    I am running an application that generates about 1TB/day of writes, the app lives on a replicated ceph cluster with size 2 and 3 hosting SSDs. Right now my 850 EVOs that it is running on are not taking it too well. Does anybody have a recommendation for a SSD which will take 675GB/day in writes (12MB/s continuously) for 3 or more years? Used from ebay is fine (provided it has a lot of life left in it), this is going in my personal lab.

    Intel S3700 and S3710 are rated for 10 drive writes per day (DWPD) for 5 years. So, those should do well in your case.
    Intel S3610 drives are rated for 3 DWPD and may also work if drive capacity is adequate; e.g., >=400GB.
    Samsung PM863 with capacities 960GB and higher should work. Samsung SM863 is an upgrade over PM863 and will also work even with lower capacities.

    What @keybored has said for SATA disks is on the money, if your willing to use SAS then a lot more options are available are good prices but still if you don’t have a sas adapter in use today then SATA makes more sense I guess.

    I have a sas backplane, I forgot to mention that the drives have to be >= 1TB.

    If SAS can be used, HGST drives hands down.

    Optane 900p

    Write endurance for Optane 900p 480GB 8.76 PB
    Write endurance for Optane 900p 280GB 5.11 PB
    Write endurance Intel S3700 200GB 10 drive writes per day for 5 years or 3.65PB for 5 years.

    And as Optane is much much faster you get better Ceph performance.

    Opinions on the HGST s840 drives? Doesn't need to be lightning fast, and appear to be rated for 10DWPD even with the 2TB drives.

    Another vote for HGST sas3 ssd's such as husmm drives. 800GB models can be had for roughly $250-300 if your patient and that falls JUST under your 1TB drive request but higher than 675GB per day and the endurance on those pups is legit. :-D

    I have a couple of stec842 ssd 800gb according to smart data they have about 40TB writes and 250TB reads and it still shows 100% life.
    I did have some weird compatibility problem when using this SSD as local storage on ESXi, but using them in a windows or linux server seems to work without issues.

    I will be using them under linux, so not overly worried about compatibility. How do they maintain speed when absorbing many writes?

    they are not the most speedy SSD to begin with, but I think they are pretty consistent speed wise. You can find review of this product online at a few places.

    As long as they don't do like the 850 EVOs and tank to ~40MB/s write after a while. I found a local seller with 2TB s840 drives for $300 each, will pick a couple up to experiment with and see if they run like I want.

    wow, 24x of those in supermicro chassis would make a killer array for reasonable price.
    I wonder what is the smart data read on those thing, @zdude can you report back when you get the drive.
