Best SSD for Deep Learning (Data Science, Machine Learning)
5/5 - (13 votes)

There are many different types of SSDs (solid-state drives) on the market, but not all are created equal when it comes to deep learning. In this article, we’ll take a look at the best SSD for deep learning and data science so that you can make an informed decision when it comes to choosing the right storage for your needs.

Why Should Use SSD For Deep Learning or Machine Learning?

Artificial intelligence (AI) and machine learning (ML) use cases have multiplied over the past several years, regardless of whether you run a huge corporation with a multimillion-dollar data center or a tiny business with a few application servers in a server closet. The performance of NVMe SSDs has shown to be superior for these workloads.

Data center leaders have become more astute and efficient in how their IT infrastructure handles these highly transactional workloads in today’s hybrid environment. They utilize high-performance object storage infrastructures with data-hungry, next-generation applications running on NVMe SSDs to capture, store quickly, and analyze more data for users.

Therefore, designing a PC with the finest SSDs for Deep Learning computers has come. For your deep learning, machine learning (ML), and data science projects, we have examined more than a hundred hard drives and selected what we believe to be the top SSDs for every price range.

SSD vs. HDD: Which Is Better For Deep Learning?

SSD vs. HDD Which Is Better For Deep Learning

Our first stop is to talk about memory requirements for your entire workstation. When it comes to any kind of AI project, there will be a lot of data moving as you train your programs.

The various machine learning memory requirements are fairly complicated, but the idea of using SSD or HDD for machine learning is easy to tackle. As with most builds, it is probably best to have a bit of both.

For example: If you read your data from the drive as needed (blocking wait), then a 100 MB/s hard drive will take you about 185 milliseconds for an ImageNet 32 ​​mini-batch! However, suppose you asynchronously “fetch” (async) the data before it is used (e.g., torch vision loaders). In that case, you will load the mini-batch in 185 milliseconds, while the computation time for most deep neural networks on ImageNet is about 200 milliseconds. Therefore, you won’t face any performance damage since you load the next mini-batch while the current one is still processing.

There will be plenty of temporary data storage, and it will be incredibly convenient to have an SSD to migrate data as needed quickly. However, for data that won’t be moved frequently or will eventually land in a permanent storage situation, HDD will work just fine and be far cheaper.

If you are not using large datasets and instead plan on using simulations to train your AI program, then you may be able to bypass the need for a permanent storage solution like an HDD to save on expenses. So we recommend SSDs for comfort and greater productivity: Programs start and respond faster and pre-process large files a little faster. If you buy an NVMe SSD, you will get an even smoother experience than a regular SSD. Therefore, the ideal configuration is to have a large and slow hard drive for datasets and an SSD for performance and comfort.

If you want to know more about the differences between SSD and HDD for machine learning, we have a great blog post that better explores these differences.

An entry-level NVMe SSD with TLC NAND and a DRAMless controller is the SSD 980. It represents a brand-new product category for Samsung in the retail industry that it has never created before. This form of drive, with TLC and without DRAM, is already widely available on the market from other turn-key solution providers. This type of drive has been well-liked by OEMs since it enables them to advertise an NVMe SSD without paying the price of a high-end drive.

The “Pablo” controller serves as the foundation of the Samsung SSD 980. Although it has been available in the Samsung Portable SSD T7 family for more than a year, this isn’t a brand-new NVMe controller. This controller lacks a DRAM interface and has four NAND channels instead of the eight in Samsung’s high-end NVMe drives. The Pablo controller can saturate a PCIe 3.0 x4 host interface without using eight NAND channels because of the high NAND IO speeds allowed by current generations of 3D NAND.
