Sharge Launches $75 Disk Pro 2 Ultra With 4K144 HDMI and Up to 8TB SSD Support

Q: Despite supporting massive 8TB drives, why did Sharge intentionally bottleneck the Disk Pro 2 with older 10Gbps technology instead of USB4?

Sharge appears to have chosen 10Gbps USB-C on purpose to keep the Disk Pro 2 small, cheap, low-power, and broadly compatible, rather than to maximize raw SSD speed. The product’s real job is not just storage. It is a compact dock that has to handle HDMI output, card readers, USB-A, passthrough charging, magnets, and cooling while working from phones, tablets, laptops, handhelds, and even iPhones for ProRes recording. In that context, USB4 would have raised cost, heat, controller complexity, and power demands in a device that already faces tight power limits. The Ultra model can supply only about 3W to an SSD when running from a host device, and some high-draw drives already risk dropping offline during heavy transfers. A faster USB4 design likely would have made those power and thermal constraints harder to manage. Price also matters. At $75 on Kickstarter and $89 retail for the Ultra, Disk Pro 2 is far below typical Thunderbolt or USB4 dock pricing. Comparable high-speed docks often cost several times more and are much larger. Sharge’s measured write speed of about 700MB/s is consistent with a 10Gbps enclosure and is already enough for the use cases it is targeting, including large file transfers and 4K60 ProRes capture on iPhone. The 8TB figure is about capacity, not interface speed. Supporting a large M.2 drive lets users carry more footage and files, but it does not require USB4. Sharge seems to have prioritized portability and reliability over headline bandwidth.

Q: Sharge's Disk Pro 2 promises single-cable freedom, but what hidden power flaw might force you to carry extra chargers anyway?

The catch is power delivery: the Disk Pro 2 Ultra can pass only about 3W to the installed SSD when it is being powered just by a phone or laptop, which may not be enough for some drives under heavy load. In practice, that means the “single-cable” setup can break down during demanding tasks such as large file transfers or 4K60 ProRes recording on an iPhone. Reviews and Sharge’s own guidance indicate that higher-power SSDs can disconnect or shut down unless you add external power. So the hidden flaw is not basic compatibility, but limited bus power to the SSD. If your M.2 drive draws more than that during writes, you may need to plug a charger or USB-C battery into the Disk Pro 2 anyway, undermining the all-in-one, cable-free appeal. There is a second power-related caveat for gaming use: Sharge says Nintendo Switch 2 dock support may require an 85W or higher USB-C PD charger attached. That means some users could end up carrying a power brick not just for stability, but to unlock docking at all. The practical takeaway is that the Disk Pro 2 works best with lower-power SSDs or with external power on hand. Without that, its headline promise of one-cable convenience may not hold in the most demanding scenarios.

Q: What underlying technical compromise causes the Disk Pro 2 to suffer from display dropouts and missing VRR during handheld gaming sessions?

The likely cause is a bandwidth and signaling tradeoff in the Disk Pro 2’s single-cable USB-C dock design: it has to split a limited USB-C/DisplayPort Alt Mode link between video output, USB data for the SSD and ports, and power delivery, then convert that display signal to HDMI. That compromise can break features that handheld gamers expect from a direct display connection. VRR usually depends on the full display chain—source device, dock chipset, cable, signal conversion path, and monitor—all supporting variable refresh signaling. Many compact USB-C docks, especially ones converting DisplayPort-over-USB-C to HDMI, do not reliably pass through VRR even if they can handle high fixed modes like 4K120 or 4K144. The reporting around the Disk Pro 2 fits that pattern: it can drive high-resolution, high-refresh output, but not the variable refresh handshake some handhelds use. The same shared-link design also helps explain the brief display dropouts. When video bandwidth is being pushed while the dock is also handling storage traffic and power constraints, the signal margin is tighter. Any instability in the dock’s controller, firmware, cable quality, or HDMI conversion can cause momentary renegotiation or sync loss, which appears as a display dropout. In short, the device prioritizes an all-in-one, low-power, portable dock over a direct, gaming-optimized display path, and that technical compromise is what likely leads to missing VRR and occasional display interruptions.

$75 Disk Pro 2 Ultra combines a magnetic portable SSD enclosure, 4K HDMI dock and USB-C hub in a pack-of-cards design, with support for up to 8TB M.2 storage.
4K144 HDMI 2.1, a 5Gbps USB-A port, SD and microSD readers, and USB-C passthrough let it drive a second monitor, attach multiple storage sources and power a laptop at up to 80W.
1.5W bus power on the Ultra keeps the dock highly portable, but its 3W SSD power budget caused shutdowns during iPhone 15 Pro ProRes recording and large phone transfers unless external power was added.
85W USB-C PD is still needed for Switch 2 docking, VRR did not work with Steam Deck, and the reviewer saw occasional display dropouts, showing firmware and compatibility work remains.
Sharge says the model fixes earlier Disk flaws with built-in magnets, a detachable cable, quieter cooling and safer controls; Kickstarter pricing is $75 early bird before an $89 retail price.
