Synology HD6500 60-Bay Rackstation NAS FINALLY RELEASED!

Synology HD6500 60-Bay Rackmount NAS Released

Synology announces the availability of the HD6500, the first of the HD series, designed for super-sized storage needs. The 4U, 60-bay HD6500 streamlines petabyte-level storage with support for up to 960 TB per chassis and can be easily paired with up to 4 additional RX6022sas 60 bay expansion units for over 4 PB of storage in 20U. HD6500 can deliver over 6688 MB/s in sequential read, and 6662 MB/s in sequential write¹, making it an extremely capable solution for scenarios requiring massive quantities of data such as large-scale storage for studios, large-scale video surveillance backup, and enterprise office PC backup.

“An HD6500 system is really pushing the boundaries of scalable storage,” said Jason Fan, Product Manager at Synology. “The simple nature of it, practically plug and play, makes it easy to integrate into any existing IT environment, no additional training needed. Running DSM 7.1, HD6500 features the same comprehensive data management and backup solutions that our customers currently heavily depend upon, but now in a super-sized package.”

Massive scalability with reliable performance

Designed specifically for use with Synology HAS5300 SAS HDDs, the HD6500’s storage controllers, firmware, and operating system have been optimized and thoroughly validated for long-term performance reliability and data integrity. The inclusion of dual power supplies, SAS multipathing support, out-of-band management support, and dual independent system drives provide redundancy to ensure consistent and dependable data and service availability. 

Flexible connectivity options

With two 10GbE RJ-45 ports, three Gigabit Ethernet ports, and the ability to expand up to 10 additional 10GbE SFP+/RJ-45 and 25GbE SFP28, or Fibre Channel ports, the HD6500 is equipped to scale with business demands.


Synology HD6500 is now available through Synology’s solution partners and channel networks. For additional information on HD6500, please visit the links below

      1. Can I use WD UltraStar HC550 18 TB SATA Drives in the Synology HD6500 SAS Chassis?
        Looking to purchase one of these if I can put SATA Drives instead of SAS Drives into this Chassis.

      2. Can I use WD UltraStar HC550 18 TB SATA Drives in the Synology HD6500 SAS Chassis?
        Looking to purchase one of these if I can put SATA Drives instead of SAS Drives into this Chassis.

      3. Hi gang! A MASSIVE amount of new information has arrived on the HD6500 hardware architecture, software support, expansion deployment and more. I have updated the news article with info and images, so you can find it here –

      4. I’m surprised that this only comes with 2 10gbit ports. For something with this much storage, I would have expected more, as I expect the network card is probably going to be the bottleneck

      5. From an integration pov this might be interesting. Outside of that, one can do _much_ better $/TB-wise w/any roll-your-own hw w/TrueNAS and readily available Dell MD3060E units off of eBay. Dual path standard external SAS 60 bay (5 12 drive trays). Further, the above can be had now, whereas who knows how much longer Synology is going to bake the hd6500.

        Will be neat as a curiosity though.

      6. I know a company that rents out camera systems for training ai systems (think self driving cars) tha can collect 200tb of data every 24 hrs of operation

        There’s a 6-8 month waiting list to rent the system

        The demand is there. If you’re paying that much to collect the data you’ve got triplicates of everything

      7. Love your passion for these mythical beasts! This one unit has more drive slots than Synology has its own branded HDD ???? would be a monster even just to put slower and high capacity 3.5 SSD

      8. Really like your in depth videos.

        What are your thoughts on Ultrastar vs Exos (18tb) drives for a Truenas build?
        The Ultrastar drives are slightly more expensive where I live.
        Wondering how they compare in regards to power consumption, performance, reliability etc.
