New to mining: Seagate 8TB archive HDD and plot optimization question

@kaydencc said in New to mining: Seagate 8TB archive HDD and plot optimization question:
@luxe About ram, my system has 16gb of ram with i7 6800k. Is there a certain ram requirement for mining with 70 - 80TB? I saw your screenshot in "Post your mining rigs" thread and you had 19gb of ram used.
I also don't know if there will be a bandwidth bottleneck with 10 drives on 10 sata connections because my 28 pcie slots are maxed with 4x Rx 480 for zcash mining.
@kaydencc no that ram is not used for mining, i just had a vm running or something, 16GB is more than enough.
I do not think you will have a pcie bottleneck, 28 lanes/pcie3 -> ~28GB/s for a round of burst mining @100TB you will only need ~25GB ... (~100000GB/4096) so you pcie will only be used 1s per 4min :-)

@kaydencc I've just stumbled on your topic. I've ordered 500TB of those drive to start Burst mining operation. Could I message you in private for details on your rig and basic questions?

@Burstde since last post Seagates have been good up to 6 drives now

Those Archive drives have a lower RPM & smaller Cache than other versions. Does that make much difference to the Plot read-speed when ฿urst-Mining?

@BeholdMiNuggets Heya, I have 6 of these 8TB archive drives. Once plotting is done, their reading speed is just fine, no problems with them - so far.

Thanks ~ which Burst-Miner do you use and how long does it take to Read each 8Tb drive, and in total for all Six?
-
@BeholdMiNuggets I use the new Blago miner with AVX2 and it takes about 30-35 seconds to read 76 TB in total

Ok, cool. I guess it depends on the system resources. What Cpu, Ram & Allocated Treads are you using for your Burst-mining (via the Blago code)? Also, it looks like you have a bunch of other Capacity, in addition to the (6x) Archive/8Tb HDD.

@BeholdMiNuggets I just left it on default...I didn't change any settings other than pool and such. The rest of my HDDs are WDs ; I usually buy externals and pull the drive out and use them internally.

Yeah, the pricing for the external drives is odd. I'll have to look up how much faster SATA is than USB-3 (& mining /scanning times). Thou have run out of internal ports, so will need a PCIe adaptor card if staying internal. Plus, I guess you don't care about the external-drive Warrantee!
-
@BeholdMiNuggets imho, most externals fail because of heat (could be dead wrong, but that is how I feel) , so when I put them in the case they are well ventilated . External's price is a lot less then internals , so yeah...I just use them and if they break, I'll change them, so far no problems ;-)
