Rugged 4TB portable drive

The SanDisk G-DRIVE ArmorATD provides 4TB of storage in a 2.5-inch form factor built for harsh environments. It targets photographers and videographers who need reliable offline backups while travelling or working on location. The drive connects via USB-C with Thunderbolt 3 support for broad host compatibility.

Sustained transfer up to 140MB/s

Sequential throughput reaches 140MB/s, allowing large media libraries to move steadily during extended ingest sessions. The mechanical spindle maintains this rate across long writes without the thermal throttling common in compact solid-state alternatives. Performance stays consistent until the 4TB capacity is filled.

Aluminium enclosure with rubber bumper

A premium aluminium chassis houses internal shock mounts rated to withstand 1000lbs of crush force. The easy-grip rubber bumper adds drop protection and a secure hold in wet or dusty conditions. USB-C connectivity means a single reversible cable handles both data and power on modern laptops and desktops.

Questions about this item

How much heat or noise does the 4TB drive produce when it runs all day?

The 2.5" mechanism has no fan, so it stays silent and generates only the low heat typical of a spinning drive under sustained use.

What host port must my computer already have to use the USB-C cable supplied with the SDPH81G004TGBA1D?

A USB-C port is required; the drive also works with Thunderbolt 3 hosts through that same USB-C connection.

Will the 140 MB/s transfer rate of this drive be bottlenecked if I connect it to an older USB-A port via an adapter?

Yes, a legacy USB-A port will limit throughput well below the drive's 140 MB/s capability.
