    Specs ok for a sata drive but price is a bit steep, you can get enterprise drives for 2/3rd the price (sata) and even if warranty is a bit not confirmed you can just buy more.

    For me I wound want the it to be $100/TB

    You can buy Samsung 860 evo for $100/TB new... and used (lightly) other drives like micron or sandisk for less.

    I've had quite a few issues with non enterprise drives when used in various configurations. I don't know anything about the WD RED SSDs but unless they can handle steady state writes without falling flat after a short period of time they will have limited usefulness. Of course their red line has always been made for multi drive arrays so hopefully they will act more like enterprise drives than consumer drives. Also Evan is spot on, used or old new stock enterprise drives are cheaper :).

    I agree with @Jeff Robertson but if this is for work just buy new ones with a proper warranty. If it is for personal use consider buying from a white box vendor who will at least give you some kind of warranty.

    Anyone know if the WD Red SSD supports DRAT (deterministic read after trim) and RZAT (read zeros after trim)?

    Just got a reply back from Western Digital and they said the SA500 supports DRAT and RZAT.

    Good luck with that.

    Almost $600 for a consumer 4TB :eek:

    Your right but some people feel warm and fuzzy with that 5yr warranty rather than spares of better drives on the shelf or money saved.

    Can you get academic pricing on the drives?

    Mini article here here: Western Digital Launches WD Red SA500 Caching SSDs for NAS

    Highlights: Very much intended as cache drive is prosumer/SOHO NAS devices/systems; Write and mixed workload optimized; TLC NAND.

    Too bad they don't come in NVMe (the M.2 are SATA only it looks like)

    On a related note, has anyone looked into modified firmware to operate an SSD in full SLC mode? Just curious with a modern controller how good you could get "worst case" IO.

    # zpool trim wdssd_tank
    # zpool status -v wdssd_tank
    pool: wdssd_tank
