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.
Package contents
1 × UGREEN 70498 enclosure, 1 × 50cm USB-C-to-USB-A cable, 1 × user guide; 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 UGREEN India page and live gallery confirm the silver aluminum CM300 body, USB-C enclosure port, supplied USB-A cable, ASM235CM, 6TB and 6Gbps SATA path. The old page title’s “USB 3.1 Gen 2” is not presented as 10Gbps drive throughput.
Product-specific FAQ
What is UGREEN 70498 made to do?
Converts one 7mm or 9.5mm 2.5-inch SATA HDD or SSD into an aluminum external drive with a USB-C enclosure port. 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, up to 9.5mm high. Not for 3.5-inch, IDE/PATA, M.2 SATA, M.2 NVMe or mSATA 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?
Although the host-side USB generation is 10Gbps-class, the SATA III storage bus is limited to 6Gbps theoretical. Real speed is lower and depends on drive, host, file sizes, cable and UASP. Link-rate labels are theoretical and should not be read as a guaranteed benchmark.
What capacity is supported?
Up to 6TB, shown in the exact live gallery. 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 and Linux; exact media illustrates PC, TV, router and PS4 use subject to supported file system and console policy. 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 70498 enclosure, 1 × 50cm USB-C-to-USB-A cable, 1 × user guide; SSD/HDD is not included.
Exact-model check before ordering
Match SKU 70498, 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.
