Transcend RDF5 Review
Transcend is a global brand that was first found in Taiwan back in 1988. They are mostly known for their multimedia and digital storage products. And they offer both consumer grade and industrial solutions. That also includes memory card readers. And today we reviewed one of those, the Transcend RDF5. The RDF5 is their most basic and highest rated memory card readers. And there is definitely a reason for that as it provides an inexpensive option to read MicroSD and SD cards.
- Dimensions: 56×24×8.9 mm / 2.2×0.9×0.4″
- Read speed: 90 MB/s
- Write speed: 60 MB/s
- Slots: SD, microSD
- Connection: USB 3.0
The Transcend RDF5 is a pretty sleek low-profile memory card reader. As you can probably expect, it’s fully made out of plastic. You can however choose between multiple colors: black, white and pink. It’s also a pretty small memory card reader which is great for laptops. The USB plug is attached to the body so you can insert it right to the USB port. Preferably a USB 3.0 port as it transfers data faster.
Overall the build quality is okay. There’s nothing really impressive about it, the plastic case does feel kind of thin. Transcend has even included a cap cover for the USB plug, which is a nice addition but not that necessary in my opinion. Oh and there is also a small LED indicator that lights up in blue when you insert a memory card. And it will start flashing once you actually use it.
According to Transcend, the RDF5 has a maximum read speed of 90 MB/s and write speed of 60 MB/s. These rates are mentioned while using a Transcend 128GB UHS-I card. Which means that the rates can change based on the memory card you use. In my case I tested that with the SanDisk Extreme 90MB/s U3 V30 64GB SD card. The maximum read speed of the card is 90 MB/s and the write speed is 40 MB/s. And the results were pretty accurate.
I transferred a 659 MB folder from the memory card to a computer within 7 seconds. The average read speed was around 87.2 MB/s with a peak at 91.6 MB/s! So it definitely passed the read test. And yes I used a USB 3.0 port. Out of curiosity, I also did the same test with a USB 2.0 port and I ended up having to wait around 4 times longer.
I took the same 659 MB folder and this time transferred it from the computer onto the memory card. It took around 13 seconds with the average write speed at 39 MB/s and a peak at 43 MB/s. Which is pretty surprising as SanDisk rates their max write speed at 40 MB/s. With a USB 2.0 port, the average write speed was just 14 MB/s. So you can see the speed difference there.
The Transcend RDF5 is a fantastic inexpensive memory card reader for the average user. It’s fast enough to use most memory cards at their maximum speed, as long as you aren’t a professional of course. So I can recommend it for anyone that just needs a small memory card reader to access their photos etc. Just make sure you always use a USB 3.0 port!
