    Does Synology DS-220+ have Hot Swap

    Yes, you can hot swap the hard drives. Remember your RAID will rebuild so give it ample time to rebuild if you plan to swap more than one drive.

    which synology nas should i buy

    If you are an End user and on a budget go with j series – 220j or 420j. If you are power user go with Plus series ( DS-220+, DS-720+ or DS-920+). If you are a business user, contact us and we will suggest a model that suits your need depending on the number of users and features you need


    synology how to replace failing drive

    Drives are hot swappable which means you don’t have shut down the unit. If you are on RAID 5 or SHR1, then you only have 1 HDD failure tolerance, and its advisable to not use the NAS while the RAID is being rebuilt. Replacing hard drive is as easy as pulling the bay housing the failing/failed drive, and replacing with a new drive.


    synology what is data scrubbing

    Data you store on the hard drives is subject to silent corruption ( called Bit rot). With Data Scrubbing, your data is checked periodically to ensure that there is no bit rot and data is accurate. If an inaccuracy is found, Synology DSM will attempt to repair the data using the redundant copy. So with Data Scrubbing the chances of your data Silently getting corrupt is minimized.


    synology where is dsm installed

    DSM is installed on the hard drives/ssd. First time you power on the unit ( or power on an existing unit without Hard drives), it prompts you to install the DSM. On the higher units, there might be DOM (Disk on Module) but you need the DSM on hard drive/SSD to boot the unit


    who makes synology hard drives

    Synology Hard drives are manufactured by Toshiba, they are Toshiba MG enterprise drives. However they have a specific firmware which enable a deeper integration with Synology DSM


    how many camera licenses are free with Synology

    With Synology 2 Camera Licenses are free. Others can be bought in a pack of 1, 4 or 8


    synology how often data scrubbing is performed

    Data Scrubbing takes place according to the schedule you set


    how Does synology NAS work

    All the Major NAS work the same way. At the very basic – you connect them to a network, define basic permissions and settings and then anyone on your network ( or outside the network if you configured cloud) can access it on PCs and mobile devices. Contact us if you want to see a demo


    How to buy synology surveillance station license

    Licenses are issued as paper licenses with a serial key. Use the serial key to register the license on Surveillance station. We sell surveillance station license also online.


    which synology nas for plex

    Plus series ( DS-220+, 720+ and 920+) works well for Plex. This series does the Hardware transcoding too. Refer to Plex NAS compatibility List for more information


    how many volumes on synology can be setup

    Synology allows 64-256 volumes ( varies by models) to be setup but you would typically be setting up 1 or 2 volumes and multiple folders inside, say an SSD volume and an HDD volume. Most of the time you are looking at minimizing the number of volumes you create.


    synology how many users can be accomodated

    DSM allows 2048 to 16,000 users depending on the model to be created. However the actual number of concurrent users who can work comfortably depends on the hardware. For example 220j allows 2048 user accounts, but not more than 6 users can connect without a performance degrade


    synology how many virtual machines can be run

    Virtual Machines can only be run on models support VMM. Number of Vms that you can run depend on the VM workload , typically Number of CPU threads, and the memory requirement are 2 important variables to keep in mind while calculating the max number of Vms your machine can support. There is no single formula to calculate but the Free CPU power and Ram, Divided by the CPU power and ram of each VM gives you a fair idea


    synology how many drives can fit

    Depending on the unit there can be 2 to 24 drives. Look at your model specification sheet to see the number of 2.5”/3.5” SATA bays. Some models can be expanded too


    How does Synology SHR work

    Synology SHR allows you to mix different sized drives without wasting space. SHR1 is equivalent of RAID 5 and SHR2 is equivalent of RAID6. At the most basic – it creates multiple partitions on the drives each equal to the lowest size drive and then applying a RAID treating each partition as an individual drive.


    Synolgy Why should I have multiple volumes

    Typically you would want a single large volume with multiple folders inside. However in some cases you may want to make multiple volumes like when you mix media ( SSD fast volume and HDD slow volume), or you want different raid levels ( RAID 6 volumes for important data, RAID 5 volume for second backup) or if the upper size limit of the volume is reached and you can’t expand it any further.


    Synolgy Why Should I upgrade RAM

    If you have RAM intensive processing running on your NAS, it helps to upgrade. Look at your system status and see the RAM usage. If its peaking, a RAM upgrade will help. If the current memory usage is above 90% for example, you can improve performance by adding RAM. If you run VM or Docker, then you would definitely need more RAM


    What is Synology Active Backup

    Synology Active backup for business is a backup application that allows you to backup your servers, virtual machines and desktops. It allows you to restore on a file level or bare metal recovery


    What is Synology DSM

    DSM (Diskstation manager) is the name Synology has given to its operating system. Each NAS is like a little PC with its own CPU, RAM and OS.


    Which is better between Synology and QNAP

    Both of them are great NAS brands – the top in the NAS category . This question is like which is better- iOS or android. Typically QNAP offers more hardware choices and hardware tweaking options. Synology on the other hand has more stable and easier software UI. The one you should go for , greatly depends on the actual requirement you have.
