On the approved list for the DS1522+ are, unsurprisingly, the Synology HAT and SAT drives, along with the N300 by Toshiba, IronWolf and SkyHawk by Seagate, WD Red+ and Purple.
Creating M.2 storage pools requires the use of Synology-verified SSDs, which are rigorously tested under extreme temperature conditions. Thermal parameters for SSDs and NAS units are fine-tuned to ensure optimal management of thermal conditions under I/O-intensive environments. ( Learn more) Unless that user has a 10GbE, 5GbE or 2.5GbE network port, and the DS1522+ has the E10G22-T1-Mini fitted, they’ll get around 113MB/s reading or writing to the NAS. Performance Synology Virtual Machine Manager (VMM): An intuitive hypervisor that supports Windows, Linux, and Virtual DSM virtual machines. Its powerful disaster recovery tools help users achieve maximum service uptime. But for the most part, the new server has a lot to offer. So much that I'm not going to touch everything it can do in this review. That'd take too long. Adding this functionality opens up a lot of benefits for users. Creative professionals will be able to edit large video and image files directly from the NAS, while businesses will be able to allow numerous employees to simultaneously access larger files hosted on the DS1522+. Home users who want to maximize their storage speed or build a highly-efficient media streaming system will also benefit greatly from using a 10GbE infrastructure. Synology DiskStation DS1522+ Performance Review ConfigurationThe biggest upgrade over previous generations is the addition of 10GbE connectivity, although the path Synology took on the 15-series model over the years has somewhat limited certain features. Our Enterprise Synthetic Workload Analysis includes four profiles based on real-world tasks. These profiles have been developed to make it easier to compare to our past benchmarks as well as widely-published values such as max 4k read and write speed and 8k 70/30, which is commonly used for enterprise drives. Not to use actively… Just to replace the many DOA units that died over the years, so they could access old cases and re-save the data on cheap USB drives (2x drives for “redundency”). All that, just to ensure the data can be retrieved / produced in the future.
Moving on to standard deviation results, the DS1522+ posted 24.95ms to 658.1ms in SMB and 16ms to 338.23ms in iSCSI for our HDD configuration. When cache was enabled, the DiskStation showed 6.23ms to 72.96ms (SMB) and 32.62ms to 398.31ms (iSCSI). Don’t misunderstand, the DS1522+ is an excellent NAS, but it could have been amazing if Synology would shelve some of its technology dogma. Looking at average latency with our HDD configuration, SMB showed a burst speed of 18.24ms and finished at 1,176.67ms, while iSCSI recorded 8.98ms at burst and finished up at 175.42ms. With cache enabled, SMB ranged from 2.59ms to 439.6ms while iSCSI showed 0.36ms to 4.55ms. In my experience, AMD Ryzen is much more powerful for daily computing than Intel Atom or Celeron CPUs, which were widely used in previous models. The new AMD CPUs elevate these home and SMB servers' capability, making them more comparable to Synology's enterprise models running Intel Xeon chips.
The first 22 series desktop NAS from Synology brings some welcome changes
It's worth noting that the new 10Gbps module is proprietary and will only work on supported Synology servers. However, going strict on hardware support has been the Synology way. The clearest sign is DSM 7 where third-party USB dongles are no longer supported. While this approach increases the cost, it improves stability. The Drobo is still working ok, but it’s really slow and has long been discontinued, so it makes sense to proactively upgrade. We didn’t do a complete test of all the drive combinations and various network aggregation profiles, but the DS1522+ is an excellent performer and rarely appears to push either its CPU performance or memory use to the very limits.
Surveillance Station includes 2 free licenses. Connecting more cameras and devices requires additional licenses. Learn more I used a large file (some 100GB) for the tests and copied it between the server and a computer equipped with a 10Gbps network card and the fastest PCIe Gen 4 NVMe SSD. I used no NVMe caching for the tests. The Synology DiskStation DS1522+'s performance Per the NAS maker's naming convention, the DS15xx+ is the Plus 5-bay lineup for homes and SMBs that can house up to 15 drives. Five on its own and another ten via two expansion units. The server still features now-legacy eSATA ports to host expansion units instead of the latest and much faster Mini-SAS HD, like the case of the higher-end DS2422+.For those wanting the best connection speed to a single host system, the only choice is to get the E10G22-T1-Mini and a PCIe adapter to connect the two. You can also use the four 1GbE lines to connect the rest of the network to the NAS and aggregate them if you have a suitable switch. However, the more interesting Synology NAS that supports the E10G22-T1-Mini adapter is the DS1522+ NAS. This si a 5-Bay desktop solution that already arrives with 4x 1GbE LAN ports and the option to expand the total storage to a total 15x bays (using 2x DX517 adapters). With THAT level of storage available, as well as 4 network ports and upgradability of upto 32GB of memory, you can see why adding 10GbE to this system in its lifespan would make ALOT of sense. There is still the argument that some users would rather see 2.5GbE arriving on these devices, but we have still yet to see the rest of the 2022/2023 series be revealed. Usable capacity for each volume will be lower than the maximum volume size and is dependent on the filesystem and the amount of system metadata stored. For our testing, we configured the Synology DiskStation DS1522+ in RAID6 using five 16TB Synology HDDs. We also leveraged two Synology SNV3400 M.2 SSDs for testing with read and write cache enabled. Enterprise Synthetic Workload Analysis
Synology Drive: Host your own private cloud behind the safety of your NAS with 100% data ownership and no subscription fees. If you use 2.5-inch hard drives or SSDs, a screwdriver is needed. In this case, the included bag of little screws will come in handy. The biggest upgrade to the new DiskStation is support for 10GbE connectivity through an add-on card. This is a fairly big deal, as the DS1520+ was missing this functionality (i.e., Synology decided to remove the open PCIe slot used for 10GbE cards), which left users with only four 1GbE ports to transfer data.Synology Audio Station: Manage your music collection, create personal playlists, stream them to your own devices, or share them with family or friends. Sadly, the DS1522+ is strong evidence that Synology refuses to accept where this market is already going, and the sort of NAS customers want to buy now and in the future.
