Experience greater reliability, durability and increased performance over traditional hard drives while enhancing and extending the life of your existing computer. With no moving parts and lower power consumption, SanDisk SSD is the smart affordable choice for your next computer upgrade.
* 1 gigabyte (GB) = 1 billion bytes. Some capacity not available for data storage.
** As compared to 7200 RPM SATA 2.5" hard drive. Based on published specifications and internal benchmarking tests.
† Based on internal testing; performance may vary depending upon host device, OS and application. 1 megabyte (MB)=1 million bytes.
Δ Based on internal testing using Telcordia stress part testing.

"...Durable Stainless-steel casing..."
-> This is wrong! The case is made of simple plastic!
"...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.

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
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.

...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?
SanDisk (R) SSD
MTBF** Telcordia, Stress Part 3.0M hours (for 128GB Drive)
MTBF: 3.000.000 h = 342 years
Warranty: 0.026.300 h = 3 years
???...so many questions...???

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

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.
