NEW DSM7.0 SSD CACHE

This video goes over what's new in Synology's DSM7.0 SSD Cache, which is a huge upgrade over the old method! With DSM 7 the SSD cache is not only more stable, faster, but it also does not take your entire pool offline when you set it up!

真不错，为了看你的视频我去学英语。alsome videos you made! I learn English because of u

The way you could have tested it is real-world application tests. Using, say, Synology Universal Search and than searching for a bunch of files on largely populated disk, in order to see if search times are getting better as index is getting cached. Secondly, you could have VMs, and then measure if the (OS) boot time improves if you boot them multiple times as the whole VM disk image would get cached. I think the latter could have easily stand out if cache is really efficient. Just a few ideas...

Configure a read/write cache.

When the benchmark executes the writes should hit the cache. Whether they stay hot in cache after they flush to disk, and can be read back from is another question. It will depend on how specifically the cache mechanism is implemented in DSM 7.

How do you think this would go with say a NAS based photo library of Raw files, connected to a macbook that's editing the photos in lightroom, constantly going back and forth between the photos again and again. Are the file sizes too large to benefit from the cache?

[premiumbitter]

Do I need to use an SSD built for NAS/Enterprise (eg Seagate IronWolf 510), or can I use a consumer SSD?

I have two 2TB SSD Cache Cards installed, and it only allowed me to bring one online. When I tried configuring the second one, a box came up that said "The volume is already mounted with an SSD cache".

[Shanti]

Will DSM 7 support SATA SSDs also or just M.2 SSDs?

[tdragon]

Maybe try copying over a large folder with tons of small files. Like a wordpress installation with tons of plugins.

Does having 1 ssd drive on a ds920+ help at all on a 1gbps network or not really? Thank you for any response!

Would be great if we could chose which folders to cache. In my case I would like Synology drive to be used in my SSD cache but it sometimes chooses some movies and stuff which don’t need the speed at all

[notreallyme]

So if I’m using 1 gigabit Ethernet (home use, with 2 users) it sounds like using an NVME cache wouldn’t help, right? Would using WD Red drives with onboard cache be good enough?

Could you possibly make a video with same setup with ssd set for read and write cache? I'd really like to see that

[neumi]

It's quite disappointing that you can set a SSD cache only for one volume, even if you have 2 SSDs installed or leave space empty on the SSDs. So choose wisely, what you want to cache.

the question is: can i install DSM on 2.5 ssd? and then use hdd for storage?

[AussieTimeSirStewietheKnight]

You are at the limit of the 1gig connection until you go to 2.5gb or 10gb cache drives will not help that NAS you are testing with. What will help is a ton of small files or seek times to find files. Disk benchmark apps usally don’t test multi small file transfers. If you can get multi 1gig connection cache drives will help that. Create a LACP with 2 nicks can improve your test but only when you benchmark with 2 computers. Not sure of your nas supports multichannel SMB but that could help I know on Qnap this helps.

DSM 7 disabled SSD caching for sequential reads which makes it impossible to saturate a 10gbe for single user. Extremely annoying for video editing.

[leogaming]

i put 2 500GB m.2 ssd but now the cache is using like 8gb of ram and only leaving like 1gb of free ram. does anybody have any idea ??

[FreestylerAlbert]

still no support for SSD cache for multiple volumes?

[johnday]

Too much blah blah at the beginning...
