OK for the price (problems with NTFS) (2nd batch slower, so devalued)

IMPORTANT:
The biggest shortcoming: When delivered the drive is formatted in FAT32, thus utilizing the potential speed when writing is not enough. In addition to thus imposes an unnecessary limit on the file size to 4GB.
So: First exFAT format.
Question: Why not NTFS? - In NTFS unexplained speed drops, I still was able to observe with any other USB storage device or internal hard drive here. Even formatting (also quick format) advised as an ordeal.

Pro Contra:
+ Much memory for "little" money

o acceptable for the price transfer rates in the 1 st batch
- In the 2nd batch write rates only on USB2 level

- File system as delivered unnecessarily slow
- In NTFS sporadic drops in velocity (NTFS formatting takes "forever")
Difficult to achieve sluggish sliding mechanism, "extended" Endraste -
- Still not strong enough to withstand the stiff Sliding cam latching USB port
- Cheap material appearance
- Fit USB port not OK: very stiff to insert and remove (all other USB connections with other USB devices and Cables fit without problems)
