If you have been around APH Networks for a while, you will notice we frequently talk about our history. Why do we like to talk about our history? Is it because, as Spanish-American philosopher George Santayana puts it, "Those who cannot remember the past are condemned to repeat it"?

I bought 2 of these at Ktech aka IMPC. One was much slower than advertised. Writing speed: 35.7 MByte/s Reading speed: 38.9 MByte/s 57.8GB in 1GB blocks The other one 'disappeared' from the USB port after 1.5GB of data written. Reproducible. Worked in a pure USB 2.0 port though. KTech aka IMPC offered me a refund after they had them tested at their supplier.

I bought two of these at KTech aka IMPC. One was much slower than advertised: with 57.7x 1GB test data (optimal) Writing speed: 35.7 MByte/s Reading speed: 38.9 MByte/s The other one unplugs after the first 1.5GB of data written reproducible. It works in a pure USB 2.0 port though. KTech aka IMPC had them tested at their supplier and offered an refund for the pure item costs afterwards. The shipping costs back and forth were my entry costs in the lottery for a product that works as advertised. A bit slow but a friendly Service indeed.

Same as another Adata USB model, it does not work with my Lenovo and Asus front USB slots. Either can't detect or system crash. But it works fine on rear direct USB slots.

Value; Speed; Nice looking

Doesn't work with some PCs

I'm getting great speeds from this flash drive at around this is the fasted flash drive I've ever owned. I'm quite happy with the price, read and write speeds. Read speeds are around 185mb/s – 190mb/s write speeds are around 40mb/s – 50mb/s. The drive is quite reliable for storing data.

This USB flash drive does not work and appearing as an empty disk drive, also the Disk Management reports "No Media" with 0 bytes size; this mostly happens due to poor controller or cheap memory. Not that I used it extensively, max 40-50 times in last 3 years.
