Re: SanDisk® SSD

No. 1:

"...Durable Stainless-steel casing..."

-> This is wrong! The case is made of simple plastic!

No. 2:

"...MTBF Telcordia Stress Part..."

-> Please explain in an easy-to-understand-way what exactly this means for the enduser. Do we need to think about data loss as many people in the www talk about a lasting time of SSDs of about 3 years only.

Re: SanDisk® SSD

Simply put MTBF (Mean time between failure) is the number of hours the product is rated for before you could expect a hardware failure. See link below for a more detailed definition of MTBF

 

http://en.wikipedia.org/wiki/Mean_time_between_failures 

 

That said SSD life is highly dependent on how heavy of a write load you have in your environment. A typical consumer usage probably would not come close to what these drives can handle within the warranty period. Best thing to do is keep a check on your SMART attributes. If you see one of the attributes trip to fail it is time to replace the drive.

Re: SanDisk® SSD

...still so many questions...

 

"...A typical consumer usage probably would not come close to what these drives can handle within the warranty period..."

Thank you for your info but what exactly does this mean? Do I have to expect a failure after 3 years only? In case the drive will hopefully last for only 3 years how can I rely on this kind of storage system?

 

About MTBF

SanDisk (R) SSD

...

MTBF**   Telcordia, Stress Part   3.0M hours (for 128GB Drive)

_____________________________

 

Calculation:

MTBF:             3.000.000 h = 342 years

Warranty:       0.026.300 h = 3 years

 

???...so many questions...???

Re: SanDisk® SSD

...more unclear points...

 

"...Best thing to do is keep a check on your SMART attributes..."

 

 

Current Value, Threshold, Raw Value - a lot of numbers, but without the knowledge of the basis/perfect value I am not able to interprete these values.

 

One example from the picture above:

 

current value=200

theshold=51

 

nice to know but again what does this mean???

Re: SanDisk® SSD

You can read up on SMART here http://en.wikipedia.org/wiki/S.M.A.R.T.

 

Basically current value is where the SMART attribute starts. It will count up in the RAW value and down in the current. Once the current value reaches the threshold the attribute will trip to fail.
