What is the benefit of SSD cache Synology?

Purpose. SSD cache, also known as flash caching, is a cost-effective way to improve the performance of HDD arrays by storing the most frequently accessed data on SSDs.

What is the benefit of SSD cache in NAS?

To put it simply, SSD caching improves the performance of your NAS by placing frequently accessed files onto a solid-state drive rather than a traditional hard drive. Since modern NAS systems can be configured to automatically 'learn' which files are accessed most often and cache them on the SSD.

Should I enable cache on SSD?

There are many benefits to enabling SSD caching on your Windows 10 or 11 computer. Perhaps the most obvious benefit is that it can speed up your computer's overall performance. This is because access to data stored on an SSD is generally much faster than access to data stored on a traditional hard drive.

Do I need SSD cache Synology?

If you use your Synology NAS as an FTP server, for Web Hosting, intensive File Sharing, or you run VMs on your NAS, or your NAS acts as a Virtual Machine storage, or anything that requires continual and systematic retrieval of data, you will benefit extensively from using the M. 2 NVMe SSD Cache.

Is more or less cache better for SSD?

In these scenarios, SSD Cache can greatly improve overall read performance. For example, a system with SSD cache can deliver a 2.5 times better IOPS performance compared to the same system without SSD Cache in the case of OLTP workload and latency is also reduced.

NAS SSD Cache and Caching Benefits - Before You Buy

How much SSD cache do you need for NAS?

We recommend setting the minimum size of an SSD cache to at least 2.5% of the volume size.

How does SSD cache work on Synology NAS?

A read-only cache uses one or more SSDs to store frequently read data and accelerate the random read performance. No data loss will occur in the event of SSD failure because this cache mode only stores copies of data from the volume. A read-write cache uses at least two SSDs to create a fault-tolerant cache.

How long do SSD last for NAS?

On average, SSDs last for around 3 to 5 years, but some can last up to 10 years or more. However, this can vary based on how the SSD is used. To make sure your SSD lasts as long as possible, it's best to use a SSD that is made for NAS use and to avoid doing things on the NAS that involve a lot of data writing.

How do I keep my SSD healthy?

Why do NAS not use SSD?

While solid-state storage may offer maximum performance, this isn't necessarily in the context of adding them to NAS drives. SSD drives don't tend to offer a big advantage, especially when you take into consideration that gigabit Ethernet connections are only able to reach transfer speeds of up to 110MB/sec.

Should I leave my NAS on all the time?

Your files are stored on the NAS server and can be synchronized, or automatically kept up-to-date, on all of your devices. This service needs to always be online so the NAS should always be on. If you are using your NAS for web hosting like I am, you need to keep it online 24/7.

What is the maximum size of Synology SSD cache?

Every 1 GB of SSD cache requires approximately 416 KB of system memory (expandable memory can be counted), and the maximum cache size is 930 GB.

Can I remove SSD cache Synology?

Go to Storage Manager > SSD Cache and select the SSD cache to remove. Click Remove to permanently remove the SSD cache. Power off your Synology NAS. Physically remove the SSDs from your Synology NAS and replace them with ones of a larger capacity.

Can I remove SSD cache from Synology NAS?

To remove an SSD cache:

Always remove the SSD cache via Storage Manager before unplugging its SSDs from Synology NAS. Go to the Storage page. Click the upper-right icon of the SSD cache you want to remove. Select Remove.

Can a NAS be as fast as an SSD?

But as you can see, at these speeds, you can have a NAS that is basically as fast as an NVMe SSD in terms of throughput. Due to the latency though, running intense I/O applications is still not going to be as fast as an internally installed drive.

How much RAM is recommended for NAS?

For basic use, 4GB or 8GB will suffice. If you have a business Synology NAS, we would recommend at least 16GB. If more people open and save their work on the NAS at the same time, this is very demanding for the RAM. Keep in mind that not all RAM modules are suitable for your Synology NAS.

Do I need to defrag my Synology?

Why is defragmentation important for my Synology NAS? Every NAS suffers from a constant growth of fragmentation. If you don't clean up, your NAS performance is ultimately impacted. Defragging helps speed up your Synology NAS hard disks.

What is the difference between Synology read and read write cache?

The feature is presented as two options: read-only and read-write. While the read-only cache contains just copies of data from the native Synology volume, the read-write one stores new data that hasn't been written back to the hard drives yet.

How do I clean up my Synology NAS?

How do I change my SSD cache Synology?

Go to Synology High Availability > Storage. Select the volume where the SSD cache is mounted. Click Repair.

How do I recreate my Synology SSD cache?

After the SSD cache has been removed, go back to Storage Manager > Storage. Click Create > Create SSD Cache to add a new SSD cache. Select your preferred cache type and follow the wizard process.

How do I know if my SSD has DRAM cache?

Most manufacturers do not outright mention if a particular model has DRAM or not. Sadly, no software can detect the presence of DRAM Cache either, not at the time of writing this article anyway.

How long will a Synology NAS last?

My recommendation is to change your NAS every 5 YEARS. Most NAS devices have a 3-year warranty.

Is NAS good for long term storage?

Invest in Synology NAS and benefit from the huge storage potential, full data privacy, and fast local file transfer speeds of your own private cloud.
