Hello.
I know that each HDD has a standard life and after it HDD maybe burn or fail, But how can I understand How much of the remainder of its life? Any program? Can "HDDlife Pro" help me?


Thank you.

Agree with you here, But WILL NEVER tell you when it`s gonna die/stop working.
like the Dr. Opinion will tell you how good/bad is ur health based on some tests, but never tells how much time you have left.

just backup your files and ur good :wink: my opinion

There are certain SMART attributes which estimate the remaining life based on the actual number of PE cycles as a percentage of the rated PE cycles.

I guess S.M.A.R.T is a option that I need. Can you show me a good tool for estimate it?

Smartctl is probably one of the better tools for SSDs.

If you think that watching SMART will give you any real indication of when a HDD or SSD is going to fail you are sadly mistaken. There are really only certain types of issues which cause failures which SMART can even detect in advance. The sad reality is that most HDDs and nearly all SSDs fail suddenly and with absolutely no warning.

Need to have a backup, you can't just rely on the health of a device.

"Lifetime" and "health" are two different things. An SSD's life is limited by its P/E cycle rating. That said, one would need to really thrash an SSD to rack up 3000 P/E cycles. It just wouldn't happen in normal use.

Quote:
ID # 177 Wear Leveling Count

This attribute represents the number of media program and erase operations (the number of times a block has been erased). This value is directly related to the lifetime of the SSD. The raw value of this attribute shows the total count of P/E Cycles.

I know HDD have a useful time and after it they can't working properly but why HDD manufacturers doesn't provide any useful information about their life in hours? For example, Write on HDD a text like "This HDD can working properly for 1 million hours".

Manufacturers provide an MTBF spec. It is intended to estimate the failure rate of drives in a large population, but is essentially useless for estimating the life of a single unit.
