Thecus W5000 WSS NAS Review

Low-cost Windows Storage Servers (WSS) give small businesses access to enterprise-class features at a desktop price.

Sequential Mixed Data Sweep

Applications like video editing, which pull files from the NAS, involve reading and writing data at the same time. SATA devices are inherently handicapped in these workloads because they communicate over a half-duplex interface. SAS is full-duplex, but most of us can't afford to run arrays of expensive, hot-running SAS-based disks. Mounting an iSCSI share in a desktop allows the host PC to see the resource as a local drive. The NAS can then work around the limitations of SATA with cache.

That works out great when you have sufficient read and write performance to sustain solid mixed workload numbers. Unfortunately, the W5000 doesn't fare particularly well writing data, and in this sequential chart, you can see the metric is mired as a result.

    Um, is this a hardware review or a press release?

    While many people may actually use RAID 5 with this device, this is what we call professional malpractice among IT pros.

    You need to understand a couple of things about all of those articles. The articles are not talking about your home or small business NAS with four or five drives to start with. The ZDNET author has a history of writing articles and article titles to bring people in. Many disagree with Robin's findings. I wouldn't say that is the case with the only article that relates to this review though, Why RAID 5 Stops Working in 2009. In that article he references a 7-drive RAID 5 array. With 6 or more drives we use RAID 6 (RAID 10 in some cases) for the very reason he cites. With five drives and in a home or small business environment RAID 5 is sufficient as long as you are proactive. Keep the system on a battery backup, keep air vents fee of dust and if a drive fails replace it right away.

    Some users may want to take redundancy to the next level and run RAID 6 on a 5 drive array. That is fine and I know people that do. I don't recommend it on a sub-1000 Dollar system that already has performance issues with RAID 5 though.

    "We rarely hear of failures in the field"
    Here I am.
    "In our own experience, NAS failures come from easy-to-replace fans and power supplies, rather than the main components that make up the heart of the system."
    Changed power supply and changed fan but still no fun.
    I had to dump my DS411Slim after putting some € on it in an attempt to fix.
    The brown thing happens.
