Transcend RDF5 USB 3.0 čtečka paměťových karet SDHC (UHS-I)/SDXC (UHS-I)/microSD
A compact USB 3.0 card reader that pulls data off SD and microSD cards quickly at a friendly price.
The Transcend RDF5 delivers surprisingly fast transfer speeds for very little money, making it a solid gift for photographers and laptop users. Its somewhat thin housing and side-loading SD slot are the main drawbacks.
Reasons to buy
- Fast USB 3.0 transfers: up to roughly 90–95 MB/s read with a good UHS-I card
- Compact and light (about 8.9 mm thick, 18 g) — slips easily into a bag or pocket
- Supports SD, SDHC, SDXC and microSD/SDHC/SDXC (UHS-I), with backward compatibility to USB 2.0
- Free RecoveRx recovery software and a blue LED that shows card activity
Reasons to consider
- Casing feels thin and hollow and has some play in the USB port
- The SD card sticks out sideways and can block an adjacent USB port
- No protective caps for the card slots; the included USB cap is easy to lose
What it is
The Transcend RDF5 is a dual-slot USB 3.0 card reader (USB 3.1 Gen 1) with a Type-A connector. It reads both SD cards (SD/SDHC/SDXC) and microSD cards (microSD/SDHC/SDXC), including the faster UHS-I variants. Note that you can't use an SD and a microSD card at the same time, so direct card-to-card copies aren't possible.
Performance and use
In independent testing the RDF5 reached read speeds around 95 MB/s and write speeds up to roughly 60–91 MB/s depending on the card — within a few MB/s of the fastest readers. Users report smooth transfers (for example 72 GB in about 14 minutes). The trade-off is build quality: the plastic feels thin and the reader has some wobble. For the price, though, it remains strong performance per dollar.
Who is it for?
A handy, affordable gift for photographers, videographers and laptop users who regularly offload photos or files from memory cards and don't want to carry a separate adapter.
FAQ
Does the RDF5 work with older USB 2.0 ports?
Yes. It uses USB 3.0 for top speed but is backward compatible with USB 2.0 — though transfer speeds will be lower.
Can I use an SD and a microSD card at the same time?
No. The RDF5 supports only one card at a time, so you can't copy directly from one card to the other.
