I just want to say you did a great job of the breakdowns, it gave me a lot of info, I also like that you broke up the video and let people know they can quit watching if that's all they are looking for, great video man!
Measure time is how long should it be measured for. I like 30 seconds for a more realistic load. Interval time is the time between tests. I like to do 60 seconds because it gives the drive and OS some time to settle before going into the next test.
I rolled my eyes at the little faces. and then now I'm laughing my butt off. I've seen your videos pop up a lot so it's time I subscribe. Very informative and to the point videos!
Excellent video dude. Wonderfully described. If you would like to expand on it you could talk about real world use representation of numbers, and if that's possible. Cheers
I think you need to create part 2 of this video to explain where these theorical concepts are put into perspective with real world usage like Operating system operation, gaming, winrar, etc.
Great vid with Great presentation. Thanks for the time & effort put into this. I totally agree with most of the comments here as I've used this b4 but been too lazy to go into any depth of understanding the results. Now I do understand so much better I will check my drives again. Ray D.
Liked for the whimsical faces :D Honestly, thanks for the guide! I just picked up a gen 4 nvme upgrade for my Galaxy Flex2 Alpha over the gen 3 currently installed. Just waiting on backups now :D Interesting to see what kind of performance I'll pick up.
Update on the upgrade: nearly every type of test shows consistent improvements being close to or at advertised read/write speeds. I've noticed things are a lot more snappy, and I've also noticed that GTA 5 w/mods can play happily without the occasional stuttering as before. I went from a Western Digital PCIe 3 512GB NVMe up to a PCIe 4 Samsung 980 Pro.
I appreciate the time and effort that you put into this to VERY detailed tutorial! Definitely good insight and information that I always wanted to know, but never really got around to looking up, but this vid gives me it all! #MorePOOOOOOOOOOWERRRR 😈
I'm trying to determine if my system drive is nvme or not. The laptop is old and was given to me by a friend and he doesn't remember. I ran CDM twice, once with nvme SSD selected and once without. Results were pretty much the same, about 2 mb/s faster on the Default setting.
1 GiB is one GIBIBYTE. Similarly a KiB is a Kibibyte and MiB is a Mebibyte. This usage is a more accurate description of the number of bytes, or at least a not-inaccurate one. We think of a kilobyte as being 1024 bytes, but actually that doesn't really make sense since kilo means 1000. The more you know 🌠🌈
Thanks Steve! It’s exact and let’s also talk about Windows showing « GB » for drives free space when it’s actually Gibibytes by looking in disk’s properties.
I thought this was explained pretty po orly. A “Ki *lo* byte” is equal to 1000 bytes, but a “Ki *bi* byte” is equal to 1024 bytes. The same thing occurs with bigger numbers, the “bi” will always mean 1024* of the previous size, while the metric version obviously means 1000. To address the comment below; windows will show storage size in mebibytes, but will incorrectly label it as megabytes. So if you see your 1TB drive saying it’s only 931GB, that’s normal, and just means windows is stupid, because it for got the “i” in “GiB”. But I’m not sure why they calculate it in GiB anyways.
I was going to say that this video is very helpful, but the one thing it's missing is the method to get cool manga girl images on it...but you even showed that in the video! (By the way, you said that you're learning as well and asked for any constructive input, so I'll just say that GB is "gigabyte", but GiB is "gibibyte", which is binary-based and is a little bit larger than a gigabyte.) Thanks again for the info!
Thank you very much for this video. But I don't understand why there is not a software wicho could just translate those numbers to say to the user : "ok your hard drive is fine or not".
Something to know that you won't hear any Affiliated videos is that the results also depends on your system. Some systems will be different so don't expect to get the same numbers you see in the videos.
I'm guessing measure time is how often the performance is measured. I see it as, you have a sensor on a water pipe and you measure the pressure of the water every "measure time" seconds if that makes sense. But I could be wrong. @TravisNewton1 had a different idea.
Im very new to this so I understand very little. I used this benchmark on the family desktop and row 1 was 161mb and row 2 was 183mb. I thought that row 1 is the theorietical best and the second row is what it will reasonably do. Its worth noting the desktop uses a hdd
I have a few question, does the space of storage affect the test result ? If I choose another storage partition with more space of storage than the other, is it gonna represent the result of my storage device or it just represent the result of that partition ? Anyway, great video !
Hey, great video - thanks for making it! Question - I have been having trouble downloading games from Steam lately. I keep getting a "download paused, disk write error" message. I downloaded this software and ran the test, and the bottom 2 in the write column came back with zeros. I have a Sandisk Ultra II SSD. I'm thinking this indicates a problem with my disk. What do you think?
@@TechIlliterate Hey, thank you for the response! It is not my primary drive - it is a drive I added for extra storage for games, music, etc. My OS is on a different drive. I guess my real question is - if those tests come back with zeroes in the bottom right two columns (my settings were at 5/32gb, if that makes sense to you), does that indicate that I likely have a problem? In any case, you have my sub. Thank you for making videos like this, and for being responsive!
@@Rsivordog It seems like there is a problem but that doesn't necessarily mean the drive is broken. Could be any number of things. Personally I would start with CHCKDSK in the command prompt, re-plug the SATA cable and check for malware. Thanks!
amazing vid, i have just brought a new WD SN550 500GB SSD and crystaldiskmark 8's SEQ1M Q8T1's result for my SSD is around 1600 MB/s which is very low compared to 2400 MB/s as advertised by Western Digital, should I return my drive and replace with another one or this normal?
So in the hunt for the biggest bottleneck on any gaming PC can we say that it is not the GPU or the CPU or the RAM or the storage ssd, but actually the queue depth being used? Regardless of sequential or random IOPS, basically the MUCH lower queue depth is the liming factor here right? Why not just pump that number up if nvme ssds support higher queue depths. The lower the QD the less any SSD can use its full potential right? What exactly determines QD on a consumer PC? CPU? RAM? Motherboard? The operating system?
