Kingston a400 120gb ssd lifespan

assassin5675 · Mar 24, 2018

Hi, I was wondering how long the Kingston 120gb A400 would last. It has a 40 TBW. I read it depends on how much data is written per day but I don't know much data I use per day, I mostly use it for YouTube and a little bit of gaming as well as work. Could someone estimate what 30gb of data a day written looks like?

How long have you had it?
What is on it currently?
What is telling you "40TBW"? Because that's actually a lot.

My main system has 5 SSD's, the eldest almost 6 years old. And totaling ALL of them is only 40TBW currently.

"40TBW" basically equals 30GB per day, every single day, for 3 years.
4 full length movies, maybe. Every day.

Use Kingston SSD manager. It will show you info about your Kingston SSD.

i want to know if youtube writes on my ssd and how mich 10gb writing looks like practically. Its brand new

If browser cache folder is located on ssd (you haven't relocated it to somewhere else), then yes - all youtube videos you have ever watched would get downloaded to temp folder on your SSD.

So then that would take up like more than 30gb per day (of writing onto ssd) because YouTube is used for 6 hours a day by a few people in the house

Possibly.
Only real way to know is to monitor it on a regular schedule.
Once a week for a couple months.
See how and if it increases.

The 40TBW number comes from Kingston's own spec, at this page on their website: https://www.kingston.com/EN/ssd/consumer/sa400s37

The number, as you'd expect, is proportional to the drive capacity for this range. 40TBW to 120GB, 80TBW to a 240GB drive, and so on. I gather there are other factors in this, these drives are dropping in price, and not so different from a USB stick of similar capacity from the same supplier. I doubt any USB stick comes close to this life.

A lot depends on your use, but I doubt I can reach the 30GB/day.

Right.
I had thought the OP was referring to an actual reading that told him it had already consumed 40TBW.
Not the warranty lifespan published by Kingston.
