    Ssd caching installation

    Hi, I just bought 2 ssds that I want to use for caching. How do I install them on an Nas that is already up and running. If I shut down the nas and pull out 2-3 drives to access the ssd slots wont I ruin the storage pool created already? /Dennis

    ssd cache

    On rebuilding my DS920+. I'm wondering if it's worth activating the 1tb SSD cache. It was in my old system that crashed but never noticed a difference. Should I activate it or just ignore it. I've read here and on other forums that it doesn't make much difference and uses some system ram when...

    Does m.2 2280 nvme ssd make sense?

    Hi guys, I've just purchased a new nas (ds1821+) and I'm guessing if bye or not the m.2 2280 nvme ssd. What are the advantages? Being a professional photographer I use the nas as the archive for all of my pictures. Does the expense make sense? What is the suggested size/brand? Thanks!

    Would SSD benefit my photo workflow 1621+/10gbe?

    Hi people, first of all: thank you if you are helping me out! I've got a ds1621+ hooked up via 10gbe on my iMac via a thunderbolt adapter. Running speed tests to my nas with Black Magic I have 500+ write and about 1000 read. So far so good! But, and that is the strange thing. Coming home from...

    Oh, No... DSM 7.1 *REMOVED* critical SSD/NVME Cache Functionality!!! :-(

    DSM 6.2 through 6.2.4 Flash-Cache (SSD/NVME) worked great. DSM 7.01 removed only one key feature. DSM 7.1 now works entirely differently, removing many key features while adding just one feature. This post encourages discussion on the huge differences in these DSM Flash-Cache features now...

    RAM use and SSD cache - a Hindrance or boost for a home user?

    So I have a leftover NVMe M.2 drive sitting in a drawer because I replaced a 512 Western digital in my laptop with a Samsung 970 EVO plus 1TB. In other words...its "free" and currently useless. I am waiting for a 920+ to be delivered, with my use case Synology Photos, Family Files storage...

    SSD cache, M2D18 vs M2D20 considering drive compatibility

    I'm adding SSD cache to my RP2418RP+, and I'm looking at the M2D18 and M2D20. The M2D20 would be the obvious choice given the PCIe 3.0 performance except the drive compatibility list only including Synology drives, the maximum of which is 800GB. If I go for the older M2D18, I can find plenty...

    best cache setup for pair of ssd cards

    I have used a 512Gb NVMe card for cache, and soon will acquire one more. I have run cache advisor which suggests at least 1Tb for cache. Most of the large operations are reading not writing. Most bulk writes occur through slow transmissions, such as over residential fiber uplink. The system runs...

    How do you interpret the SSD Caching Advisor?

    Hi All, I recently ran the SSD Caching Advisor and it recommended 240 GB to me for my DS920+. What I would like to know is how do I interpret this value? Do I have to buy 2 ~240GB SSDs for each bay or am I supposed to buy like 2 ~120GB SSDs to make up the full 240GB? Also for future refence...

    Replace SSDs with HDDs

    Hi there ;) 1 year ago I bought a DS920+ with 4 SSDs from Seagate. Slowly I am realizing I made a mistake when buying it, for one simple reason: NAS SSDs are insanely expensive and hard to find. The SSDs are 1.92 TB each and for the amount of data I need they are not enough (I am using SHR)...

    Out with the old: In with the new: Another 4TB WD Blue to add to the volume - I've been very happy with these drives to date. It's only since the trading the RS1221+ fan noise for the Noctua silence do you get to fully appreciate the peace of SSDs. Usually when I open the door to the...
