Overview

The Buffalo HD-LX8.0U3D is a desktop external hard drive that packs 8TB of storage into a compact, upright enclosure. It connects over USB 3.0, offering a maximum transfer rate of 5.0Gbps, and is designed for users who need to store large volumes of photos, videos, and backup data. This is a stationary drive, powered by an AC adapter rather than the USB bus.
A standout feature of this model is its hardware encryption capability. The drive handles encryption at the hardware level, so you don't need to rely on PC-side software to protect your data. This makes it a solid choice for offices handling sensitive information or individuals who want an extra layer of security for their files.
In the market, this drive sits in the entry-to-mid tier of large-capacity external HDDs. With 8TB, it's on the higher end of what you'll find in consumer external drives, making it a practical option for whole-system backups or as a nearline archive. It's a straightforward, no-frills storage solution for users who prioritize capacity and security over portability.

Compatibility Guide

The HD-LX8.0U3D supports Windows 10, RT 8.1, RT, 8.1, 8, 7, and Vista, as well as Windows Server 2012R2, 2012, 2008R2, 2008, 2003R2, and 2003. On the Mac side, it works with OS X 10.11, 10.10, 10.9, and 10.8. This broad OS support means it can be shared across multiple machines without much hassle.
Connectivity is via USB 3.0 and USB 2.0. On a USB 3.0 port, you'll get the full 5.0Gbps interface speed, while older USB 2.0 ports still allow operation at up to 480Mbps. The included USB 3.0 cable (A to B, 1m) is all you need to hook it up to your PC.
Power is supplied through an AC adapter (AC 100V 50/60Hz), with a maximum power consumption of 18W. This AC-powered design ensures stable operation, especially during sustained read/write sessions. The package includes the USB 3.0 cable, AC adapter, and a user manual.

Product Info

This model was released in December 2016. Its physical dimensions are 39mm wide, 123mm high, and 189mm deep (body only, excluding protrusions), with a weight of approximately 1kg. It carries an energy efficiency rating of C category (0.00091), complies with Japan's Green Purchasing Law, and meets RoHS standards.
In terms of market positioning, this is a mid-tier external HDD aimed at bulk data storage. The 8TB capacity targets users who archive large media libraries or need a reliable destination for full-system backups. The hardware encryption feature sets it apart from standard external drives, adding a security layer that's uncommon at this price point.

Best Use Cases

  • Creative professionals archiving large photo and video libraries. The 8TB capacity comfortably holds RAW image files and 4K footage, and the AC-powered design suits a fixed desk setup. It's not for those who need to carry their storage on the go.
  • Users who want a dependable target for regular full-system backups. The large capacity and stable AC-driven operation make it a reliable repository for system images and file history. People who prefer a bus-powered, pocket-sized drive should look elsewhere.
  • Office workers handling confidential or personal data. The hardware encryption protects the drive's contents without requiring separate software on each connected PC. However, if you'd rather not deal with encryption setup and management, this feature may go unused.

Things to Consider

Being a 2016 model, this drive doesn't support newer USB standards like USB 3.2 or USB4. Transfers are capped at USB 3.0 speeds (5.0Gbps), which is noticeably slower than modern external SSDs. If you frequently move very large files, an SSD would be a better investment despite the higher cost per gigabyte.
The AC adapter requirement makes this a stationary device, so it's not suitable for travel with a laptop. For portability, a bus-powered portable HDD or SSD is the better choice. Additionally, 8TB may be overkill for many users; if you only handle a few gigabytes of data, a smaller and cheaper drive would suffice without the extra capacity going to waste.

FAQ
