Wholesale High Quality Micro SD Cards in Bulk

Storage capacity is a key factor to consider when purchasing Micro SD memory cards in bulk. Depending on your storage requirements, you can quickly choose from the following Micro SD card types before placing your order:

• Micro SD Cards: Up to 2GB, typically using FAT12, FAT16, or FAT16B file systems. Ideal for older devices or applications with low storage needs.
• Micro SDHC Cards: 2GB to 32GB, using the FAT32 file system. Ideal for general use.
• Micro SDXC Cards: 32GB to 2TB, using the exFAT file system. Ideal for large video files and continuous recording.
• Micro SDUC Cards: Above 2TB, supporting capacities up to 128TB. SDUC cards are not yet available in the consumer market.

Micro SD cards (also known as TF cards) are smaller versions of SD cards with the same functionality. Their compact size makes them ideal for small devices such as music players, GoPros, and mobile phones. Neomory wholesales Micro SD cards with capacities ranging from 1MB to 1TB, and also offers memory card accessories such as Micro SD card adapters.

The C Speed class is a basic specification of a Micro SD card and is indicated by the “C” symbol on the card.

• Class 2 (C2): 2MB/s minimum write speed.
• Class 4 (C4): 4MB/s minimum write speed.
• Class 6 (C6): 6MB/s minimum write speed.
• Class 10 (C10): 10MB/s minimum write speed.

The C Speed class defines the minimum write performance of a Micro SD card. Class 2 cards are rarely produced today. Class 4 Micro SD cards are suitable for basic storage, while Class 10 provides higher write performance for applications such as Full HD video recording. Additionally, some older devices or systems only support lower speed classes such as Class 4 or Class 6.

UHS (Ultra High Speed) cards deliver enhanced performance. UHS Micro SD cards are labeled with a “U” symbol (U1 or U3), indicating their minimum sustained write speed.

• UHS Speed Class 1 (U1): Minimum write speed of 10MB/s. Ideal for everyday use and Full HD video recording.
• UHS Speed Class 3 (U3): Minimum write speed of 30MB/s. Ideal for 4K video recording and high-speed continuous shooting.

Application Performance Class ensures efficient random read/write performance for running mobile applications, especially when using a Micro SD card as working storage for smartphones or tablets. Unlike the V-class class used mainly for SD cards, the A-class is especially important for Micro SD cards.

• A1: At least 1500 IOPS read, 500 IOPS write, and 10MB/s sustained write speed. Suitable for general apps and basic multitasking.
• A2: At least 4000 IOPS read, 2000 IOPS write, and 10MB/s sustained write speed. Ideal for more demanding apps and smoother multitasking.

The Micro SD card interface refers to the bus technology used by the cardwhich determinesdetermines the maximum data transfer speed.

• High Speed: Up to 25 MB/s.
• UHS-I: Up to 104 MB/s.
• UHS-II: Up to 312 MB/s.
• UHS-III: Up to 624 MB/s.

Micro SD cards with a UHS-I interface are the most widely wholesale Micro SD cards at Neomory. They are widely used in gaming accessories, promotional gifts, and various consumer electronics. Low-capacity Micro SD cards typically use the High Speed interface and are mainly used in legacy devices. UHS-II and UHS-III micro SD cards—featuring an additional row of contacts on the back—deliver higher data transfer performance, they are rarely seen in the market.
