This article covers エレコム USBメモリ 64GB USB3.1 & USB 3.0 ノック式 ホワイト MF-PKU3064GWHF (× 3).

Overview

The ELECOM MF-PKU3064GWHF is a straightforward USB 3.1 Gen1 flash drive designed for convenience and reliability. This 3-pack bundles three identical 64GB drives in a crisp white finish, making it easy to keep one at home, one in the office, and one in your bag as a spare. At just 57.7×20×10.5mm and 11g per drive, the MF-PKU3064GWHF is extremely portable. The standout feature is its knock-type (push-to-extend) connector: slide the side button forward, and the USB Type-A plug pops out; push it back, and the plug retracts automatically. There are no caps to lose, and you can operate it one-handed — a small but meaningful quality-of-life improvement for anyone who frequently moves files between different PCs. The interface supports USB 3.1 Gen1 (5 Gbps theoretical max) and is backward compatible with USB 3.0 and USB 2.0. For typical office documents, photos, and small media files, the speed is more than adequate. Large video editing projects or continuous 4K video transfers would benefit from a higher-speed drive, but for everyday tasks this drive keeps things simple and effective.

Connectivity & Compatibility

The drive uses a standard USB Type-A connector, so it works with any device that has a USB-A port — desktop PCs, laptops, game consoles (PS5, Xbox Series X/S), smart TVs, and car audio systems. On USB 3.1 Gen1 ports you get the full 5 Gbps speed; on USB 2.0 ports it will run at 480 Mbps without issues. A notable limitation: modern ultra-thin laptops (MacBook Air M2, Dell XPS 13 Plus, etc.) often only have USB-C ports. You will need a USB-C to A adapter or a hub to use this drive with those machines. The drive comes preformatted as NTFS, which is plug-and-play on Windows but requires reformatting (e.g., exFAT) for macOS and some game consoles. PS5 and Xbox Series X|S can use it for saved data backups, but not for game installations.

Product Info

The MF-PKU3064GWHF series launched around 2023 and remains widely available. ELECOM offers it as a single unit as well as in 2-pack and 3-pack bundles. The 3-pack reviewed here typically retails for ¥10,752 on Japan (tax included), working out to roughly ¥3,584 per drive — a modest savings over buying three individually. Warranty is 1 year from purchase, backed by ELECOM's domestic support in Japan. No case, cap, or lanyard is included; the packaging is minimal. Positioned as an entry-to-mid tier product, it doesn't promise blazing speeds but delivers reliable performance and excellent usability for daily tasks.

Best Use Cases

Office workers and students: For transferring documents, PDFs, and presentation files in the 10–500 MB range, this drive is perfectly adequate. 64 GB provides generous storage for weeks of coursework or project files. The push-out mechanism makes quick plugging/unplugging easy. Not ideal for video editors or developers who routinely move tens of gigabytes each day — those users should look at USB 3.2 Gen 2 or SSD-based solutions for higher throughput. Remote workers with multiple workstations: Having three identical drives lets you keep one at your home desktop, one in your laptop bag, and one as a spare. You never have to worry about forgetting the only drive at the office. Again, if you regularly transfer 4K video or large databases, consider a faster alternative. Casual gamers for save backups: The drive works for backing up game screenshots, save files, and small mod archives. PS5 and Xbox Series X users can use it for save data exports via the console's USB-A ports. Not suitable for game installation or for heavy read/write workloads — frequent rewriting shortens the lifespan of flash memory. For game libraries, an NVMe external SSD is the proper tool. Beginners or seniors new to PCs: The cap-less, one-handed operation eliminates the frustration of losing small caps. If you find traditional USB drives fiddly, the knock mechanism is genuinely easier to use. The only caveat is long-term mechanical wear of the sliding button — under normal usage it will last years, but heavy repeated use may eventually loosen the spring action.
