USB Flash Drives

USB Flash Drives

A USB flash drive is still the fastest way to move a file between two machines that aren't on the same network — a print file to a commercial printer, a presentation to a venue laptop, a backup that goes in a drawer rather than a cloud account. NXP stocks 13 flash drives from 8GB to 256GB, including dual-connector USB-C models and hardware-encrypted drives from Kingston.

What capacity do you need?

Capacity is the easy decision, and most people overbuy. As a rough guide:

• 8–16GB — documents, spreadsheets, PDFs, presentations. Thousands of them.
• 32–64GB — photo libraries, print-ready artwork, video files, software installers.
• 128–256GB — 4K video, large design files, or a working drive you don't want to keep clearing.

If the drive is being handed to a client or a supplier, buy the smaller capacity. If it's a working drive you'll reuse for years, buy the larger one.

USB 3.0 vs USB 2.0 — and what the numbers mean

Almost everything worth buying now is USB 3.0 (also branded USB 3.1 Gen 1 or USB 3.2 Gen 1 — same speed, renamed twice). It's roughly ten times faster than USB 2.0 in practice, which is the difference between waiting seconds and waiting minutes when you copy a few gigabytes.

USB 3.0 drives are backwards compatible: plug one into an older USB 2.0 port and it will work, just at the slower speed. So there's no reason to buy USB 2.0 deliberately.

USB-A, USB-C, or both

Older desktops and most docking stations use the rectangular USB-A port. Newer laptops, tablets and phones use the smaller oval USB-C. If you're buying for a mixed fleet — and almost every NZ office is a mixed fleet — a dual-connector drive with a USB-A end and a USB-C end saves you carrying an adaptor. The Netac US11 and US18 are the dual-type models in this range.

If ports are the constraint rather than the connector, a USB hub is often the cheaper fix.

Encrypted drives, and when you actually need one

If a drive leaves the building with client data, staff records, financial information or anything covered by your privacy obligations, it should be encrypted. Losing an unencrypted USB stick with personal information on it is a notifiable privacy breach under the Privacy Act 2020 — an encrypted drive turns the same incident into a lost piece of plastic.

Hardware encryption is the stronger option: the encryption runs on a chip inside the drive itself, it's enforced by the drive rather than the computer, and it works on any machine without installing software. Kingston's IronKey S1000 and DataTraveler Locker+ G3 are the hardware-encrypted drives in this range. Both lock down after repeated failed password attempts.

Software encryption — BitLocker To Go on Windows, or a VeraCrypt container — is free and adequate for lower-risk use, but depends on the operating system it's plugged into.

Formatting: the bit that catches people out

A drive that works on one machine and not another is nearly always a formatting issue:

• FAT32 — works everywhere, but can't hold a single file over 4GB.
• exFAT — works on Windows and macOS with no file size limit. The right default for a shared drive.
• NTFS — Windows-native, read-only on macOS without extra software.

If you're handing a large video file to someone, format the drive as exFAT first.

Buying in bulk

Conference bags, student handouts, new-starter kits and archive sets usually mean buying the same drive in quantity. NXP has no minimum order quantity, orders placed by 3pm dispatch the same day from the nearest branch, and freight is free on orders over $50. Buy one drive or fifty.

Two practical notes for bulk buys: pick a model with a retractable or swivel cap — the ADATA DashDrive and Kensington swivel drives here — because loose caps get lost within a week. And if the drives are going out with data on them, check the write speed before you commit; copying to fifty slow drives takes an afternoon. A sheet of labels is worth adding if the set needs identifying.

Frequently asked questions

How much can a 64GB USB drive hold?

Roughly 15,000 high-resolution photos, around 10 hours of 1080p video, or effectively unlimited office documents. Usable capacity is always slightly less than the advertised figure because storage is measured in decimal gigabytes and operating systems report binary — a 64GB drive typically shows about 59GB.

What's the difference between USB 2.0 and USB 3.0 flash drives?

Speed. USB 3.0 transfers data roughly ten times faster in real use. USB 3.0 drives still work in USB 2.0 ports at the slower speed, so there's no compatibility reason to choose USB 2.0.

Do I need an encrypted USB drive?

If personal information, client data or financial records ever leave the office on it, yes. Under the Privacy Act 2020 a lost unencrypted drive holding personal information can be a notifiable breach. Hardware-encrypted drives like the Kingston IronKey enforce this on the drive itself, so it works on any computer without installing software.

Why won't my USB drive accept a file over 4GB?

It's formatted as FAT32, which has a 4GB per-file limit. Reformat it as exFAT — that removes the limit and still works on both Windows and macOS. Reformatting erases the drive, so copy anything off it first.

What's a dual USB-C flash drive?

A drive with two connectors — standard USB-A on one end and USB-C on the other — so it plugs into both older desktops and newer laptops, tablets and phones without an adaptor. The Netac US11 and US18 in this range are dual-type. For larger or longer-term storage, an external hard drive or a memory card may suit better.
