New to mining: Seagate 8TB archive HDD and plot optimization question
-
Thanks for the advise guys. I'll try to find 8 to 10tb drives with 3-5 year warranty for below $35/tb during deals. There's actually a used 10tb seagate hdd on amazon for $350 now, but it doesn't ship internationally. Linked here if you guys want it (only 1 left).
If there aren't alternatives, the archive drive shall do. Flexibility is worth a little extra as I may use them for storj.io or sia in the future.
@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.

Here is a better picture of the two drives I have that were both once new and now all 4 replacements of each were re-certified. I will say this is they do honor their warranty if each one was replaced. They better still honor them cause I just noticed they gave me one made form last year

No, you can not mine directly to a polo account, cause you do not know the passphrase for that account and you will need it to switch pools or even solo mine.The 8TB Archive drive of Seagate is due it's specification like made for burst mining.
But you will have speed issues if you plan to optimize plotfiles on same drive, so best would be to plot to another drive, maybe in 500GB steps ... and than optimize to your archive drive. I have 4 of this drives running and no issues so far ... running for one year.Btw. it's not just the archive drives but also some desktop drives, that use SMR, learn what SMR means and decide if you really want such a drive or if you want to invest a little more to get a more flexible drive.

I do not know if the drives have a high risk of getting corrupted or something, i'm just saying (and i repeated it here) that their specification fit nearly perfect with the needs of burst mining.- Their annual Workload Rate Limit 180TB is nearly like the needed 250TB for burst mining ...
(8TB / 4096 scoops ) * 356 days * 360 blocks per day = 250TB - They are made for running 24/7
- They are meant to be written once and than only read with up to 180MB/s
- They are cheap capacity compared to other drives (no that cheap anymore, would not pay more than ~210€)
Thank you luxe, I always learn something new from your posts

@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 ;-)
