What is the life expectancy of the MBP's PCIeSSD

How long is the PCIe SSD expected to last in a MBP ?

How many TB writes?

Does OS-X monitor the TB writes to the SSD on a MBP ?

What is the warranty on the PCIe SSD ?

Hi,

There is no life expectancy listed anywhere for the SSD. But for a comparison, Samsung offers a five year warranty on its higher end models. Most products last well beyond their warranty period, so I think it's safe to say the SSD will last about as long as the MBP does. Note that it also has TRIM support, so that helps.

The warranty period is the same as the MBP's hardware, one year, unless the AppleCare Protection Plan is purchased within the first year, then it will extend the warranty by two years, for a total of three years warranty.

To my knowledge, OS X does not monitor TBs written to the SSD. I wonder if there is a third party app written for that.

A lot depends on your usage. Generally, with normal use, barring any

other electrical failure, you MacBook Pro will likely be obsolete before

the SSD "wears out".

I found this article on the internet that tells you how to check to see how many TB's have been written to your SSD.

Good find Alex! I remember reading that article now and not worrying about it after I read: "If you wrote 100GB of data a day, which I doubt you do, it would take you 10,000 days or 27.4 years to write 1PB of data to your SSD."

Yes, I found this Samsung 950 SSD Chart for comparison.

It appears that the some older budget 3.5" SSD are not very good some failing at 100tb.

So I guess you get what you pay for in most cases.

Most users will only write about 5gb. per day.

Samsung offers a 5 year warranty or 200tb on the 950-series.

At 200tb divided by 5gb per day = 40000 divided by 365 days = 109 years

Most SSD's even the New Budget 3.5 6gb. SSD can achieve and surpass 200tb.

So I would assume it is safe to say that not to worry about the PCIe SSD going bad

in the Mac as it will most likely surpass the life of the computer in most cases for the average user.

TB writes appears to double with larger capacity SSD's.

So an SSD with 500gb. should last twice as long as an SSD with 256gb.

It is safe to say that purchasing a MB with a 500gb SSD is your best value purchase.

Where this 500gb. SSD should last twice as long as an SSD with 250gb.

At least 400tb writes. At 5gb. per daily usage this SSD should last up to 219 years.
