935,467.11 TB Lifetime Writes, is it a lot ?

[Fritz]

Drive in question is a SEAGATE ST3300655SS. Still tests perfect in HD Sentinel.

Power on time is 853 days.

I have another one with only 4,486 TB Lifetime Writes and almost exactly the same power on time of 852 days. I believe they were cell mates their entire lives.

When you say cell mates you mean same disk system right and maybe not the same raid group.
The high write may have been an oracle redo log drive or something like that and the other disk a raid set for the data.

 

[Fritz]

But is it a lot?

 

[Evan]

Almost 100PB is just broken in haha

 

[Fritz]

I think your math is a little off.

 

[cptbjorn]

935 PB is not even close to possible with 6Gb SAS in 853 days...

 

[Evan]

Over 1PB per day... Your right, can't be done

 

[Fritz]

Really?

 

[Fritz]

HD Sentinel or the HD must be lying.

 

[cptbjorn]

Yeah that would be ~12 gigabytes per second. It would actually take a couple hundred years to write that much to a 15k 300GB SAS disk.

Edit: 4486 TB is possible but you'd almost have to be trying. That's 60 MB/s.

 

[Fritz]

Are lifetime writes stored in S.M.A.R.T. ? I'd like to know if it's the drive or HD Sentinel.

 

[Fritz]

Sorry, that's the other drive. Stand by.

 

[cptbjorn]

I'm not sure where it's pulling that from but it can't be right. I've seen drives that showed total LBAs written and lots of SSDs show some kind of write counter but not all SAS/SATA drives expose lifetime writes in the SMART data.

 

[Fritz]

smart data in HD S shows the same value. I need to find another program that shows smart data. I have a feeling that HD S is full of bullocks. It shows decreased health for SSD's when no other program does. I posted about that some time ago.
