## Questions & Answers

**Q: What do i need to do/buy to fully use the m2. ssd slots capabilities?**
A: You need to purchase an m.2 SSD (NVMe, not SATA). The installation is tool-less - no additional hardware is required. You then need to use the in-built Storage Manager software to enable the SSD Cache feature. Easiest way to locate this is to open Control Panel and search for SSD in the top left. You only NEED one m.2 drive if you intend to use a read-only cache, though you can use two and set up in RAID 0/1. The reason for this is that if there is a loss of power or similar failure, your data is still stored on your main data drives. If you intend to use a read & write cache, you MUST have two m.2 drives as Synology DSM will insist they are set up in RAID 1. This is to protect from data loss should one of the drives fail whilst any data in the write cache is still mid-write to your main data drives. If you intend to use this second type of cache, read and write, consider purchasing a UPS (uninterruptible power supply) which can help to protect you against sudden loss of power to the drive as a result of a power cut. Hope that helps.

**Q: What is the max tb i can put into this. and what hdd sizes would i need for maximum storage with the option to make them protect all (5 drives) raid 5**
A: Maximum storage is 108TB it has 4 drive bays and 2x M.2 slots
 DSM specification
Networking protocol File system Supported RAID type
Storage management SSD cache

• Internal: Btrfs, ext4
Synology Hybrid RAID (SHR), Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6, RAID 10
• Maximum single volume size: 108 TB • Maximum system snapshots: 65,5367 • Maximum internal volume: 64
• Read/write cache support • M.2 NVMe SSD support
•

**Q: Can i use one 1x8gb ddr memory instead of using 2 x4gb memory (does it support 1 8gb module instead of 2x4gb module)**
A: 4Gb are onboard and you could not change it. There is a sodimm slot to increase the onboard memory, and officially it is supported a 4Gb stick, but I have a 8Gb reused from a laptop and people have put a 16Gb one. But check the brand / speed just in case.

**Q: Can you set this up. Bay 1 & 2 as a movie raid then 3 & 4 as a photo raid**
A: You can but if your going to use shr1 or raid 1 you would be better off creating a pool with all drives in raid 5 or shr1. You will get more storage space and you just create a share for movies and 1 for pictures. You can set a storage limit per share folder of you want

    Excellent full featured NAS - so much more than just a plug-in disk pack - Mac Montery compatible
  

*by G***T on Reviewed in the United Kingdom on 5 November 2021*

This is a great NAS from a company with a solid reputation and great support organisation.Storage devices are as important as the main PC in any computing environment that has grown to more than a couple of PCs and devices. Easy of use and reliability are key for on-going satisfaction.Remember - digital data can both last forever and be gone in a milli-second. The difference is backups and reliable storage devices.Some things I found out along the set up journey:Use SMB and not AFp for modern Macs.TImeMachine the mainstay of Mac based backups can be used with with NAS. Shared folders must have the "discoverable by bonjour" over SMB set on.When first setting up using bfs be sure to a put in all the drives that will be used.  I started with two drives then added two more but it took the device about 12 hours each to weave the later drives into the existing configuration. This is a result of having to redo the on disk data redundancy layout for the added drives.Use the same size drives if possible - I have 4 * 7TB drives that because of the redundancy scheme this provides 21 TB of storage and 1 drive failure redundancy.  Use proper NAS drives available from WD or Toshiba for best longevity.Adding 2 * 1TB cache M1 ssd sticks helps performance when the load ramps up but I do suspect that write through to disk happens. Use gigabit wired networking not wifi for moving larger amounts of data. I was getting reliably about 100Mbytes/second writing from a MacBook Pro with ssd drive over a wired connection.  Time machine is a bit slower but not much.I was stuck for a while getting "Note enough space" messages on both Mac systems that were using the device. After a very pleasant interaction with support they found a quota setting on the user name was being correctly enforced.  Case opened and closed in the same day.You can move data three main way between a Mac and the device :Up/down load using the File Station software accessed via a web browser,Mount a shared folder and use the finder,Mount a shared folder and use the command line in terminal.Use Time Machine for backups.The disk manager software on the NAS has many option and can be extended with extra software. The fine grained controls over users and data access are great. This model has a Celeron processor and I suspect that the virtual machine experience may not be great. However for long term NAS usage lower power consumption is preferred.Let's talk about the noise.  In a silent office you can hear the device but it's not unpleasant. Being quieter than a coffee machine or someone tapping on a mobile phone. I imagine the NAS case as a holding place for data chipmunks so the gentle activity noise is reassuring.  Some extra sound dampening would be good though esp. when the drives are spinning up. The device drive activity is not predictable when using Time Machine or multiple shared folders.Overall a great device and worthwhile addition to my computer community.

    Superb Media Player and Server
  

*by M***D on Reviewed in the United Kingdom on 20 June 2023*

I purchased this as a media player and for holding my photos after a session, I know nothing about Linux or how a NAS works. I did watch several videos on youtube and configured the device very easily.I installed a single 14tb Toshiba NAS drive then over 3 months bought another 4, 2 for my NAS and 2 for my DASThe difference between a DAS and NAS - DAS is Direct Attached Storage and is constantly connected to your computer like a hard drive or USB stick.A NAS is Network Attached Storage, this is connected to your router and accessed via your laptop or desktop pc via a URL. I have mine configured to SHR using 3 discs, if one fails the drive is replaced and the discs automatically copy the data to the new disk.I regularly backup from my NAS to my DAS and use this as a backup medium using free software called FreeFileSyncI have all my movies and TV series ripped to it and watch them through Jellyfin along with all my photos when out and about.We recently went to the Lake District and I connected my laptop up via Ethernet as it's faster than wifi, streamed a movie via Jellyfin to the TV. Since then I have installed TailScale which is a VPN to make it more secure and watch movies through this application from anywhere using any device. After taking 1000's of photos each day I would upload them back to the NAS which did take some time but upon getting home no messing about copying files etcThis took a bit of working out but eventually got there.I just wish I'd have bought one of these devices years ago, the software which comes with this Synology is perfect. Really polished off and makes it a doddle to use and set up

    Could do with better noise insulation
  

*by Z***M on Reviewed in the United Kingdom on 20 September 2022*

All good and as expected from a Synology NAS device, easy to use, easy to setup and breadth of features for novice to pro user.Two things I noticed were, if you setup a file transfer (for example to backup or transfer from an existing NAS by setting up as a remote folder to copy from, to the device), when the web portal times out or requires you to sign in again, the file transfer window disappears, you can tell the transfer is still in place by checking the resource monitor which shows CPU/LAN and Volume activity, however no way of getting the transfer window back ( unless you setup a dummy transfer , at which point it will show all transfers, you can then cancel the dummy transfer, a little annoying but hopefully only have to deal with on the rare occasion).Now the most annoying, there is no sound insulation on the device, probably not an issue if you are ussing SSD or smaller mechanical HDs at around the 10TB mark, however with the newer larger sizes of 18TB etc, the sound is frustrating on power up, seek and transfer. There are links online to try to reduce the sound but these do seem quite amateur and dont provide ample resolution.Think about device placement if the sound issue is an issue, which it most definitely will be for a lot of people.
