Synology NAS Disk Station DS411j 4 Bay - 12TB Network Attached Storage has been a reliable NAS for my home network. 

- Supports both HDD and SSD drive types and has a write speed of 4x. 

- 4 bays and an included storage capacity of 12GB (3x 3TB and 1x 4TB)

- Interfaces: USB, Ethernet, and SATA II.

- Unit ships with 12TB of storage that has been formatted and are healthy.

--  3x 3TB Seagate Barracuda 3TB Hard Drive

--  1x Seagate IronWolf 4TB NAS Hard Drive

- Latest Synology OS has been re-installed after Mode 2 reset (6.2.4-25556 Update 7)

I am the original owner and have had no issues with this NAS. 

Decided it was time to upgrade to the DS918+.

Thanks for looking!
