ADATA 16GB Premier microSDHC UHS-I / Class 10 Memory Card with SD Adapter, Speed Up to 50MB/s (AUSDH16GUICL10-RA1)

Pros: H2testw 1.4 PASSED! USB3 card reader - 15,270 space tested 11.6 MB/s Write 83.9 MB/s Read A1 Bench - Android 4.4 Kitkat - LG Volt quad core 12.46 MB/s Write 61.59 MB/s Read

Cons: None

Pros: The package looks nice when it's new.

Cons: Technically this is the second unit I am reviewing. This is the replacement I was sent by newegg (which took care of the RMA quickly). This unit looked brand spankin' new. I formatted the card as soon as I popped it in my phone (Galaxy S2). All seemed well. I saved a ton of pictures just fine....or at least I thought I did. The next day I tried to view what I had saved and there was nothing there anymore. Only the little "corrupted" pic. I would normally return it for a replacement...but 2 in a row is too many. Eventually I'll end up spending more on shipping all these units back and end up owning and have nothing to show for it. I will not be purchasing anymore ADATA cards.

Overall Review: I think the 'Cons' sums it up pretty well. I'd suggest others pay an extra buck or two and not have to spend that extra money on shipping these defective units back. Thanks for your time.

Pros: Small. Nice Gray and black color scheme. Looks good with a black phone or camera and a tuxedo

Cons: (edit: I purchased a 3 pack of these. All three are now dead. Less than a year. Used in three different devices (phones) Adata didn't respond to my support request.) (original review): It just stopped working one day. Unfortunately that day was in paris after a day of photo taking. It won't format or anything. I'm trying to get a warranty from Adata but it requires a serial number, which the card does not have.

Pros: Card was corrupted when my better half pulled it out of a trail cam while it was writing. ADATA replaced it promptly, with no questions asked.

Cons: None.

Overall Review: I have several of their cards and flash drives and all the others have worked fine.

Pros: Works perfectly in an older Sandisk Sansa Clip+ music player, which is notoriously fussy about which larger cards it will accept. As such, it meets my needs exactly.

Cons: No meaningful downsides found.

Pros: ADATA Premier 16GB microSDHC/SDXC UHS-I U1 Memory Card with One Adapter (AUSDH16GUICL10-RA1) Using in four Raspberry PI 3 computers. No problems. Working flawlessly. Using in San Disk Clip Zip - loaded with music, audio books, podcasts. Works well. No problems. Bought on Shell Shocker - 3.66/chip - nice!

Cons: None so far.

Overall Review: These ADATA 16Gb memory cards seem to be a quality product. Bought six - all currently working.

Pros: Retail packaging, helps to keep product from damage in transit. Great read speeds (more in Other Thoughts). Great price per GB for this type of item. Much better than the Class 6 speed cards of this type on reads.

Cons: Write speeds could be better, depending on use.

Overall Review: As mentioned on Pros, while the write speeds aren't much faster than the card it replaced, the read speeds are 3x faster than a Class 6 card that I recently purchased, not paying attention to the details, just the price. Though all wasn't lost on that one, took the ADATA adapter and placed the Class 6 brand in my digital camera & use this one with a USB 3.0 card reader. Great replacements for Flash drives when on promo, and in my case, used to create a portable bootable Linux Mint OS. That allows me to boot & run my OS from most any computer that doesn't have Secure Boot, which is what I wanted it for. That allows me to boot and use my portable OS on any computer w/out leaving a trace behind. Of course they'll wear faster with this type of use, but what's $7 on promo for these cards? If it lasts through the warranty & fails, no big deal, something faster will be the standard. The only thing I see that needs improvement on these cards are write speeds. 16MB/sec writes are about tops, while reads are a decent 40MB/sec. Then again, I knew I wasn't purchasing a SSD when ordered, and for the money (on promo), it's a good card.

Pros: Fast card

Cons: Slowest shipping ever from DHL

Overall Review: Love the MicroSD card and newegg. I hate it when DHL is the shipper DHL shipping is awful and VERY VERY slow.
