How to Use CrystalDiskInfo

[@JM-ql7mh]

Great video Glenn, thank you. Sent this to a lesser experienced friend and it was just what he needed. Appreciate it.

[@GlennBerrySQL]

Great! I'm glad it was useful.

[@harrievangeffen]

I really hoped you would explain the advanced information, like what the values under C5 and C6 actually mean.

[@paquitoperez2116]

I was hoping for that too actually... maybe in another video. Thanx anyhow ;-)

[@GlennBerrySQL]

Thanks for the comment! CrystalDiskInfo (CDI) is mainly useful for spelunking into local drives to get detailed information about the model number, interface, firmware version, etc.. It also gives you their S.M.A.R.T. diagnostic information. If you have a logical drive with some RAID level, CrystalDiskInfo doesn't really expose anything useful. Your NAS or RAID management software should expose some information about the physical drives. You could temporarily pull a drive to check with CDI. CrystalDiskMark (CDM) will give you good sanity check performance information on a logical drive or a standalone physical drive. Those CDM numbers you posted seem quite low for four magnetic drives in RAID 5 (for sequential performance). Are you sure you have a 10GbE link and not a 1GbE link to the NAS? A single 14TB WD RED Pro drive should be able to do about 180-200 MB/s for reads and writes.

@@ChorizoBerry Any other tools you recommend for troubleshoots that I should have installed on my pc? honestly I normally skim through most videos but I really liked your explanation, you very good at teaching. I'm already using Crystaldisk thanks to you. I'm about to purchase an external SSD for video editing work and I wanted to compare the speeds and so much more so these videos explained everything soo well.

[@GlennBerrySQL]

Thanks for the sub!

[@asadfarraj]

Hi, I have a "ST2000LM007-1R8174 : 2000.3 GB" HDD, and in the "Read error rate" field, my 'Current' is 83 while my worst is '63'. The bubble next to it is blue, so maybe it's not failing anytime soon I hope. But are these numbers good or bad? The power on count and hours are 2524 & 2952 respectively. I have another HDD where the read error rate is 100 for both current and worst. That one's new, so I'm guessing 83 means the life has gone down? I just want some context on how concerned I should be.

[@kevinHSP000]

[@BadWeatherfreak]

So I have a msi B550m Bazooka motherboard and I have a corsair m600 lpx 2 tb in the main m.2 slot. On the transfer mode it says PCIe3.0 x4/ PCIe 4.0 x4. How do I know the speeds that the drive is operating and what the PCIe version?

[@GlennBerrySQL]

If you hover your mouse cursor over the Transfer Mode text box in Crystall Disk Info, it shows that the left-hand value is the "Current Mode" and the right-hand value is the "Supported Mode". That means that your drive and the M.2 slot it is in should support PCIe 4.0, but it is running in PCIe 3.0 mode. The most likely reason for that is the CPU you are using. For example, if you have a Ryzen 5 5600G "Cezanne", it only supports PCIe 3.0, no matter what the drive or M.2 slot support.

[@BadWeatherfreak]

@@GlennBerrySQL I am using a 5600g..

[@GlennBerrySQL]

@@BadWeatherfreak Well, there you go. That CPU only supports PCIe 3.0. You probably won't notice any difference for most typical daily activity. Sequential throughput is not a bottleneck for most things.

[@BadWeatherfreak]

@@GlennBerrySQL thanks

[@JohnWolf926]

Good day, my reallocated sectors count is 94 and my current pending sector count is 100, both in yellow and everything else is blue. How bad are these numbers in terms of urgency? Thank you in advance if you are still explaining to us 🙏

[@GlennBerrySQL]

I don't think those numbers are critical yet.

[@JohnWolf926]

@@GlennBerrySQL thank you sir

[@Camelotsmoon]

I swear I can't find this answer anywhere online: I take it that it doesn't work this way, but if you have a PCIE gen 4 x4 NVME SSD, and you have a PCIE gen 3 x8 slot (using one of those NVME to PCIE slot adapters), will that give you the same speed? Or will it just use PCIE Gen 3 x4? I know there are PCIE gen 3/4 x8 drives out there, but they're just overpriced lol.

