Question 1

How secure is this against malicious attacks? Does it have a firewall and anti-virus software?

Accepted Answer

The DSM software come with a number of features to prevent malicious attacks.  One of my units was hit with a ransomware attack.  Nothing import on the unit as it was used for security camera video storage.  I believe I was hit with what is called man in the middle hack.  My credentials were taken when I periodically logged in to view the camera images.  I was not taking the security seriously.  Now I have turned on HTTPS and 2FA (two factor authentication).  Point is that the features are there to secure you NAS but you have to make use of them.  Hope this helps.

Question 2

Can i put an 8tb m.2 in the m.2 slot

Accepted Answer

No.  The M.2 is for cache only and limited to 2GB each NVMe.  WARNING-  it is very picky for NVMe's.  I tried it with WD and Samsung and they burned out within 6 months.  Synology sells NVMe's that they make and I would recommend.  I don't like being stuck to the MFG drives, but they work.  Just based on personal experience.  Synology 920+ (8GB Ram, 4 x 16tb Seagate Exos X16)

Question 3

how much storage space come with this device?

Accepted Answer

None.  You need to buy hard drives

Question 4

would this unit support a NVME cache module?

Accepted Answer

Yes the Synology DS1522+ supports 2 of the NVMe M.2's in mirror (RAID1) for write-back cache, or just 1 of them for read-only cache. (You cannot force it to use 1 of them for read-write). Starting with the year 2022 models, as of date of this review October 2022, Synology no longer lists as compatible any drive except their own brand (vendor-lock). However, if you look at the prior version of this unit Synology 1520+, you'll see other options that DO work like certain Seagate m.2 Ironwolf (but not all of them)..

Unfortunately, the Synology DSM 7.1 in these newer 2022 models will currently show a warning anything except their own brand of drives may not support all features and compatibility is not guaranteed either. Customers are not happy about this vendor-lock situation, hopefully Synology will cave in and certify other drives in the future.
