I'm thinking negligible since the workload isn't going to be very IO intensive.
What kind of writes do you do, and what percentage of the time?
About a third of the files will be WORM like video content. A few websites (15). There will be 5 instances of Nextcloud for clients to test out. Unifi instance. Piwik, Mattermost, Veam B&R, Snipe-IT, Guacamole, Alfresco x 2, Fastvue, Kimai, without having actual data and only ballparking it, I'm likely 80% read. The videos are the most write intensive and even though they are large files, only get uploaded at a rate of 3 - 10 per week.

Sounds like RAID 6 wouldn't have any noticeable impact.

RAID 5 is still a solid choice. At sixtreen drives, though, I might start wanting to consider RAID 6. That's a lot of drives.
Certainly seems odd to not KNOW the answer to this question before you make a purchase.

When I hear "picked up" and "lab" I'm not thinking purchase. Or at least not an important one.

This. Maybe he just had a few older drives from another project? We are slowly walking into the area where we could see desktops and servers with SSDs getting replaced by newer machines. Just for example. Or he just bought a few of them, hell, why not? You easily get some solid SATA consumer drives with 256GB for < 70$ today -
probably good enough for a lab. -
Wow, that is a nice LAB and you will have many systems running. That’s a lot of hard drives too. What SSDs will you be using?

Not odd really. I knew I wouldn't be running RAID10 so the only remaining question was whether it would be RAID5 or RAID6. The 512GB difference in storage between the two wasn't going to change the fact that I would be setting up 16 drives out of the 24 available slots.

They're drives from a previous project I was working on. The drives are Kingston KC400s.
I'm consolidating from a few older 11th gen servers to slightly newer (without breaking the bank).

How does the server "react" to the Kingston drives since they do not have Dell's HD firmware?

I have a Dell R620 that didn't have any problems with off-the-shelf consumer Kingston drives. The indicator lights are all green even though, as expected, the SSDs appear as non-critical status because they don't have the Dell firmware (see screenshot from H710P Mini controller). The controller reads the SSD S.M.A.R.T. data and reports "failure predicted" even on those consumer drives.
These 512GB SSDs however were purchased directly from Dell so I'll know more once the server is setup. The previous project never panned out so they are still new.
-
The R720xd in its new home. The drive indicator lights are all green on the server. OMSA complains about the firmware even though these were purchased from Dell directly.
-
hardware rarely arrives up to date with firmware in my experience.
-
@dashrender Interestingly enough, this is the current firmware for this drive.

RAID 5 for SSD is a yes. Space-efficient, yet performs decently, if you need the extra redundancy and make the system future-proof just get a second server with SSD in RAID 5 and balance the storage efficiency with replicating part of the data with a VSAN type solution. StarWind can make it easier from a cost perspective due to us having a free version, but ultimately any VSAN will do the trick.

@nashbrydges Nice looking rack

@hobbit666 And that is what we call sexual harassment

old school actually with round holes. do not see that much.

@jaredbusch Rack is definitely old but as long as the rails work, it's all good

Great for the nuts and screws...

I'd gladly trade the round holes for my square hole racks with the nutcerts that have me impaling my hand with a screwdriver a few times a year.
