Samsung 860/870 EVO 4TB, terible performance after a year (or two) of use

[OwenBurnett]

Hello,

I have 5 860 EVO 4TB and 3 870 EVO 4TB,

I used them for 1-2 years

the 1 year old 870's have about 20 TB written

and the 2 year old 860's have about 40 TB written,

Since a couple of months i have noticed a terrible performance degradation

 

 

 

Samsung magician claims the drives are fine,

but look at that write rate this is not fine,

I have tried the on board sata ports as well as a Adaptec controller card, same low result.

 

Is this a known issue with these SSD models?

Is there a solution?

I tried creating new volumes and deleting them to force trim on the entire ssd, but that did not help.

Would a complete erase from a boot stick as samsung magician offers help?

 

Cheers

Owen

Ever used TRIM?  Optimize in Windows.

as I said: "I tried creating new volumes and deleting them to force trim on the entire ssd, but that did not help." so yes the drives are trimmed and when I look with winhex the drives are now all almost exclusively filled with 0, as the ssd should report back for a trimmed sector.

Just secure erase em in bios then.

 

It's weird there is such a dip maybe a wipe helps but that doesn't figure out what caused it

I use old server hardware there are no functions in the bios to erase a drive.

Can you recommend any bootable tool that woudl do it right and not just write a lot of junk to the driver?

I wasn't aware that actually did that. In any case, my method is to run this in powershell as admin:

 

Optimize-Volume -DriveLetter C -ReTrim -Verbose

Changing the C to the drive letter.

 

Worth a try.

trim does not help what's next?

[OwenBurnett]

do you think i could warranty them with samsung?
