Samsung Introduces 8TB SSD In NF1 Form Factor
Samsung Electronics Co., Ltd. launched the highest capacity Next-generation Small Form Factor (NGSFF), an 8TB NF1 SSD. Designed for the data center, the new 8TB NF1 SSD is optimized for data-intensive analytics and virtualization applications. The company goes on to state that customers can put up to 72 NF1 drives in a 2U space and with 8TB can hit density of 576TB.
In order to hit the 8TB mark in a 11cm x 3.05cm footprint, Samsung built the new SSDs with 16 of its 512GB NAND packages, each of which was stacked in 16 layers of 256Gb 3-bit V-NAND chips. This doubles the capacity of the common M.2 form factor (though it has a slightly larger footprint as M.2 is 11cm x 2.2cm) used in hyper-scale servers and ultra-slim mobile devices. Samsung believes that the NF1 SSDs can replace 2.5” NVMe SSDs as they can greatly increase density in the same form factor.
Increases in density are a great feature to bring, but users want either the same or better performance before they go out and start yanking the old drives out. Samsung is also featuring a brand new, high-performance controller in the NF1 SSD. The controller supports the NVMe 1.3 protocol and PCIe 4.0 interface, delivering sequential read speeds of 3,100MB/s and write speeds of 2,000MB/s and random speeds of 500K IOPS read and 50K IOPS write. Samsung states that leveraging the NF1 SSSs in an enterprise server can hit over 1 million IOPS in a 2U footprint. The NF1 also includes a 12GB LPDDR4 DRAM to enable faster and more energy-efficient data processing.
On the endurance side of things, Samsung states that its NF1 NVMe SSD can hit 1.3 DWPD, or the ability to write 8TB of data 1.3 times a day for its 3-year warranty period. Later this year, the company will accompany its 256Gb 3-bit V-NAND-based SSD with a 512Gb version to accommodate, what it states as, even faster processing for big data applications, while also accelerating the growth in next-generation enterprise and mid-market data centers
