Phison has introduced its Pascari D205V datacenter SSD with a capacity of up to 128TB and a PCIe 5.0 x4 interface. The drive is aimed at AI training as well as media streaming applications that demand both high capacity and high performance. In an email Tom's Hardware received, Phison said the SSD will be available in the second quarter of next year and its clients can use the platform to build their own drives.

Phison's Pascari D205V datacenter SSD with 128TB of raw NAND memory (which provides a capacity of 122.88TB) is based on the Phison X2 controller and 2Tb 3D QLC NAND devices. The drive promises a sequential read speed of up to 14,600 MB/s and a sequential write speed of up to 3,200 MB/s as well as a random read performance of 3,000K 4K IOPS and 35K random write 16K IOPS, which makes it one of the fastest enterprise-grade SSD in the world and the fastest 120TB-class SSD in the industry. The platform is rated for 0.3 drive writes per day.

The new Pascari D205V has a PCIe 5.0 x4 single port interface or two PCIe 5.0 x2 dual port interfaces. Also, the model has power loss protection.

The Pascari D205V datacenter SSD is compatible with the latest servers supporting a PCIe 5.0 interface and can offer unprecedented performance while storing up to 2.2PB of data in a standard server with 24 drives. Yet, since Phison does not disclose the power consumption of its Pascari D205V SSD, it is impossible to say whether this product is drop-in compatible with all of the existing servers.

Phison's Pascari D205V drives in U.2 and E3.L form factors are available for preorder now and are expected to ship in early Q2 2025.

Phison is generally known as a leading developer of SSD controllers and platforms for client (some of the best consumer SSDs use Phison's controllers), embedded, and enterprise drives. The company's technology powers SSDs from major brands and controls a sizeable market share. But this year the company decided to go further and introduce Pascari: its own brand for enterprise-grade SSDs.

By developing its own reference drives for datacenters, Phison enables enterprises that want to adopt the latest storage technology to get it directly from the renowned developer of SSD platforms - instead of waiting for branded makers of solid-state drives to roll out their solutions based on the same controller.

"With the acceleration in AI training and data-intensive workloads there has been a tangible shift to a future-forward focus on storage as a critical component in capturing necessary volume to support data quality and integrity," said Michael Wu, General Manager and President, of Phison US. "With today's launch, each drive maximizes capacity while reducing power, space, and cooling constraints to minimize bottlenecks for transformative use cases. Customers can essentially push past previous infrastructure barriers to continue to scale as the market demands."

    Interesting, but as a consumer (and photographer) who likes all my images on one drive and backed up to other single drives, I would like 8TB drives to be cheaper (as expected for years now) and by now, for 12 and 16 TB drives to be available and even common. Right now, I'm filling 6.3 TB on my 8TB main data (PCIs 4 M.2) drive on my PC Motherboard. I am backing up to 8TB internal and external SATA SSDs. No spinners in my life now and absolutely no RAID or any type of stack or array. No way.... I want single drives with it all on there - main and backups.
    I would buy five 10TB PCIE 4 M.2 SSDs right now if I could, and I would expect them to be around 400 bucks each by now.
    But I guess I'm still dreaming.

    For a thought experiment, lets examine the potential of AI training that use high speed storage in place of memory. This is credible because AI training is bottlenecked by bandwidth - not latency, and SSD speed is growing leaps and bounds. First, a 8hi stack of HBM3e has 1.2TB/s bandwidth and Nvidia B200 has 8 of those. This resulted in 9.6TB/s aggregated bandwidth, which appears to be tall order for SSD. Now a speedy Pcie 5.0 x4 SSD has arround 15GB/s, so we need 9.6*1000/15=640 SSDs work in parallel to match HBM solution. This number is reduced to 320 SSDs if we use to Pcie 6.0 (160 for pcie 7.0 and 80 for 8.0) and requires a total of 1280 pcie lanes.

    Nand flash technology begins to outpace the interface it uses to connect. The main issue is shifting to Pcie not providing enough bandwidth, a direct result of the PCI-SIG being caught offguard by the AI boom. We may need a new interface pretty soon for the ever growing AI storage bandwidth need.

    Please don't back up anything you plan to keep to an SSD for long term storage. It's fine if it is in a system. But your post seems to indicate you plan on archiving things to SSDs and storing them offline for later use. SSDs lose charge in about 3-12 months without being powered on and refreshed. They are a very poor choice for long term archival storage.

    and if you think your ssd does not need to be defragged ....You are not in my league.
