Samsung Electronics ha annunciato di recente la nuova linea di drive a stato solido con interfaccia SATA 6Gbps denominata 870 QVO. Queste unità sono dedicate al mercato consumer, e possono vantare la dotazione di memorie NAND flash di tipo quad-level cell (QLC) a 4 bit, e una capacità di memorizzazione che può raggiungere anche gli 8TB.
Tra i componenti alla base degli SSD 870 QVO sono certamente degni di nota il controller proprietario Samsung MKX e la memoria DRAM di tipo LPDDR4 con capacità pari a 8GB, 4GB, 2GB e 1GB in corrispondenza dei drive con capacità pari rispettivamente a 8TB, 4TB, 2TB e 1TB.
In accordo al produttore, gli SSD 870 QVO sono quindi in grado di colmare anche l'unico divario a sfavore esistente con le unità di tipo HDD, coincidente proprio con la capacità di memorizzazione, fermo restando che restano inalterati i vantaggi offerti dal punto di vista prestazionale.
Samsung afferma, inoltre, che i drive SSD 870 QVO possono vantare le velocità di scrittura e letture massime pari a 560MB/s e 530MB/s in modalità di accesso sequenziale, mentre in quello random il numero massimo di IOPS è pari a 98K (lettura) e a 88K (scrittura).
I drive SSD 870 sono stati commercializzati da Samsung il 30 giugno (2020): nel mercato statunitense la variante con capacità pari a 1TB costa $129.99.
Press Release
Samsung Electronics today introduced its second-generation quad-level cell (QLC) flash drive, the 870 QVO SATA SSD, that is setting a new standard for high-capacity consumer storage. Featuring an industry-leading capacity of up to eight terabytes (TB), the new SSD delivers an uncompromising mix of speed, storage capacity and reliability for mainstream and professional PC users.
In the past, consumers have had to choose between SSDs – which provide superior performance – and HDDs, which traditionally offer greater capacity. Samsung's 870 QVO SSD, however, is able to reliably offer the best of both worlds, making it an optimal choice for mainstream PC users who prioritize performance and value, as well as for professional users who require high levels of capacity.
"Following the launch of Samsung's first consumer QLC drive – the 860 QVO – in 2018, we are releasing our second-generation QVO SSD which offers doubled capacity of 8TB as well as enhanced performance and reliability," said Dr. Mike Mang, vice president of the Memory Brand Product Biz Team at Samsung Electronics. "The new 870 QVO will allow more consumers to enjoy the performance benefits of an SSD at HDD-like capacities."
The 870 QVO offers best-in-class sequential read and write speeds of up to 560 MB/s and 530 MB/s respectively, with the drive's Intelligent TurboWrite technology allowing it to maintain peak performance levels using a large variable SLC buffer. The 870 QVO also delivers a 13% improvement in random read speed compared to the 860 QVO, making it ideally suited for everyday computing needs such as multitasking, gaming and web browsing. The renewed Data Migration and Magician 6 softwares provide a host of improved and added features, enabling users to upgrade, manage and optimize their SSDs with greater ease.
In addition to the industry-leading capacity and performance, the 870 QVO provides an exceptional endurance rating of up to 2,880 terabytes written (TBW), or a three-year limited warranty.
The 870 QVO comes in 1TB, 2TB, 4TB and 8TB models, and will be available from June 30, 20206 with a manufacturer's suggested retail price starting at $129.99 for the 1TB model. To find out more, please visit samsung.com/ssd or samsungssd.com.
