The skyBOX is a "credit-card-sized" wireless portable SSD that is now available on Indiegogo
The skyBOX is the latest in an ever-growing line of portable SSDs on crowdfunding sites. However, its maker the HyperAccessory team claims to set it apart with exceptionally up-to-date and powerful specs. The device is to be outfitted with the Broadcom BCM43684 chipset, so as to confer Wi-Fi 6 on the new drive. This may support effective content-streaming and wireless data-transfers on the 55x85 millimeter (mm, or 2.2x3.3 inches (in)) box.
HyperAccessory also asserts that USB type C 3.2 Gen 2 2x2 speeds (20 gigabits per second (Gb/s)) are possible with the skyBOX. However, this apparently only applies to its top-end 4TB SKU. It also has 512GB, 1TB and 2TB options without this feature. All of these variants have NVMe M.2 SSDs, and feature 1 USB type A and 1 type C port each. Both of these have up to the 3.2 Gen 2 specification, which is associated with the 20Gb/s limit.
The skyBOX also has an SD card slot, served by a button for "one-touch copy" from this medium. It is rated for the UHS-II standard, and, thus, transfers of up to 300MB/s. It is now available as a reward on Indiegogo, where it has attracted nearly US$170,000 (correct at time of writing). It starts at $99 for a 512GB drive, although this goes up to $469 for one with the largest 4TB capacity.
