30848 2.5-Inch SATA Enclosure, 5Gbps USB-A

Overview

UGREEN 30848 houses one 7mm or 9.5mm 2.5-inch SATA HDD or SSD and connects it to a USB-A host through a detachable cable. The guide below separates drive protocol, physical size, host link and real-world limits so buyers can choose safely without confusing SATA, M.2 and NVMe.

Key features

Exact storage role

houses one 7mm or 9.5mm 2.5-inch SATA HDD or SSD and connects it to a USB-A host through a detachable cable.

Supported drive

2.5-inch SATA I/II/III HDD or SSD, 7mm or 9.5mm high.

Connection path

Detachable 30cm USB 3.0 Micro-B to USB-A cable; internal SATA III, 7+15-pin.

Thermal and controller design

Black plastic enclosure with internal EVA pads; ASM1153E on current official UGREEN product material.

Understand the complete storage path

1. The drive

2.5-inch SATA I/II/III HDD or SSD, 7mm or 9.5mm high.

2. Internal bus

SATA III, 7+15-pin. This is the protocol used between the installed drive and bridge.

3. Enclosure bridge

ASM1153E on current official UGREEN product material. The bridge translates the drive protocol to USB mass storage.

4. Host connection

Detachable 30cm USB 3.0 Micro-B to USB-A cable. The host port, cable and any hub must support the required data mode.

Do not shop by shape alone: not for 3.5-inch, M.2 SATA, M.2 NVMe, mSATA or IDE/PATA drives. An M.2 notch does not by itself identify SATA versus NVMe, and a USB-C connector does not guarantee USB4 or 10Gbps.

Drive compatibility: form factor, key and capacity

Compatible: 2.5-inch SATA I/II/III HDD or SSD, 7mm or 9.5mm high.

Not compatible: not for 3.5-inch, M.2 SATA, M.2 NVMe, mSATA or IDE/PATA drives.

Capacity guidance: Up to 6TB on the exact India handle and live gallery; some newer regional tables conflict, so 6TB is the conservative model-specific limit used here.

Brand examples are not enough: the same SSD brand can sell SATA and NVMe products under similar names. Check the exact model’s protocol, dimensions, key and any pre-installed heatsink before purchase.

The exact India gallery supports 7mm or 9.5mm 2.5-inch SATA HDD/SSD and states up to 6TB; other drive formats do not fit.

Performance reality: link rate versus file speed

The enclosure’s USB link is rated up to 5Gbps while SATA III is a 6Gbps internal bus. The lower USB ceiling governs; actual throughput is lower and depends on media, host, workload and UASP support.

  • Large sequential files usually transfer faster than folders containing thousands of small files.
  • HDD mechanics, SSD cache exhaustion, encryption, antivirus scanning and thermal throttling can dominate the result.
  • UASP, TRIM and S.M.A.R.T. require compatible drive, bridge, host controller, operating system and software; a feature label does not force every host to expose it.
  • Backward compatibility means operation at the slower negotiated link; it does not preserve the headline speed.

Use scenarios

Portable SATA SSD

Turn a spare 2.5-inch SATA SSD into compact external storage for documents and project files.

Old laptop drive reuse

Give a healthy 7mm or 9.5mm laptop SATA HDD/SSD a second role after checking for encryption and file-system compatibility.

Console or router storage

Use only if that host supports USB mass storage, the drive capacity and the required format; reformatting can erase existing data.

Backups and archives

Build a scheduled backup target, then keep a second independent copy. An enclosure is storage hardware, not a complete backup strategy.

Drive inspection

Read a removed drive on another computer when the drive is electrically healthy, unlocked and formatted in a file system the host understands.

The compact enclosure and detachable lead are travel-friendly; pack the drive only after safe ejection and protect the cable ends from strain.

Setup and usability guidance

  1. Step 1: Disconnect power and USB. Confirm the bare drive is the supported SATA form factor and has no protruding rails, caddy or adapter attached.
  2. Step 2: Open the enclosure, align the drive’s 7+15-pin SATA connector and slide it straight into the socket. Never rock or force the thin plastic tongue.
  3. Step 3: Fit the supplied EVA spacer for a thinner 7mm drive when applicable, then close the housing without trapping the cable or pressing on the drive.
  4. Step 4: Connect the supplied data cable directly to a suitable host port. Avoid unpowered hubs during first detection.
  5. Step 5: If the drive is new, open the operating system’s disk utility, verify the correct disk by capacity/model, then initialise, partition and format it. Formatting erases data.
  6. Step 6: If the drive already contains data, do not initialise or format it merely because the host prompts you. First check encryption, file system, health and the original machine.
  7. Step 7: Before disconnecting, finish all transfers, eject or safely remove the volume in the operating system, wait for activity to stop and then unplug or switch off.

