The ARC-8050 is a fantastic lineup of desktop RAID solutions that we have had the opportunity to test in the past. Today, Areca adds the U3 to the lineup to go alongside the T2 and T3 Thunderbolt units.
As far as aesthetics go, Areca hasn't changed much apart from the connectivity when coming from a T3 unit. The chassis is completely the same, even the rear I/O remains unchanged. That said this unit does support all of the same RAID modes as before with 0,1,3,5 and 6 along with 10 and JBOD support. The internal processor is the same dual-core 1.2GHz ROC paired with 2GB of DDR3 memory with six 12Gb/s SAS ports for drive connectivity. This unit supports write through and write back cache along with battery backup with module number ARC-6120BAT021-T3.
The drive bays do offer hot-swap functionality with support for 128 12Gb/s SAS or SATA drives using JBOD along with a single downstream SFF-8644 expansion connection. Main connectivity is pushed through Gen 2 USB 3.1 and the Type-C connection but is backwards compatible with USB 2.0 and 3.0.
MSRP of the Areca ARC-8050U3 comes in at $1199 with a three-year warranty.
