    With QLC I guess we coming closer to line where it could cheaper for datacenters to have SSD instead of HDD. HDD could still be used for backups, not active machines that work 24/7.

    HDDs does fail more frequently (in my experience), have movement parts, consumes more energy, requires more cooling and takes more space. I am not mentioning the performance here.

    So once we weight all risks and additional costs HDD will bring, it actually might not be a bad idea to have SSD instead. The only moving parts left in servers are cooling.

    33% more density, at the cost of 3x of the cycles. No thanks.

    If cheap enough QLC drives should make a good secondary storage drive like for media or backups.

    How about long term reliability if powered down? I think you can lose your data if you don't power it up from time to time. But I'm not sure about that.
    PS: The price will probably not go down as we might hope. It will probably stay the same as TLC and go down slowly with time.

    Prices are going down on daily basis...
    New ADATA XPG GAMMIX S11 SSD 480GB is pretty fast and undercuts competition. I sense Disturbance In The Force.

    Well until I can get a 2+ tb ssd for under $100, I wont be switching to ssd's for storage any time soon. It will happen eventually though, cant argue with that!

    i wonder are there any data-center start moving out from HDD and start deploying/replacing to full SSD yet ?

    the limited write-cycle seems one of the concern for data-center, which why SSD designed for data-center still expensive

    i read somewhere that google using DRAM+HDD, so SSD unnecessary

    I think most HDD would fail before SDD reaching its write cycle limit.

    I think the appeal for an SSD is not storage at all. The access times and R/W speed as always been the number 1 factors for me.
    My best friend was not convinced by 256Gb drives but I bought one as a boot drive: best purchase I've made since my 2500k. In the future I'll probably buy a 512Gb SSD and move this one to my mothers computer as a boot drive.
    Large capacity is only worth it for work on workstations, if you do allot of video editing with 4k content, etc.
