ZikeTech is a crowd-funded peripherals startup, which claims to have the "world's first and fastest USB4 SSD." The ZikeDrive is a portable SSD that features an extruded aluminium chassis that doubles up as a heatsink for the M.2 NVMe SSD underneath. The drive features a M.2-2280 slot with PCI-Express 4.0 x4 connection, and a bridge chip that converts this to a 40 Gbps USB4, giving it slightly more bandwidth than PCI-Express 3.0 x4 (32 Gbps). This allows a PCIe Gen 4 NVMe SSD to have sequential transfer speeds of up to 3.8 GB/s. The ZikeDrive starts at $99 for the bare enclosure, or with pre-installed 1 TB, 2 TB, or 4 TB drives that offer sequential speeds of up to 3763 MB/s reads, with up to 3146 MB/s writes; however, it is currently an Indiegogo project.
