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.

• 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.
• Note: Mac OS X 10.6 or later — compatible but requires reformatting before use on macOS.
• Note: USB 2.0 hosts — backwards compatible, though transfer speeds will be limited to USB 2.0 rates.
• Note: 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. (1 TB, 2 TB only)
• 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. (4 TB only)
• 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. (4 TB only)
• 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.
