Popular NAS-maker Synology has confirmed and slightly clarified a policy that appeared on its German website earlier this week: Its “Plus” tier of devices, starting with the 2025 series, will require Synology-branded hard drives for full compatibility, at least at first.
“Synology-branded drives will be needed for use in the newly announced Plus series, with plans to update the Product Compatibility List as additional drives can be thoroughly vetted in Synology systems,” a Synology representative told Ars by email. “Extensive internal testing has shown that drives that follow a rigorous validation process when paired with Synology systems are at less risk of drive failure and ongoing compatibility issues.”
Without a Synology-branded or approved drive in a device that requires it, NAS devices could fail to create storage pools and lose volume-wide deduplication and lifespan analysis, Synology’s German press release stated. Similar drive restrictions are already in place for XS Plus and rack-mounted Synology models, though work-arounds exist.
Synology also says it will later add a “carefully curated drive compatibility framework” for third-party drives and that users can submit drives for testing and documentation. “Drives that meet Synology’s stringent standards may be validated for use, offering flexibility while maintaining system integrity.”
How do you fit 32 terabytes of storage into a hard drive? With a HAMR.
Seagate has been experimenting with heat-assisted magnetic recording, or HAMR, since at least 2002. The firm has occasionally popped up to offer a demonstration or make yet another “around the corner” pronouncement. The press has enjoyed myriad chances to celebrate the wordplay of Stanley Kirk Burrell, but new qualification from large-scale customers might mean HAMR drives will be actually available, to buy, as physical objects, for anyone who can afford the most magnetic space possible. Third decade’s the charm, perhaps.
HAMR works on the principle that, when heated, a disk’s magnetic materials can hold more data in smaller spaces, such that you can fit more overall data on the drive. It’s not just putting a tiny hot plate inside an HDD chassis; as Seagate explains in its technical paper, “the entire process—heating, writing, and cooling—takes less than 1 nanosecond.” Getting from a physics concept to an actual drive involved adding a laser diode to the drive head, optical steering, firmware alterations, and “a million other little things that engineers spent countless hours developing.” Seagate has a lot more about Mozaic 3+ on its site.

Drives based on Seagate’s Mozaic 3+ platform, in standard drive sizes, will soon arrive with wider availability than its initial test batches. The driver maker put in a financial filing earlier this month (PDF) that it had completed qualification testing with several large-volume customers, including “a leading cloud service provider,” akin to Amazon Web Services, Google Cloud, or the like. Volume shipments are likely soon to follow.

There is the mental image that most people have of electronics recycling, and then there is the reality, which is shredding.
Less than 20 percent of e-waste even makes it to recycling. That which does is, if not acquired through IT asset disposition (ITAD) or spotted by a worker who sees some value, heads into the shredder for raw metals extraction. If you’ve ever toured an electronics recycling facility, you can see for yourself how much of your stuff eventually gets chewed into little bits, whether due to design, to unprofitable reuse markets, or sheer volume concerns.
Traditional hard drives have some valuable things inside them—case, cover, circuit boards, drive assemblies, actuators, and rare-earth magnets—but only if they avoid the gnashing teeth. That’s where the DiskMantler comes in. Garner Products, a data elimination firm, has a machine that it claims can process 500 hard drives (the HDD kind) per day in a way that leaves a drive separated into those useful components. And the DiskMantler does this by shaking the thing to death (video).

The DiskMantler, using “shock, harmonics, and vibration,” vibrates most drives into pieces in between 8–90 seconds, depending on how much separation you want. Welded helium drives take about two minutes. The basic science for how this works came from Gerhard Junker, the perfectly named German scientist who fully explored the power of vibrations, or “shear loading perpendicular to the fastener axis,” to loosen screws and other fasteners.
As Garner’s chief global development officer, Michael Harstrick, told E-Scrap News, the device came about when a client needed a way to extract circuit boards from drives fastened with proprietary screw heads. Prying or other destruction would have been too disruptive and potentially damaging. After testing different power levels and durations, Garner arrived at a harmonic vibration device that can take apart pretty much any drive, even those with more welding than screws. “They still come apart,” Harstrick told E-Scrap News. “It just takes a little bit.”
Improving the recovery and sorting ease of hard drives is itself a useful thing, but the potential for rare-earth magnet recycling is particularly attractive. Most rare-earth magnet recycling involves “long-loop” recycling, or breaking them down into rare earth elements and then putting those back into the magnet production stream, which is energy-intensive and not very cost-effective. Electric vehicles and wind turbines have huge amounts of rare-earth magnets in them but rarely see recycling. Hard drives, while individually small, are massive in scale, with roughly 259 million shipped in 2021.
One Canadian firm, based on a University of Birmingham-patented process, wants to reuse drive magnets more directly, creating new sources that don’t require extraction and aren’t quite so globally concentrated. That Canadian firm, HyProMag, uses robotics to find and extract drives’ permanent magnets, then sends the rest of the disk off for recycling.
The technology is not all there yet, but soon enough, it looks like something interesting will shake out.
