I purchased this pendrive from Hukut Store for NPR 899, and this is a personal, non-sponsored, honest review based on real usage testing.

⚡ USB 3.2 Performance Analysis
The pendrive supports USB 3.2 Gen 1 interface.
What USB 3.2 Gen 1 Means
USB 3.2 Gen 1 is essentially the rebranded version of USB 3.0 technology.
The theoretical maximum transfer speed is around 5 Gbps, but real-world performance is always lower due to:
Controller processing overhead
File system efficiency
Source device limitation
Thermal throttling
File size variation
🚀 Real Speed Test Results
During testing, the pendrive showed:
Read Speed → Up to ~100 MB/s (manufacturer claim range)
Write Speed → Depends on file type and system workload
Important observation:
Large file transfers maintain relatively stable speed.
Small file transfers may fluctuate due to storage block management.
The performance is considered very good for a 64GB budget USB storage device.
📂 Storage Capacity & Usage
The 64GB storage capacity is suitable for:
Document backup
Media storage
Student data storage
Software installers
Portable file transfer
Actual usable storage may be slightly less than 64GB due to file system formatting and firmware reservation.

No severe overheating issues occurred
This is normal behavior for portable flash storage devices.
