Great little adapter for writing Raspberry Pi boot images to MicroSD

As always, huge fan of Anker. Years ago SanDisk used to include a USB MicroSD adapter with their cards... I have 2 of them laying around, but they were 2.0. Lately I have been doing a lot of image writes for the Libre LePotato (Raspberry Pi type board) testing images on top of testing images. Constantly writing those at 2.0 was taking longer than it should have, so I went searching for a 3.0 adapter. Using Win32DiskImager, I shaved off almost a minute in writing to my Lexar 633 card. At 2.0 I was averaging about 5 minutes per boot image and up to 7 minutes using an old MicroSD card. So getting that down in the 4 minute range was a plus. So all in all, I am happy with the 3.0

GREAT device to have, especially for the price!

I love this little guy! It's my second SD card-to-flash drive that I've had. The last one was cheaper, but it also looked the part. This one, on the other hand, looks professional, sturdy, and lightweight. It's small enough to stay out of the way, but big enough to look good in use. I don't use SD or MicroSD cards much any more like I did in college, but when my girlfriend's Android freaked out and corrupted her entire Micro SD card (I think that's what it was), I told her to let me borrow it. Using this card reader, I was able to plug her Micro SD into my computer, and, with the card still in the reader, ran a data recovery program that rebuilt all her photos that weren't corrupted. The reader got warm from the process (file recovery takes a couple hours and strains the drive that the data is on), but this little guy held in there like a pro. My girlfriend ended up not losing a single file. Like I said, I don't use card readers very often any more, but this is one of those things that I feel like everyone should have in case of an emergency, like needing to download photos after a digital camera's computer cable is lost, or when you need to get files off an Android. It's less than $10, and it's worth it to have one if and when it's needed right away. I've had good experience with the brand (Anker) in the past as well. They have really small, minimalistic packaging, but they also don't seem too "businesslike" as a company. At my old job we purchased several "4-Port Aluminum USB 3.0 Hubs", one for every web designer and web developer, since plugging hard drives and flash drives in and out was necessary many times per day. I don't recall ever having issues with any of them. Anyway, I'm actually going to go browse their other products now haha. Hope my review helped!

Works well. Plus product support is top notch!

When I inserted the new 64GB microSDXC card into a card reader and then plugged the reader into a freshly installed Win 10 laptop, I was surprised to only 32GB formatting option. I needed to use the card, so I formatted it anyway. My later investigation showed that the older reader was not compliant with SDXC format. This is why I did not see exFAT formatting option (and size larger than 32 GB) in the Windows formatting options. So I, naturally, went to Amazon.com and ordered this SDXC-compliant card reader. However, my Windows 10 still showed 32GB for the 64GB card even with this SDXC-compliant reader. This is where I called Anker support. After a short wait, Ashley from support started investigating the situation. Pretty quickly she found a link to SanDisk Knowledge Article about recovering "lost" memory from the card and emailed it to me. I downloaded the formatter from SanDisk and re-formatted the card to 59+ GB. I have bought Anker products in the past, but had not called their support. Now I feel pretty comfortable troubleshoot any issues -- their support is fo premium quality! P.S. If you are wondering why the 64GB card's actual size is just 59+ GB, Google this question for a detailed explanation. The gist is that Windows "interprets" "kilo" in "kilobyte" as the exponent value for the base of 2 rather than it's metric system's meaning as 1000 bytes. Following the same logic, it interprets Gigabyte to mean 2^30, i.e. 1024x1024x1024 = 1073741824 bytes. At the same time, SanDIsk interprets "Giga" according to metric system, and it's 64GB = 64,000,000,000 bytes. If you divide this value by 2^30, you will get 59.6 GB in the Microsoft system of measurement.

For less than $10.00, Anker delivers a fast, extremely portable reader

Exactly what I wanted/needed. I have been looking for an ultra portable, LOW-PRICED, high performance, SD card reader that is actually USB 3.0. Now I got it! For less than $10.00, Anker delivers a fast, extremely portable reader. The black glossy finished reader came in the standard Anker packaging. Out of the box, the reader is a plug and use device. Just place it into your USB port on your computer and the drivers will automatically install (Windows). When placing it into my Macbook Pro, I was able to use immediately. The reader itself is VERY small, lightweight, and portable. (I did not want to have to find a place in my laptop bag to fit a bulkier one). To display the size itself, see the photo I included comparing it to a SD card. I have only tested this product with SD cards, not Micro SD cards. Once you insert the reader, a blue light in the corner of the reader will signal on indicating that it is attached. Using two different SD cards with different speeds (SanDisk ExtremePLUS 32gb, SanDisk UltraPLUS 32gb), I transferred 10gb of data at one time. EACH of these transfers were extremely fast. Obviously the different card speeds displayed different times, however each were completed within minutes (whereas usually I would have started the transfer and got up to do something else). When ejecting the SD card, the blue light blinks indicating that you are doing so. The only con I have noticed is that when using the product on my Windows computer, I had to wait a minute before the SD cards would be recognized. Almost like the reader had to "warm up". I tried multiple USB 3.0 ports to see if this would change and it did not. This a minor con, however I wanted other consumers to be aware in case this happens to them. Note: This did not happen on my Mac. Overall this is a great little product. I would recommend to anyone who would like a portable SD card reader. Of course make note that this only supports SD and Micro SD, so if you are using a different kind, then this isn't for you. However, for most consumers this will be a great product that exceeds their needs.

Did a specialized job (3DS "Hardmod"), and as a bonus, read some SD cards afterwards. Excellent product.

