Ultra 16GB Ultra Micro SDHC UHS-I/Class 10 Card with Adapter (SDSQUNC-016G-GN6MA)

Been using the SanDisk Ultra Micro SDHC Class 10 Cards for many years, starting with 8 GB, 16 GB, and more recently 32 GB. Always been reliable, and every new generation gets faster. Use mainly on Raspberry Pis. Only complaint is that if I order a 16 GB, I get a 32 GB delivered. Tried returning and replacing but still get 32 GB. Some users may think this is a good thing, but I regularly back-up my SDHC cards to my desktop (Mac), and backing up a 32 GB card obviously takes double the disk space, when I don't need the storage on the Raspberry Pi. Guess I'll have to start backing up individual partitions on the SDHC to avoid backing up lots of unused space.

SanDisk is a standard for data storage. I've never had a bad one. I chose the 16GB model for my Raspberry Pi Projects because it is enough storage for the Pi O/S I use, and this model is good for up to 80MB/s transfer speed. I've tried faster cards but no sense buying an ultra fast card if your reader will only read at a slower speed. I had the 98MB/s card but found it was generating some lockups...I don't know if the card was sending faster than the system could receive, but decided this card, at this price, is the perfect match of performance and price. I can plug in a hard disk drive if I need more storage; right into one of 4 USB slots on the Pi.

"This product was provided at a discounted price in exchange for my honest review." That being said, this flashlight set is pretty bright. I have purchased similar flashlights from Amazon, and this set is well made. It is securely packaged, and was shipped promptly. I would have gladly given this item a 5 star review, if the manufacturer would have provided a rechargeable battery for the mini flashlight in the set. Buried at the description it does say 1 x FREE Mini LED Flashlight (Battery not included; Uses one AA battery OR one 14500 3.6v battery), but it would be nice to have a 3rd rechargeable battery for the mini flashlight. It is a minor drawback for an otherwise bright and sturdy flashlight set. Pros: I like the sturdy construction, the belt clip and the lanyard provided, the 2 extra O rings provided, and the bright light the flashlight emits. Cons: The manufacturer should provide a rechargeable battery for the mini flashlight included in the set.

Over they years I have used many microSD cards in many devices - smart phones, tablets, cameras, even several Raspberry Pi SOCs (system on card) computers. Perhaps a year ago I acquired a desktop 3D printer and was pleased to see that it could operate in a standalone mode: no need to be connected to a PC or even use Wi-fi. All you need do is put the print file (type .gcode) on a microSD and use button, knob and little LCD screen to select the model and cause it to print. I took an old card from a Pi,reformated it to get rid of old stuff, and tried it. The printer didn't 'see' the card. Yet the PC could, it had copied the .gcode file to the cad! Huh? Turns out that the printer can not work with a card which has a partition, even if the partition is formatted the expected FAT32. All I needed was truly bare card, I didn't need a large capacity. So rather than really wipe the old card (carefully!) I just got this one. I removed the SanDisk 'security' software, didn't need/want it, loaded my 3D models and away it went. I've been using this card for some ime now - just had to make sure that I don't convert it to Linux file system - leave it at FAT32 if it is going to be used to feed the little 3D printer. My only complaint, and it probably isn't 'fair'. They sure make it hard to cut open the blister pack to get the card (and adapter) free. Perhaps SanDisk (and others) could put some dotted lines on the back of the cardboard indicating where it is safe to cut without running the risk of cutting the card or adapter? Going in though the side of the clear blister with (say) a box cutter or X-acto could be hazardous to your hand. Definitely not for one inexpreienced with sharp objects!

So this is more difficult to review, because I'm using these exclusively for booting SBCs (specifically RADXA SBCs). To be a 3 star product, it should (a) boot, (2) be stable, (3) summon a Djinn to grant me three wishes. TL;DR: Works for 2 of 3 expectations - no Djinn granted my wishes. Basic functionality: For my 3A, 4A, and ROCK Pi E, these worked great. I can boot reliably. Although I try to keep any writing to the MicroSD media minimal, when writing is required, it's reliable and fast [for a MicroSD]. Solidly a 3 star product. Why are these rated at 5 star? My Radxa SBCs have been the most finicky of all my SBCs (Libre, Raspberry, HardKernal). The fact that these MicroSDs work is worth 3 additional stars, but I only have 2 to give. Raspberry Pi 3, 3+, and 4B: These are flawless. HardKernal ODroid: These are flawless. Libre Le Potato / Renegade: These are flawless.

Good for the price

Item exactly as described and works well!

No se puede decir mucho de este tipo de productos, Es una tarjeta buena, bonita y barata, va muy rápida, funciona, no como las de otras marcas que mueren a los 2 usos, Tiene 14,8 gb de capacidad real, otras se quedan por los 14,4 gb. Siempre la detecta el PC a la primera. Es ideal para Raspberry pi. Esta marca no te va a fallar, he comprado varias y siempre genial. La recomiendo totalmente, aunque veáis otras un poquito más barata, no lo dudéis.

Pour faire simple voici les points les plus importants selon moi concernant cette carte Micro SD SanDisk : - Idéal pour n'importe quel smartphone ou camera sportive pour "gonfler" sa mémoire, surtout pour nos smartphones qui maintenant film en 4K. Pour mon S7 Edge cette carte est vraiment TOP. - Aucuns soucis de compatibilité rencontré, avec tout mes appareils . - Packaging simple, mais bien protégé. - Pour la vitesse de transfert , cela est du très bon pour ma part (en moyenne 50MB/s en écriture et 70MB/s en lecture) . Au final pour le prix et la capacité ainsi que les performance de cette carte, je la recommande fortement , surtout que SanDisk n'a plus rien à prouver et reste une valeur sur sur ce genre de produit.

works well

I purchased this memory card last year still i am using it in my mobile. Currently the same card is inserted in my device now. Its SanDisk ultra 16gb class 10 memory card. Its data transfer rate is mind-blowing. Helps to store HD movies that i watch on my phone when i travel. SanDisk says 80mbps speed but i am getting maximum 50-53mbps speed til now. I purchased it for 373₹ with free shipping. Merchant delivered it with good packing and before mentioned date. Pros: 10 year's warranty. Awesome data transfer speed. Comes with adaptor no need to buy other card reader. Gets usable memory 14.83gb. Connect instantly when connected to computer using mobile, camera with data cable. Cons: Take little bit time when connected to first time to the computer by inserting it in adaptor for installing driver.

Works great and is straight from Sandisk. Super happy and have replaced all my SD cards with Sandisk Ultra. Way better and worth the investment compared to other brands i have used including kingston.
