I don't know if you could Spin Rite this, or if you could even hook it to a normal computer, but YouTube just recommended this video. 245 TERABYTE drive. This is news to me.

DNS Benchmark v2 is Finished and Available! Guest:
That's right. It took an entire year, but the result far more accurate and feature laden than we originally planned. The world now has a universal, multi-protocol, super-accurate, DNS resolver performance-measuring tool. This major second version is not free. But the deal is, purchase it once for $9.95 and you own it — and it's entire future — without ever being asked to pay anything more. For an overview list of features and more, please see The DNS Benchmark page at GRC. If you decide to make it your own, thanks in advance. It's a piece of work I'm proud to offer for sale. And if you should have any questions, many of the people who have been using and testing it throughout the past year often hang out here.

BootAble – FreeDOS boot testing freeware
To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.
GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.
The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.
You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Rhetorical question: What is the difference between an AI drive and just a drive? Does it decide whether I really want to write the data or not? Like, come-on, does everything have to be AI?
Aside from actually watching the video and seeing what Huawei says, let me Google that for us
Code:
Q: Google, What is the difference between the Huawei AI 245 terabyte drive and a non-AI drive?
A: The Huawei OceanDisk AI drives, such as the 245 TB LC 560, are designed to overcome data bottlenecks that hinder artificial intelligence (AI) training, while non-AI drives are general-purpose storage solutions not optimized for these specialized workloads.
Key differences lie in their performance, capacity, and the specific design features that make AI drives suited for the unique demands of AI data processing. [1, 2, 3, 4]
Performance and architecture
| Feature [1, 2, 5, 6, 7, 8, 9, 10] | Huawei OceanDisk AI Drive | Non-AI Drive (Traditional SSD/HDD) |
| --- | --- | --- |
| Purpose | Specifically engineered to eliminate performance and memory bottlenecks in AI training clusters. | Designed for general storage applications, such as running operating systems, business applications, or data archiving. |
| Efficiency | Improves AI data processing efficiency by up to 6.6 times by feeding massive datasets to GPUs faster. | Offers standard read/write speeds, which become a bottleneck when handling the large, rapid data movements required for AI training. |
| Memory optimization | Works with software like Huawei's Unified Cache Manager (UCM) to offload "key-value" cache data from a GPU's high-bandwidth memory (HBM) to the SSD. This reduces computation time and speeds up AI inference. | Lacks specialized software and hardware to manage the flow of cache data between the drive and a GPU's HBM. |
| IOPS and bandwidth | Achieves extremely high input/output operations per second (IOPS) and bandwidth to keep AI processors continuously fed with data and prevent them from idling. | While enterprise-grade SSDs offer fast IOPS, they are not optimized for the specific, sustained, and rapid I/O patterns of AI workloads. |
Capacity and density
| Feature [1, 2, 10, 11] | Huawei OceanDisk AI Drive | Non-AI Drive (Traditional SSD/HDD) |
| --- | --- | --- |
| Capacity | Offers industry-leading capacity, such as 245 terabytes per drive, to handle the "data explosion" from multimodal AI data. | The capacity is significantly smaller. Traditional high-capacity enterprise drives typically offer a fraction of this per-drive capacity. |
| Space utilization | A 245 TB drive dramatically increases storage density, allowing data centers to store massive datasets while cutting physical space requirements by over 85%. | Higher storage capacity would require a larger number of drives, leading to much greater physical space usage and energy consumption. |
The need for specialized AI drives
The development of specialized AI storage like Huawei's OceanDisk is a direct response to the "capacity wall" and "memory wall" that have emerged with the growth of AI models. These models are becoming multimodal and trillions of parameters large, requiring massive, high-speed storage to load training data efficiently. By building an SSD tailored to these demands, Huawei makes large-scale AI training more economically viable and efficient. [1, 2, 11, 12, 13]

It will get read boredom - waiting around with little to do
;-)

Yeah....wouldn't touch that ever. "Yes, Huawei remains subject to significant bans and restrictions in the US, preventing its equipment from being used in American networks and restricting U.S. companies from supplying components or software, including chips and the Android operating system, to Huawei due to national security concerns. "
I don't think of Huawei as a company like Seagate or one of those type of companies, I just thought it was interesting from a technology/engineering perspective that it is possible to fit that much capacity to basically normal-sized drive.
The price will be unbelievably low, but when you get it, inside you'll find a 64 GB drive with modded firmware.

Hahahahaha!
Even if AI out-smarts ValiDrive, SPINRITE LEVEL 5
will have it's way with THAT!
;-)
At peak 6 GB/s, it would take at least 2 1/3 days
for SpinRite to perform a Level 5 on 245 TB.
Considering that a 20 TB HDD takes me that long to
run a Level 5, an AI SSD would have to be very
very smart and fast indeed.
