    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.


    How do I shut down QNAP NAS
    If you have the admin access to the web interface, then select shut down from the power menu. If not, press the power button for 1.5 seconds till you hear a beep. On doing this the system starts the shutdown process ( and it shows so on the LCD screen if your NAS has one). It takes about 5-7 minutes for the system to stop services, unmount volumes and then shutdown safely. If you want to shutdown immediately, then keep the power button pressed for 5 seconds – this is equivalent to pulling the power and may corrupt the volumes though.

    Which QNAP NAS is good to buy
    QNAP has a model for almost every single processor available so the choice of NAS is overwhelming. Generally 51K, 51+ and 53D are very popular models. Decision on which model to buy will greatly depend on what you want to use your NAS for, and your budget.

    How Does QNAP 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 do I use QNAP NAS
    Basic setup starts with QNAP finder on a PC. Connect your QNAP to the power and network, find it with QNAP finder and then follow the GUI setup wizard. Finally you will be able to login to your QNAP and use it though Web browser or through the Mobile apps.

    What is Thick Volume in QNAP
    With QNAP thick Volumes you specify the total volume space at the time of creation, and that much space is actually set aside for your volume. This is in contrast with Thin volume where the volume expands to take as much space as it needs , providing overprovisioning. Use thick volume if you want to keep guaranteed space aside for your volume

    how much is qnap extended warranty
    QNAP Warranty extension cost varies from model to model. Further the extended warranty can only be bought within 9 months of purchase of the unit

    qnap how much space for snapshots is reserved
    You can set the maximum space allocated to Snapshots. Typically it should be 20-30%. The actual space the snapshots occupy depends on how much snapshot data differs from actual data on disk.

    qnap how to replace failed drive
    Drives are hot swappable which means you don't have shut down the unit. If you are on RAID 5 , then you only have 1 HDD failure tolerance, and it's 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.

    What QNAP Means
    Quality Network Appliance is acronymed to QNAP. QNAP is one of the most popular brand of Network attached storage (NAS) globally.

    qnap what is snapshot
    Snapshots allow you to Roll back your data to a previous state. They are the best protection against Ransomware too since they work at the block level and not visible to the file system.

    qnap what is qts
    QTS is the name QNAP has given to its operating system. There are 3 OS with QNAP now - QTS which is for basic NAS, QES for enterprise and QTS hero which is a mix of QES and QTS

    qnap what is raid scrubbing
    Raid Scrubbing checks the data on your RAID for any silent corruption and tries to repair it. QNAP RAID Scrubbing can be run manually or on schedule. Remember that Scrubbing slows the system down so it's better to run it when the system is not in use.

    which qnap for home users is good
    There are 3 series popular with home users in 2021 - 31K, 51+ and 53D. You can choose depending on your budget and features you need.

    qnap why two ethernet ports are there
    Multiple ports are there so you can either join them ( team, link aggregation ) so they act as one IP address and increase the bandwidth. Or you can put them in failover so if one port fails, the other takes over.
