How can I customize my speed and capacity?
Customers select the best choice for them based on the situation they need.
- Class Low Speed – C4, C6 ( Up to 12M/S read, 4M/S -6M/S Write)
- Class Medium Speed – C10 (Up to 18M/S read, 10M/S write)
- High Speed Class – C10 U3 (60M/S – 90M/S read, 20M/S – 45M/S Wite)
So there would be like:
128GB C4= 128MB Class 4 (Read Speed Up to 12MB/s, Write Speed Up to 4MB/s)
4GB C6 = 4GB Class 6 ( Read Speed Up to 12MB/s, Write Speed Up to 6MB/s)
8GB C10= 8GB Class 10 ( Read Speed Up to 18MB/s, Write Speed Up to 10MB/s)
64GB C10 U3 = 32GB Class 10 UHS-3 ( Read Speed Up to 75MB/s, Write Speed Up to 30MB/s)
256GB C10 U3=256GB Class 10 UHS-3 ( Read Speed Up to 90MB/s, Write Speed Up to 45MB/s)
Capacity is the storage space. The more GB for the capacity, the more videos,photos or songs will be stored.
A MP3 song with 44K/320kbps would be like 2.4M.
8GB ≈ 27,000 Songs;
16GB ≈ 106,000 Songs;
32GB ≈ 426,000 Songs;
128GB ≈ 6,826,000 Songs.
It's fake when I found my TF Card capacity is less?
We do not manufacture or sell any fake ones. It would be less for the storage capacity, it is true.
TF Card 32G = 32* 1000 * 1000 * 1000 = 32000000000 bytes.
And, 1024bytes = 1KB, 1024KB = 1 MB, 1024MB = 1GB
so 32GB MicroSD card storage would be 32000000000 / 1024 /1024 / 1024 =29.8GB.
The system files inside the MicroSD card will also cost space.
Our TF Card Storage Capcity are as below:
16GB – approximately 14GB-15GB
32GB – approximately 28GB-30GB
64GB – approximately 58GB-60GB
128GB – approximately 115GB-119GB
256GB – approximately 230GB-238GB

Some Knowledge about Micro SD TF Cards for your reference:
- What is TF card?
TF card is TransFlash. It is also called Micro SD. It came to the market in year 2004. - Why is it a Micro SD?
It is compact. It is only 1/4 size of a normal SD card. So it is called Micro SD. - What is the popular capacity for TF / Micro SD?
The TF Card capacities are popular as 16GB 32GB 64GB and 128GB. - What is the main usage of TF?
It was used in cell phones for storage years ago to store data, photos, videos and more. Now it is popular in games, cameras, videos and data storage. Because smart phones have a larger capacity than they were years ago. - What do you recommend for video recording or cameras?
TF 32G or more with TF Speed C10 or above. The price is very low and a higher capacity will help to store more. TF Card Speed C10 + will ensure the writing speed from cameras or video records. Poor speed will cause damage to the TF cards or make the Micro SD cards work slowly. Poor speed TF card will also do bad to the cameras. - MicroSD cards can store data like a USB memory stick?
Sure, it can but is not the best way. You need to get a USB card reader and put the TF card in side. Thus, you can use the TF card + Micro SD card reader = a full USB. Many of the camera photos or videos are downloaded in this way. But this is not the best way for data storage. Because the USB memories will have a better workmanship to avoid dust, humidity and drop. And, the same level TF card + good card reader will cost more than a USB memory stick. - Can I use Micro SD and TF Card adapter instead of SD, SDHC or XDSC?
Sure, no problem with that. No worry about the dust, humidity or other! It is in the cameras or machines and there should be protected.
