128MB Micro SD Card Bulk
128MB Micro SD card is the cheapest and lowest capacity standard Micro SD card we currently wholesale. It supports both read and write and is ideal for basic storage tasks. Although there are many large capacity Micro SD cards now, the lower cost and stable quality make 128MB Micro SD card still very popular. It is widely used in compact electronic devices such as portable speakers, voice recorders, feature phones, tablets, and MP3 players. Due to its low cost, it is also the best choice for giveaway and accessories.

Verified Speed means that the real read and write performance of our memory cards matches the stated specifications, not just short-term “peak” speeds. By professionally matching controller chips with branded NAND flash, our products avoid sudden speed drops, write interruptions, and performance instability commonly caused by aggressive caching strategies or low-quality components. Every production batch undergoes real-world read and write verification, with a strong focus on sustained performance during continuous writing and repeated read/write cycles.
True Capacity means that the nominal capacity of a memory card accurately reflects its real, usable storage space. It does not mean “zero difference”; due to different calculation methods, the usable space shown on a computer is slightly less than the nominal value, which is normal and within industry standards. Neomory memory cards undergo strict capacity verification tests such as H2 and H5 to ensure stable read and write performance and full data integrity, even during long-term use or when the card is filled close to its maximum capacity.
Stable Reliability means that a memory card can deliver consistent, stable performance during long-term, repeated use. In many applications, stability matters more than extreme speed. We use mature controller solutions combined with branded NAND flash, and carry out basic stability verification and testing on every production batch. This helps minimize the risks of controller faults, inconsistent flash components, and compatibility issues, ensuring reliable performance.
Customization means we offer flexible solutions ranging from basic OEM services to fully customized storage products. We provide complete OEM and ODM services, including logo branding, casing and packaging design, and customized labeling specifications. Neomory also supports deep customization of key storage parameters such as capacity, speed class, controller solutions, flash memory type, and compatibility strategies. In addition, we provide data services such as data preloading and read-only locking based on actual application requirements and device usage scenarios.
