USB 3.0 SD Card Reader - High Speed USB 3.0 Reader / Writer for all SD, SDHC, SDXC, Micro SD, Micro SDHC, Micro SDXC

It may not be the fastest USB 3.0 Multi Card Reader out there, but it does its job. To support this review, I did a mini un-professional test on my PC.My PC spec: CPU i5-3570k, Motherboard asus p8z77-v,16G RAM, Source and destination hard driver SSD Sansum 840 EVO 250G, Testing file 1.8GB MP4 file, SD card 32GB Transcend SDHC, MicroSD card Sansum 32GB Micro SDHC. The adapter was plunged into a 3.0 USB port during test.Test results:SD card: Writing test (Copying file onto the SD card), max speed 22MB/S, average speed 20MB/S. Reading speed (Copying file from SD card), max 92MB/S, average speed 89MB/S.Micro SD card: Writing test (Copying file onto the SD card), max speed 19MB/S, average speed 17.5MB/S. Reading speed (Copying file from SD card), max 74MB/S, average speed 71MB/S.Note: All the max speed is recorded during middle of the file transferring, while the transition is stabilized, not the top peak speed at the beginning of the transition. The average speed is an estimated speed, not statistical mean value results.Conclusion and final thoughts:Pros: Pretty good for a cheap USB3 card adapter, quite handy, I just use it as an flash driver. Of course the transferring speed not just depends on the adapter itself, but also on the hardware of the PC or Tablet connected to it, eg USB port type, CPU processing speed, RAM available etc.Cons: It can only read 1 card at a time, but not both SD and MircoSD, and for me the SD card is on priority. It is confirmed with the seller, this is designed to be so. But I guess it is not a big problem, one can always copy things to the PC or tablet first and duplicate the files to the other SD or MicroSD card.The adapter temperature did rise during the test, just finger warm but not unbearable hot, estimated less than 40°C.Overall, although I have only had it for couple of weeks (light usage), in my non-professional opinion, it is a very good adapter for general use with this price.

Yeah had problems reading SD's larger than 2 GB on my 2005 laptop, mates had tested my SD cards and external reader and we're convinced that the SD's + reader was naff, luckly I wasn't and purchased this item, had an idea it would be the firmware not seeing the larger cards!So far this item reads a 32 GB SD and a 64 Micro SD so happy days, looks OK and it's no to pricey compaired to the others on amazon that have a lead then the reader, didn't see the point of worrying about it sticking out of my dated laptop when it's a top draw gadget that gets used now and again then returned to top draw!Yes going to purchase a up to date laptop soon but for now I'm happy

I purchased this product purely for its Micro SD capabilities and when I tried inserting the Micro SD card nothing was registering with my laptop. The product arrived within an envelope with no instructions/troubleshooting guide. After several more attempts to no avail the product ended up on my floor for a couple of weeks deemed junk and a waste of time and effort sending back. But I decided to give the product one last go before it got chucked out for good. And I found that the Micro SD card has to be upside down and inserted with a little more force than you would expect to have to give a fragile little memory card.Overall great service on a great product(once you get the hang of using it) with nice transfer speeds with a low price tag to top it all off.

I had a multicard reader which had worked well enough for a while now. However I only use SDHC/microSDHC type cards now so some streamlining seemed to make sense. Given the fact that this is a USB 3.0 reader there is some future proofing too. I also wanted to use this (via an OTG cable) for use with a tablet that I now have as a sort of backup/transfer device. It has worked just fine on both the PC and tablets using an SHDC card. The fit is very snug and I'm not sure how easy it would be to get microSHDC cards in and out but some many come with adapters these days I'm using that approach. I also found that some cards were tighter than other. Good useful device at a reasonable price.

Delivery was pretty good, the item arrived three days after ordering.I've had a bunch of micro SD cards sitting around for a while now, not knowing what was on them. I had no other card reading device except for my old Galaxy S2, but decided to buy one of these for ease of use and portability. I needed USB 3.0 to ensure the fastest possible speeds and having a full sized SD card slot as well as a micro SD card slot is great. I use this as a USB flash drive and it's perfect for everyday usage.

On second use the device became too hot to handle and had to be removed from the port with piers. Port and (luckily) card still work fine so there is no doubt that the card reader was the culprit.

It worked fine on my PC Windows 10 but not on my Mac apart from that it does what it says on the packet

Works perfectly once I worked out the memory card goes into it upside down (for some reason). Note the photo shows the memory cards next to it and not inside it. Pehaps to conceal the need for cards to be placed in it upside down. Nevertheless it performs perfectlu and by this I mean it keeps a stable connection for an hour or more while data is being written. If it is not stable you will lose data on the memory card and probably destroy the memory card completely.No instructions with it at all.
