About this deal

In 2018, Synology added M.2 slots to select Plus servers to host two NVMe solid-state drives (SSDs) for caching to increase the performance of certain types of applications. Since 2020, virtually all four-bay or larger Plus servers have had this feature. Synology NAS 10GbE upgrade options: PCIe add-on card ( DS1621+) or Easy Network upgrade module ( DS923+). Synology server upgrade: 10Gbps network As for which drives to get, it's generally best to use those on the compatibility list, which changes from one server to another. While Synology has made drive support more and more strict, this is the way to go if you have a server for serious business usage. Alternatively, with servers sans M.2 slots, you can use regular 2.5-inch SSDs installed in the server's drive bays for caching stead of a storage volume.

This NAS model is sold with 4GB RAM preinstalled. So official upgrade option is 4+4 = 8GB. Unofficially it can be also 4+4=8GB or 4+8=12GB or 8+8=16GB.It's worth noting that you don't have to use all of a server's drive bays and can add more drives to the empty bays at any time. Each Synology server model comes with a specific CPU, and you can't change that -- most of the time, the CPU is soldered on the motherboard. Generally, populate a server with the storage ( HDDs vs SSDs), and you're ready. All servers come with one or more Gigabit ports that are fast enough for a typical home or office network. The Synology DS620Slim is a very compact and versatile NAS. It offers the latest features by mean of the DSM (built-in Desktop Manager) and power consumption is pretty low. especially when used in conjunction with SSD disk instead of the mechanical ones. A very good advantage together with the reduced noise levels from HDD drives.

In the Plus family, most servers of model years 2018 and newer have either of the two options. Specifically, for now, you can expect the following:With 4K average latency, the DS620slim showed similar results as iSCSI posted 12.483ms read and 23.92ms write vs. CIFS’s 31.139ms read and 24.193ms write.

What's more, it's the first slim sever to have Synology's Virtual Machine Manager. VMM is a powerful app that allows the server to run multiple virtual machines -- be it a Windows, Linux, or another DSM system -- on the inside. With this capability, the server has endless potential in what you can do with it. Before the DS620slim, I've used all slim servers from Synology, from the DS409slim to the DS419slim. They all have one big issue: Too little RAM, fixed at 256MB or 512MB, and a modest amount of storage space due to the nature of 2.5-inch drives. So, slim servers have generally been considered "toys," suiting only those with basic needs. Like the RAM slots, the M.2 slots are generally easily accessible. Most are on the inside wall or underside of the server, making the upgrade straightforward. Just pop the NVMe SSDs onto the slots and use the server's Storage Manager to handle the caching. NVMe SSD as storage spaceDigital storage and management manufacturer Synology recently announced a new 6-bay Network Attached Storage enclosure in its Slim range that is designed to be compact and lightweight while still offering good performance. The DS620Slim accepts 2.5" SSD or HDD media – with its six bays filled with 5TB drives it can provide a total of 30TB of storage. These servers handle storage expansion via the eSATA port, which has a ceiling speed of 5Gbps. And that's the link between the server and all the internal drives hosted by the expansion box. And that means two things:

If you have a router or switch supporting Link Aggregation, you can turn a server's two Gigabit LAN ports into a 2Gbps connection to increase the bandwidth.Running DSM 6.2, the Synology DS620slim has the same hardware specs as the DS218+ and can run all high-end apps never before available to the slim series. Synology DS620slim: Storage and memory anxieties no more But the one thing you do have to watch for on older units is the danger of upgrades that attempt to make the units obsolete. Synology was bad about this with DSM7, making it a requirement on newly installed older units like my DS213j (there are workarounds). DSM7 requires a lot more resources than DSM6 and you can immediately tell the bloat when you use the two versions on the same hardware. Keeping older units ‘period correct’ on their older versions and using them within their limitations keeps you out of trouble. Used or new: Older models have excellent values. It's safe to get an old server that supports the latest version of DSM, which is generally true for all servers released in the past eight years.
