Need advice on building a rig with HDD's



  • Hi there,

    Slowly I am thinking to build my own mining rig. Goal to reach as for now 80GB and later twice that size.

    Ok so I crossed to couple of nice HDD based devices, one of them is the WD My book 8 TB and Drobo 5C.

    By buying 2 Drobo's and 10 HDD 8TB standalone from wd red, 5 HDD in each bay would be operated by only 1 usb 3.0 hub. I suspect that this setup will not be right for mining as I read somewhere that it is better to buy instead an HDD device that could be operate by 1 hub, because it would be better if 1 HDD is being read by 1 usb hub instead of 5 in the same time.

    The WD my book on the other hand does not have a HDD wd red label inside, the guy in this video below opened up one and the drive inside was labeled as white, as my knowledge about wd labeling I only know that red means it's power friendly, I don't have any clue about this white HDD drive inside WD my book (here I am asking someone to advice me)

    Or go hardcore and just buy 10 wd red label and connect them all to the MOBO. (it will be painful that's why I was thinking about buying HDD's that will be operated in usb hubs).

    So there is the dilema and I couldn't decide yet, for now I am sure that buying 10 separated HDD with their own respective usb connection would be better instead of buying 5 HDD with a drobo that operates only 1 usb hub for all the storages.

    What do u guys think and maybe u can throw some advice, I would be happy to read them.

    Cheers o/



  • @pr0cesor some like Seagate external drivers d3 station

    I forgot about the Seagate, thx. I found in my country, its in the same price as the WD my book for 8TB



  • But.... there is a big BUT... I just found out that the Seagate Backup Plus for example need classical socket to power it up which really sux. I was expecting to power them with my PC. In this case the WD my book has a big plus in term of powering the drives.



  • @pr0cesor
    On the cheaper end of SATA III controllers, one of the 8 or 16 ports ones lists in the link below.

    0_1487874741395_syba_8_and_16_port_controllers.png Another consideration is power usage, USB hubs, and USB 3.0 external drives also use power adapters. Whereas connecting the drives drives directly would use less. Also the less complex a system the less that can go wrong.

    Sorry for the noobish question but for what those SATA3 controllers would be? The WD red label drives? Or the drives with usb 3.0?

    And previously I was talking about this Seagate drive

    alt text

    It has 2 usb ports, 1 for usb3.0 and the second for power (That's what I read from the website)

    ---EDIT

    Ok I understand now about the SATA3 controllers, those are for the WD red label drives and I just have to power the 16 drives to a PSU for example. And SATA controllers are better than USB hubs right? in term of speed reading and data transfering. The WD red label drive would be then less consuming power if the would be powered directly by the PSU instead of the USB hubs, make sens. Am I right? :D (sorry I was thinking loud xD)



  • @pr0cesor Any SATA III drive, or a SATA drive that can do 6Gb/s(They are one and the same). Inside all of external USB3.0 drives is a SATA III drive that can be extracted and connected via a SATA cable directly to a SATA controller. The drives would be powered by the PC power supply via a molex cable.

  • @iKnow0 The before setup...

  • Cool thank u. I will take this in consideration, I have a gaming PC, I have already a gtx970, asrock z77 extrem 4 mobo, 16gb ram, i7-3770k OC to 4.4 ghz gonna just have to look on the drive bay again to see how many drives will fit inside. ^^

    Edit---

    I can fit 8 - 3.5" HDD trays - all compatible with SSDs, 2 - 2.5" extra SSD positions in my case (from producer website)



  • @pr0cesor good luck with your build...

    How my build sounds? :D will it work?



  • @pr0cesor my advice, start small then add to it. Issue will arise and there is a learning curve.



  • if you have the room for lots of hook ups lowest price i found is on new egg 2tb 47$ all the reviews say they loud as crap but work good https://www.newegg.com/Product/Product.aspx?Item=9SIA5AD3KE4333



  • they have cheeper if you dont mind refurbished but i dont use refurbished HDD's
