Seagate has officially updated their
FireCuda line, the solid-state supported, high-capacity hybrid drives. The new, 5th Gen models sport a thinner form-factor (2.5"), rocking the company's multi-tier cache technology as well as 1 TB SMR (Shingled Magnetic Recording) plates. The SMR plate's difference compared to conventional, perpendicular recording HDD technology allows these hybrid drives to increase storage density by up to 25%, by allowing newly-written magnetic tracks to partly overlap previously-written ones, reducing the amount of platter real-estate occupied.
The caveat with this technology is that the overlapping-tracks architecture may slow down the writing process, since writing to one track overwrites adjacent tracks, and requires them to be rewritten as well. However, according to Seagate, the large, multi-tier cache technology and large NAND caches are enough to offset any performance loss incurred by the SMR technology employed on these drives, and then some.
