Welcome to big Red.
WD’s Red series of NAS drives has proven to be a winner for the company, with excellent performance and reliability making them the NAS drive of choice for many system builders. Until recently, the largest capacity was 8TB, but WD has just bumped this to 10TB, making it one of the largest mechanical drives on the market.
The new 10TB model is limited to a maximum of eight drives in a NAS, but that’s still a whopping 80TB of storage. It’s built using the HelioSeal helium-technology as prior WD Red drives, which replaces the air inside the drive with helium. This is one seventh the density of normal air, and allows for better performance and reliability.
It’s built inside a standard 3.5-inch drive chassis, and also includes WD’s NASware 3.0 technology. This is designed to improve disk reliability and system performance, as well as optimising the drive for use in a multi-drive environment. The drive includes a 256MB cache, while the seven platters inside spin at 5,400RPM. There’s a three-year limited warranty included, but not much else in the way of software for backing up old systems. Connectivity is via the SATA 3 6Gbps port, which is fine for a mechanical drive.
We used CrystalDiskMark to measure performance, and saw sequential read speeds of 211.5MB/s and write speeds of 212.4MB/sec. Heading down to 4K performance, we see 0.714MB/sec read speeds and 2.767MB/sec write speeds. This puts it on par with other NAS drives, although it’s by no means the fastest kid on the block.
At $629, the price per Gigabyte is just 16c. It’s not quite the cheapest mechanical hard drive on the block, nor the fastest, but that 10TB in size will be appreciated by those with NAS devices that don’t have a plethora of bays to fill. WD has nailed it once again with the latest iteration of the Red, and there’s even a Pro version for $100 more that has a five-year warranty and runs at 7,200 RPM. To be honest, we’d probably spend that little extra for the performance jump, but even at 5,400 RPM the WD Red 10TB does just fine.
