Silicon Power 128GB up to 75 MB/s MicroSDXC UHS-1 Class10, Elite Flash Memory Card with Adaptor

Pros: Great Quality, Fast, Great Product information

Cons: None

Overall Review: I know some have claimed to get poor performance from their card. Keep in mind you have to be using USB 3.0 in order to get the advertised speeds and have a Hard Drive in the computer capable of the transfer speeds as well. If you are formatting the card and not getting anywhere near the right size. Make sure you are using updated hardware to read the card. If you have an old computer with an old card reader, it isn't capable of reading large SD cards. Format the card in the device you intend to use it in.

Pros: Large capacity for low price. Sequential reads are very fast.

Cons: Sequential writes are pretty slow, between 20-30MB/s depending on method of transfer. Even if you're working with mostly large files, it can take well over an hour to fill.

Overall Review: This would be a great option if you're looking to simply fill a phone's micro sd card slot with your music collection. As long as your collection isn't over 128GB... write once (about two hours) and then you're set! Read speeds are very fast. The card is exFAT formatted by default, like most 64GB+ cards. Use a free tool like GUIFormat for a high-capacity FAT32 format to ensure compatibility in an Android device. This will however restrict your filesizes to 4GB each, or less.

Pros: I was able to consistently get 65Mbs plus on this. I used a read/write tool to measure performance and it lived up to the speeds advertised. The packaging was compact and sustainable. I was able to get the same performance from the SD card as a USB adapter. I like the color of the card and it makes it stand out from others. I am primarily using this card as extra storage in my Galaxy phone but I have used it in my camera and it works well there too.

Cons: I have had no problems with this and do not have any enhancement suggestions.

Overall Review: I have been happy with the customer service, shipping speed and product quality so far. I would recommend any item from them based on my experiences.

Pros: Read speed is about 72mb/s Write speed up to 25 mb/s - Excellent price point - Very large capacity - Has a lock button on the left of the SD card adapter, when locked you cannot delete images or any data - Solid construction, feels like quality product

Cons: Not a lot of people know about Silicon Power when compared to other famous brands

Overall Review: Great memory card, cheaper than micro sd cards of the same storage, and much faster read/write speeds! When it comes to micro SD cards, SP offers good deals.

Pros: High capacity High speeds Works great in cellphones

Cons: Nothing I can find yet

Overall Review: Card came in quickly and works like a charm. Total usable storage is 122gb and read and write speeds are as advertised. I've tried many low priced cards and this one worked flawlessly. I highly recommend it, especially for the price.

Pros: Fast read speed, easily top 85-90 MB/s Write speed are in the the avg 18-22 MB/s

Cons: 20 MB/s write speed could be bottle neck if you're shooting 4k at high bit rate

Overall Review: This version when compare to the Samsung, Sandisk, PNY and other major brands, has very good read speed, easily top 85-90 MB/s. The write speed aren't too shabby either and in the avg 15-18 MB/s. This is plenty for most camera to write video files and using it for my Sony RX100, I'm able to record at high bitrate with no problem. You can check my pictures for the bench mark and also everyday usage speed. The major brands are usually costing a little bit more with similar or slower READ speed. I did notice some of the sandisk and Samsung option offer much faster WRITE speed, but at a higher cost. Keep in mind if this is the Elite version which has a slower Write speed, so if you want the top tier, you need to get the Superior version (which currently I didn't see a refresh this year for 128 GB capacity).

Pros: Fast delivery

Cons: Bad Card. Immediately corrupt both picture and video files upon testing.

Overall Review: Phone recognised card and available storage. Returned for refund. Gave this card a try, due to low sale price, and this happened to be my first Silicon Power card but it was bad. I'll stick with Samsung and SanDisk in the future.

Pros: Cheap

Cons: Not as fast as advertised. On my computers I get 9.3MB/s sustained writes and 15MB/s reads. It could be that in short burst mode or with optimized block size you will do better, but in reality it does not really matter. Most likely this is what you'll get.

Overall Review: Looking at the ad I was hoping for better then average performance. It turned out to be just below class 10.
