Good one.

The USB drive is small, has two sided male ports (USB A and USB C) which can slide out of the USB casing. Note: USB A is the general keyboard and mouse USB connector and USB C is apple's charging cable connector which now a days is common in most smartphones. The USB drive becomes hot when being used on USB C port for large transfers and is common. It can be plugged into mobile phones which has C type charging cable. The actual storage that you would get would be 114 GB. It would never be 128 GB as the rest is occupied by the drivers to run the USB drive. The drive supports exFAT (default) and NTFS file systems only. The actual transfer rate depends on a lot of factors like the type and generation of USB connector, the type of storage, processor, motherboard, etc. Transfer rates are good. I've tested it and shared the results below. The transfer rates may have gone down to 20 MBps in case of 50 MBps for HDD. The 600 MBps mark for HDD (3) went down to 80 MBps and remained constant. 1. USB A 2.0 (copying to and from SATA HDD) - maximum transfer rate up to 16 MBps 2. USB A 2.0 (Coping to and from NVME or SATA SSD) - maximum transfer rate up to 200 MBps 3. USB A 3.0 (Copying to and from SATA HDD) - maximum transfer rate up to 600 MBps 20 MBps 4. USB A 3.0 (Copying to and from NVME SSD) - maximum transfer rate up to 600 MBps and 50 MBps respectively 5. USB C 3.2 (Copying to and from SATA HDD) - maximum transfer rate up to 100 MBps and 50 MBbps respectively 6. USB C 3.2 (Copying to and from NVME SSD) - maximum transfer rate up to 130 MBps and 50 MBps respectively
