What this drive does
The Rocstor RocPort 4U is a portable 2.5" external hard drive with 120GB capacity and a 5400 RPM mechanism. It connects through a single USB 2.0 cable and requires no external power supply or driver installation. The aluminium enclosure acts as a passive heatsink, so the unit runs without a fan. It is suited to users who need a compact, bus-powered volume for moving documents, backups or media between computers.
Check your ports and cable
The supplied cable is 3.28 ft long and terminates in USB Type-C plugs on both ends. Your host must provide a USB Type-C port that supports USB 2.0 data signalling; a USB-C port that carries only power will not work. No separate driver is needed for Windows, macOS, Chrome OS, Android or iPadOS, but the host operating system must be able to mount a standard mass-storage device formatted with a filesystem it recognises.
Heat, noise and power in use
Because the aluminium case dissipates heat passively, the drive produces no fan noise during normal operation. Power is drawn entirely from the host USB port, so the load on that port equals the drive's own consumption. The 5400 RPM spindle and 8MB cache yield a practical transfer rate of up to 60 MB/s, which is the ceiling set by the USB 2.0 interface rather than the mechanism itself.

Questions about this item
Does the B153E5-01 include the USB 2.0 cable or do I need to buy one separately?
The drive comes with a 3.28 ft USB 2.0 Type C male-to-male cable so no separate cable purchase is required.
The listing shows only one capacity — is the 120GB 5400 RPM model the only option?
Yes, the RocPort 4U series is offered in this single 120GB 5400 RPM configuration with 8MB cache.
What real-world transfer speed can I expect from the 60 MB/s headline figure on a laptop?
The 60 MB/s rating is the interface maximum; actual throughput will be lower and depends on file sizes and the host system.
