Samsung's NF1 NVMe hard drive looks like an M.2 interface, but it is not, it is NGSFF specifications, 3.05 cm wide, 11 cm long, a bit wider than the M.2 22110 hard drive, mainly for the data center market, replacing The traditional 2.5-inch NVMe hard disk, ultra-small size can be inserted in the 2U rack 72 8TB hard drive, composed of 576TB hard disk array, which is the world's largest capacity 2U disk array.
The maximum 8TB capacity requires 16 512GB flash memories, and each flash internal has 16 NAND chips with 256Gb core capacity, the TLC type. In addition to the 8TB capacity, the NF1 NVMe hard disk is also equipped with 12GB LPDDR4 memory for caching.
The NF1 SSD uses Samsung's new high-performance master, supports the NVMe 1.3 specification, and also supports the PCIe 4.0 specification. If this is true, this should be the world's first SSD host that supports PCIe 4.0.
Performance, NF1 NVMe hard drive read speed up to 3000MB / s, write speed 2000MB / s, random read 500K, random write 50K, the overall performance of continuous read and write and random read are good, but random write Into 50K performance is not high, but the composition of the 2U disk array can still bring millions of IOPS performance.
In terms of reliability, the NF1 NVMe hard disk supports 1.3 DWPD. During the three-year warranty period, it supports a total of 8 terabytes of data written 1.3 times per day.
From the perspective of the core capacity of only 256Gb, the current 8TB hard drive is not the final body, so Samsung also plans to introduce 512Gb core capacity NF1 hard drives in the second half of the year, and the capacity will theoretically double to 16TB.
