Overview
A rugged metal casing wraps the NAND memory in this thumb drive, which uses a standard Type A plug. Samsung rates the casing as dust proof, temperature proof and water resistant, which suits a keychain or a laptop bag.
Carrying files between a laptop, a tablet and a TV is the simple job here, and the metal body copes with pockets and bags. The limitation is the connector: the listing shows only Type A, so newer devices with USB-C ports need an adapter.
Who it's for
A keychain drive for carrying documents and photo folders suits this kind of casing. Owners who need a Type C plug on the drive, or want much more space, should shop elsewhere.
Pros and cons
- Metal casing resists knocks
- Water and dust resistance
- Fast read speed for its class
- Compatible with TVs and tablets
- Type A connector only
- Write speed is half the read speed
- Tiny body is easy to lose
- No cap or lanyard listed
Performance notes
Read speed is higher than write speed because flash memory programs cells more slowly than it reads them. Large video copies run at the write rate, so a long transfer takes noticeably longer than opening the same file. Speeds depend on plugging into a port of the rated generation; slower ports lower both numbers.
