Manufacturer description
The RAOYI 256GB USB C Flash Drive solves the cable-free transfer problem with two connectors on one aluminum body: a USB-A 3.0 end for your MacBook dock, laptop, or desktop, and a USB-C end for Android phones and tablets that support OTG. You get 256GB of capacity for offloading 4K video, photo libraries, and music without paying for more cloud storage. RAOYI rates the drive at 90-100MB/s read and 20-30MB/s write, so pulling a folder of vacation footage off your phone takes minutes, not an afternoon.

SpecPicks Verdict
SpecPicks scored RAOYI 256GB USB C Flash Drive using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. RAOYI's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will this work with my iPhone?
The USB-C end works on USB-C devices with OTG support. RAOYI lists USB-C smartphones, MacBooks, computers, and tablets as compatible; it does not include a Lightning connector, so older Lightning iPhones are not supported.
How fast does it actually transfer files?
RAOYI rates it at 90-100MB/s read and 20-30MB/s write over USB 3.0. Reads are quick for opening or copying files off the drive; writes are slower, so large backups take longer than on a high-end drive.
Does it work on both Mac and Windows without reformatting?
Yes. The 256GB drive ships formatted as exFAT, which macOS and Windows both read and write natively, so you can move files between the two without reformatting.
Is 256GB enough for phone backups and 4K video?
256GB covers full photo libraries, music collections, and hours of video. RAOYI positions it for work and travel backups of photos, music, and video files without using a cable or iCloud.
Is it durable enough to keep on a keychain?
The shell combines premium aluminum alloy and ABS plastic for strength and impact resistance, and there is a loop on the side sized for a keyring so the drive stays attached rather than loose in a bag.
