Pack of 100 Micro SD Card 4GB MicroSDHC C6 - Bulk Memory Pack

In this review the focus is on the Cloudisk Pack of 100 Micro SD Card 4GB MicroSDHC C6, a bulk memory option aimed at users who need many low-capacity cards for devices and deployments. The bottom line: this pack is for anyone who needs reliable, inexpensive micro SD cards in volume - schools, rental fleets, makers, or businesses that deploy cameras and sensors. The reviewer found the cards to be straightforward, broadly compatible, and tested for data integrity, making them a pragmatic choice when quantity and known baseline reliability matter.

Key Features

• Wide device compatibility: The cards work in smartphones, tablets, cameras, GoPro and action cameras, laptops, desktop computers, DSLRs, drones and portable consoles, ensuring one card type covers many devices.
• Pack of 100: Supplied as 100 individual micro SD cards with two plastic cases holding 50 each, this reduces procurement time for large projects and keeps cards organized.
• Pre-shipment testing: Each Micro SD card is tested one by one with H2testw for basic integrity, lowering the chance of dead cards on arrival.
• Durability checks: Cards are described as water proof, shock proof, x-ray proof and temperature proof, offering peace of mind for in-field and travel use.
• Regulatory certification: The micro SD cards have obtained FCC, CE and RoHS certificates, which supports electrical safety and compliance in many markets.

Who It's For

This pack is best for buyers who need many small-capacity cards for distributed deployments: educators provisioning tablets, content rentals supplying action cameras, security firms stocking replacement cards for CCTV, or hobbyists and makers who load firmware or media onto multiple devices. The low 4GB capacity is sufficient for firmware, small data logs, or short video clips on many devices.

Users who need high transfer speeds, long-form 4K video storage, or single-card performance for professional photography should look elsewhere for higher-capacity and higher-speed UHS cards. This product is intended as an economical, reliable bulk supply rather than a premium performance card.

Pros & Cons

Pros

• Very cost effective when buying 100 cards, reducing unit cost for large projects.
• Broad compatibility covers a wide range of devices from smartphones to drones and portable consoles.
• Individual H2testw checks and durability testing lower the risk of arriving with defective cards.
• Regulatory certifications like FCC, CE and RoHS add confidence for institutional purchases.

Cons

• Only 4GB capacity per card limits usefulness for long video recording or large media libraries.
• Speed class and detailed transfer rates are not emphasized, so these cards may not meet high-speed capture needs.
