Hello fellow readers, in this article I will be providing a fix for Slow Write Speed issues on WD SN570 when using Steam/Epic Downloads and media transfers.

> ## Background <br>
## Background <br>
The advent of Host Memory Buffer on budget NVMe drives to give better write performance instead of adding DRAM on the drive. With HMB, SSD manufacturers can save on BOM costs and make the drive more compact to focus on higher storage size. As you are aware, most NVMe SSDs are available in [M.2](https://en.wikipedia.org/wiki/M.2) format with different sizes aka lengths i.e 30mm, 42mm and 80mm. There are few sizes used in enterprise SSDs optimized for more write endurance such as 60mm and 110mm.

With newer PCIe generation and the current version being PCIe 5.0 with x4 lanes promising sequential reads of 12GB/s and writes of 9GB/s.
As of 2023, you will see general availability is PCIe 4 with x4 lanes with reads of 7GB/s and 5GB/s writes. In thin and light laptops you will either see M.2 30 or 40mm with 4 lanes with HMB enabled.

Theoretically if HMB and firmware is implemented properly that can properly perform garbage collection and cleanup the write cache once the data is written to the flash media. Now, you will ask me what's the point of writing this article if all's good.
Let's take a look at affected drive i.e [WD SN570](https://www.techpowerup.com/ssd-specs/western-digital-sn570-1-tb.d467) which is a budget NVMe with HMB cache size of 64MB. HMB cache is different from [pseudo-SLC cache](https://sabrent.com/blogs/storage/slc-caching) which uses part of the capacity to be used as SLC cache for faster write performance. Usually bigger sizes have bigger SLC cache in essence, 1TB will have double the SLC cache of 512GB drive of the same manufacturer.

## What\'s the fix? <br>
What I can I say, I found a fix after constantly going around review articles and finally came across reddit posts that provided a fix when there was nothing listed in WD articles about the issue.

Hey, don't test our patience! We're literally pulling our hairs out and going bald.

### Well, that's all folks! Hope you enjoyed the article and simply brought smiles after seeing those huge improvement write speed on your SN570.
