Samsung T9 Portable SSD 4TB Black
Why choose it
Choose the 4TB T9 for a compatible USB 3.2 Gen 2x2 host when you want a large portable library. This capacity is rated for up to 2,000 MB/s reads and writes; a slower host connection limits throughput.1 The T9 supports hardware encryption and has a five-year limited warranty. Its three-meter drop rating comes from controlled testing; drop damage is excluded from warranty coverage.1
Before you buy
Check that your computer has a 20Gbps USB 3.2 Gen 2x2 port before paying for the extra speed. USB-C describes the connector, so it does not establish the port's transfer rate.1
