I recently put together a new PC and everything is running smoothly, except for one thing that's been bothering me: the benchmark results for my Samsung 990 Pro 2 TB m.2 SSD using Samsung Magician. I'm not very savvy when it comes to SSDs, and I'm confused about the 'random write' speed since it seems significantly lower than expected. I have made sure the SSD is in the correct M.2 slot, and both the firmware and software are updated. It's the only drive with Windows 11 on it, and I even tried running it in Full Performance Mode without much change—just that pesky random write speed still being low. Can anyone shed some light on why this might be happening or if it's even worth worrying about? Here's my benchmark result: [https://imgur.com/a/uJ0TqRU](https://imgur.com/a/uJ0TqRU).

Also, how full is your SSD? Performance can drop significantly once it’s got a lot of data on it. It’s a good idea to ensure you have a clean installation of Windows and disconnect from the internet before running the tests for more accurate results.
Did you consider testing with different software? It might give you a broader view of the SSD performance. I also noticed that the Samsung benchmark shows lower random write speeds compared to sequential read/writes, but that can be pretty normal for SSDs. Have you run any tests with CrystalDiskMark?
Honestly, those speeds seem common to me. Most SSD benchmarks typically highlight sequential read/write speeds, which are quicker because the drive can access memory addresses in order. When it comes to random read/writes, the drives take longer because they have to locate the memory addresses, hence the slower speed you noticed.
But isn't the random write speed supposed to be around 1,550K? That's definitely lower than what I expected.
You're good, man! For context, random write speeds generally aren't as impressive as sequential speeds, so not to worry. Just check the specs and make sure you're hitting those sequential write rates as they demonstrate the drive's overall performance.
Yeah, I tried it but I'm really not sure what the results mean. The Samsung test definitely shows a low score for random writes, and the results I found from CrystalDiskMark seem all over the map, which adds to my confusion.
