Rytaki RY-304-A USB 3.0 Multi-Card Reader

Multi-Card: Rytaki RY-304-A is a USB 3.0 card reader for transferring files from several legacy and current memory-card formats. Its broad format list suits mixed camera-card collections, but the listing conflicts on whether multiple cards can be read at once.

At a glance

The format list includes SD, microSD, CompactFlash, Memory Stick, M2 and xD Picture Card.
The listing advertises USB 3.0 and transfer rates up to 5Gbps, while actual speed depends on the card and connected USB port.
A separate status LED is claimed for each slot, with a steady light when connected and flashing during transfer.

What to know before buying

The advertised maximum transfer rate is not a guaranteed real-world speed and depends on the card and host connection.

Listing details to confirm

The listing contradicts itself on simultaneous card use: a feature bullet says it can read and write five cards at once, while the description says multiple cards cannot be read at the same time. It also calls the device six-in-one and lists six card types, but says TF and M2 share a slot. The listing's title uses “5Gps” while details say “5 Gigabits Per Second” and feature text says “5Gbps.” Check the selected listing for the intended slot behaviour and card support. SD and TF slots are stated not to support SD4.0 or TF4.0, though compatible read/write is claimed.

Who is it for?

A good fit for

Photographers and computer users who need one reader for a mix of SD, microSD, CompactFlash, Memory Stick or older xD cards.
People using one of the listed operating systems who want a reader described as plug-and-play.

Less suited to

Buyers who need confirmed simultaneous transfers from multiple cards, since the listing gives conflicting instructions.
Users who require SD4.0 or TF4.0 support, which the listing says these slots do not provide.

Customer feedback describes the reader as working well, including a report that it reads both current and older formats. Functionality and reliability are mentioned positively, which is relevant for a reader marketed for multiple card types. Those impressions do not resolve the listing’s conflicting instructions about simultaneous card use, so that distinction matters if you plan to transfer from several cards together.