Critical distinction: “Not visible in File Explorer/Finder” does not automatically mean hardware failure. A blank, offline, encrypted, unsupported or unmounted disk can appear only in the system disk utility.

Migration, cloning and data-recovery planning

Before migration

Back up irreplaceable files separately. Record encryption/recovery keys and confirm source and target health before changing partitions.

Cloning is software-driven

This enclosure exposes one drive; it has no verified standalone clone button. Use trusted software and verify the copy before erasing the original.

Booting is not guaranteed

External boot depends on the computer firmware, operating system, security policy, partition scheme and licensing—not just the enclosure.

Recovery has limits

An enclosure cannot repair failed heads, damaged NAND, controller faults, corrupted encryption or severe file-system damage. Repeated retries can worsen a failing drive.

Compatible devices and systems

Listed/verified class: Windows, macOS, Linux and ChromeOS; live media illustrates PC, router, PS4 and TV use subject to each device’s supported file system and capacity.

Computers

Most modern systems support USB mass storage, but file-system write support differs across Windows, macOS and Linux.

Phones and tablets

A matching connector is insufficient: the mobile host must support USB OTG/mass storage, the chosen file system and the enclosure’s power demand.

TVs, routers and consoles

Check the device manual for USB generation, file system, partition table, maximum capacity and whether formatting is mandatory.

Hubs and adapters

An extra hub or converter can reduce speed or power stability. Test directly on the host before diagnosing the enclosure.

Illustrated hosts are conditional examples; their USB-storage policy, file system, capacity and power budget determine actual compatibility.

What this product does

  • Houses one 7mm or 9.5mm 2.5-inch SATA HDD or SSD and connects it to a USB-A host through a detachable cable.
  • Provides the verified path: SATA III, 7+15-pin to Detachable 30cm USB 3.0 Micro-B to USB-A cable.
  • Supports the exact drive boundary: 2.5-inch SATA I/II/III HDD or SSD, 7mm or 9.5mm high.
  • Uses Black plastic enclosure with internal EVA pads and ASM1153E on current official UGREEN product material.
  • Exposes the drive to a compatible host for normal file access, formatting, backup, migration or supported cloning software.

What this product does not do

  • Not for 3.5-inch, M.2 SATA, M.2 NVMe, mSATA or IDE/PATA drives.
  • It does not include an SSD/HDD or add capacity by itself.
  • It does not guarantee the theoretical link rate as sustained file throughput.
  • It does not bypass passwords, BitLocker/FileVault encryption, permissions or unsupported file systems.
  • It does not repair a failing drive, replace a backup, provide RAID or perform unattended offline cloning.
  • It does not make a host support capacities, formats or game-install rules that the host manufacturer excludes.

What to do

Verify the exact drive

Read the drive label/data sheet for protocol, physical size, key and thickness before opening the enclosure.

Use the supplied path

Start with Detachable 30cm USB 3.0 Micro-B to USB-A cable. Connect directly to a known-good host data port.

Protect the thermal path

Install pads as directed, keep vents clear and allow airflow during sustained transfers.

Eject and keep backups

Safely remove before unplugging and maintain at least one independent copy of important data.

What not to do

Do not force connectors

Misaligned SATA or M.2 connectors can be damaged by surprisingly little force. Recheck orientation and protocol.

Do not format blindly

If a host asks to initialise or erase an existing drive, stop until you know why and have a verified backup.

Do not unplug during activity

Removing USB or power during writes can corrupt files, file systems or the drive translation layer.

Do not block cooling

Do not wrap, stack or operate on soft insulating surfaces during sustained transfer.

Warnings and limitations

Data first: an enclosure can expose a drive; it cannot guarantee the integrity of the data already on it. Keep independent backups before migration, repartitioning or firmware work.

Power: bus power depends on the host. If detection resets under load, remove unpowered hubs and use the supplied cable on a stronger direct port.

Heat: warmth can be normal, especially with NVMe. Stop use for smoke, burning smell, deformation, liquid ingress, repeated drop-outs or abnormal mechanical HDD sounds.

Handling: protect bare drives from electrostatic discharge; hold an SSD by its edges, avoid touching gold contacts and never move a spinning 3.5-inch HDD roughly.

Removal: wait for all writes, eject in the OS, allow the activity indicator to settle, then disconnect. Auto-sleep is not a substitute for safe removal.

