Question SSD Performance question.

[billbo1970]

OK, first off let me apologize for the blurry pics. I'm getting older and taking a photo of my monitor so combined with shaky hands it's not the best, but you can make it out LOL.

I ran CrystalDisk Mark8 on my laptop pre and post SSD swap. I went from a Samsung 860 EVO to a PNY CS900. The new PNY reads slower than the old Samsung (especially that 2nd counter/test), but it writes significantly faster except for the last two counters. Which drive is better overall for a non-gaming laptop used for work (making web pages, using photoshop, etc etc)? I don't know what the differences are between these rows... Will these slower read speeds be noticeable? Will the faster write speeds be noticeable?

I doubt that you'll notice any difference. My experience is that SSD speed numbers, especially sequential read/write, tend to look a lot more impressive than real world results can back up. I have one box with a 10x spread in sequential read/write speeds (SATA on one hand, high end PCIe 4.0 NVMe on the other) and it's almost impossible to tell which drive I'm working with doing interactive stuff. I can tell when I run an hour-long test run, where the fast drive saves a few minutes, but not interactively.

Thanks for the reply Do you know what the different rows mean?

Do you know what the different rows mean?

It's the queue depth and size of data.

Lower rows are random and upper are sequential data.

Sequential is when you copy a single file. 4K random is what mostly happens when applications access files and read or write data. Increase depth from Q1 to anything more and you are measuring how well the SSD handles multitasking file operations. In other words, how well it responds to getting hammered. Lesser SSDs will see their higher queue depth performance suffer.

Windows key + Print Screen key.
The result will be in C:\Pictures\Screenshots
You got it from there

The Samsung will be faster in everyday use but by so little, you wouldn't notice.

That's unless you're also editing videos or other very large files which take a while to write, so you benefit from the faster write speed because you are waiting for the write to complete. Even then, you might have CPU or GPU (encode/decode) bottlenecks instead so you never notice the difference.

You do realize that you can press the keyboard Print Screen key, or <alt> <Print Screen> for only the window (app) in focus, then save that in an image editing app and have a perfect screenshot pic instead of blurry?

Yeah I know that, but that "screenshot" would be gone after swapping to the newly cloned drive bro... LOL

Thanks for the detailed answer Mindless1. I don't do much video editing, but I do a lot of photoshop for my website. On paper the PNY showed it was faster than the samsung, but that doesn't really seem to be the case, it's kind of a mixed bag :/. I bought the 2nd SSD so I can periodically clone the drive and then only need to swap out when a catastrophic failure eventually occurs. I wanted to put the faster drive in the laptop. Since it's a mixed bag, I put the newer one (the PNY) in, and the Samsung will be for cloning backups.

Yeah I know how to screenshot bro, but that image would be gone after swapping to the newly cloned drive... LOL
