If you go with SSD's you'd use OBR5.
If you went with 15K drives you'd use OBR6.
Why?
OBR5 is safe (enough) because URE's don't happen with SSD's. SSD's just die. So you'd replace it as soon as it died. They also rebuild way faster.
OBR6 with 15K drives because you have a lot of them, but they are smaller capacity (300GB). So you'd get enough performance and the most usable space from the array.
oooh. I didn't know that about URE's and SSD's

4x 6TB drives
That's 12TB usable in RAID 10. Not sure why that wouldn't be a good option.

Because I was planning to not use them for this.. but now I'm considering changing my mind.

Oh I see. What were you planning on using them for? Could you roll that into this via a VM and application?

They are in a different server now, holding some files.

Spend the $15 to get a USB drive to be the install target for Hyper-V, and then boot the server from that USB drive each time. Like others have said, keep the SSD to give yourself some fast storage to play with and not to run a hypervisor.
If you're only playing with a single SSD you could even leverage it and use the free version of Starwind to accelerate the VMs running on the spinning disk datastore (I think). Someone else may want to verify this specific point.

I do have plenty of extra USB drives. I was considering that also but I don't know if I want a USB drive sticking out of the back of my server.

Did you say what size the SAS drives are (2.5" or 3.5")? I missed it if so. I'm curious if the SSDs will fit in the Dell drive cage chassis properly if they are 2.5" and the SAS disks you have are 3.5".

You can get a really slim USB stick online for cheap.

SAS drives are 2.5" and I have some caddie spacers that let me use 2.5 in 3.5 caddie. I do already have one 2.5" consumer SSD running in this server, waiting for me to finish installing Hyper-V as we speak.

Maybe I will just install Hyper-v on my current USB just for S&G. I've never installed Hyper-v before so I don't mind having to do it again on a different, smaller USB later..

It never hurts to practice so you have the install down cold.
That way if this is used in production at some point (I mean Hyper-V and not your lab gear), you will be ready for a complete re-install if absolutely needed in a DR scenario. -

I assume both will work fine but I've never really used consumer SSD's on a Dell server before.. input?
Don't do it. It's going to suck, if it even works.

It is extremely ill advised to run Hyper-V from a USB or SD-Card.
It's not officially supported and prone to failure.

@dave247 said in Enterprise 15K SAS drives vs consumer grade SSD in a Dell server?:
my plan is to use slot 0 and 1 for two drives in RAID1 for the OS, then use the rest for a RAID10 array for storage (at a later time).
Don't do that either. Do the OBR10, and just use a small partition for the OS, and the rest of the space as REFS for Hyper-V storage.

Oh really? Oops. Ignore that then. Too much time running VMware I guess....

Yeah, VMware is the only hypervisor today that fully supports and automates that approach.

It would be like cooking a hot dog by standing behind a fighter jet as it preps to take off.
Love that analogy

I'm putting Hyper-V on a decommissioned Dell R510 for a general LAB environment and testing, etc. I'm trying to scrounge up some spare drives (I have a lot) for a stable/reliable config. I have 8x 3.5" drive bays on this thing and my plan is to use slot 0 and 1 for two drives in RAID1 for the OS, then use the rest for a RAID10 array for storage (at a later time). Yes, I know usually you'd just do OBR10 but I'm not doing it that way.
Right now, I'm trying to decide which would be better: a set of 300GB 15K SAS Dell Enterprise drives or a set of consumer-grade 128GB Samsung 840 Pro SSD drives.
I assume both will work fine but I've never really used consumer SSD's on a Dell server before.. input?
I own 2 R510's with 12 bays and the H700 card. I know from experience that while the newer generation servers (X20 and X30 generation) often reject drives, this server and card combo, as long as you've updated your firmware and drivers, will accept pretty much any SSD drives. I have a R620 that failed to power up with more than 3 of a specific SSD but 12 of those same drives in the R510 worked beautifully.
Edit: for spelling.

@dustinb3403 I'll take a bag please, I'm going to the gym tonight so will probably be low when I'm done!
