I got following results.
16GB card
Code: Select all
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 3.68 MByte/s
Reading speed: 4.29 MByte/s
H2testw v1.4
4GB pen drive
Code: Select all
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 2.48 MByte/s
Reading speed: 9.94 MByte/s
H2testw v1.4
In your case, it seems the card is having a faulty flash chip?
Cheep products sometimes introduce issues that cost more than double the most expensive one to sort out. Especially when it comes to me, it doesn't matter I loose my mobile phone but not my Pen drive
.
One other thing... Recently I found a good online computer accessory shop in Sri Lanka. You can order online and they deliver it to your doorstep. I used to buy products from their shop in Unity Plaza called Barclays and they are normally better. Check it out.

seem to be slow
Second generation
Modern flash drives have USB 2.0 connectivity. However, they do not currently use the full 480 Mbit/s (60MB/s) which the USB 2.0 Hi-Speed specification supports because of technical limitations inherent in NAND flash. The fastest drives currently available use a dual channel controller, although they still fall considerably short of the transfer rate possible from a current generation hard disk, or the maximum high speed USB throughput.
File transfer speeds vary considerably and should be checked before purchase. Speeds may be given in Mbyte per second, Mbit per second or optical drive multipliers such as "180X" (180 times 150 KiB per second). Typical fast drives claim to read at up to 30 megabytes/s (MB/s) and write at about half that speed. This is about 20 times faster than older "USB full speed" devices which are limited to a maximum speed of 12 Mbit/s (1.5 MB/s).
can you see how they make money by not providing the full speed
USB 2.0 can 480 Mbit/s (60MB/s) but, why its only writing at 3.63 MByte/s, i think they knowingly limit the transfare rate so they can milk more money by increase of speed every year, you know every year they upgrade the speed, just like hard drive storage
