Exactly what I wanted to know.
I mean I'm an IT person but Xpenology/Synology is great due to the apps, I just can't be arsed doing much IT stuff outside of work these days .. it's so easy to do handy stuff like .. download station. Had my HP N40 for probably 10 years at this point!
I totally agree with you. From a cost perspective, I have no complaints. Synology can also fail though the possibility is relatively low. With the same cost you can build 5-6 Xpenologies. FreeNas is a great option though I think Synology/Xpenology is much easier to use for non-IT folks. In regards to vulnerability, if you are run it within a LAN, there are not many attack vectors.
Been there done that, it's okay for a test lab or for storage of none critical data but for production / office use or critical data storage I wouldn't touch it. It's far safer to use freenas or something along that line. Xpenology fails when it comes to security as allot of the time exploits or vulnerabilities are discovered by them or Synology and the xpenology folks simple haven't managed to roll out an immediate workable update which closes those vulnerabilities, so until they do you have to wait, wait, wait and failing that you can risk using the official Synology patch via the DSM interface which allot of the time works, but it can at times disrupt the operating functionality of your xpenology system causing it to fail and if it fails it can be a real long winded pain in the backside recovering it. Whereas carrying out an official update on your official NAS is (9.9x out of 10) is as simple as pushing a single button. I've used xpenology for years , so I'm talking from experience. It's not for most people, especially when something goes wrong. Something like freenas is far safer to use in my opinion.
