THE READ
What the cluster adds up to.
The Alronly portable USB DVD writer now bundles a 2.5-inch SATA dock and an SD card slot alongside its CD/DVD read/write capabilities. It retains the ability to read CDs at up to 24X speed and write DVDs at up to 8X speed. The device also provides two USB-A ports, one USB-C data port, and a separate USB-C power connector. All these features are housed in a 0.9-inch thick, 0.75-pound black enclosure.
At $26.99 after a 10% discount, the drive offers a low-cost option for engineers who need occasional access to optical media. Because it is plug-and-play with no driver installation required, it can be connected to a Windows, Linux, or macOS workstation and used immediately. The built-in SATA dock lets a 2.5-inch HDD or SSD be attached via USB 3.0, providing up to 5 Gbps transfer for data migration or backup tasks. The SD/microSD slot adds quick access to removable flash storage without needing a separate card reader.
The drive is explicitly stated to be incompatible with iOS, Android, and ChromeOS devices. It includes a dedicated USB-C power connector that can be used when the host’s data port does not provide sufficient power. The device’s cable combines USB-A and USB-C connectors for data and power, allowing flexible connection to various hosts. These characteristics make it suitable for accessing old discs, copying files to SD cards, or attaching a 2.5-inch SATA drive via USB 3.0.