[@GlennBerrySQL]

The PCIe specification is not forward compatible. If you plug a Gen 4 device into a Gen 3 slot (whether there is an adapter or not), it will fall back to Gen 3 x4 behavior. This is most noticeable with sequential performance. The drive only has four Gen 4 PCIe lanes, that will fall back to Gen 3.

[@BitsOfTruth]

Why does it have power on hours listed toward bottom again? Thanks.

[@GlennBerrySQL]

You would have to ask the software developer about that.

[@BitsOfTruth]

@@GlennBerrySQL I see. Thanks. I just often wondered.

[@BMLaminates]

Thanks for this. Do you know what Caution means on a Hdd?

[@asadfarraj]

It means the drive is having problems, and while it might not fail soon, you should still make backups as soon as possible.

[@ozymandias2k]

Hi Glenn Any idea why it doesn't show Total Host Writes on certain drives? Also I have a SSD PC SN520 NVMe WDC 256GB that the manufacturer states that it's 200 TBW. It shows 16 TB Total Host Writes but yet health status is only 79%. Any idea how reliable the Health Status monitor is?

[@GlennBerrySQL]

I don't know the answer to either of your questions. That would be a better question to the software author. You might try using the WD Drive Utilities to see what it shows. support.wdc.com/downloads.aspx

[@blainecovert8374]

Thanks for this clear & helpful video. I installed the Crystaldiskmark after watching your other one. Still trying to understand the usefull figures on that one for videographer use.

[@jimchallender4616]

Does this app work with and provide External SSD Temp etc.? What do you think of 2TB Samsung 970 EVO M.2 NVMe SSD?

[@GlennBerrySQL]

This utility will work with any drive that shows up with a drive letter in Windows. With external drives that have a USB connection, it may only show information about the USB controller on the drive. The 2TB Samsung 970 EVO is a good PCIe 3.0 drive, which has been replaced by the slightly better 970 EVO Plus.

[@beni__gabor]

06:32 Can I keep this program always run in background? Does it write continuously in my SSD like a disk benchmark? Thanks, very nice video

[@GlennBerrySQL]

You can run this continuously and it won't hurt anything. I'm not sure why you would want to do that though. Most people just periodically check their drives with this tool.

[@reyasadulhasan]

Reinstall of windows will erase the SSD usage duration data?

[@GlennBerrySQL]

No. The SSD tracks its usage data, not the OS

[@earthhalienn1799]

Alarm goes off ...I don't see anything obvious wrong with my drives. Event log is turned on ...but where the hell is the event log at!!!! No option that I can find to view it! can't find it at the install location?

[@frankenstein3163]

I thought ssd was more thermal resistant.. good to know. I do know mechanical drives suffer if they get to cold all the time. Would you say that sata ssd can have more wrights than the NVMe ssd ? I was hoping for explaining what the current/worst/threshold meaning's more in detail. Like how can the threshold be lower than the other numbers on "Read Error Rate" same with relocated sectors count

[@GlennBerrySQL]

The write endurance depends on the type of NAND cells that the SSDs uses.

[@jeettrivedii]

Mine shows 90%. Is that good? Or should I replace it? Another thing, what should be considered as normal temperature?

[@GlennBerrySQL]

That means you have 90% of the life remaining. Why would you replace it now? There is no reason to do that.

[@xXJogratXx]

Mine says Disk not found even though I can see both of my drives in files explorer. How can I fix this? I'm using: 1TB XPG SX8200 Pro as boot drive and 2TB Seagate Barracuda as extra storage

[@GlennBerrySQL]

Does it see either of your two drives? Are you using the latest version of CrystalDiskInfo?

[@xXJogratXx]

@@GlennBerrySQL It doesn't see any of my drives. I have the latest version of CrystalDiskInfo as well.

[@GlennBerrySQL]

@@xXJogratXx I'm not sure what to tell you, beyond doing some basic troubleshooting. If Windows can see the drives, they are obviously present and functioning. You might try using another utility like HWiNFO64 to look at your drives. www.hwinfo.com/download/
