Shipping, as usual, fast and perfect. The DiskStation came with the latest version of DSM 3.0. Newer Version (DSM_DS411j_1594) was available only one week later, they have the same downloaded and installed. With 4x 2TB disks there should be some time rich (teaches about 5,9TB RAID5). Transfer rate with RAID 5 about 33MB / s Completely satisfied.
