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.

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

Forget about 15K spinners. For consumer-grade SSDs make sure your SDS of choice is OK with them (StarWind is OK, VMware vSAN / S2D are NOT OK f.e.)

I would also recommend you not to waste two drive slots for RAID1 OS partition especially if it's a hypervisor host. USB Flash/SD Card/SATADOM/whatever will do the job leaving you with 8 free bays for OBR10 or OBR5/6. Speed all the things up with StarWind (as mentioned above) and you are good to go.

I was told that USB Flash and SD were no longer supported by MS and not to do it that way.
Anyway, I ended up just using 4x 1TB drives in RAID10 but I can't even install Hyper-V 2016 because that OS does not support the Perc S300 RAID card I have in m R510. Looks like I have to use 2012 R2 instead.

Perc S300
Looks like someone found a work around for that controller - but then others really recommend replacing it.

You can probably get an older RAID card on ebay pretty cheap.

lmao, I figured as much. I do think I'm just going to replace the card as it is a hunk of crap.

Remember to get a lot of cache and battery backup.

It was never supported outside of some OEM use case that I have never spotted in the wild. Yes it can be made to work, but it is not supported.

I thought the S300 was fake raid? I never buy anything but the H700.

If I recall it is software RAID, but not exactly fake because they never claim that it is hardware. Openly software RAID, I believe.

Thanks for the clarification.

I replaced the S300 with the H700 (with battery) but I'm pretty sure I broke the hard drive backplane because the fricking B SAS cable was stuck in there so hard it took me forever to pull it out. H700 let me put all 8 drives in RAID10 and install Hyper-V.. but then in the middle of it started yelling about the bad SAS cable.. I'm getting a lot of hardware experience though
