To partly balance what appears to be a retrograde step, two NVMe slots have been added to provide high speed caching of the drives. If you are migrating and upgrading, I'd be sure to read the section on HDD Migration and look closely at the table, considering your Source and Destination NAS models. Though both systems feature 8GB of DDR4 memory, the 1522+ has much higher pedigree and wins here thanks to its use of much more impressive ECC (error code correction) memory to identify and repair any bit level write errors and can also be scaled to a considerably higher 32GB of memory (with the DS1520+ maxing out at 8GB). NAS Model On the taskbar, you have the Main Menu on the left side; and on the right, you have Notifications, Options, Search, and Widgets. On the desktop area, you get app shortcuts and all widgets you decide to add. Two widgets are immediately displayed: System Health and Resource Monitor. 7. Manage your Synology Storage Space

Synology DiskStation DS1520+ is an ideal network-attached storage solution suitable for small office and IT enthusiasts. Two built-in M.2 SSD slots and Synology SSD Cache technology allow you to boost system I/O and application performance. The scalable storage design of DS1520+ lets you start small and expand storage capacity with Synology DX517 as your data grows. 1.1. NAS Features

Business NAS solution with expansion in mind

And, looking at that old hardware made us wonder why the new DS1520+ isn’t as good as the model it theoretically replaces, in several important respects. Synology DS1520+ arrives with the full 8GB of memory available on day one, which will be especially useful to those looking at Virtual Machine deployment and surveillance utilisation. Much like the Synology DS920+, the Synology DS1520+ features 4GB of soldered DDR4 memory on the main controller board and an additional SODIMM slot, which in the case of the DS1520+, is populated by an official Synology 4GB memory module. Arriving with higher frequency memory than the DS1019+ and DDR3L memory before it, the DS1520+ will utilise fewer system resources to get the average task done, as well as being able to do more active tasks overall too. So, when comparing the DS1520+ and the DS1019+ directly in terms of internal performance, there really is no competition, with the newer gen box winning by a landslide. This is especially true both if you are utilising the twin internal NVMe SSD caching bays to further bolster your internal performance, as well as if you are attaching more drives with those expansion options. It is also worth noting that the E10M20-T1 card that upgraded the DS1517+ to 10GbE also gave it two NVMe slots, matching the DS1520+. The 4 and 5-Bay Diskstation releases from Synology have always been one of the most interesting tiers of the brand’s desktop solutions. The reason for this is that all too often this scale of system serves as a bridging point between Prosumer & SOHO systems and the small/medium business hardware in their portfolio. This is demonstrated first in the scale of the available RAID 5/6 storage, but then more so in the scalability and upgradability of these two volumes system, allowing one to two expansions, greater network connectivity (arriving with 2x or 4x LAN ports) and better internal hardware than the more domestic targetted solutions – often with the internal hardware differing considerably between each periodic 2-3yr refresh by the brand. Let’s first look at the internal hardware of these two NAS’ to see how much they differ. The DS920+ NAS first arrived on the scene with some great hardware advantages over the rest of the plus series 2020 systems (DS720+, DS420+, etc), arriving with a 4 Core Intel Celeron Processor that featured integrated graphics, 4GB of DDR4 2666Mhz memory and NVMe SSD upgrade slots. In the two years since its release though, Synology clearly decided to make some big changes in the base level architecture of the plus series and specifically in the DS1522+ to make it considerably more scalable and general business/file-ops focused. The newer DS1522+ features a dual-core AMD Ryzen embedded R1600 that, although arriving with half the cores of the Celeron in the DS920+, has a higher CPU frequency and total achievable frequency in turbo/burst when needed. That said, users will be surprised to learn that this CPU also does not feature embedded graphics, so therefore the DS1522+ will be less CPU efficient at handling multimedia or VM deployment than the DS920+.

