SSD recommendations for RBD and VM's
Hello. I have virtualization env and I'm looking new SSD for HDD replacement. What are the best Performance / Price SSDs in the market right now? I'm looking 1TB, 512GB, 480GB, 256GB, 240GB. Is there a SSD recommendation list for ceph?
The choice depends on scale, your choice of chassis / form factor, budget, workload and needs. The sizes you list seem awfully small. Tell us more about your use-case. OpenStack? Proxmox? QEMU? VMware? Converged? Dedicated ? —aad

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. The image is 30GB. Right now I've 7TB Stored data. rep x3 = 20TB data. It's mostly read intensive. Usage is stable and does not grow. So I need I/O more than capacity. That's why I'm looking for 256-512GB SSD's. I think right now 480-512GB is sweet spot for $ / GB. So 60PCS 512GB will be enough. Actually 120PCS 256GB will be better but the price goes up. I have Dell R720-740 and I use SATA Intel DCS3700 for journal. I've 40PCS 100GB. I'm gonna make them OSD as well. 7 years and DC S3700 still rocks. Not even one of them is dead. The SSD must be Low price & High TBW life span. Rest is not important.

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@horebdata.cn From: by morphin Date: 2021-05-30 02:48 To: Anthony D'Atri CC: Ceph Users Subject: [ceph-users] Re: SSD recommendations for RBD and VM's Hello Anthony.
