I have toyed around with building a rack-mount or closet datacenter in my home for years, but never could convince myself to spend all that money. With the huge price reduction on these 14TB drives, I decided to buy the Synology 1821+ instead, 8x of the WD EasyShare 14TB drives that were on sale from BB, as well as upgrades in RAM and NVME cache for the DiskStation. I still have a few more days of stress testing left on the drives before I perform the physical shuck, but so far everything is coming along well. I currently have 10x (6-8TB) drives across two desktop machines with JMicron RAID controllers (in RAID5 configurations.) The majority of my media is game ROMs, movies/TV shows, and music, totaling around 35TB. I have never owned a dedicated home NAS box like this before, so this will be my first time managing a non-windows device for some external sharing.
Primary use will be for media storage/streaming. Although I have CAT7 cables running to the vital areas of the home, I do not own any 10GB network cards yet, nor do I think I have a need since there would usually only be one user accessing data from the array at any given time. I understand that this model DiskStation is not exactly stellar at transcoding 4k videos, so in the future I will likely add a NUC or some other external transcoder, and for now will just be using a laptop connected to the TV via HDMI, while reading the data from the network.
Secondary use will be as a dataserver for myself and parents, primarily to archive family photos, important documents, etc, as well as to allow them to download/upload these from multiple residences. Currently I run a FileZilla FTP server from one of the PCs for this purpose, but would be keen to migrate it to this DiskStation.
So my questions:
1: Does any of the above scream any obvious “NO’s!” from the /DataHoarder community?
2: Aside from taping the 3.3v pin (out of a sheer abundance of caution) is there anything else I should do to these drives before/after shucking but before placing them in the DiskStation? (Format, block size, etc)
3: After my first RAID0 and RAID1 arrays in the early 2000’s, I have solely used RAID5 and never looked back. Should I try Synology’s proprietary raid or another level, or is RAID5 still safe enough for my use?
4: Do you find the onboard firewall sufficient in the 1821+? I loathe the idea of changing current router/network settings.
5: What about the onboard FTP software? I would only have user accounts for less than 20 people total, with many never accessing the device, ever.
6: Btrfs, ext4, NTFS. The white paper for the DiskStation states that “internally” it supports Btrfs and ext4, while “externally” it supports those and other filesystems (such as NFTS that I currently use for most everything.) Has anybody had luck with the auto-checks/repairs (file healing) inherent with Btrfs and this device? Pros and cons?
I know this is a lot, and probably covered in other threads, but I feel a lot of attention is on these particular drives at the moment, so hopefully someone can help myself, and perhaps other lurkers out by tacking one or more of my questions.
