It’s important to know that although there are many different kinds of Synology NAS, this guide is for the DS1821+ NAS. Although many of the Diskstation range are similar, there are many differences in Memory module frequency, size and capacity support between the hardware architecture of devices, so make sure you are only following this guide if you want to upgrade the memory unofficially on a Synology DS1821+ NAS drive. For standard deviation, the WD Gold recorded 611.48ms read and 333.9ms write in SMB, and 51.12ms read and 165.22ms write in iSCSI. The more is always, the better in terms of capacity, but generally, you won't need drives larger than 250GB for caching. This next section will determine how much of the volume you’d like to allocate. Generally, most people will use all of it, so you can select Max.If you’d like to use something smaller, you can enter the value. The DS1821+ is Synology's second Plus series after the DS1621+ to adopt the powerful quad-core AMD Ryzen TM processor. The new processor delivers over double the computing power over its predecessor 1, offering significantly faster performance and snappier response time across Synology Drive, Moments, and more.

The storage analyzer allows you to see what files/folders are taking up space on your NAS and if any duplicates exist. It’s a powerful tool that periodically comes in handy. Moving on to the max latency, the WD Gold hit 2,453.2ms read and 3,779.2ms write in SMB, while the reaching 1,461.1ms read and 846.9ms write in iSCSI. While this certainly makes them a perfect fit for enterprise-level data centers, they are also a great choice for SMBs that need to store huge amounts of data and for those who want to future-proof their repository (capacity-wise). So, it made sense for us to see what it is capable of outputting using some of the leading desktop (or SMB) NAS form factors. This might not seem important on the surface, but understanding how your storage is being used is integral! 2.5 Uninterruptible Power Supply (UPS) Our next test shifts focus from a pure 8K sequential 100% read/write scenario to a mixed 8K 70/30 workload, which will demonstrate how performance scales in a setting from 2T/2Q up to 16T/16Q.Next we need to access the memory bays of the Synology DS1821+ NAS. These are located at the base of the device and require you to unscrew two Phillips head screws, then removing the metal panel. Certain restrictions apply when adding drives to existing storage pools. Refer to this article for more information.

Here is a link to my favorite UPS (that I own). If you’d like to buy a UPS but spend a little less, here is another great option which has USB data transfer as well so it can automatically turn off your NAS! Here are some other Synology NAS UPS options.

In our first test, which measures throughput, the WD Gold 22TB had a range of 354 IOPS to 412 IOPS in SMB and 526 IOPS to 1,700 IOPS in iSCSI. When the drive is unmounted, no one can access the files until you mount the folder again. If you lose the encryption key, your files will be lost forever. Keep it somewhere safe! With that, let's proceed with the upgrade. For this post, I did the upgrades on a DS1821+, but the processes and parts are the same on a DS1621+. Synology DS1821+: RAM upgrade In any case, installing the SSDs onto the server is super easy. The two M.2 slots are inside the server's left wall. Take the first and second drive bays out, and you can reach them. Synology DS1821+: 10Gbps NIC card upgrade Select the Hard Drives (generally all of them) that you’d like in this Storage Pool and select Next.

If you're mulling over the two, that is the only point you should consider. Synology DS1821+ vs DS1621+: Hardware specifications Model

Oprettelse af M.2-lagerpulje understøttes kun på SSD'er, der er verificeret af Synology, og som har været igennem omfattende test under ekstreme temperaturforhold. De termiske parametre for SSD'er og NAS-systemet er blevet finjusteret for at sikre, at den termiske tilstand håndteres korrekt i et I/O-intensivt miljø. ( Få mere at vide) During the memory test, your Synology NAS will be rebooted. It will recover after another reboot if its memory is normal and passes the test. However, if the memory test fails to finish or shows that there is an error, the memory may be faulty. In this case, you are strongly recommended to return your Synology NAS for repair. Just in case you have installed a non-Synology memory module, please remove it and rerun the memory test. Though once again you should remember that Synology do not recommend using memory modules that are not from Synology themselves, so this test may not be indicative of the health of unofficial memory in your Synology NAS. Alternatively, you can perform as many actions and processes as possible (scans, copy/pastes, thumbnail generation, transcode a 4K file, RAID changes, synchronisation, etc) at once to see how the task manager and resource monitor behaves in the Synology DS1821+. It should spike each time and at a greater height as you do more and more and once it exceeds the memory you had previously installed, this is a good confirmation that the installation is working fine. Next, we need to access and remove the existing memory, as the news 32GB or 64GB of memory for our Synology DS1821+ will occupy both slots.

While we went through the initial Synology NAS setup process, there are many additional items you can use your NAS for. I have a bunch of tutorials that I will link below showing how to complete certain actions. Keep in mind, there are a ton of apps you can install and these are my favorite Synology NAS apps that you can install! 4.1 Accessing your Synology NAS Outside of Your Local NetworkThe easiest way to think of snapshots is that they “freeze” your files in time and allow you to recover those files later if necessary. Enable UPS support and select the UPS type that you own. You can then configure the time before your NAS enters safe mode. 2.6 How to Setup Notifications on a Synology NAS Synologys M.2 NVME SSD-diske i SNV3400-serien kan installeres via de indbyggede M.2-stik for at aktivere SSD-cachelagring eller oprette SSD-lagerpuljer. Diske sælges separat. DSM will install and reboot when finished. After a few minutes have passed, open a new tab and navigate to http://find.synology.com. Your DiskStation should show up and you will be able to connect.
