How can I customize my MicroSD Cards 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 Cards capacity 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

TF Card Explained: Identity, Specs, and Evolution
What is a TF Card?
A TF card (short for TransFlash card) is a type of ultra-compact, removable flash memory storage card. Today, it is universally known and standardized as the Micro SD card. “TF” is an older or colloquial name, while “Micro SD” is the modern, official term used in specifications and retail. They refer to the same product.
From TransFlash to Micro SD: Why the Name Changed?
The card was originally launched by SanDisk in 2004 under the name “TransFlash” (TF). Soon after its release, it was adopted by the SD Association, standardized, and officially renamed Micro SD to align with the existing SD card family. The “Micro” denotes its size—it is only about 1/4 the size of a standard SD card.
Physical Size and Capacity Standards
Size: Extremely compact at 11mm x 15mm x 1mm.
Capacity Standards: It comes in evolving capacity formats:
Micro SD: Up to 2GB
Micro SDHC (High Capacity): 2GB–32GB
Micro SDXC (Extended Capacity): 32GB–2TB
Micro SDUC (Ultra Capacity): 2TB–128TB
Popular Capacities: Commonly available in 16GB, 32GB, 64GB, and 128GB.
Practical Usage: Capacity, Speed, and Recommendations
Understanding Speed Classes for Performance
Cards are labeled with speed ratings (e.g., Class 10, UHS-I, A2, V30) that indicate minimum write speeds. This is crucial for smooth video recording, fast app performance, and reliable operation in devices.
Primary Uses and Applications
Initially used to expand storage in older mobile devices, TF/Micro SD cards are now versatile storage solutions for:
Expanding storage in smartphones, tablets, digital cameras and action cameras.
Storing footage in dash cams, drones, and security cameras.
Saving games and media on handheld consoles like the Nintendo Switch or other portable devices.
Use in GPS devices, music players, and various industrial/medical devices.
Key Recommendations for Buyers
For Video Recording/Cameras: Choose a card with 32GB or more capacity and a Speed Class of C10 or above (e.g., V30). This ensures stable recording and prevents card damage or slow performance. Poor-quality cards can harm device functionality.
As a USB Drive? Yes, with a USB card reader, a Micro SD card functions like a USB stick. This is a common method to transfer photos and videos from cameras.
Using Adapters: A Micro SD card can be used in a full-size SD card slot via a passive adapter without issues regarding dust or humidity, as it remains protected inside the host device.
In Short:
If someone says “TF card,” they mean a Micro SD card—a tiny, removable memory card used to store data in a vast array of portable electronics, from cameras and phones to drones and consoles.
