Seagate predstavlja FireCuda SSHD-ove 5. generacije - do 2 TB, 8Gb NAND



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.

Svrha ove tehnologije je da arhitektura preklapajućih pjesama može usporiti proces pisanja, jer pisanje u jedan zapis prepisuje susjedne zapise, pa zahtijeva i njihovo prepisivanje. Međutim, prema Seagateu, velika, višeslojna tehnologija predmemoriranja i velika NAND predmemorija dovoljni su za nadoknadu gubitaka u performansama nastalih SMR tehnologijom koja se koristi na tim pogonima, a zatim i nekim.

Nova FireCuda linija nudit će prostor za pohranu od 500 Gb, 1 TB i 2 TB, donoseći kompatibilnost sa širim rasponom uređaja zahvaljujući smanjenoj z-visini od 7 mm. Sadrže 5400 RPM brzine vretena, dolazi sa 128 MB DRAM predmemorije predmemorije. Maksimalna brzina prijenosa i prosječna latencija za FireCuda 2,5 'ocjenjuju na 140 MB / s odnosno 5,6 ms, pri čemu se svi kapaciteti isporučuju s istom količinom DRAM cache memorije i 8 GB MLC NAND cache-a, što djeluje zamjenom često korištenih podaci u bržu NAND memoriju. Pogoni podupiru SATA 6 Gb / s protokol, s potrošnjom električne energije na 0,45 W u praznom hodu, 1,6 / 1,7 W snage čitanja / pisanja za pogone od 500 GB i 1 TB i 0,5 W u praznom hodu, 1,7 / 1,8 W snage čitanja / pisanja za njihovu braću od 2 TB.

While shipping of the drives is already underway, official prices or market availability dates still haven't been disclosed. However, the 2 TB model is reportedly going to cost around $100. The five-year warranty that Seagate offers on their FireCuda line of hybrid drives are sure to bring more value to the table, being longer than the standard 2-year on Seagate's family of Barracuda consumer HDDs.
