Connect up to eight SAS/SATA hard drives or SSDs to your compatible Windows or Mac system using the RocketStor 6661A-mSAS2 Thunderbolt 3 to Mini-SAS Port Adapter from HighPoint. This adapter is equipped with two Thunderbolt 3 ports, which provide bi-directional speeds of 40 Gb/s. While one port is used to interface with your host system, the other can be used to daisy-chain up to six devices together, including dual 4K displays or a single 5K display, thanks to support for DisplayPort 1.2. Thunderbolt 3 also supports 10 Gb/s USB 3.1 Gen 2 Type-C and provides 15W of power to compatible devices for charging.

In addition to the Thunderbolt 3 ports, the RocketStor 6661A-mSAS2 has two mini-SAS (SFF-8088) ports, each of which which supports four SATA III 6 Gb/s channels. Each channel is able to support one SATA hard drive or SSD for a total of eight drives, and capacities are supported up to 14TB per drive, or 112TB total. Attached drives can also be configured as RAID 0, 1, 5, 10, or 50 array, each of which provides performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD and non-RAID modes are available.

HighPoint's RocketStor 6661A-mSAS2 Thunderbolt 3 to Mini-SAS Port Adapter is compatible with Thunderbolt 2 devices, as well as USB 3.1 Gen 1 (USB 3.0), and USB 2.0 using a USB Type-C cable. Please be aware that any daisy-chain connections will terminate if a peripheral or device is connected via USB Type-C. Included is a Thunderbolt 3 cable, a 60W / 100-240 VAC external power supply, and a power cord. Protection is provided by a limited 1-year parts & labor warranty.
