    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.

    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 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.

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!

    Does this program automatically delete the data it used to write the disk? or do you have to delete it manually after ??? I was playing Ratchet and Clank and saw that sometimes there was a short loading time like 2 or 3 seconds while jumping dimensions and other gameplay videos were super fluid and the dimension change was super fast, I have a very nice pc but I've heard they couldn't make this game for the ps4 because the game couldn't work right with the slow read speeds of magnetic disks so I went to check out my disks' speeds and it turns out my nvme has a read time 6 and a half times higher than the sata ssd I installed the game in. Also my newer ssd that's only a month old is giving me some weird numbers, during the first test it scored 12 & 11 mb/s on the first two write speeds, second test it scored 518 & 10 mb/s and third test finally a good result at 518 & 479. What could be the cause of such slow write speeds on two of my three tests??? it's not the C: drive where windows is installed so there shouldn't be other applications running on it, I'm using it just for storage. could something be wrong with it ??? or the slow results could be because my processor was busy with something else? after all the 12100F is not the king of multitasking.

(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.)

CrystalDiskinfo shows: Total host reads: 947GB Total host writes: 889GB Power on count: 748 count Power on hours: 50 hours I have installed only Wnidows 11, 140GB for games and some small programs. Is it normal to have so many reads/writes operations?
