Netstor 2U rackmount 8-bay Thunderbolt 3 hardware RAID storage

Netstor NA341TB3 rackmount 2U 8-bay Thunderbolt 3 RAID storage

The Netstor NA341TB3 is a 19" 2U rackmount storage system with eight bays and a built-in hardware RAID controller, connected to the host computer or workstation over Thunderbolt 3 at 40 Gbps with data rates up to 2750 MB/s. It accepts SAS or SATA 12/6 Gb/s drives, 3.5" HDDs as well as 2.5" HDDs/SSDs. In Netstor's AJA test in RAID 5 it reached 1195 MB/s write and 1398 MB/s read.

The RAID-on-Chip controller with 1 GB ECC cache supports RAID 0, 1, 10, 3, 5, 6, 30, 50 and 60 and is set up through a web GUI, which also sends e-mail event notifications; a buzzer sounds when a component fails, and a red LED (SGPIO) marks the failed drive for replacement and rebuilding. Key locks on each tray prevent removing the wrong drive. Two inner 60 mm fans and two rear hot-swappable blowers cool the cold-rolled steel chassis, powered by a 400 W server-grade supply.
