I'm bad at SSDs specs trying to decide between Intel 1.92TB S4500 and D3-S4510

So I need a bunch of SSDs to build out a new server. It will basically be an overpowered NAS that I may occasionally use for server stuff too. I will be running a R730xd with the H730 and either RAID 6 or RAID 50 with the drives in groups of 8. I'd say on average I do 50GB of writes a day. Not so much on the read side of things. I like the Intel 1.92TB S4500 I am running, but people are too proud of them right now. I am eyeballing the D3-S4510 models instead.

I don't particularly understand how to tell if a drive is read/write intensive or if that even matters for my piddly amount of use. I basically just pick a brand I like that has a good endurance and standard speeds. Looking for advice if the D3-S4510 would be fine. Also suggestions on the RAID option although other people seem to lean towards RAID 6.

With 50GB a day, endurance is really irrelevant for your usage (even consumer ones have no trouble with that). Any SSD from a reputable brand should do.

Well, the old Intel S3500 1.6TB sata drives will do 8PBW... All of those older MLC 1.6TB Intels will do that. I think the 1.92s are on the newer 3D NAND and are TLC... they should probably do about the same.

Yeah I believe the S4500 can do around 3PB writes and the D3-S4510 6PB writes. Although I think I read somewhere the endurance depended on the type of writes being done. Over my paygrade though.

SSD's has a lot less errors than spinning drives and also as SSD's are smaller, rebuild time is quite fast. Going for Raid5 is fine as long you have a good backup strategy. But when you have a large group of 8 I think raid6 is better. I think raid5 is fine for a group of max 5 drives

Write amplication depending on workload is definitely a factor. Some workloads are such that writes can result in 4x the actual committed blocks on the underlying storage, so you'd go through that wear life 4x faster than expected
