Seagate has been busy lately. They’ve just updated their BlackArmor line with three new units, a 220 NAS that holds up to 4TB, a WS 100 external drive with eSATA and USB 2.0, and a PS 110 portable drive that holds up to 500GB.

The Seagate BlackArmor NAS 220 is available in late July for $449.99 for 2TB and $699.99 for 4TB. The Seagate BlackArmor WS 110 is available now at $159.99 for 1TB and $309.99 for 2TB. The Seagate BlackArmor PS 110 is also available now for $159.99 for 500GB.

External storage is particularly important in the business world where the loss of data can mean the loss of significant money or important records that can’t be replaced. For that reason businesses often spend lots of money on external storage solutions. Seagate has announced new NAS devices that are more affordable than the average solution.

The new products are in the BlackArmor line and include the NAS 440 and NAS 420 storage servers, which can support up to 8TB each. Both of the devices are four bay, hot swappable units that offer a centralized way to backup and secure data in a business or home. The NAS 420 ships with two drives installed with 2TB of total capacity. The NAS 440 comes with four drives installed and capacities up to 8TB.
