Question Insanely high amount of read and writes after just a few months. Lexar Ns 100

[Alectrona]

For whatever reason crystaldiskinfo is reporting insanely high read and writes after a few months. (48tb read) (26tb write). is it reporting incorrectly?

Probably not. Have you run Lexar's Dash tools ???

No... I have no idea how I have that much read and written

Last time I checked it was not this high... only thing ive changed between that time is installing a 500gb hdd

I can 100% confirm it is writing wrong. hard disk sentinel reports 800gb written.

@ith 26TB written (TBW) you are 10% of the warranted TBW.
Game captures is one thing that many people don't think about for writing a lot of data.

Again, what does the MANUFACTURER tool say ? That is the most valid data.

I cannot download it says its unavailable on the website

Then I guess you can pick the number you like best... 800GB sounds too low for an OS disk, IMO.

I mean do the numbers shown seem accurate to you after 3-4months of use?

200GB / day give or take. Do you do game captures? Stream movies? Run a torrent? Lots of things can generate disk writes.

No, only thing I am doing is watching youtube and light gaming (literally games like gta v).

If you google "does watching youtube generate a lot of disk I/O" you can see other people with similar situations.

maybe it is youtube but hwinfo64 is reporting differently compared to crystaldiskinfo as well

The Average erase Count is 7. The actual capacity of your SSD is 512GiB. This capacity has been rewritten 7 times, so the total data written to NAND is about 3600 GiB.

The Total Written attribute has a raw value of 0x68CB (= 26827 decimal). CrystalDiskInfo is interpreting the units to be GB, but I suspect it is more like 128MiB or 64MiB.

Here is a simple test. Record the raw value of the Total Written attribute, write a 1GB file to the drive, then examine that same attribute again. I bet it will have advanced by 8 or 16. CrystalDiskInfo will also report an additional 8 or 16GB rather than 1 GB.

HD Sentinel thinks the units are 32 MB.

26827 x 32 megabytes = 799.5 gibibytes​

​

Note that the amount of data written to NAND will be greater than the data written by the host. This is due to write amplification.

ok that makes a ton more sense one of the two are interpreting the "Total Written" attribute values differently. I ran a stress test and the values shown in hwinfo64 and Hard Disk Sentinel seem more accurate.

What does that prove? You need to write a known amount of data to the drive and then compare the before-and-after figures. You're still just shooting in the dark.

This is what i'm getting:

Power on count and hours are similar but the numbers you have are much higher.
It is a different drive, but...

Never mind ...
