# 4-Bay NAS Black Friday Deals Canada 2026: What to Buy Canonical: https://cloudzat.com/ca/black-friday/4-bay-nas-deals/ Market: CA | Currency: CAD ## Your Black Friday buying guide Put a four-bay NAS on your Black Friday shortlist and build the comparison around the drives, storage layout and backup you will need. Compare four-bay systems using the same disks and redundancy assumptions. Check networking, software and total delivered cost rather than treating the bay count as the whole specification. Judge the Black Friday offer against recent prices for the same enclosure and drive bundle; the worthwhile saving is on usable storage you can put to work. ## Quick answer Choose UGREEN DXP4800 Plus for a flexible four-bay server. Choose Synology DS925+ for the Synology software ecosystem. Start from the backup and sharing applications you want to use every week, then compare the drives and networking needed to complete either system. ## Current Listings Dates for 2026: Black Friday — November 27; Amazon.ca — November 19–30.

For a flexible four-bay server, choose UGREEN DXP4800 Plus. For a four-bay system focused on the Synology software ecosystem, choose Synology DS925+. ## Choose capacity and redundancy together Work out how much data you have now, how quickly it grows, and how much free space you need for comfortable use. A four-bay system can leave room to expand, but buying four drives immediately is a different budget from starting with two. Compare the complete enclosure-and-drive cost before choosing a larger chassis. A diskless NAS contains no main storage drives unless the offer explicitly includes them. Redundancy helps a system keep working after certain drive failures. It does not recover a file that was deleted everywhere, stop every ransomware incident, or protect the enclosure against theft or fire. Keep another recoverable copy of important files. A separate local backup and an off-site copy are sensible parts of a home or small-business storage budget. ## The network decides how useful fast drives become A NAS connects to your computer through a chain of interfaces. The NAS port, switch, computer adapter and storage workload all matter. Faster Ethernet on the enclosure provides little benefit when the computer remains connected at a lower rate. For occasional document backup, the simplest reliable connection may be enough. For frequent large media transfers, budget for the complete faster path. NVMe slots do not always serve the same role. Depending on the model, they may be usable for storage, cache, or a more restricted purpose. Check the enclosure documentation before buying SSDs for them. A cache is not automatically useful for a small number of sequential file transfers. Spend first on the capacity, reliability and network connection that address the workload you actually have. ## Match the operating system to the people using it Choose the applications and backup tools that your household or team will actually use. A capable processor is useful for some media and application workloads, but it does not replace an understandable administration interface or a dependable restore process. For a less technical household, a system with the right supported applications can be worth more than a faster system that nobody maintains. If you plan to replace the supplied operating system, check the exact model, boot process, storage controller and recovery procedure before treating the enclosure as a general server. Keep a copy of the original recovery instructions. Warranty terms and manufacturer support can differ when software or hardware is changed. Budget the time required to maintain the chosen system over its useful life. ## Select drives for the enclosure rather than by capacity alone Use the manufacturer compatibility information for the exact NAS and drive model. An ordinary desktop drive, a NAS drive and an enterprise drive can differ in recording method, noise, workload rating and support expectations. A SAS drive requires a SAS-capable controller; it is not a drop-in replacement for a SATA drive in a consumer NAS bay. For an SSD-only NAS, include the SSDs and any required heatsinks in the total. The quieter enclosure does not make flash capacity inexpensive, and a faster set of drives does not remove a slow network link. Confirm the supported SSD form factor, interface and mounting arrangements. Keep enough free capacity for the chosen filesystem and the way you intend to use snapshots. ## Choose the right alternative when a model is unavailable Keep the requirements that matter: usable capacity, bay count, required applications, network speed and room to grow. A different brand can be a good alternative when its software supports the job. A two-bay device is not equivalent to a four-bay plan that depends on later expansion, and an HDD enclosure is not a substitute for an NVMe-only workload. Compare a drive bundle with the same enclosure plus suitable drives bought separately. Check how many drives are included and the capacity of each drive. Do not count the advertised sum of every drive as the final usable capacity after redundancy. A genuine saving is a lower complete cost for a setup that still meets the capacity and recovery needs. ## A home backup NAS and an application server need different resources For file backup and ordinary sharing, dependable storage, clear access permissions and an easy restore process come first. Extra CPU cores may add little when the system mainly waits for a scheduled backup. For containers, virtual machines, media processing or several busy users, memory and processor headroom become more important. List the applications that need to stay responsive while a backup or maintenance task is running. A separate mini PC can run applications while the NAS concentrates on storing the files. That approach adds another device and a network connection, but it can make future upgrades simpler. A combined NAS server can be convenient when its hardware and supported applications fit the workload. Compare both complete arrangements, including storage drives, networking, backup and the time available to maintain them. ## Noise, placement and recovery matter after the sale Choose a location with ventilation, a stable network connection and tolerable drive noise. A multi-bay HDD system can be audible even when the enclosure fan is quiet. An SSD-only system changes the noise profile, but it also changes the capacity budget. Do not put a larger system in a poorly ventilated cabinet just because it fits physically. Access to the drives and power connection should remain practical. Write down how the files will be recovered if the enclosure stops working. Keep account recovery information, encryption recovery material where applicable, and a backup outside the enclosure. A storage system that can survive one failed drive still needs a recovery plan for other failures. Test the important files and applications after initial setup, while replacing a poorly suited purchase is still straightforward. ## Estimate usable capacity before ordering drives For a simple equal-size array, a rough single-parity estimate is the capacity of all but one drive; a dual-parity estimate leaves the capacity of two drives unavailable for user data. Filesystem overhead and decimal-versus-binary reporting reduce the figure shown by the operating system. Mirrors and mixed-size configurations behave differently. Use the capacity calculator as an initial estimate, then use the enclosure and filesystem documentation for the actual arrangement. Leave free space rather than planning to fill the estimated usable capacity immediately. ## Buying 4-Bay NAS in Canada For 4-Bay NAS in Canada, begin with UGREEN DXP4800 Plus for a flexible four-bay server.
