What is USB3.1 and USB Type-C?
USB 3.1 is a new standard defined by USB-IF (USB Implementers Forum).
- USB 3.1 Gen1 (SuperSpeed): merely a renaming of USB 3.0 (theoretical bandwidth of up to 5Gbit/s)
- USB 3.1 Gen2 (SuperSpeedPlus): an impact on the transfer speeds (double the theoretical bandwidth of up to 10Gbit/s)
(1) USB Type-C is a new connector type introduced by USB-IF in the USB Type-C Specification 1.0.
(2) The Type-C connector is a reversible plug-and-play connector for USB devices.
(3) USB Type-C can be applied to the host device, the USB device and cables.
- Please refer to the below connector table to check the USB port of your platform.
For further confirmation, please check the specifications of your host device or seek for the technical support from your host device manufacturer.
- Yes, you can upgrade your device to USB3.1 Gen1 / Gen2 by an supported add-on card.
- No, USB 3.1 is the USB specification, whereas Type-C is merely a USB connector type.
- There are three types of connectors that comply with USB 3.1, including Type-A (Standard-A), Type-B (Standard-B / Micro-B) and Type-C. Please refer to the below connector table for more information.
Why is the actual storage capacity of the product slightly less than the volume written on the product specification?
Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, when in fact the correct calculation is 1,024KBs. So, for a 8GB storage device, Windows will calculate it as having a capacity around 7.2GB.
Why can't I transfer a 4GB or larger file to my USB flash drive or memory card?
SOLUTION 1 - Format in exFAT
exFAT file system that allows a single file larger than 4GB to be stored on the device. This file system is also compatible with Mac.
Windows 7 and Mac OS 10.6.6 and higher are compatible with exFAT out of the box. Older operating systems may need a patch installed for exFAT compatibility.
1. Double-click on My Computer.
2. Right-click on the flash drive or memory card, then select Format.
3. In the File System list, click exFAT.
4. Click Start.
5. Click OK to start formatting.
SOLUTION 2 - Format in NTFS
Formatting the device as NTFS will make it unwriteable on a Mac computer. Most Mac computers can read NTFS, but not write.
NTFS is a journaled file system, this creates more read/write activities. Therefore, it MAY decrease life expectancy of your device.
Once the device is formatted as NTFS, you MUST use "Safely Remove Hardware" to remove your device.
1. Plug in the device to the PC.
2. Open The Computer Management Console
a) Windows 8
b) Windows XP, Windows Vista, Windows 7
3. On the Left side select Device Manager
4. On the right side expand Disk Drives
5. Right-click on the flash drive, then select Properties.
6. Click the Policy tab.
7. Select Optimize for performance, then click OK.
1. Double-click My Computer.
2. Right-click on the flash drive, then select Format.
3. In the File system list, click NTFS.
4. Click Start.
5. Click OK to start formatting.
