220
PLUSTJA

The next step up from the popular DS920+, is this DS1621+. By all accounts it is an upgrade in every respect except for hardware transcoding for Plex. I don't need transcoding as I direct play with a Shield. Haven't seen it this cheap in recent times, from what I can tell.

Number of Bays: 6
CPU: Ryzen V1500B
CPU Clock Speed (GHz): 2.2GHz
CPU Number of Cores: 4

  • Wow great price for this new model. I'm rocking the previous gen ( DS1618+ ) and it's been great.

  • If you can afford the 8 bay version I’d go with that.
    6 drives with 2 parity = 66% efficiency (4/6 drives)
    Whereas 8 drives with 2 parity is 75% efficiency.
    I’ve got an 1819+ Full of 16TB drives which gives me a bit over 80TB.
    Looking to get a second spare chassis before synology start restricting you to their own drives only (which would double my storage price).

    • What does 2 parity mean?

      • Can afford to lose 2 drives and you can still rebuild your array.

      • RAID6 requires 2 parity blocks thus allows up to two drives failures at the same time. In 6 drives config, usable drives would be 6 - 2 = 4. The rest of the math was already there.

        Personally I would never go rebuild a RAID ever again as it simply not worthy doing so in home usage scenarios.

      Do you have a particular reason to waste drives on parity ?
      You need a robust backup strategy anyway - may as well just use it when you get a drive failure, rather than wasting masses of space just to minimise downtime 🤷🏼‍♂️

    • Thanks for the tip - canceled my order and went for the 8 bay which is not much more!

  • Hey guys, I want to edit videos, along with making a Plex server, and everyone on YouTube says get the 1621+ over the 920+.

    What I don't under is this 10Gbe business. Do I need to buy extra things for it? Does it also mean my device needs to connect to it direclty?

    Thanks

      I have the DS1621+ and bought 2 Mallenox 10Gbe PCIE cards and SPF cable to direct connect my PC to the NAS.
      https://www.ebay.com.au/itm/144111022642

      So the NAS is connected via standard 1 Gbe to the switch/router for the whole family, and my main PC has direct 10Gbe connection to the NAS.

      This is the cheapest way. Of course you can buy a 10Gbe switch to do it properly.

      • Hi, why did you need 2 of them and can you install both into the single 1621+?

        • One for the DS1621+ and one for my PC, then use the SPF cable to direct connect them.

      • Thanks for the pointer on the Mellanox cards - I just grabbed one of the DS1821+, so these will work well with the 10G SPF+ switch we have. Have you done anything with the RAM on yours? If so did you find a good source? Cheers.

    For those who don't mind building your own, it's MUCH cheaper to simply use an old PC case and buy some cheap parts (or reuse old second hand ones) to make your own DAS - direct attached storage.

    https://forums.serverbuilds.net/t/guide-direct-attached-stor…

    Hook it up to the main computer with SAS cables directly into an LSI-9201-16e card (about $85 on Ebay, buy from a reputable seller like this https://www.ebay.com.au/itm/234314231438?frcectupt=true, flash it in IT mode) and for ~$300 you'll have up to 16 drive slots to use. Put in any old hard drives you have, I have a varied mix of larger 12TB down to 1TB drives from over 10 years ago.

    Use SFF-8088 (SAS to 4x SATA) cables to connect the drives to the LSI card. https://www.amazon.com.au/Baosity-SFF-8088-SATA-Mini-SAS-Cab…

    A backup strategy means I don't care for parity, but you can easily pool all the drives together into a single drive letter using something like Stablebit Drivepool. Or just use your own software RAID if that's what you prefer.

    I use 3 of these drive cages and they work perfectly fine. https://www.ebay.com.au/itm/185187315358
    But the case you use will probably have its own spots for 3.5" storage so you can also use those.

    Been running this setup 24x7 for over 2 years without any issues. Currently at 86 TB storage but still have 7 slots free to upgrade in the future when larger HDDs become cheaper.

      I went this route many years back with an HP ML10 and Drivepool. But I've got less time these days for diagnosing issues and maintaining it, so hence will relegate it to simple backup duty and use this new NAS as the primary source.

      It really depends on your budget and how much time you want to spend on trouble shooting.
      I enjoyed spending days on why my build did not work but now it becomes a luxury.

      I'll be honest.

      I have no idea what you wrote about the first link. It's like a foreign language. I feel like Homer at the Computer Store.

      I just want to edit my videos without 20 hard drives, that's all.

    • This is a great option if so inclined. I did similar many years ago running my own custom built file servers and pcs but i just CBF anymore. Maybe it's age, valuing my time more, or just losing interest to fiddle about, dunno. I bought a Synology 918+ 2 years back and love it, keen to get another or a bigger one. Like buying a TV, i'll wriggle at the seemingly abhorrent cost but a week after buying it won't give it a second thought.
