Sharge Disk Pro 2: Portable SSD Doubles as a 4K HDMI Dock

The Sharge Disk Pro 2 Ultra is emerging as a versatile gadget, merging a portable solid-state drive with a 4K HDMI dock and USB-C hub. Aimed at users seeking a streamlined tech experience, this device targets compatibility with a wide range of modern electronics including laptops, tablets, smartphones, and even gaming consoles like the Nintendo Switch and its anticipated successor, the Switch 2. Its compact design, comparable to a deck of playing cards, incorporates MagSafe-compatible magnets for attachment to compatible phones.

The Disk Pro 2 Ultra boasts an impressive array of features designed to expand device connectivity. It provides a single 4K 144Hz HDMI 2.1 video output, a 5Gbps USB-A port, and slots for both SD and microSD cards. Additionally, it supports USB-C passthrough charging and can accommodate up to 8TB of storage via an M.2 2280 (or smaller) NVMe SSD. During testing, a single connection to a MacBook Pro enabled a second external monitor, access to multiple storage sources, and 80W of USB-C Power Delivery. The drive also proved capable of connecting to and displaying content from smartphones on an external screen, even unlocking 4K60 ProRes video recording on certain iPhone models.

Expanding Capabilities and Power Considerations

While the Sharge Disk Pro 2 Ultra offers significant functionality, its performance is tied to power requirements. Sharge is offering two models: the "Ultra," which needs a minimum of 1.5W of USB-C bus power, and the "Lite," requiring 5W and supporting 4K60 over HDMI 2.0. For the Ultra model, Sharge marketing manager Leo H. explained that only 3W of power can be routed to the SSD from the host device. This limitation can cause shutdowns during demanding tasks like ProRes video recording or large file transfers on high-power smartphones. Sharge recommends connecting an external USB-C battery or charger to the Disk Pro 2 to ensure stable operation during these intensive uses. Finding a lower-power SSD is also a potential workaround.

Compatibility with Nintendo consoles presents another unique consideration. Both the original Nintendo Switch and the Switch 2 require a relatively specific external power source for successful docking. Sharge is actively working on firmware updates but currently advises using an 85W or higher USB-C PD charger specifically for the Switch 2. Users may also notice a delay before the consoles appear on a connected television, a characteristic shared with some other third-party docks. Furthermore, variable refresh rate (VRR) support is not guaranteed with devices like the Steam Deck, despite the drive's capability for 4K144Hz and 4K120Hz with HDR.

Despite minor hurdles, the Disk Pro 2 Ultra represents a significant improvement over previous Sharge models. Early iterations like the original Sharge Disk were criticized for bulky design and noisy fans, while the Disk Plus struggled with its magnetically attaching accessory. The first Disk Pro model faced issues with a recessed power port and power-cutting buttons. The Disk Pro 2 addresses these concerns with a detachable cable, integrated magnets, improved port accessibility, quieter fan operation (with an off option), and a more robust power switch. The inclusion of a larger airflow path and the option for users to supply their own M.2 SSD contribute to its enhanced usability. While the fan's impact on transfer speeds is minimal, it plays a crucial role in thermal management, preventing the device from overheating during sustained use. Early bird pricing on Kickstarter for the Disk Pro 2 Ultra is set at $75, with a planned retail price of $89, making it an accessible option for users seeking advanced connectivity.
