ssd usage and expected life span

Baldrick1001 · 18 Feb 2010 at 22:31

I bought an Intel 80gig Gen 2 SSD a couple of weeks ago. The SSD has been installed for 11 days and I am suitably impressed with how snappy the system now feels. My only concern is how long will the disk last. I have installed around 38 gig of op system and programs but when i view crystaldiskinfo it tells me that I have written nearly 200 gig of host writes - i take it that this is virtual memory, swap file etc - 200 g does seem high for 11 days though - is this normal and, based on this type of useage - how long will my HDD last (projected)??

Cheers

Quoted from some other site.

"Intel claims the ability to write 100GB a day, every day, for 5 years"

how did they know that? not like they have test it for 5 years before sell them

It's pretty easy for them to calculate with SSDs, as the NAND has a set amount writes before it starts to die, you just have to do the math.

They must know it can write at least 182,600 GB of data [100 x 5 x 365 + 1] based off their knowledge of the number of writes the NAND can do.

182K GB is not a very useful number in regards to its lifespan. Saying 100GB a day for 5 years immediately tells you it has a pretty long life!

EDIT: Even if it was half that [only 2.5 years] odds are you will be onto your next SSD by then anyway!
