How these two compare
Sequential throughput
Toshiba N300 HDD 12TB holds the higher sequential rate. Seagate SkyHawk AI 12TB is rated 250 MB/s read and 250 MB/s write, Toshiba N300 HDD 12TB 253 MB/s read and 253 MB/s write; a spinning disk's throughput rises with platter speed and density and barely differs between reading and writing.
Price
Seagate SkyHawk AI 12TB lists at 456,38 €, or 38,03 € per TB; Toshiba N300 HDD 12TB at 549,99 €, or 45,83 € per TB.
Spindle speed
Both turn at 7200 RPM. Spindle speed sets how quickly the head reaches data and how much power and noise the drive makes, and at an identical RPM the two land in the same place on all of it.
Cache
Seagate SkyHawk AI 12TB carries 256 MB of onboard cache and Toshiba N300 HDD 12TB carries 256 MB — the buffer the drive uses to absorb bursts of writes and hold recently read data, smoothing over the mechanical delay of moving the head. More cache helps most under bursty, mixed workloads; for one long sequential transfer it barely matters.
Warranty
Seagate SkyHawk AI 12TB carries a 5-year warranty and Toshiba N300 HDD 12TB a 3-year one — how long the maker will replace a failed drive, and a rough read on the confidence it has in the mechanism.
