How To Use CrystalDiskMark | What Do The Numbers Mean?

[@devondvorak9176]

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!

[@TravisNewton1]

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.

[@mkaia47]

i went for the shizaku edition, great edition

[@MaxNMotion]

Excellent tutorial. Wish all tutorials on YT were this useful and clear at the same time.

[@ismailv309]

I didn't know that Jonny Sins has a Tech page, dude is everywhere!

[@robertweekes5783]

I was really confused by the Crystal Disk Info... didn't realize it was a completely different (simpler) program. lol Very helpful !

[@jeffreymaugenest]

Thank you for putting this together in plain language. Appreciate all the effort you put into making this video.

[@zgagacz]

Great video! You spent time and effort to make the info clear and easy to understand, that's appreciated. Well done!

[@locant23]

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!

[@TurtleSauceGaming]

Yeah! Another cultured man using the cultured version of Cystal Disk

[@shinep_ag]

the developer is pretty based

[@rontarrant]

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.

[@RazorTeam]

yeah, great videos buddy.. greetings from Philippines.. great review.

[@satysin630]

A solid breakdown of CrystalDiskMark 👍

[@neilcarman6970]

this is hands down the funniest tech breakdown video i've seen, thank you

[@sany6006]

… aaaand now I can’t unsee the faces. Great video btw. 👍🏼

[@felipevellasco6526]

Thank you friend. You explained every bit of it perfectly. Exactly what I was looking for.

[@georgikukov5129]

Great video, straight to the point, with a little nugget of explanation boiled down to the essentials! Thanks!

[@Mainbusfail]

Dude, just because you shared the analogy of how threads, etc work. Got a Sub and Like. Thank you man.

[@k2000pvc]

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.

[@AlissonAraujoBR]

Thank you so much Nick. English is not my first language but you made this very easy to understand.

[@eskimo4130]

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

[@user-blabla-47854]

I hoped for more detailed explanation of technical details, like queues and threads.

[@Phelly2]

1:30 you fucked me up with this one. Windows will never be the same ever again.

[@taylor22222222]

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.

[@taylor22222222]

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.

[@TG-Maverick22]

Thank you so much for this explanation, greatly helped me. 5/5

[@user-kg4sx8hv2i]

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.

[@bananaorangeguy5277]

really enjoy listening to you explaining!

[@amincatallo]

Excellent explanation, i understood many things about the software that weren't clear to me.

[@DJizLurch]

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 😈

[@nicholasrosella2952]

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

[@controversialrebel5639]

[@Gamingcs11692]

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.

[@gb4939]

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".

I got a gen 4x4 advertising 7400MB/s read and write but after testing i barley got 3216.96 MB/S

[@TardlerDesigns]

i ran the same test on my C drive, 1st row 2029/1680, the 2nd row however is 1860/50? is something failing?

[@aksshaysharma96]

These how to Tutotia is amazing, as there is a dearth of such educatioin content on YT

[@mohammadalif4949]

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 !

[@RealKeytones]

I think the only time the space of storage would effect speed is when there isn’t enough room to fit the data. I could be wrong though

[@Random-yz8gb]

I have wd pc sn 730 and I am getting 2700 read and 500 write which is way lower than advertised what should I do

[@rodin0100]

my western digital an1500 1tb only shows 1600 mb/s while it's advertised for 6500.

[@jay6981]

nice explanation saitama! POWER!

[@lcvenusaur2168]

36 write speed when advertized is 450 :( what do i do??

[@OriginalAtomicSheep]

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.

[@Rsivordog]

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]

Definitely sounds like an issue with the disk. Is it your C: drive? Download a disk checking utility or use the command prompt.

[@Rsivordog]

@@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!

[@TechIlliterate]

@@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!

[@angrymidget4728]

"Just a smidge" Oh, will prolly be like, 40 or smth "at 65" Oh, cool so it's double *sips tea* "thousand" *pffft!!*

[@supernova-4420]

best explaination ive heard yet! and funny too xD

[@thesilentgeneration]

I went to the site and all I see to download is Retro. I downloaded what I thought was for Win 11, but when I run the app, I don't get the same interface that you show on your site. Also, I tried to remove it from my system, but it will not remove. I tried Revo uninstaller, but it didn't show up. I tried the usual Win 11 delete, but It just kept spinning. Furthermore, I tried File Shredder, but that did not work. What to do?

[@Ashok_Majhi]

This was a lot of helpful, Thank You

[@Anreii]

for some reason my second write speed is better than my first by a fair bit?... same when I retried it too lol.

[@aliservan7188]

Any idea how I test a network drive? Specifically a NAS?

[@edwardcastro6864]

thank you so my new friend,look forward to more videos.

[@noyanjaved4447]

great video man....underrated channel

[@JoeMurphysGuitarlessons]

Great video, can this be used to get info on transfer speeds between drives and pc memory cards etc ?

[@Rationalific]

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!

Hi there nice video, just one thing if the numbers are low could it be something other than the hdd/sdd like the cpu or ram chips for instance...they all have to work together....F in Uk

Thanks man this helped a lot!

[@NeuroPulse]

I would check your system before getting an RMA as I would expect it to be user error. For example some m.2 slots have a SATA mode.

[@lucaspoole8866]

If there drastically different then the manufacturers results consider getting a RMA??? What is a RMA?

[@TechIlliterate]

Basically an exchange from the manufacturer. It would be easier in many cases to return it to the store.

[@thegizmoguru]

Does someone know why the developers of this software caution users right below the download link that “CrystalDiskMark may shorten SSD/USB Memory life” ?

[@TechIlliterate]

Because flash memory has a finite amount of writes and using the software will use some of that life. Not to worry unless you plan to use it a lot. For example my 500gb samsung ssd has 28, 000GB in writes but still has 97% life. I've had it for 6 years.

[@Craze_Lifter]

thanks just found out my ssd was failing system was feeling way slower than usual and stuttering!!

[@theotherfaceof]

[@skygazer2678]

For some reason, my both gen3 ssd in my G15 5515 give me 1800s MB/s read speed instead of advertised 3200 to 3500 MB/s. If it was only one I could have thought its ssd fault but it happens with both the ssd. Actually three, if we count the Dell's own ssd which came with the laptop. Other two are Acer FA100 1TB and Crucial P3 1TB. Any help would be appreciated.

[@playeromaximo4382]

Can I test a new drive through a USB 3.0 enclosure (like a laptop) and still get accurate readings, or does the new drive need to be hooked up inside (in a desktop)?

[@TechIlliterate]

Yeah you can test via usb. You will be limited by the bandwidth but as long as the devices speed doesn't exceed then it's not an issue.

[@Jakob-W]

hey is it weird that my SSD puts out higher numbers on real world performance over peak? Also its a Sata SSD (Crucial MX500) rated to 500 MB/s but the benchmark says 7019.41 MB/s read

[@TechIlliterate]

That seems way off! Unless you have accidentally found a way to widen the SATA bandwidth.

[@CarlKahler]

What is close to the advertised speed my drive is advertised at 7300/6900 and is only 6400/6225 does that seem within the allowed?
