Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.

The DS1817 does best with the server grade helium disks which run at 7200 rpm. The reason is that the disks are far better suited to storage array uses than consumer grade disks which tend to fail quickly. The DS1817 disk cages are easily removed and disks can be exchanged fairly easily.

The DS1817 is designed to tolerate one disk failure so its advisable to have at least 2 spare hard disks as failures tend to be frequent once the fist disk dies. Hard disks can usually reach 60,000 power on hours fine before they start to fail due to wear out. Its advisable to swap disks slowly for introducing new capacity models so that the NAS can migrate the data.

For those using drive managed shingled disks the DS1817 will work with Seagate disks but problems with WD disks which do not resilver properly. WD Gold disks are better quality but they are a small segment of the market compared to Seagate and Toshiba. WD Red series which are designed for NAS units should be less of a problem but server grade disks are ideal.
