G.Skill 64GB microSDXC UHS-I/U1 Class 10 Memory Card with Adapter (FF-TSDXC64GA-U1)

Pros: -Fast -Lower priced that some of the competition -Lifetime Warranty from a well known brand

Cons: None so far

Overall Review: EDIT: I had to post this a second time due to a typo, hopefully this review doesn't get posted twice. Make sure your device supports exFAT, as thats the format this card comes formatted in. I’m very happy with purchasing this card so far. The microsd card slides in and out of the adapter very easily, unlike some other brands, although I won’t be using the adapter. Below are my rough benchmarks on my desktop. Your results may vary depending on the speed of your computer and usb card reader. My desktop PC is an Intel i5-3570K cpu, using an Asus P8Z77-v motherboard. The USB 3.0 card reader is a Transcend model: TS-RDF5K. *** USB 3.0 (CrystalDiskMark) *** Seq: Read: 68.07 MB/s Write: 20.38 MB/s 512K: Read: 60.22 MB/s Write: 17.40 MB/s 4K: Read: 4.915 MB/s Write: 1.065 MB/s 4K QD32: Read: 5.299 MB/s Write: 1.188 MB/s *** USB 2.0 (CrystalDiskMark) *** Seq: Read: 35.55 MB/s Write: 19.81 MB/s 512K: Read: 34.48 MB/s Write: 17.63 MB/s 4K: Read: 4.196 MB/s Write: 1.141 MB/s 4K QD32: Read: 4.753 MB/s Write: 1.187 MB/s I am using this in my Samsung Galaxy Note 8.0 tablet, and kept the exFAT format it comes formatted in, for now anyways. I get close to the same benchmarks using the “Sd Card Tester” app when the card is inserted into the tablet itself.

Pros: Lifetime warranty Decent performance as shown below: Crystal Disk Mark • Sequential: Read = 17.12 MB/s, Write = 9.093 MB/s • 512k: Read = 16.72 MB/s, Write = 6.401 MB/s • 4k: Read = 3.434 MB/s, Write = 1.112 MB/s • 4k QD32: Read = 4.348 MB/s, Write = 1.424 MB/s ATTO • Read: 16.47 MB/s • Write: 5.97 MB/s

Cons: None

Overall Review: Great SD card for the price *All tests were conducted three times to ensure accuracy and repeatability of results.

Pros: Fast Cheap Lifetime Warranty

Cons: None

Overall Review: 64GB for around $20? YES PLEASE! Bought this For My Nikon D3200 as an upgrade from a old 16GB. This Card has no issues recording Video at the highest setting (1080p @ 30fps). Burst shooting as fast as I press the button. What more do you want?

Pros: Lets face it, we are need more space. I needed a new SD card for a new tablet and this fits nicely. Great value, easy shipping. I like the No-Frills option of buying one without the adapter, we all have an adapter by now. I remembered to get the right speed card, I did not want an antique.

Cons: I can't find one

Overall Review: 32GB is a great deal of space for a phone or a tablet.

Pros: Its a lot of space. No issues. Used it in my ContourHD1080p which it says the largest is 16 Gb. Only problem is the memory light stays red. No a big deal

Cons: Cost

Overall Review: Amazing how 8 years ago a 1 Gb SD card was $100

Pros: Fast, cheap, and high capacity. 964 picture capacity on Nikon D610 saving RAW + Normal quality JPEG (1:8 compression). 5.4K (5400-5499) picture capacity on Nikon D610 saving only Normal quality JPEG (1:8 compression).

Cons: Both of the cards I purchased appear to have been previously used. There is sticker on the packaging to hold it shut, but it is easy to peal off without damage, so there is no way to know if what you purchased has been used. In my case, it was quite obvious, however, because both had data on them! The first had a strange version of CrystalDiskMark (folder called "CrystalDiskMark00D8E764"), and reported 4gb of 59gb used. The second had no files visible in Windows, but reported 3gb of 59gb used. When mounted on Windows, both reported that they had been dismounted incorrectly and should be repaired. After snooping around to look for where the used space was, I formatted both. The first formatted without issue, while the second reported an error formatting the first time, but succeeded on the second attempt. Both had to be reformatted in the camera, and neither had a problem. I will be using these in "Backup" mode on my camera for a while to make sure they function correctly.

Overall Review: Using a UtechSmart USB 3.0 reader (Newegg part number 9SIA2690RG7534), connected to a USB 3.0 port, I tested both cards: The first:: ----------------------------------------------------------------------- CrystalDiskMark 3.0.2 x64 (C) 2007-2013 hiyohiyo ----------------------------------------------------------------------- * MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s] Sequential Read : 59.359 MB/s Sequential Write : 32.135 MB/s Random Read 512KB : 55.243 MB/s Random Write 512KB : 4.704 MB/s Random Read 4KB (QD=1) : 4.994 MB/s [ 1219.1 IOPS] Random Write 4KB (QD=1) : 0.880 MB/s [ 214.9 IOPS] Random Read 4KB (QD=32) : 7.177 MB/s [ 1752.1 IOPS] Random Write 4KB (QD=32) : 1.184 MB/s [ 289.1 IOPS] Test : 100 MB [E: 5.9% (3.5/58.9 GB)] (x9) Date : 2013/10/26 8:40:52 OS : Windows 7 Professional SP1 [6.1 Build 7601] (x64) and the second (same settings as above): Sequential Read : 55.058 MB/s Sequential Write : 34.318 MB/s Random Read 512KB : 51.426 MB/s Random Write 512KB : 4.628 MB/s Random Read 4KB (QD=1) : 4.814 MB/s [ 1175.3 IOPS] Random Write 4KB (QD=1) : 0.828 MB/s [ 202.2 IOPS] Random Read 4KB (QD=32) : 6.964 MB/s [ 1700.3 IOPS] Random Write 4KB (QD=32) : 1.150 MB/s [ 280.8 IOPS]

Pros: - Good read/write speeds - Good price

Cons: None.

Overall Review: I have purchased RAM from G.Skill plenty of times in the past and couldn't pass up on this microSD card at the price Newegg was offering it. I popped this little guy into my wife's Galaxy S 5 Active and it is running great. Thanks Newegg.

Pros: Spacious and speedy class 10 micro sdhc. Comes with a SD adapter for easy use in card readers. Price is excellent and I've never had an issue with any G.Skill memory products

Cons: none

Overall Review: Using in my Galaxy S3 phone for expanded storage, backups, firmware builds.
