Built for makers and mobile professionals

The Samsung T7 MU-PC4T0T/AM is a 4 TB portable SSD that uses PCIe NVMe over USB 3.2 Gen 2. It targets creators, students and professionals who need fast, compact external storage for large media libraries, game installs or project backups. The drive works with Windows 7 or higher, Mac OS X 10.10 or higher and Android Lollipop or higher.

Sustained speed under continuous load

Sequential reads reach up to 1050 MBps and writes up to 1000 MBps, nearly twice the throughput of the previous T5. The 3D V-NAND 3-bit MLC memory maintains these rates during extended transfers such as 4K 60fs video recording or bulk file migration. Thermal throttling may reduce performance during very long, uninterrupted writes.

Simple plug-and-play setup

The drive requires no external power or driver installation on supported operating systems. Its compact 2.20 by 3.40 by 0.30 inch form factor and 0.13 lb weight fit easily in a pocket or bag. The main installation issue is using a USB port or cable limited to 5 Gbps, which caps the drive well below its rated speed.

Questions about this item

Does the T7 4TB run hot or draw much power during all-day video editing?

The drive uses PCIe NVMe technology in a compact 0.30" metal enclosure that acts as a heatsink; with no moving parts it stays cool and draws only bus power from the USB 3.2 Gen 2 port.

What host port and OS do I need before the T7 4TB will work?

You need a USB 3.2 Gen 2 Type-C or Type-A port and Windows 7 or higher, Mac OS X 10.10 or higher, or Android Lollipop or higher.

Can I keep using my older USB 3.0 hub with this T7 4TB?

Yes, the drive is backward compatible with USB 3.0 and 2.0 ports, though sequential speeds will drop to the hub's maximum instead of the rated 1050 MBps read and 1000 MBps write.
