To archive data for long periods of time I recommended the SanDisk Extreme Go retractable USB Drive.

I chose this model because of:

The high transfer speed which will allow for some of the fastest reads and writes currently available in USB Drives.  This will greatly reduce the time spent loading large amounts of data.
It is designed for long life under use so if your archive must be accessed many times through the years it will survive longer than standard USB drives.

The retractable design will keep the USB connector inside the case reducing the risk of damage due to environmental exposure over time.

There is one caveat when using USB Drives or any flash based storage for long term archival.  In the world of storage, flash is still a fairly young technology so we don’t have definitive knowledge regarding its durability over many decades.  While flash chips are nonvolatile, meaning they continue to store information even when there is no power source, that data is retained in the form of an electron charge.  Over long periods of time the charge could be lost.

Plugging the drive into a powered device occasionally should mitigate loss of charge by recharging the cells, but there are some indications that without being plugged in, USB drives may have an upper limit of ~10 years for retaining charge.

Here’s a decent article about different options for archiving data. Note the USB drive pictured in the article is the one I have recommended.

I hope this information was helpful. Please contact me again if you have further questions.
