cache

Hi everyone, I recently got a couple of Intel Optane M10 16gb nvme drives, as I would like to get my dockers moved to them so I can then spin down the HDDs. The weird issue I am seeing is that, whenever I try to add the storage pool ( either via the interface or the script ) , the maximum size...

Hi all, Is it possible to have an nvme pool and an nvme read cache at the same time? I have one single nvme pool already and one nvme chip over for no use. I don’t expect any major speed increase but just have some use of the second chip. I have an ds423+. Regards Roger

A while ago I discovered PhotoPrism and started with it on an older Synology DS916+. While it worked, the performance wasn’t quite what I hoped for, especially with AI and larger libraries. After some searching on the local second-hand market (Willhaben), I found a great deal on a DS1621+ with...

Topic says it all more or less. Is it possible to have a r/w NVMe cache on the DS923+ even if the brand and size of the NVME's differ? EDIT: Found answer. Yes it seems possible. Found no way to delete this thread though...

Installed a couple of Arch Memory 512GB M.2 NVME drives for my DS1621+. Thought creating a cache would be pretty straightforward, but I'm finding Synology terminology confusing. The DS1621+ has five 20TB drives, configured as separate btrfs volumes (i.e. not SHR/RAID). I'd like to create a read...

I don't know why but I ran the SSD advisor on my 918+ and it says get a 700 GB cache. Shall I? Will I feel a difference?

Hi all I am looking for add Cache to my 1520+ There is some Recommend Brands? or muddles? Thanks

Since I added the non supported SSD in the non supported eSATA external enclosure on all 3 NAS’s: 2x 720+ and 1x 718+. At the time of install I did an extended smart test on it, on each, and all passed. They all had ram upgrades, Synology or “Other”, up to a total of 10GB, NVME R/W cache’s where...

Topic says it all. My DS923+ runs all SSD's at the moment, is there a point of using my old NVMe as cache?

I bought two WDS100T3X0C-00SJG0 (Western Digital WD BLACK SN750 NVMe M.2 2280 1TB) and placed them into the NVMe slots and setup write cache in RAID1. I don't know when this started happening, but one day of my two NVMe's went missing after a reboot. I setup read cache on the single drive and...

I took advantage of Black Friday sales and just ordered a DS923+ that I will use for file storage and backup purposes. For my use, my concern is maximizing transfer speeds and I just read that on Reddit: « System RAM also caches I/O, so the SSD cache will only give you a boost if your...

So the point of this thread is to start a list of known to work well SSDs on Synology. I dont care if they are 'blessed' or not blessed by Synoloyg, the only thing that matters is that actual users get good performance from them. And Synology branded drives are ridiculous poop, way too small and...

Hello all, Would like to ask if SSD cache could give performance improve in a volume dedicated to store and serve large VM files by NFS. I've read that only certain kinds of data can be cached and VM HDDs are used as block devices where DSM doesn't understand the contents of. I've also seen a...

Setting up new HDD NAS on DSM 7, and looking at best options for NVMe caching. Figured I could run Cache Advisor on old NAS running DSM 6.2, see what my historic usage pattern indicates, but I am not seeing any Cache Advisor button under Storage Manager on my old NAS. The help files on that...

We know by now that only Synology NVMe's work for storage pool, but it seems many are using other brands for read cache, with few if any issues. Is this correct? Any word on maximum capacity the 923+ can handle? It doesn't appear to be listed in the specifications. I'm looking at 2 TB NVMe's...

This am I woke up to a volume warning There was no other warning other than me checking. Seems my 1tb SSD cache 1 bit the dust after 2 years. Disk 2 is still good, but I disabled it also and probably won't replace 1. Any opinions? TIA

Hello there guys as title says I use an 4TB WD Red as cache for my NAS. Today I got an error that cache at volumme 1 had crashed and some other things and I shut down the machine, removed SSD and insert it again. I see this message you see here : SSD guess is working fine now and I need...

Hello everything is fine ? This is the second time that I have had problems with this SLOT SSD, previously the same problem occurred, so I sent the SSD for warranty, they sent me an identical but new model, I installed this new SSD in SLOT 2 in January but the problem occurred again with less...

DS916+ with three 8tb Red WD drives and one 512gig Samsung SSD cache drive. One of the drives has a System Partition Failed (but healthy) and another Crashed (but healthy). Repair link brings up the dreaded : "Install more drives: Insufficient number of available drives for repair...." So I...

This is just an info type question. My DS920 X4 16tb drives. It is used to backup for 5 PCs and to date 16 cellphones. my nas has 8g of ram and 2 1tb NVMe's set to R/W. I tried setting the cache to write only and didn't notice any difference. Just wonder what anyone opinion of which is better...
