Seagate has refreshed its consumer and prosumer line with two bus-powered 3.5-inch desktop hard drives and an eight-bay Thunderbolt 5 RAID enclosure that scales to 256TB.
The One Touch desktop drive comes in 8, 20 and 24TB, and a single USB-C cable carries both power and data, which removes the wall adapter a 3.5-inch external normally ships with. Seagate bills the design as the industry's only bus-powered USB-C for desktop hard drives. That superlative arrives with no named test behind it; the more useful number is the 8TB unit, which sells through the Seagate Store and authorized partners starting at $259.99.
FireCuda X Vault is the same trick in gaming trim, offered at 8 and 20TB with customizable RGB lighting, Windows Dynamic Lighting support, Xbox on PC certification and a Game Pass trial, starting at $269.99. No capacity is attached to that price, and the range stops 4TB short of the One Touch at the top. What the gaming badge adds is lighting and a certification, not capacity.
At the other end sits the LaCie 8big Pro5, in 32, 64, 128, 192 and 256TB configurations, with Thunderbolt 5 bandwidth of up to 120Gb/s, up to 2,800MB/s in RAID 0, up to 140W of power delivery for a laptop, RAID Manager software and a five-year limited warranty, starting at $5,979. Camera Jabber, covering the same launch, adds up to 2,500MB/s in RAID 5, hot-swappable bays, and three Thunderbolt 5 ports of which one takes the host and two allow daisy-chaining.
Only one piece of arithmetic here is clean. The One Touch at 8TB and $259.99 works out at $32.50 per terabyte; the $269.99 and $5,979 entry prices carry no stated capacity, so cost per terabyte across the rest of the line is unknown. Whatever those ratios turn out to be, the premium in the LaCie sits in the enclosure, the Thunderbolt 5 controller and the hardware RAID rather than in the media.
Plenty else is missing. No source names the drive mechanisms inside any of the three products, none gives a sustained transfer rate for the single desktop units, and none gives idle or active power draw, which is the figure that matters most for a device now pulling everything down one cable. Availability is asserted for all three, but only the One Touch is described as purchasable today at a price tied to a specific capacity.
Lance Ohara, Seagate's vice president for edge IoT, framed the refresh around AI-assisted creation making personal files larger and longer-lived, and around storage built to scale for what AI brings next. Decoded, neither the media nor the format has changed. What changed is the connector, the capacity ceiling, and the fact that a consumer line is being introduced by the executive who runs edge IoT.
Bootnote: a 3.5-inch mechanism has always wanted more than a laptop-class USB port could supply, which is why desktop externals shipped with a power brick and 2.5-inch portables did not. USB-C power delivery is what makes a bus-powered 3.5-inch enclosure arguable at all, and Seagate has not detailed how these drives stay inside that budget through spin-up.
