Related Questions and Answers

Q: 1. Can this be used as a regular old RAID drive rather than a NAS? or is there a better solution for a large RAID drive?

A: The Synology 48TB DiskStation DS1821+ 8-Bay NAS Enclosure Kit with Seagate NAS Drives (8 x 6TB) can be used as a local raid, but it's limited to USB 3.1 Gen 1 speeds as the enclosure is primarily intended as a NAS. For a local RAID, I'd recommend the SanDisk Professional 48TB G-RAID Shuttle 8 8-Bay RAID Array (8 x 6TB, Thunderbolt 3 & USB 3.2 Gen 2) (B&H # SAGRS848TB).

Q: 2. Does it come with the drives installed and configured, or just bundled to purchase? Also, are the discs hot swappable?

Q: 9. To connect this to a MBP M1 Max, and use it for video editing, what other components do i need?

Q: 10. Even with 10 GBps ethernet, no matter what RAID configuration I setup for this system, the max download speed I get is 180 MBps?

A: There are many factors that affect data rates of a given NAS setup. The Synology 60TB DiskStation DS1522+ 5-Bay NAS Enclosure Kit with Seagate IronWolf NAS Drives' (5 x 12TB) data rate will depend on the RAID format you choose, the speed of your network switch, possibly your internet speeds if accessing remotely via the internet, if you add a network card to the switch, the drive's speed, the number of people accessing the NAS at a given time, the added M.2 drives/RAM, and the network connection speed of the computer that you are accessing the NAS from. All parts of the network must be up to speed to support a given data rate.
