UASP allows data to be transferred from external hard drives and other devices to a computer. When used in conjunction with a USB 3.0 or higher port, this enables fast data transfer.
What UASP offers
UASP allows data to be transferred from SSDs, USB sticks and DVD drives to a computer via USB. The advantage of this is that it works very quickly:
- UASP is a communication protocol that allows mass storage devices to be connected to a PC via USB.
- Suitable mass storage devices include, for example, SSDs or DVD drives with a SCSI or Serial ATA connection.
- With UASP, the data transfer rate is approximately 450 MB/s. This equates to around 3,600 Mbit/s.
- A prerequisite for this is that both the computer and the external storage device have a USB 3.0 port or higher. Only then can this very fast data transfer take place.
- Standard external hard drives or older USB sticks are therefore not suitable for UASP, as such high transfer speeds cannot be achieved with them.
- Furthermore, the software on your computer must, of course, be compatible with this feature. From Windows 8 onwards, this is already supported out of the box. For older operating systems, special drivers must be installed.
- As only a few manufacturers explicitly advertise support for UASP, you should enquire about this with the retailer before making a purchase. Alternatively, after purchase, you can use Device Manager to check whether your device supports UASP.
