Blazing-Fast Transfers, Limitless Efficiency

Blazing-Fast Transfers, Limitless Efficiency

The SD820 supports the USB 3.2 Gen2 x2 specification, delivering transfer speeds approximately 20 times faster than conventional external hard drives. With read/write speeds of up to 2000MB/s and massive storage capacities of up to 4000GB, you can directly access and edit large files on the SSD. This offers a seamless and uninterrupted high-efficiency experience for content creators and professional photographers alike.

 

*To achieve optimal performance, the host device must support USB 3.2 Gen 2 and the UASP driver. Actual performance may vary depending on the host device's hardware and software configuration.

26.5g Featherweight Design, Effortless Portability

Who says toughness must be heavy? The SD820 features a featherweight design, weighing only 26.5 grams. Its extremely compact body can be easily stored in a pocket or bag, truly realizing the concept of "storage that follows you like a shadow," so light you'll barely notice its presence.

IP68 Water and Dust Proof for All-Weather Protection

IP68 Water and Dust Proof for All-Weather Protection

From outdoor adventures to unexpected daily situations, the SD820 is built to handle it all. It has passed rigorous IP68 waterproof and dustproof standard tests*, meaning it can completely prevent dust intrusion and survive immersion in water over 1 meter deep for 60 minutes. The user-friendly one-piece waterproof plug seals tightly with a simple click, providing your precious data with leak-proof protection.

 

*The device is only waterproof and dustproof when the USB port cover is fully sealed. Please keep the cover tightly closed when not in use to ensure optimal protection.

Military-Grade Drop Resistance for Hardcore Protection

The SD820 utilizes an innovative dual-material injection molding technique. A TPE soft elastic material is integrally formed with the rigid body, providing excellent impact absorption. The device meets the MIL-STD-810G 516.6 standard*, meaning it can withstand accidental drops from a height of 1.22 meters, ensuring your data remains safe and secure.

 

*The military-grade standard is tested under specific conditions from a height of 1.22 meters. Under normal circumstances, the device should function properly, but please avoid intentionally dropping or damaging the product.

Inheriting a Classic, Powerfully Evolved

Inheriting a Classic, Powerfully Evolved

The design language of the SD820 comes from ADATA's best-selling classic, the HD710 Pro. While inheriting its renowned toughness, the SD820 reduces the size to just one-ninth and implants the top-tier speed of an SSD. This not only brings a familiar sense of trust but also offers an unparalleled tough experience in a sleek and compact new form.

Plug-and-Play with iPhone and Other Type-C Devices

The SD820 features an integrated USB Type-C connector. It's plug-and-play, allowing for direct connection to the latest iPhones, Android smartphones, and tablets for easy data storage, backup, and file management.

  • A:

    New external SSDs  need to be formatted in order for the system to read and write data. The NTFS file system is recommended for Windows system. However, the EXFAT file system is recommended for SE880 external SSD.

    ‎
  • A: Make sure the external SSD is securely connected to a USB port. Detection failure may be related to a faulty USB port. If possible, try connecting the external SSD to another USB port. If detection issues persist, please contact ADATA customer service.‎
  • A: 1. Connect the drive to your Windows PC
    2. Open the Disk Management tool. You can do that by typing "disk format" or "disk management" in Windows search or going to Control Panel > Administrative Tools > Create and format hard disk partitions
    3. Right-click on the external drive partition or the unallocated space you want to format and choose New Simple Volume
    4. Follow instructions to choose a volume size
    5. Assign a drive letter
    6. Choose the file system in the Format Partition screen
    7. Give the volume a new name
    8. Click Next
    9. Click Finish
    10. Formatting complete‎
  • A: If the external SSD loses power or is unplugged in an unsecure manner, Windows may prevent files from being copied to it. This is a Windows protective measure associated with the file system and does not mean the external SSD has a technical issue. You can try resolving this using the following steps:
    - Click the “Scan and Fix” notification that appears when you connect the external SSD to your PC
    - If you closed the notification, right-click on the external SSD icon in the system tray (notification area) and use the “Run CHKDSK” command
    - If the external SSD icon isn’t displayed in the system tray, open Explorer and select the external SSD, then right-click, Properties, Tools, Check‎
  • A: We recommend that you use the Safely Remove Device function before disconnecting the cable between the external SSD and your Android device. Failing to do this may cause copied files to become corrupted and unreadable.‎
  • A: Most new TVs support photo, music, and video playback from external storage via USB. However, not all TVs support this function and file system compatibility may vary. When connecting the external SSD to a TV, please check the following:
    - After connecting the external SSD to the TV USB port, check if the external SSD is recognized in the TV menu
    - If it isn’t recognized, please refer to the TV user manual or contact the manufacturer to check for USB support
    - If it is recognized, check that you can play videos and music and view photos stored on the external SSD without any issues
    - In case content can’t be accessed, verify which file systems are supported by your TV for external storage. The external SSD is formatted using the NTFS file system by default
    - Follow any prompts from your TV operating system relating to the external SSD formatting. Modern TVs will auto-format external storage to a supported file system
    ■Important: formatting will delete all data. Please backup your data before proceeding If the file system is supported but you still can’t access content, verify the file types and extensions supported by the TV.‎
  • A: The actual drive capacity displayed on your device will vary from external SSD physical capacity due to mandatory operating system formatting and partitioning. Typically, operating systems remove 10-20% of drive physical capacity. This means a 250GB external SSD will have around 232GB free once it is fully formatted and detected by a supported operating system‎
  • A: Differences in size shown are mainly due to differences in computer operating systems, the calculation method for an external hard drive capacity, and the Controller IC’s operations result in different ways. Generally, hard disk manufacturers usually calculate capacity based on the decimal system, and computer systems are actually binary. Hard drive manufacturer: 1KB = 1000 Bytes, 1MB = 1000KB, 1GB = 1000MB, 1TB = 1000GB
    Operating system: 1KB = 1024 Bytes, 1MB = 1024KB, 1GB = 1024MB, 1TB = 1024GB
    So for example, a hard disk marked as 500GB capacity is 500GB = 500 x 1,000MB x 1,000KB x 1,000Bytes = 500,000,000,000 Bytes, but in binary the capacity is calculated as 500,000,000,000 Bytes / 1024KB / 1024MB / 1024GB, approximately 465GB.
    Fastest method of calculation: the hard disk capacity x 0.93 = the approximate actual hard disk capacity‎
  • A: UASP stands for USB Attached SCSI Protocol. It combines SCSI commands and USB standards to accelerate data movement and make file transfers more efficient. If your device does not support UASP, you may update it from the device manufacturer website, as UASP functionality can be added via firmware or operating system update.‎
  • A:

    Backup ToGo does not support an encryption function. Use of built-in Windows encryption software BitLocker is recommended (click here to enable BitLocker encryption mechanism on Windows 10 devices).