A faster method, the one I will use for this guide, is to enter your NAS's name directly in the windows file explorer. My NAS's name is NAS_mulcas; then I should use the following format: \\NAS_mulcas. The same name as the one point in the image above. The installation will take 10min approx. The NAS will restart automatically right after the DSM installation. You will hear a short beep when it's done. Synology Chat – Aimed at businesses, Synology Chat is an IM service that transforms the way users collaborate and communicate.The hardware on offer with the DS1520+ makes it an outstanding choice as a Plex media server. It can transcode several 4K files at once, and eSATA extensibility means you won't have to worry about running out of storage. Synology will establish the connection for you, no need to worry about any additional configuration. 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. Synology had some popular NAS released last year, among those, the DiskStation DS1520+. This NAS is one of the most proficient and powerful network storage devices for home and small business users currently in the market. This system is specially designed for various purposes, allowing you to perform demanding and straightforward tasks, possible to its powerful hardware and the web-based Synology DiskStation Manager (DSM). Even when using link aggregation the best throughput that four 1GbE adapters are capable is about 450Mb/s, where a single 10GbE port can do double that performance easily.

Finally, on the button, you get two NVMe slots for Read / Write Cache. 4. DS1520+ Hardware Installation Suppose you're using the NAS for the first time; you need to create a volume to store all your files and precious data. First, I will create one storage pool using Synology Hybrid Raid (SHR), then a volume, and finally, a shared folder. As this system supports SATA drive media, that means it supports up to the very latest 16TB NAS hard drives, as well as the soon to arrive 18TB and 20TB hard drives thanks to heat-assisted magnetic recording (HAMR) technology towards the end of 2020. That means that the DS1520+ and it’s 5 storage bays provide a staggering amount of storage potential, even in RAID 5 and RAID 6 configs. Alongside the traditional RAID configurations you would expect in a 5 drive NAS system, the DS1520+ also support Synology Hybrid RAID (SHR) which allows a more gradual and scaled storage plan, as well as allowing you to utilise drives of different capacities in a single RAID configuration without losing storage overall. SHR is often one of the key reasons that people buy a Synology NAS system after the DSM software. Returning to our comparison of old and new, they both sport two USB 3.0, two eSATA, four 1GbE LAN ports and have five internal bays that can take 3.5 or 2.5-inch hard drives or SSDs. The 5-Bay Diskstation releases from Synology have always been one of the most interesting tiers of the brand’s desktop solutions. The reason for this is that all too often this scale of system serves as a bridging point between Prosumer & SOHO systems and the small/medium business hardware in their portfolio. This is demonstrated first in the scale of the available RAID 5/6 storage, but then more so in the scalability and upgradability of the 5-Bay system, allowing two expansions, greater network connectivity and better internal hardware than the more domestic targetted solutions – often with the internal hardware differing considerably between each periodic 2-3yr refresh by the brand. Let’s first look at the internal hardware of these two NAS’ to see how much they differ. The DS1520+ NAS first arrived on the scene with some great hardware advantages over the (then 2 months sooner released) DS920+, arriving with a 4 Core Intel Celeron Processor that featured integrated graphics, 8GB of DDR4 2666Mhz memory and NVMe SSD upgrade slots. In the two years since its release though, Synology clearly decided to make some big changes in the DS1522+ to make it considerably more scalable and general business/file-ops focused. The newer DS1522+ features a dual-core AMD Ryzen embedded R1600 that, although arriving with half the cores of the Celeron in the DS1520+, has a higher CPU frequency and total achievable frequency in turbo/burst when needed. That said, users will be surprised to learn that this CPU also does not feature embedded graphics, so therefore the DS1522+ will be less CPU efficient at handling multimedia or VM deployment than the DS1520+.Synology Surveillance Station – Safeguard your business, home, and other valuable assets with reliable video surveillance tools. However, the DS1517+ also has a PCIe slot, allowing it to accept a 10GbE LAN adapter increasing its network throughput by from 4Gbps to 14Gbps if all ports are utilised. Unlike Qnap when you buy your hardware, you arent forced to pay for syncing from and to your own hardware. You can also access the shared folder and its data from the File Station app. 7.4. Access the Shared Folder Within the Local Network For the DS1520+, pull the drive trays out, then the (two) fastening panels from the tray's sides. Install the drives into the drive tray and insert the fastening panels to secure the drive in place. I am using 3.5-inch HDDs, so that will do for me. But if you are using 2.5-inch HDDs, you need to use the 2.5-inch HDD screws to secure the drives.
