Overview

The Acer UT300 USB Flash Drive 64GB (model: BL.9BWWA.589) is a portable storage device sold by Acer. It is available on Amazon.co.jp, sold by BIWIN Tech and fulfilled by Amazon. With a metal housing and dual USB-A and USB-C connectors, this drive offers a maximum read speed of 150 MB/s and supports USB 3.2 Gen 1 (5 Gbps). It is shock-resistant and dustproof, making it suitable for everyday carry and data transfer between devices.

Key Features

  • All-metal housing (aluminum) provides excellent heat dissipation and durability, protecting the internal components from physical shock.
  • Dual connectors: USB-A for traditional computers and USB-C for modern laptops, smartphones, and tablets—no adapter needed.
  • USB 3.2 Gen 1 interface delivers up to 5 Gbps theoretical bandwidth, with backward compatibility to USB 3.0 and USB 2.0.
  • Maximum read speed of 150 MB/s ensures fast file transfers for large documents, photos, and videos.
  • Compact and lightweight design makes it easy to carry on a keychain or in a pocket.

Compatibility Guide

The UT300 works with any device equipped with a USB-A or USB-C port, including Windows, macOS, ChromeOS PCs, as well as Android smartphones and iPads (via USB-C). For best performance, use a USB 3.2 Gen 1 or USB 3.0 port. When connected to a USB 2.0 port, transfer speeds will drop to around 30 MB/s. Note that macOS reads NTFS-formatted drives in read-only mode; consider exFAT for cross-platform use.

Ideal Use Cases

  • Carrying work files: Securely transport documents, presentations, and reports with the protection of a metal enclosure.
  • Expanding smartphone/tablet storage: Directly connect via USB-C to back up photos or videos.
  • Users who need both USB-A and USB-C compatibility: No need for dongles or adapters.

Upgrade Notes

As a standalone USB flash drive, this product does not affect PC upgrades. However, future systems with USB 4.0 or Thunderbolt 4 will not see higher speeds than USB 3.2 Gen 1 on this drive. For heavy write workloads, NAND type (MLC/TLC) can affect longevity, but Acer does not specify the exact NAND used. Regular backups and occasional formatting are recommended to maintain performance.
