Big, scalable storage for all your data

DiskStation offers massive storage capacity for storing and protecting all your files and important data. As your storage needs grow, you can easily scale up capacity by adding additional storage expansion units.

Powerful performance for intense workloads

Tailor performance to your needs with the upgradable memory or take advantage of the PCIe slot to install a 10GbE network card for blazing data transmission or an M.2 SSD adapter card for high IOPS caching.

  • Quad-core 2.1GHz CPU
  • 4GB DDR4 SO-DIMM RAM, expandable up to 32GB
  • Up to 1,151 MBps sequential reading performance
  • PCIe slot for optional 10GbE or M.2 SSD adapter
  • Up to 16 drives with two DX517 expansion units (sold separately)

File sharing and syncing

Take files on the road or easily share them with other people, thanks to Synology's easy file sharing and syncing software.

Bulletproof data backup

Ensure data remains safe by backing up your computers, servers, and virtual machines to DiskStation, and defend yourself from human-error or ransomware with the multi-version backup. Finally, avoid disaster with the ability to easily back up DiskStation to an offsite location or to any major cloud service.

Virtualization ready

With support for VMware, Citrix, and Microsoft Hyper-V, DiskStation serves as a seamless storage solution for virtualization environments. Additionally, Synology’s Virtual Machine Manager also lets you set up and run various virtual machines directly on DiskStation, including Windows, Linux, and Virtual DSM.

    An AMAZINGLY fast NAS

    An AMAZINGLY fast NAS
    I'm not going to talk about the great Operating System in Synology NAS, it's the same in all Synology Consumer NAS. My older DS211j, DS211 and DS411 still get both security and OS updates at the same time. Two thumbs up for the continued support of older models, with the notable exception of not supporting btfrs in the DS411 which I now use for backup. WHY? All the necessary drivers are included in the respective DSM.I'm only going to talk about transfer speeds which is what you may want to compare when choosing between different Synology models.I purchased the DS1618+ to upgrade from my old and slow DS411. Anything I wanted to do with the DS411 spiked CPU usage to 99%, even simple file transfers (4 disk SHR-1 configuration), which topped at about 12MB/s.Opening and closing apps was also terribly slow.On the DS1618+ I used 3 older drives (16000 to 36000 hours) from the DS411 plus 2 new drives, all Western Digital RED 4TB in a 5x 4TB SHR-2 configuration and a single Volume (12000GB total usable space) for added HDD failure robustness, since I've had 2 drives fail within 1 month on the DS411 a few years back and was barely able to finish rebuilding after the first drive failed when the second one (different make and model) failed too. Plus RAID only helps you so far, only against HDD total failure, not with corruption or bitrot.I was weary of the transfer speeds I would be able to achieve in this 5xHDD SHR-2 configuration (double parity means more CPU usage), since when I moved from my 2-bay DS211 with 2 HDD in SHR-1 to my 4-bay DS411 with 4 HDD in SHR-1, transfer speeds dropped from about 36MB/s to about 12MB/s due to the higher CPU usage. Lately this has been a pain since now I'm processing large amounts of drone images stored on my NAS.But I was blown away: Transfer speeds are as fast as Gigabit ethernet allows you to. I never thought I would see 99% usage of my GbE PC connection. Both writing and reading from the NAS to my Windows 7 x64 PC SSD is about 100MB/s which I tested with a single 16.6GB movie file.Since I had one drive slot left (Disk 6), I used it to put an older 64TB SSD I had laying around and enabled it as SSD cache. No need to buy the expansion card. However when using only one SATA SSD, cache is limited to read operations. But as you can see from the attached image, the sustained writing speed of 110MB/s was entirely done on the 4TB HDD. CPU usage stayed fixed at 30% during the entire transfer. (The difference between individual disk write speed is just because it shows the instant write speed, not the mean write speed which usually was the same between Disks 1 to 5).Now I'm considering adding a second GbE port to my PC, since this NAS has 4 GbE port which support link aggregation.I'm extremely pleased with this purchase. Plus it has INTERNAL power transformer, so there is no extra bulky external brick whose power cable comes out easily when reaching behind the NAS as the older models I have.
