Samsung launches 8TB NVMe solid state drive in NF1 form factor

  1. Samsung Electronics has launched the largest capacity NVMe solid state drive to date. The 8TB NF1 SSD will target data-focused analytics and virtualization requirements within data centers.

    Even though this SSD is going to be fast and have a high capacity, its unique feature is being physically small. Otherwise known as Next-generation Small Form Factor (NGSFF), NF1 is a minuscule form factor measuring in at 11cm by 3.05cm that allows for three times the storage density of M.2.

    Samsung's new SSD runs on 16 pieces of 512GB NAND. Each chip has 16 layers of 256 gigabit V-NAND with 3-bits per cell. This increase in capacity allows for up to 576TB of storage to be put into 2U rack servers.

    In terms of performance, the 8TB SSD runs on the NVMe 1.3 protocol and has support for PCIe 4.0. Sequential read speeds approach 3,100 MB/s while write speeds are around 2,000 MB/s. Random reads are rated at 500,000 IOPS with random writes rated at 50,000 IOPS. In order to handle data-intensive tasks, 12GB of LPDDR4 DRAM is used as temporary cache space.

    As with any application requiring mass numbers of read and write operations, durability is rightfully a concern. Samsung believes this drive will have no problem handling extremely demanding tasks and states that this SSD can withstand 1.3 drive writes per day, equating to more than 10TB of writes daily for the three year warranty period.

    In the second half of this year, Samsung is planning to launch another similar SSD utilizing 512 gigabit V-NAND cells instead of the current 256 gigabit chips.

  2. Awesome. I look forward to a much smaller pc with excellent speed and storage.

    This sounds suspicious. So if you are a video editor, and try to copy a raw 8K video clip of 500GB, how will those 12GB of cache help? Or will the performance just drop to the ground?

    By the way, 90 minutes of raw 8K video on average is a 1.8TB file.

    I would imagine that CPU/GPU power would be more of a limiting factor than drive or cache speed.

    I am more curious about the needed cooling capacity of these, especially if you have your board fully populated? I've got an old industrial fan here that I can make a V shaped collar, but at high speed I'm a little worried about it sucking in all the chickens .......

    The cache is not meant for big files like that, it is meant for multiple 1-2GB file writes in a row. Something that big is not going to be dependent on things like cache or IOPS, but sustained write speeds, and SSD cooling, CPU power, and memory bandwidth will be more important. .

    The cache is not for user data, it's for the NAND mapping table.
    Just like on any other SSD. (Most SSD's require ca 1GB of DRAM per 1TB of NAND).

    I’m more interested in the price....

    Also when if ever will NF1 be available on desktop/workstation boards?

    Oh, that's easy to solve. You just take your desktop, head out to the end of an ocean pier and throw it in.

    Hey look, if it works for an M$ data center, it should work for you...(y)