Purchased for a New Nintendo 3DS XL "Hardmod." Was a bit dubious about the model number for this one, but this model (68ANREADER-B2A) does work. I know the guide you are probably looking at says 68UNMCRD-B2U, but I did the entire mod using this model number. It works. I cancelled my order twice trying to get the "correct" model before giving this one a chance. If you're running into issues with this application, before blaming the reader, shorten the internal and external DAT, CLK, and CMD lines as much as possible. Ground is ground. It seems the voltage drop across any extra inches of wire is enough to stop differentiating between 1s and 0s. Not the reader's fault. It did the job I asked of it, and have even managed to use it in a more conventional way since. Anker makes quality products, and this is no exception.

1 of the best & most affordable USB 3.0 readers... :)

This thing is great! :D All I got to do is plug it in & go. It can do 2 cards at once if need be, but the SD card will be the bigger of the 2 & since the slots are so close together that may make getting the Micro SD card out kinda tricky. An interesting thing I noticed about this is the SD card fits backwards (looking from the front of the reader) while the Micro SD card fits the opposite way. Perhaps that has something to do with 2 cards at once compatibility. Not sure on speed. This does have a fast speed for my cards I use with it, but that depends on the speed of card &/or whether or not it's in a USB 3.0 port. If you have a fast card & this is plugged into a USB 3.0 port, it'll fly along. On the other hand, if the card isn't very fast or the card is fast but the reader is in a USB 2.0 port, the speed will be reduced. I noticed a similar thing happen on my USB 3.0 compliant flash drive... when I plugged it into a USB 3.0 port, it was much faster than it was in the 2.0 ports. Interesting how that works that way... :) Bottom line, this is a good brand & a great USB 3.0 compliant card reader. Fully satisfied & will consider this brand again in the future... :)

Just as fast as Lexar Professional Workflow 4 Hub Station

You know those Lexar 4 bay stations that are popular, but Lexar is largely being discontinued? Well on my Laptop I used 4 of these readers connected to Anker USB 3.0 4-Port Portable Aluminum Hub with 2-Foot USB 3.0 Cable (Carbon) . I still got the exact same speeds as my Lexar station, in a much smaller format, and I never needed a power supply for it. My SanDisk 90MB/s read cards read at full speed with 3 cards connected, but with the 4th they drop down to about 70MB/s. This is the SAME as the Lexar station, so I figure it is just maxing out the bandwidth of the USB 3.0 port (about 280MB/s total). I do wedding videography, and instead of sitting in front of my PC when I get home offloading all my footage when all I want to do is crash, I have this connected to my laptop and is all transfered to the laptop drives and an external drive by the time I get home. Such a huge time saver! When I get home I have the footage already organized on the external HDD, and just plug that one drive into my main PC to offload there as well as a backup drive that I feel comfortable leaving on it's own as I already have 3 total copies if something goes wrong. In the morning I have 5 total copies of a wedding waiting and ready for me! (4 on HDDs, 1 the original SD Cards). Did someone just call me OCD?

Fast, durable, affordable SD reader. Another quality Anker product.

I do dance photography as a hobby and shoot primarily in raw so I have more control in correcting lighting/color/etc... Because of this my photo files are usually very large and transferring via most cameras built in USB ports is painfully slow. Luckily Anker has this little gem. Transfer speeds are very, very good for USB 3.0 - I consistently can get between 80-90 MB/sec when reading. When transferring 64 to 120GB of pictures, this speed makes a huge difference. It's also very compact and does not have a cable which would eventually wear out. The build quality is excellent - small, solid, easy to throw in my camera bag so I have it with whenever I might need it. Plus, at it's price, if it does go missing it's affordable to replace. If you need a fast, reliable SD/MicroSD card reader, this is the one. More generally speaking on Anker, they've become one of the most reliable computer/camera accessory companies in the business. I first started using their product 4 years ago and they're now my default company for most electronic purchases. Their products are well made, well designed and their 18month warranty can't be beat. I purchased this product directly, received no discount, am not affiliated with Anker and was not asked to leave this review. It's just a well-made, well-designed reader, buy it, you won't be disappointed

Great Reader, Fast speeds through USB 3.0

Great Card Reader, Fast speeds. If anyone else would like me to do further testing please comment. I use this card for all my Micro SD and SD Cards and it transfers great with USB 3.0. I've gotten remarkable results with this and the Lexar 1000x SD Card for my camera. If you want full speeds for your card without a reader as a bottleneck, definitely go with this one and it's at a budget price. Big fan of Anker Customer support as well as they have replaced a charger from me nearly 16 months later from a previous purchase.

Compact, Fast, Great Price

Speed: At this price I was skeptical that this thing was really USB 3.0. However, I tested it with a SanDisk Extreme Pro 64GB SDXC UHS-I Memory Card (SDSDXXG-064G-GN4IN) and as you can see in my attached image it easily maxed that card out at the rated 95mbps. I even went back and tested this thing by plugging it into a USB 2.0 port and saw the sequential speed cut roughly in half. However, it should be noted that all of the non-sequential speeds were basically the same between USB 2 and 3. While a lot of people would say that random read/write performance is more indicative of a drive’s real-world performance that isn’t a true with the use case of SD cards. Most of the time you are simply writing and reading large blocks (like transferring a bunch of images), so I think you really would notice the speed difference between USB 2 and 3 in this case. I’m very happy with the speeds this device enables. Size: This thing is about as tiny as it could be. I have an image of it next to a SD card and you can see that there is little wasted space. However, it is pretty fat around the USB plug, so it may block another USB port if they are close together like USB ports are on most laptops. OS Compatibility: I have used this device with both OS X and Windows 10 both worked immediately without the need to manually instal drivers. Price: At $10 this is a great deal. Nothing more to say about that! Conclusion: There are few product I would recommend without a single reservation and this is one of them. I have a bunch of other Anker products I have been impressed with and this is also an easy 5 star recommendation.
