Western Digital (WD) is about to get some stiff competitors from its primary rival Seagate. The 2 corporations management the vast majority of the spinning media market today, and have been one-upping one another these days with regards to storage capability. WD not too long ago took the capability crown with its new 26TB onerous drives. Now Seagate is about to leapfrog that quantity with 30TB onerous drives it says will arrive a yr from now.

The key to Seagate’s newfound aerial density is its second-generation Warmth-Assisted Magnetic Recording expertise, or HAMR. It’s been utilizing its first era HAMR since 2018, however by no means on a high-volume product. The corporate acknowledged final yr that it anticipated its second-generation HAMR would enable for 30TB capacities and past. HAMR works by briefly heating up the magnetic media to get bits to flip. The media is heated with a laser to 450 levels Celsius, then cooled to room temperature in a nanosecond.

Transferring to a mass-produced HAMR line of onerous drives is a giant deal for Seagate. It requires virtually a completely new drive with new media, heads, actuators, and extra. The tradeoff is it would pave the best way to unimaginable features in areal density within the coming years. Seagate’s present 20TB have an areal density of 1.116 Tb/inch2. With HAMR, it may be elevated greater than twofold to 2.6 Tb/inch2. Ultimately it expects to hit 6 Tb/inch2 by 2030. This might theoretically enable for 100TB onerous drives, in response to Tom’s {Hardware}.

There’s a draw back to those features although. Given how a lot must be modified internally for HAMR second-gen, they’re anticipated to be costly. As such, they could do what they’re doing with HAMR drives now, which is just supply them to pick clients within the enterprise and information heart markets. If that’s the case, it’s unclear once they is likely to be offered to common clients.

Regardless of the difficulties, Seagate continues to be planning on transferring forward with its plans. Its roadmap signifies it would produce 30TB HDDs subsequent yr, adopted by 40TB in 2024. By the point we get to 2025, a 50TB onerous drive must be accessible.

Information of Seagate’s developments comes at a tough time for the magnetic storage business. Final week a report got here out exhibiting shipments of HDDs have declined over 30 p.c year-over-year. The primary elements for the drop-off embody gentle demand for PCs together with the continued transition to solid-state storage. Nonetheless, demand stays regular for information facilities, which is the place Seagate’s 30TB drives will doubtless find yourself, not less than initially.
