Samsung presenta un SSD da oltre 30 TB di capienza

Samsung presenta un SSD da oltre 30 TB di capienza

La società sudcoreana toglie ufficialmente il velo da un'unità a stato solido alla quale i tecnici stavano lavorando da circa un anno e mezzo.

Già un anno e mezzo fa Samsung aveva annunciato lo sviluppo di un SSD a elevata capacità da circa 32 TB: il PM1643.
Finalmente la società sudcoreana ha tolto il velo dalla sua unità a stato solido “da guinness” svelandone tutte le principali caratteristiche.

Chi acquisterà questo monster-SSD potrà memorizzare fino a 30,72 TB di dati. L’unità, da 2,5 pollici, sfrutta l’interfaccia SAS, a sottolineare quanto si tratti di un device “per pochi eletti” e congegnato per le imprese.


Samsung PM1643 utilizza 32 package di memoria NAND da 1 TB ciascuno; ognuno consiste di chip V-NAND realizzati in tecnologia TLC a 64 livelli da 512 Gbit.
Per ottimizzare al massimo la parallelizzazione durante l’accesso ai dati, l’SSD monta ben 40 GB di memoria DRAM DDR4, distribuiti in dieci package da 4 GB collegati ricorrendo a una connessione Through Silicon Via (TSV).

Sul versante prestazionale, PM1643 – grazie anche all’interfaccia SAS da 12 Gbps – raggiunge 2.100 MB/s e 1.700 MB/s in lettura e scrittura sequenziale; 400.000 e 50.000 IOPS, rispettivamente, in lettura e scrittura random 4K.
Si tratta quindi di un’unità particolarmente adatta per le attività di lettura dei dati più intensive, in special modo quando si ha a che fare con file di piccole dimensioni.

Samsung garantisce la completa riscrittura del contenuto dell’SSD a cadenza giornaliera per cinque anni prima che possano iniziare a presentarsi dei problemi.

Samsung PM1643 non è ovviamente un SSD che si troverà in vendita su Amazon ma dalla società asiatica si fa sapere che nella stessa serie saranno previsti “tagli” da 15,36 TB, 7,68 TB, 3,84 TB, 1,92 TB, 960 GB e 800 GB.
