Hi Shadow, even experts make this mistake. M.2 is only one of the SSD options. 1815+ for example, which I have supports 2.5" SSD's with screw or you can use an 2.5" to 3.5" adapter. However direct connection is recommended with the cache for an extra speed-boost, although after testing, not necessary for small business. The adapter works great.
Hi Chris kchrischa, I did some research. After some reading it turns out only select models support 2.5" or M.2 nvme sized SSD. Check the spec sheet for your model and if it doesn't say anything, most likely the answer is a no. As your tech sheet clearly states, the answer is yes.
Hello Shanti,While this is not direct answer to your question, I have the same setup DS218+, two 4TB hard drives as Storage Pool 1 (RAID 1) and as Volume 1, and external 480GB SSD as Storage Pool 2 and Volume 2.
What I did is installed MariaDB, Web Station, VMM, PHP and all other disk intensive apps on Volume 2. With this I didn't get exactly cache but got SSD performance boost. And for my needs it proved to be very good solution.
I also do daily backup of everything from Volume 2 to Volume 1, because SSD is JBOD.
sudo vi synoinfo.conf
internalportcfgand replace existing value
esataportcfgand replace existing value
"0x0"and save and exit file
You can backup them up using the Snapshot replication package. Would not recommend using HB as a backup tool because you might get into trouble with the restore process.Ideally I would like to keep the ABB backups on the SSDs and only push them to the HDD every few days but I don't think it is supported. So I will have to keep all ABB versions on the SSDs and consequently on the HDDs through the Hyper Backup
Regarding SSD support I cant speak for Crucial drives as I have never tried them but I see no reason for them not working. On top of that WD blue or RED SSDs will work for sure without any problems.So my questions are
Not sure what the question is here, but if it's are you able to restore from one volume to the other using HB then the answer is yes, its possiblerestore the JBOD directly from the hyper-backups on the EXOS volume?
The only reason for this selection was to achieve the 4TB capacity our of the 2 SSDs. This is the reason I asked for opinions on the Kingston one ( SEDC450R/3840G) so that I could eventually use one instead of 2. The only review I can find is this one but I do not have the background to understand everything other than the conclusion that it is a .. nice drive But i do get your point of swapping in the future so probably the single SSD is better..Maybe reconsider JBOD setup, to begin with. Not sure what you will get with that kind of setup and in the long run you might get into trouble if you want to swap those drives out.
ok so to clarify: If I go with the 2x2TB SSDs, and one of them fails, can I just find a single 4 TB disk (either HDD or SSD) and restore the backed up volume to it so it will not require me to re-configure all synology packages and docker containers?Not sure what the question is here, but if it's are you able to restore from one volume to the other using HB then the answer is yes, its possible
Of double "basic" drive (giving you 2 separate volumes) or a RAID0 (stripe) configuration that will give you a single volume with the double capacity options.But i do get your point of swapping in the future so probably the single SSD is better
Not that easily, no. Depending on the configuration of those SSD drives you will have problems with a simple restore, especially in JBOD.ok so to clarify: If I go with the 2x2TB SSDs, and one of them fails, can I just find a single 4 TB disk (either HDD or SSD) and restore the backed up volume to it so it will not require me to re-configure all synology packages and docker containers?