Troubleshooting guide

No device at all

Disconnect, power down, reseat the drive and retest with the supplied cable directly on another known-good host data port. Verify the drive protocol and orientation.

Enclosure detected, no volume

Open Disk Management/Disk Utility. A new disk may need initialisation; an old disk may be offline, encrypted or use an unsupported file system. Do not erase valuable data.

Slower than expected

Confirm negotiated USB mode, remove slow hubs, use the supplied cable, test a large file and check SSD/HDD health, cache and temperature. Link rate is not file speed.

Disconnects under load

Check cable seating, direct-port power, thermal-pad placement and airflow. For SKU 50422, use the supplied 12V/2A adapter. Stop if the drive reports health errors.

Read-only or permission errors

Check write protection, ownership, encryption and file-system support. macOS and Windows do not natively write every file system used by the other.

Console/TV asks to format

That host may require its own partition and file system. Formatting erases the drive; move needed data elsewhere first and review the host manual.

Package contents

1 × UGREEN 30848 enclosure, 1 × 30cm USB 3.0 Micro-B-to-USB-A cable; SSD/HDD is not included

No host computer, phone, tablet, console, TV, router, SSD/HDD, cloning software or data-recovery service is included unless explicitly named above.

Research reconciliation: Exact current UGREEN source and live media confirm the detachable Micro-B/USB-A design, tool-free fit, 5Gbps, 7/9.5mm SATA support and EVA pads. Capacity differs across regional spec tables; the India handle/gallery’s 6TB figure is retained rather than inflating it.

Product-specific FAQ

What is UGREEN 30848 made to do?
Houses one 7mm or 9.5mm 2.5-inch SATA HDD or SSD and connects it to a USB-A host through a detachable cable. It is an enclosure/bridge, not a drive; storage media is not included.
Which drives fit?
2.5-inch SATA I/II/III HDD or SSD, 7mm or 9.5mm high. Not for 3.5-inch, M.2 SATA, M.2 NVMe, mSATA or IDE/PATA drives.
Does it support both SATA and NVMe?
No NVMe or M.2 drive fits this enclosure. It is for the stated 2.5/3.5-inch SATA drive format only.
What is the real maximum speed?
The enclosure’s USB link is rated up to 5Gbps while SATA III is a 6Gbps internal bus. The lower USB ceiling governs; actual throughput is lower and depends on media, host, workload and UASP support. Link-rate labels are theoretical and should not be read as a guaranteed benchmark.
What capacity is supported?
Up to 6TB on the exact India handle and live gallery; some newer regional tables conflict, so 6TB is the conservative model-specific limit used here. Capacity support does not guarantee that every TV, router, console or old operating system can address or format the same size.
Will a new drive appear immediately?
The enclosure can be detected while a blank drive still has no volume. Use the correct disk utility to initialise, partition and format a new drive. Double-check the disk identity because formatting destroys existing data.
Can it clone or migrate my system?
It provides external access to the installed drive but does not perform standalone cloning. Use reliable cloning/backup software, confirm the target has sufficient usable capacity, keep the original untouched until verification and handle encrypted/boot volumes according to the OS vendor’s guidance.
Can I use it with a console, TV or router?
Possibly: Windows, macOS, Linux and ChromeOS; live media illustrates PC, router, PS4 and TV use subject to each device’s supported file system and capacity. The host may require a specific file system, partition scheme, capacity, power budget or dedicated “extended storage” format. Those rules can erase the drive and are controlled by the host, not by the enclosure.
Why is the drive not detected?
Power down and reseat the drive, confirm its protocol/form factor, try the supplied cable directly on another suitable host port, and inspect Disk Management/Disk Utility rather than only the file browser. Do not format an unknown drive with valuable data.
Is warmth normal, and how should I disconnect?
A drive and enclosure can become warm in long transfers. Keep ventilation clear, do not cover the housing, and stop for abnormal smell/noise or repeated disconnects. Always eject the volume and wait for activity to stop before unplugging.
What is included?
1 × UGREEN 30848 enclosure, 1 × 30cm USB 3.0 Micro-B-to-USB-A cable; SSD/HDD is not included.

Exact-model check before ordering

Match SKU 30848, the supported drive protocol/form factor, capacity guidance, supplied cable and the host’s data capability. Similar-looking UGREEN enclosures can differ in SATA versus NVMe, USB-A versus USB-C, power requirements and speed ceilings.

Simply perfect. Got this for my Xbox One as all other enclosures refused to detect my hard disk. This one worked like a charm on the first go and the tool-less installation was the cherry on top. Transferred my entire game library from internal to this of about 200GB in just under 20 minutes with a constant speed of 110Mbps
