RAID is pre-configured and the unit includes 16 GB of DDR4 memory. A native 10 GbE port and multi-gigabit Ethernet standards provide high-throughput connectivity without cable upgrades.

Small-business teams needing turnkey capacity

This system suits organisations that want a ready-to-rack file server with cloud-sync support for Amazon S3, Dropbox, Microsoft Azure and OneDrive. It is not intended for buyers who require more than twelve drive bays, who need a different drive interface than SATA, or who plan to run workloads outside the listed Windows, Windows Server and macOS versions.

80 TB raw capacity in four pre-installed drives

The array delivers 80 TB of raw storage across four 20 TB drives with RAID 0, 1, 5, 6, 10 and JBOD options. This capacity figure determines whether the appliance matches the data-retention and redundancy requirements of the target deployment.

Questions about this item

How often will the four 20TB drives need replacement in a RAID 6 array?

The 20TB enterprise drives are rated for continuous operation; replace any drive that SMART reports as failing or after the manufacturer's rated service life.

What limits sustained write throughput on the 10GBASE-T port?

The 10GBASE-T network interface and the SATA III 6 Gbps drive links set the maximum sustained write speed.

How much heat does the 500W power supply add to a rack running all day?

At full load the unit draws up to 500W, converting most of that power into heat inside the rack.
