Hello Samuel. Thanks for the answer. Yes the Intel S4510 series is a good choice but it's expensive. I have 21 server and data distribution is quite well. At power loss I don't think I'll lose data. All the VM's using same image and the rest is cookie. In this case I'm not sure I should spend extra money on PLP. Actually I like Samsung 870 EVO. It's cheap and I think 300TBW will be enough for 5-10years. Do you know any better ssd with the same price range as 870 EVO? Samsung 870 evo (500GB) = 5 Years or 300 TBW - $64.99 Samsung 860 pro (512GB) = 5 Years or 600 TBW - $99 > > I would recommend Intel S4510 series, which has power loss protection (PLP). > > If you do not care about PLP, lower-cost Samsung 870EVO and Crucial MX500 should also be OK (with separate DB/WAL on enterprise SSD with PLP) > > Samuel > > ________________________________ > huxiaoyu@xxxxxxxxxxxx > > > From: by morphin > Date: 2021-05-30 02:48 > To: Anthony D'Atri > CC: Ceph Users > Subject: Re: SSD recommendations for RBD and VM's > Hello Anthony. > > I use Qemu and I don't need size. > I've 1000 vm and usually they're clones from the same rbd image.
