    Ultimate data protection

    ASUSTOR NAS devices support RAID to help protect your data and increase performance. RAID mainly revolves around the core concept of combining your hard drives to protect data inside. Each RAID level offers a differing degree of data protection, system performance and capacity.
    RAID 0 and JBOD can combine the capacity of several hard drives into a larger storage space. RAID 0 or JBOD volumes offer no any sort of data protection and cannot migrate to other RAID levels or capacity expansion but RAID 0 does increase read/write performance.
    RAID levels above RAID 0 help provide protection against drive failures by introducing redundancies. The number of faulty drives tolerated vary across different RAID levels. When combining drives of differing sizes, the total capacity will be calculated based on the size of the smallest drive.
    ASUSTOR's supported RAID levels are summarized in the chart below:

    RAID Level Single JBOD RAID 0 RAID 1 RAID 5 RAID 6 RAID 10
    Minimum number of drives 1 2 ~ 16 2 ~ 16 2 3 ~ 16 4 ~ 16 4 ~ 16
    Faulty Drives Tolerated 0 0 0 1 1 2 1
    Total available capacity Drive capacity Total capacity of all drives Total capacity of all drives Capacity of smallest drive (Capacity of smallest drive) * (Total number of drives - 1) (Capacity of smallest drive) * (Total number of drives - 2) (Capacity of smallest drive) * (Total number of drives / 2)

    M.2 Storage – Take Control of Your NAS

    With the introduction of M.2 storage on an ASUSTOR NAS, you are now able to choose how you store your data. With M.2 caching, your NAS automatically stores frequently used data on installed M.2 drives. With the all-new M.2 storage feature, M.2 SSDs provide levels of sequential and random performance that are unattainable for most hard drives. Combine M.2 SSDs with an ASUSTOR NAS to access, modify, copy and move up to thousands of files, such as photos, music and raw video and audio editing projects at extreme random performance while ASUSTOR NAS devices featuring 10-Gigabit Ethernet become an ultra-high sequential speed storage volume able to move large files between PCs and NAS quickly.
    Files stored in this volume can be accessed quickly and remain there no matter how often they are accessed. Create content quickly and easily on the M.2 SSDs and then archive work on the hard drives to create a powerful high-speed, high capacity workspace. Play games? Create an iSCSI volume on your NAS on the M.2 SSDs to create an easy way to play games without running out of storage on your laptop. Unleash the full potential of your NAS by utilizing the full speed 2.5 and 10-Gigabit ports while also increasing the maximum total storage your NAS can handle, making ASUSTOR the number one NAS available.

    * To maintain optimal performance and quality, M.2 drives may only be paired with other M.2 drives in a RAID array.

    Smarter Stability

    When system volume usage approaches 100%, system performance and stability may decrease. ADM strengthens management and monitoring of system storage space usage to keep your NAS stable and fast. After usage rates approach 95%, Snapshot Center, in addition to other stability measures found in ADM, adds an option to prevent storage space from being completely used up by deleting older unlocked volume snapshots to preserve data integrity while maintaining system stability.


    System requirements for Volume snapshots: AS31, 32, 40, 52, 53, 54, 61, 62, 63, 64, Drivestor Lite (AS11TL), Drivestor Gen2 (AS12), Drivestor Pro Gen2 (AS33 v2), Lockerstor, Lockerstor Gen2, Lockerstor Gen2+, Lockerstor Gen3, Lockerstor Pro, Lockerstor Pro Gen2, Flashstor, Flashstor Gen2

    Frequently Asked Questions

    Q:How to setup direct connection between the NAS and the PC via a LAN cable

    By connecting the NAS to the computer directly via LAN cable, the NAS shell retains its default static IP address which is 169.254.1.2(LAN1), configures the PC LAN IP address to the same segment(for example 169.254.1.10), then you can use ACC to scan and list the directly connected NAS information.

    Q:How do I initialize my ASUSTOR NAS?

    A: ASUSTOR provides a variety of quick and convenient ways for you to initialize your NAS. After a simple initialization procedure, your NAS will be online and ready for use! Below, we will illustrate how to initialize your NAS using its LCD is play or using a computer. For ... Learn more about this >

    Q:What is the maximum number of expansion units supported on an ASUSTOR NAS?
