FAQ

The actual usable storage capacity may be less than the labeled capacity due to differences in measurement standards used by storage manufacturers and operating systems. Manufacturers calculate capacity using decimal units (1GB = 1,000MB), while operating systems display storage using binary units (1GiB = 1,024MiB). In addition, a portion of the storage space is used for formatting and system functions.

Our USB flash drives are available in a wide range of capacities from 128MB to 1TB depending on the model and performance class, so you can choose the size that best fits your daily storage, work files, or media backups.

KOOTION offers USB-C flash drives with aluminum alloy, zinc alloy, and high-quality plastic housings, providing a balance of durability, heat dissipation, and lightweight portability.

No. USB-C flash drives are bus-powered and draw power directly from the connected device, requiring no additional power supply.

Storage manufacturers calculate capacity using decimal units (1GB = 1,000MB), while operating systems display capacity using binary units (1GiB = 1,024MiB). Additionally, a small portion of the storage space is reserved for formatting and system functions, resulting in slightly less usable capacity.

A microSD card is designed to expand storage capacity across a wide range of digital devices. It is commonly used in smartphones, tablets, action cameras, drones, dash cams, and handheld gaming devices.

The difference lies in storage capacity and file system support. microSDHC cards support capacities up to 32GB, while microSDXC cards support larger capacities, ranging from 64GB up to 2TB, making them better suited for high-resolution video, continuous recording, and large data storage.

U3 and V30 are speed class ratings that indicate a minimum sustained write speed of 30MB/s. These ratings are especially important for tasks such as 4K video recording, where consistent write speed is required to prevent dropped frames or recording interruptions.

The A1 (Application Performance Class 1) rating indicates that the card is optimized for running applications. It ensures faster app launch times and smoother operation when used in smartphones, tablets, or other app-based devices.

Yes. For reliable 4K video recording, microSD cards with U3 or V30 ratings are strongly recommended, as they provide the sustained write performance required for high-resolution video capture.

Yes. microSD cards are widely used in action cameras and drones due to their compact size, fast speeds, and compatibility with high-frame-rate video recording and continuous shooting.

KOOTION microSD cards are engineered for durability and are designed to withstand water exposure, shock, vibration, and extreme temperature conditions, making them suitable for outdoor and professional use.

Under normal usage, performance remains stable. KOOTION high-quality microSD cards with reliable flash memory and controllers are designed to maintain consistent speed and durability over extended periods.

Yes. External SSDs work with most smartphones, tablets, laptops, and desktops, depending on the interface and operating system.

Yes. High-speed external SSDs are designed to handle demanding tasks such as photo editing, video editing, and content creation. With sufficient transfer speeds, users can edit files directly on the drive without copying them to internal storage, improving workflow efficiency.

Yes. To achieve maximum transfer speeds, it is essential to use a high-quality and compatible cable that supports the same USB standard as the SSD. Using a lower-rated cable may result in reduced performance.

Manufacturers calculate capacity using decimal units (1GB = 1,000MB), while operating systems display storage using binary units (1GiB = 1,024MiB). This difference, along with file system formatting, results in a lower displayed usable capacity.

Yes. Our external SSDs are plug-and-play, requiring no additional drivers on supported systems such as Windows, macOS, Android, and Linux. They are ready for immediate use upon connection.

No. External SSDs are typically bus-powered, drawing power directly from the USB connection, eliminating the need for an external power adapter.

Yes. With no moving parts, external SSDs are shock-resistant and more reliable than traditional hard drives when traveling.

SATA SSDs use the SATA interface, with maximum real-world speeds of approximately 500MB/s. NVMe SSDs, on the other hand, utilize PCIe lanes and the NVMe protocol, enabling much higher bandwidth and substantially faster read and write speeds. NVMe SSDs are ideal for performance-critical applications such as gaming, video editing, and data-intensive workloads.

The most common internal SSD form factors include 2.5-inch SATA SSDs, which are widely compatible with laptops and desktops, and M.2 SSDs (such as M.2 2280), which connect directly to the motherboard and support both SATA and NVMe interfaces depending on the model.

Yes. Upgrading from an HDD to an SSD can dramatically reduce system boot times, application loading times, and file transfer delays, resulting in a noticeably faster and more responsive computing experience.

You can verify NVMe support by reviewing your motherboard’s specifications on the manufacturer’s official website or in the user manual. Look for M.2 slots with PCIe and NVMe support. Some older systems may have M.2 slots that support SATA only.

PCIe 4.0 provides approximately double the bandwidth of PCIe 3.0. When supported by the motherboard and processor, PCIe 4.0 SSDs can achieve significantly higher read and write speeds, making them suitable for advanced gaming, professional content creation, and high-performance computing tasks.

TLC (Triple-Level Cell) NAND flash stores three bits per memory cell, offering a strong balance between performance, capacity, durability, and cost. It is widely used in consumer and professional SSDs due to its reliability and efficient price-to-performance ratio.

While SATA SSDs generally do not require additional cooling, high-speed NVMe SSDs may benefit from heatsinks or integrated thermal solutions. Proper heat management helps maintain stable performance, prevents thermal throttling, and extends the lifespan of the drive during sustained workloads.

Yes. SSDs significantly improve game loading times, reduce in-game stuttering, and enhance workflow efficiency for video editing, 3D rendering, and other creative applications that rely on fast data access.
