Capacity and included reader

The TOPRAM TR16GSDUHS1R3 is a 16 GB SDHC card rated for UHS Speed Class 1. It ships with an R3 USB reader so the card can be used immediately with any computer that has a free USB port. The bundle suits photographers or videographers who need a ready-to-go storage and transfer kit.

Thermals noise and power

As a solid-state memory card the unit has no moving parts and generates no audible noise during operation. Power is drawn entirely from the host USB port so there is no external supply to manage. Typical surface temperature remains low enough for comfortable handling even after extended read or write sessions.

Build and daily connectors

The card uses the standard SDHC form factor and the reader presents a USB 3.0 Type-A plug that also works in USB 2.0 sockets. Insert the card into the reader then plug the reader into the computer; the combination appears as a removable drive with no driver installation required. This plug-and-play workflow lets you offload footage on location or at a desk without extra cables or adapters.

Questions about this item

How do I install the TOPRAM 16GB SDHC card and the included R3 reader, and what step is often missed?

Insert the card label-side up until it clicks, then plug the R3 reader into a USB 3.0 port; the step often missed is using a USB 2.0 port, which limits read speed to 20MB/s and write to 15MB/s instead of the 50MB/s read and 20MB/s write available on USB 3.0.

What maintenance or replacement will the TOPRAM 16GB SDHC card need over time?

The card has no moving parts and requires no scheduled maintenance; replace it only if it fails or when you need more than the 16GB capacity or faster speeds than the UHS Speed Class 1 rating provides.

What limit appears first when I write continuously to the TOPRAM 16GB SDHC card?

The write speed ceiling of 20MB/s on USB 3.0 is the first limit reached during sustained writes; on USB 2.0 the ceiling drops to 15MB/s, so the interface speed determines the bottleneck.
