He is notable for incorporating the world's first single chip USB flash controller. Pua founded Phison Electronics based in Taiwan with four other partners and is believed to have produced the world's first USB flash drive with system-on-chip technology.

Trek Technology and IBM began selling the first USB flash drives commercially in 2000.

A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case which can be carried in a pocket or on a key chain, for example.

The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected.

Some devices combine the functionality of a portable media player with USB flash storage; they require a battery only when used to play music on the go.

Pua Khein-Seng from Malaysia is considered by many to be the "Father of Pen Drive".

File transfer rates vary considerably among devices; typical fast drives from this generation claim to read at up to 30 MB/s and write at about half that rate, which is about 20 times faster than the theoretical transfer rate achievable by USB 1.1, which is limited to 12 Mbit/s (1.5 MB/s) with accounted overhead.

for example, small writes to random locations are much slower (and cause more wear) than long sequential writes.USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc. USB flash drives are often used for the same purposes for which floppy disks or CDs were once used, i.e., for storage, data back-up and transfer of computer files.They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts.In 2000, Lexar introduced a Compact Flash (CF) card with a USB connection, and a companion card read/writer and USB cable that eliminated the need for a USB hub.By 2003, most USB flash drives had USB 2.0 connectivity, which has 480 Mbit/s as the transfer rate upper bound; after accounting for the protocol overhead that translates to a 35 MB/s effective throughput.USB flash drives use the USB mass storage device class standard, supported natively by modern operating systems such as Windows, Linux, and other Unix-like systems, as well as many BIOS boot ROMs.
