Though both systems feature DDR4 memory, the DS920’s maximum 8GB of memory is beaten by the DS1522+ 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 (arriving with 8GB by default). NAS Model Installing a Synology NAS is easier than you can imagine. This article is a Synology DS1520+ overview. I will show you how to set up and install your NAS for the first time. Also, how to use its dedicated operating system DiskStation Manager (DSM) and perform basic configurations. Synology's NAS enclosures have stood out thanks to the robust software, DiskStation Manager (DSM). By offering a lightweight web-based OS with an exhaustive set of features, Synology was able to carve out a lead over its rivals. There are a few things about the DS1520+ that we don’t care for, and they’re mostly to do with bandwidth and throughput restrictions as we’ve mentioned already. Microsoft Edge is base on Chromium, so any issues you have with Chrome will most likely happen in Edge as well. You need to test on browses like Firefox that are not base on Chromium.

When you have the level of market dominance that Synology has in small business NAS, and you ignore how the market is moving, then trouble is undoubtedly on the horizon.Next up, let us discuss storage on the 5 drive DS1522+ and 4 drive DS920+, as these two systems are near enough identical on that one. Both arrive with SATA storage bays, though you can deploy either NAS with as little as a single drive if you want. From there you can go ahead and install enough drives to accommodate a RAID 1, RAID 5, RAID 6 or Synology’s own flexible RAID configuration, SHR. Both systems can be initialized to operate with either a BTRFS or EXT4 file system, as well as supporting the wide range of services and features of the Synology Storage Manager. Finally, as mentioned, both systems feature M.2 NVMe SSD bays and both only allow these to be used for caching with DSM and its services/storage. However, in terms of expandability, these systems have one key difference, with the DS920+ supporting a single expansion (allowing a maximum 9 bays of storage) whilst the DS1522+ supports two DX517 expansion chassis and reaches a total potential 15 bays of storage. As both systems support the latest version of Synology DSM, the maximum volume, simultaneous volumes, active storage shares and hybrid storage support are largely identical. Much like previous comparisons of the DS920+ and DS1520+ that were released a couple of months apart, the initial 1 drive bay difference between the 4-bay and the 5-bay isn’t a vast amount, but the scalability with those expansions makes much more of an impact (especially if you are looking at using caching with those NVMe Bays or want to scale up your network connectivity and want to ensure it gets saturated). Model 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. I personally have the DS 1520+. You sir have made the comparison between 1520+ and 1522+ in a previous video. This Next up, let us discuss storage on the DS1522+ and DS1520+M, as these two systems are near enough identical on that one. Both arrive with 5x SATA storage bays, though you can deploy either NAS with as little as a single rive if you want. From there you can go ahead and install enough drives to accommodate a RAID 1, RAID 5, RAID 6 or Synology’s own flexible RAID configuration, SHR. Both systems can be initialized to operate with either a BTRFS or EXT4 file system, as well as supporting the wide range of services and features of the Synology Storage Manager. Finally, as mentioned, both systems feature M.2 NVMe SSD bays and both only allow these to be used for caching with DSM and its services/storage. Even in terms of expandability, these systems are largely identical. with both supporting the connection of two DX517 expansion chassis and reaching a total potential 15 bays of storage. As both systems support the latest version of Synology DSM, that maximum volume, simultaneous volumes, active storage shares and hybrid storage support are largely identical. The only area where things might differ significantly between the DS1520+ and DS1522+ is regarding Hard Drive compatibility. Synology changed its position a bit on compatibility in a few of the 2022 series hardware releases (beginning with the RS3622xs+, DS3622xs+ and DS2422+ at the start of the year) with them stating that they fully support the use of their own HDDs and SSDs in these systems, but not in third party drives from the likes of WD and Seagate. These drives will still be usable in their systems, but the user will be greeted by a warning message regarding compatibility. Now, this is not a factor of the DS1520+ compatibility, however, we are still (at the time of writing) awaiting confirmation of the HDD compatibility list of the DS1522+ NAS, so although it is NOT CONFIRMED RIGHT NOW it is possible that your choice of supported HDDs might impact which NAS is better for your storage. Model

Where it is much harder to be critical is in respect of the Synology DSM platform, as this is easily the most mature NAS operating system around. At the time of writing the version on our review system was DSM 6.2.3-25426 Update 2, the initial release of DSM for this hardware. Another Synology hardware fail… at minimum it should have arrived with at least 2GBeE as standard. Synology always has been a hardware joke when compared to their competition.The first thing you need to do to get the NAS sorted out is to install the hard drives. For both Consumer and SMB Synology NAS, the HDD installation is almost the same. 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+. Why not better compare the 1522+ to the 1520+? They have the same number of possible drives and they both ship with 8GB of RAM. 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.
