I am using hp v220w since 1 year ago and still I don’t face any problem in pendrive.
I same the write protected issue 4 months ago but I google the problem and I find the solution.
The writing speed is 4 to 5 MBps.
The reading speed is upto 20MBps.
The get heatup as we use it for too long.
It is available in only one color which is silver.
We need not to install any extra drivers to use this pendrive. it’s just plug and play
We also have space to insert thread in to to protect it form miss place.
In the end I recommended to buy this pen drive.
