Summary and Conclusion:
Portable storage is a massive market place. With the explosion of file sizes and impatient users that need to move large chunks of data flash drives and portable hard drives have flooded the marketplace. Most drives consist of a cheap plastic casing with a standard no-frills drive packed inside. Performance of many portable hard drives is bottle-necked by an aging USB 2.0 standard. Luckily companies such as Silicon Power and others have realized the need to adopt the latest USB 3.0 standard into the portable drive design. A speedy interface combined with a strong, durable, waterproof exterior is a great mix of new innovation and unique features that may not be totally necessary, but any user that has ever lost files due to a snapped USB flash drive or a dropped portable hard drive will jump at this drive. The performance for a portable hard drive is very good considering the price the Armor A80 retails for online, but it would be nice to see an SSD version with the same rugged features…
Altogether this portable storage solution sports some unique and life-saving features that other device makers just do not offer (or at least not at a consumer price). The Silicon Power Armor A80 would be my first recommendation for anyone needing a portable storage solution that will weather the storm, drops, and falls of day-to-day life.

I bought a80 but i find a problem for it, I couldn’t copy bigger file size such as 6 gigs up on it and shows error message in copy of file.(I have a enough space on it)
The drive is formatted as Fat32. Format it as NTFS and your problems disappear.
