Memory for your NAS – Crucial RAM for your Synology and QNAP Guide

Choosing the Right Memory for your Synology and QNAP NAS

A network attached storage device, or NAS, is very similar to a regular desktop computer in so many ways. The Architecture of the NAS device in terms of hardware has not changed a great deal between the two, with both still featuring a motherboard, CPU, hard drives and, of course, memory. The memory, or RAM as it’s more commonly known, is the part of the NAS that is dedicated to handling random and incidental instances of data use. In real terms that means that it is the part of the computer that dictates how many programs or tasks or actions can be handled at any given time by the NAS system. Sure, the CPU dictates the power of the machine, but think of the memory as the extent to which (and the frequency of) the tasks can perform. All NAS devices arrive with a portion of memory includes, typically in the form of Gigabytes, and generally around 1-4GB to compliment the CPU and ensure smooth running for general use. But what about extensive use? Specialised use? tasks that require enhanced rendering (creation)not graphics or those that require many, many users to access the NAS at once? It is for reasons such as these that many users look at upgrading their NAS drive with more memory, often doubling, trebling or quadrupling the existing RAM inside to push performance.

Choosing the Right Compatible Memory for my NAS

Like most technology, NAS server devices can differ greatly from one to another and if you are looking to upgrade the RAM on your NAS, you should ensure you choose the right compatible memory for your NAS. important factors to consider:

DDR 1, 2, 3, 4 or 5?

As newer and better performing RAM has been developed, the physical build of memory has changed. Factors such as the efficiency of the chips on-board to the connectors themselves have changed. Always be sure to check that the memory you choose is the right DDR and DIMM for your NAS. Generally, all modern NAS use DDR3, DDR3L or DDR4 right now. Also, most Desktop NAS use SO-DIMM and rackmount use LONG-DIMM. Though this is by no means concrete and often there are exceptions to the rule. ALWAYS check first!

Memory Frequency

The MHz frequency band of the RAM dictates the speed of communication/package handling of data via the memory when in use. It is for this reason (among others) that RAM should always be in pairs (eg, 2 sticks of the same capacity/speed) or a single stick. So that these speeds are stable. Generally the lowest memory frequency you should look for us 1600mhz and ideally 1866mhz minimum if supported.

Memory Capacity

The capacity of memory, almost always dictated in gigabytes, is the amount of data available to handle tasks and applications actioned by the CPU at any given time. The more capacity you have, the greater the weight of tasks/apps/users you can handle. All actions and executed applications require memory space and are pretty much the main reason people upgrade the RAM on their NAS.
There are other factors such as Electronic Error Correction (ECC) memory that check/repair handled data to maintain integrity or passive cooling that improves speeds under heavy use, but these are especially Enterprise considerations for NAS and found in rackmount devices mostly.

Official Memory NAS upgrades Vs Crucial Memory

As you would expect, most NAS brands such as Synology or QNAP sell their own business official memory upgrades to their NAS drive devices. I, these official upgrades are much, much more expensive than crucial memory alternatives, even though they are often the EXACT SAME Memory! This could be due to packaging, manufacturer, specialised testing, or simply to make a quick buck! Also, many NAS brands sell their own branded NAS, but a quick look at their compatibility pages show they can still support crucial memory fine. The result is that in most cases, you can save a good chunk of money by buying crucial memory, rather than the Synology or QNAP official RAM. Just always be sure to check in advance on the NAS memory compatibility pages before you buy as brands can change their compatibility in later releases and we cannot be held accountable for that.

  1. Hello Rob,

    Great article on the supported RAM densities. I wanted to drop my insights to further help with the cause. I had purchased a Synology DS1819+ based on your recommendations a few months back. I decided to upgrade the unit to the maximum 32GB capacity it can handle. I went with 2x Crucial 16GB DDR4 2400 MHz SO-DIMM modules (CT16G4SFD824A).

    When unboxing the Synology DS1819+, I immediately took out the existing 4GB synology memory and popped in the 2x 16GB crucial sticks. I powered on the device for the first time and imported my settings from my existing Synology NAS DS418+ with no issues.

    I did receive a memory notification on the new DS1819+

    Memory configuration that is not compatible with this model is detected. We recommend that you refer to the specifications in the hardware installation guide or on the official website to correct the following memory configuration.
    1. Inserted incompatible memory modules

    The weird thing is that Info Center shows 32GB RAM capacity and everything is healthy. I have not had this message reappear or pestering me everyday about the Non-Synology branded RAM. It was only once that I got it and it was within the first hour of working with the new DS1819+.

    I’ve been running this setup for at least 2 months now with no issues, at least on the RAM side of things. I’ve been heavily using this NAS to sort out my pictures with Synology Moments. This application requires a lot of CPU and NVMe caching to do its deeds. But so far no interruptions or restarts from the NAS.
