ADATA HV620S 2.5" USB 3.2 Gen 1 Portable Hard Drive - Black
The ADATA HV620S 2.5" USB 3.2 Gen 1 Portable Hard Drive is a slim, gloss-finished external drive designed for professionals and everyday users who need dependable go-anywhere storage without bulk. At just 11.5mm thick on the 1TB and 2TB models, it slips easily into a briefcase or backpack and connects via USB 3.2 Gen 1 for fast, broadly compatible transfers. A scratch-preventing raised lip, blue LED activity indicator, and support for 256-bit AES encryption round out a practical package built around portability and capacity.
Why this product
Slim 11.5mm profile on 1TB and 2TB
The 1TB and 2TB models measure just 11.5mm thick, making them among the slimmest 2.5" portable hard drives available. The 4TB model is thicker at 21mm to accommodate greater capacity.
USB 3.2 Gen 1 with USB 2.0 backwards compatibility
It connects via USB 3.2 Gen 1 (USB 5Gbps) through a Micro-USB B connector and remains backwards compatible with USB 2.0 ports, so it works with older systems without an adapter.
256-bit AES encryption support
It is compatible with 256-bit AES encryption, giving users a path to secure sensitive files stored on the drive.
LED indicator prevents accidental disconnection
A blue LED lights up during read and write operations, making it easy to know when it is safe to unplug the drive and helping prevent data loss from premature disconnection.
Scratch-preventing raised lip design
A raised edge around the drive protects the glossy surface from scratches when it is laid flat on a desk or packed alongside other items.
3-year limited warranty
It comes backed by a 3-year limited warranty, providing multi-year coverage for everyday portable storage use.

- Windows 7, 8, 8.1, 10, and 11 — plug-and-play compatible out of the box.
- Linux Kernel 2.6 or later — supported without reformatting.
- USB 3.2 Gen 1 hosts — operates at full USB 5Gbps speed.
- Mac OS X 10.6 or later — compatible but requires reformatting before use on macOS.
- USB 2.0 hosts — backwards compatible, though transfer speeds will be limited to USB 2.0 rates.
- USB-C hosts — requires a USB-C to Micro-USB B adapter or cable, as the drive uses a Micro-USB B connector.
Best for
- Commuters and travellers who need large portable storage that fits flat in a bag — the 11.5mm slim profile of the 1TB and 2TB models adds minimal bulk.
- High-capacity needs on a portable drive — the 4TB option provides substantial storage in a 2.5" form factor for users with large media libraries or backup requirements.
- Users who value data security — support for 256-bit AES encryption gives a path to protecting sensitive files without needing a separate solution.
- Multi-OS households or workplaces — Windows, macOS (with reformat) and Linux Kernel 2.6+ are all supported, making it flexible across different systems.
- Buyers who want multi-year coverage — the 3-year limited warranty provides longer protection than many competing portable drives.
Trade-offs
- USB-C-only setups — this drive uses a Micro-USB B connector; a separate adapter or cable is required for hosts without a full-size or Micro-USB port.
- Ultra-slim bag packing — at 21mm thick and 230g, the 4TB model is noticeably bulkier and heavier than the 11.5mm 1TB and 2TB variants.
- Mac users who need plug-and-play — macOS requires reformatting the drive before use, which erases any pre-loaded content and requires extra setup steps.
- Workloads requiring SSD-class speeds — this is a traditional hard drive; it does not offer the sequential read/write speeds of an SSD-based portable drive.
The ultra-portable HV620S packs up to 4TB of external storage in a drive that's only 11.5mm thick. The design also shines with a mirror-like gloss, simple but elegant and fitting for dependable, go-anywhere storage that runs via fast USB 3.2 Gen 1. For all your content and with nearly universal device compatibility, the ADATA HV620S embodies smart design that increases capacity and performance while reducing physical space requirements.

From meeting rooms to treks in nature, the HV620S never gets in the way and always adds a touch of style to your storage.
Scratch-Prevention Design
A raised lip on the edge of the drive protects the surface from scratching when the drive is laid flat.
Sleek and Glossy
The sleek lines and reflective, smooth surface of the HV620S highlights its thin and elegant overall appearance. It is ideal for those who wish to maintain an aura of professionalism, or show off their technical savvy.
LED Indicator Shows Transfer Status
A bright blue LED lets you know when data is being read from or written to the HV620S. This helps prevent disconnection during read/write operations.
