    When it's written as 131GB writes/day for 3 years it seems like more than enough.
    But cell endurance of 144 writes seems really, really low.

    It doesnt work like that. 144TB for 1TB doesn't translate to 144 p/e flash. You have to factor in write amplification, which can be more than 1 on controller like this.
    Also conservative rating is nothing new with budget driver.

    Stupid question: has anyone any experience with SSD reliability over time. I.e. is it reliable to store static data 3-5y+? Or does the 3y (or 5y) guarantee also means the data should be migrated out after that period even if the number of writes has been low?
  • hojnikb - Monday, February 9, 2015 - link

    Its just a conservative rating for warranty purposes. Besides, other value drives are no better at this (evo is only "good" for 150TB).

    In reality, drives typically last many times the rated endurance.

    More importantly, it's set low to scare off enterprise customers who'd subject the drive to an order of magnitude more IO.

    So if the endurance is 144TB on a 1TB drive, they are predicting the nand can only take 144 writes?

    That is a bit scary for even home use. I wouldn't trust my data to that.

    There is not a single medium or drive out there that you should trust your data on. Only thing you can trust is redundancy.

    No. Read my post above ^^

    the 512GB crusial mx 100 endurance is only 72TB, yet people dont seem to be complaining. besides, as typical day to day use only accounts for maybe ~10GB or writes(3.65TB a year), the 144TB endurance will last far longer than the machine it is put in.

    yeah problem is that until it's broken, I'll keep moving it on to the next machine.
    But I write about 1 GB/week to the SSD so I should be safe, unless windows does a lot of that in the background, I don't know, I just deactivated all the bad stuff I read about.
