Micron 5100 Pro SSDs in RAID 1 or a single Intel PCIe DC P3700 drive???

[rsumperl]

Hello everyone, I'd like to get some opinions on "C" drive hardware for a new Exchange 2019 server. I'm looking at two Micron 5100 Pro SSDs in RAID 1 or a single Intel PCIe DC P3700 drive. Any thoughts? Obviously, the RAID 1 configuration offers some "safety".
The motherboard is an Intel S2600STBR, 384GB of RAM, and dual Intel Xeon Gold 6248 Processors. The Exchange databases will be on 15K drives in RAID 10 and the logfiles will reside on 15K drives in RAID 10. The RAID controller is an LSI 9460-16i.


Thanks everyone!
Ray

You're really using hard drives like that in 2023? I would have taken the $5k in CPUs and spent that on SSDs for the data...

A NVMe boot drive won't do anything for you when you're going to be bottlenecked by having a bunch of hard drives. RAID1 is a better option for uptime.

I would recommend swapping all disks to be sas ssd's instead. I would check if your box supports U.2 disks, if they do - just get u.2's instead of nvme's.

800G sas ssd are much faster than 15k sas hdd's, and price wise only a bit more expensive. The 800G SAS3 SSD *12Gbps, have typical endurance of 36PBW. New ones can be expensive (especially if branded by dell etc), but lightly used ones frome bay or some server hardware reseller can be within 100-300 USD.

I myself bought few HGST HUSMM1616ASS204 (reformatted to 4kn) (HGST/WD Ultrastar SSD800MM 800GB SAS 12Gb/s 2.5" Enterprise SSD HUSMM8080ASS200 | eBay) and had avg of 780MB/s write, and 1148MB/s read from a single disk. With only 12TBW written on them before (almost nothing). I think the spinning rust days are over, now that you can aquire sas ssd's for cheaps.

as others say, you have way to much cpu/ram, vs drive here and iops.

how many TB of storage? and aprox clients
