Great sd card

It's about one year later I'm entering this review. The sd card has held up. I have no complaints. If was used to install a map for my head unit's navigation it is held up

Works with Roku 3

Reviewed in the United States 🇺🇸 on February 5, 2021

Size: 4GBVerified Purchase

If you are looking to speed up your channels on the Roku 3 then this micro sd card will work. It is older technology and doesn't have much memory but it appears that Roku likes that. ( I put a 32gb class 10 in the Roku and it doesn't even recognize it) It doesn't seem to speed up the loading of our YouTube TV. However Disney+, HBOMax, and Apple TV+ all show much faster loading with this card. The formatting takes less than 5 minutes. If you have a few minutes, after formatting, go to each of the channels that you want to load on the card and let them load for the first time. I went back and checked them out and found the channels loaded faster, except YouTube TV. (somebody more tech savvy than me could probably explain that) I gave it 5 stars because it does what I want it to do.

Kaput Goes the SD Card

Reviewed in the United States 🇺🇸 on September 24, 2014

Size: 32GBVerified Purchase

I purchased the ADATA AUSDH32GCL4-RA1 MicroSDHC 32GB Class 4 + SD Adapter, Black, in 2012.

I bought the ADATA MicroSDHC card to use in my cellphones (Motorola and Samsung devices), and my MP4 Player (ZEN X-FI 3 Player). I mostly stored music on the SDHC card, with a few other pictures and files here and there.

The SD card was working perfectly fine, until about a year ago when it decided to go kaput. By the time the SD card stopped working, it was in it's third device, the ZEN X-FI 3 MP4 Player. The SD card was a little more than half full, so it wasn't overloaded. My MP4 player stopped reading the SD card, as well as both of the phones, in which I attempted to use in those devices. From what I noticed, all three devices could not read the SD card, since I was unable to access any of the files on it. The devices froze up as soon as it tried to read the SD card, and I ended up having to restart each device without it to get the device working again. When I plugged the devices into the computer, the removable drive appeared, showing up as it should. I double clicked on the removable drive and received an error message that said, "all of the files were corrupt and were not recoverable." Of course, I tried to recover the files anyhow, but had no luck.

I'm giving this product three stars because even though it disappointed me, it wasn't a bad price and I am pleased with the other ADATA products I purchased before. That, and I believe it may be partially my fault that it stopped working. I don't think MicroSDHC cards are made to transfer from one device to another, or should I say several devices for that matter. Anyway, the product cost very little and it lasted for a year. I have received several other ADATA products that are great quality, so I'm going to guess this one just stopped working due to wear and tear of the user. So, I can't hate on it too much. I do, however, recommend SanDisk MicroSDHC cards over ADATA's. I used the SanDisk SD card just like the ADATA's, and it is still working perfectly fine two years later.

Not Impressed

Reviewed in the United States 🇺🇸 on April 13, 2011

Verified Purchase

I bought this card based upon the first review (second review had not been posted when I purchased). Like the second reviewer, I am disappointed with the speed. While the card does meet its class 4 rating, I was expecting much better write speed based on the first review and my previous experience with a 4GB A-Data Micro SD card.

I used the popular h2testw program to test the write speed and the result was only 4.33 MB/s. My testing procedures were sound. All other programs, including anti-virus, were shut down and I tested a SanDisk Mobile Ultra 16GB Class 4 card under the exact same conditions and got 9.87 MB/s write speed. All tests were run multiple times with the same results. If you don't mind 4.33 MB/s write speed, this card is fine, but if you want fast write speeds, look elsewhere.

I was hoping to find a 16GB micro sd card that is as fast as the SanDisk Mobile Ultra for less money, but so far, no luck.

Edit 4/12/2012: Upgraded to 3 stars based on comments that pointed out card does meet specs.

32GB Chips - A Must Have with your SmartPhone

Reviewed in the United States 🇺🇸 on August 16, 2013

Size: 32GBVerified Purchase

I always look for the ones with the adapters because you need those when you don't have your transfer cable to upload your photos. It's good for a gift as well. I gave on to my friend for his phone & it made a big difference especially when watching videos.

<strong>I would recommend this as good grab gifts or just a gift to your SmartPhone.</strong> But you definitely need it with any and all phones except the Samsung 3/4 because those already have 16GB and can be boosted to a 64GB SD chip.

6.7MB/sec Write speed - 8.5MB/sec read speed

Reviewed in the United States 🇺🇸 on October 1, 2011

Verified Purchase

I bought this one to store movies (MKV/MP4 1GB - 1.5GB) for viewing on an internet tablet. I've been using this for about 6 months now. I have not experience any data corruption yet. It gives me a write speed about 6.7MB/sec and read speed about 8.5MB/sec. It takes about 40 minutes to fill up the cards with MKV/MP4 movies.

I used the following hardware/computers for reading/writing this card: Acer i3/Win7 laptop with built-in SD card reader, Dell Quad Cord/Vista desktop with a multi-reader, a Sandisk SD/MS reader, a generic micro SD readers.

I'm pretty satisfied with such a class-4 SD card performance.

Solo funcionó 33 días, perdí mi dinero.

Reviewed in Mexico 🇲🇽 on August 27, 2018

Size: 8GBVerified Purchase

La tarjeta se daño justo al mes 3 días de haberla comprado, funcionó muy bien hasta el día que se daño, de hecho la utilice en un moto E4, no perdí mis fotos y videos ya que los había respaldado pero me borró algunas apps, ya que la utilizaba como memoria interna. De hecho el teléfono también empezó a fallar, la tuve que retirar, la intente formatear pero no se pudo, me daba un error de partición de memoria.
El coraje que me dio, es que justo la ventana de devolución había cerrado hace 3 dias. No volveré a comprar esta marca, ni a este proveedor. Perdí tiempo y dinero.
