Synology DiskStation DS409

The Synology DS409 software updates were stopped at version 4.3 of Disk Station Manager. Our Synology was updated to version 5.x using the method listed here:

The Synology believes it's a DS411j with ESATA enabled.

The DS409 presently has 2 disks installed. 1 is 1TB, 1 is 500GB. Mike Grube has volunteered and additional 2x 1TB drives. Presently the accessible storage is limited to 500GB. With the two additional drives installed accessible storage will be limited to 1.5TB mirrored and 500GB non-mirrored.

Disk configuration

The disks are configured in RAID 6. This uses two parity stripes on each disk. It allows for two disk failures before data is lost.

Accessible disk space:

Total space

4TB Striped and mirrored

Total member space

50GB AHA Read Only Share 100GB Shared space (erased daily) 20GB of space allocated per member


User Share

Each member is given 20GB of space on the NAS. The member space is backed up locally each evening and mirrored to an offsite NAS once a week.

If a member stops paying membership their user shared files will be erased after 3 months. If space on the NAS runs low we may remove expired accounts sooner.

Space Shared

This is a space shared between all machines that login using AHA images. It's also mounted to AHA Virtual Box Ubuntu images. It can be used a temporary space to store items and transfer them between machines as you work.

100GB are allotted to this space.

This space is wiped by the NAS nightly at 3:01AM.

Software Share

This share is mounted at login to the windows workstations. It is read only from the workstations. It is populated with software that is used at AHA and the specific versions used.
