    Mac clients - SMB cache issues

    I updated my NAS (a DS418Play, as detailed above) to DSM7.0-41890, hoping that would resolve the issues I have been experiencing with SMB shares from a Macintosh (running Big Sur 11.5). DSM7 has a much more up-to-date version of Samba (4.10.18) than used to be the case with DSM6.2 (4.4.16 at...

    Synology cache info menu

    In DSM 6 there was a windows that showed the info on the cache, "amount, hit rate etc." Anyone know of a replacement of sorts since DSM 7 removed it, maybe through Docker? Here's the old on for reference: TIA

    DSM 7.0 Q: What is the different between buffer and cache

    As you can see the screenshot below, it was from Resource manager->Memory tab. What is the different between buffer and cache? When the buffer/cache is used? I know when I transfer large files, the cache can be increased to 15GB. Thanks

    Hi I would like to buy the Seagate IronWolf 16TB (ST16000VN001) for the DS920+ I read online that the 12TB and 10TB version comes with an old Firmware (SC60) that does not support Write Cache. The firmware version SC61 should solve the problem. Does this model support it? Thanks!
