RN102 - Disk Upgrade
Hi all, I need to upgrade my NAS changing the actually 2x4Tb disks with 2x6Tb or more. For changing disk can I change one drive at a time and wait for the realignment/rebuild of system? Than...
Of corse. The fan has become noisy as a result of the numerous times that I have cleaned it from dust.
I will look for a fan with equal revolutions and, if possible, greater CFM
Thanks
My appologies. I guess I read that as 4 x 2TB, not 2 x 4TB and answered accordingly without ever noting my error. Should have been obvious with a 2-bay NAS.
No problem.
I take this opportunity to ask for advice on the disc (obviously a couple) to buy: Western Digital WD101EFAX or Seagate ST10000VN0008? I didn't found a site that compares them. Looking at the datasheets they look the same, apart from the rotation speed: the WD is a 5400 RPM, the other is 7200. Which do you recommend?
thanks

I have seen nothing reporting that the 10TB WD Reds are SMR, though smaller ones are (without WD disclosing that until pressured to do so by unrefutable evidence they are). But, they changed the part number, so who knows.
AFAIK, the Seagate is not SMR.
While WD claims the SMR reds are fine for NAS use and I know of nobdy who has issues with them on a ReadyNAS (including myself -- I replaced one red and got one of these before it was known they were SMR), but users of some other NAS (notably UnRAID) have had issues.
I'd go the the Seagate or move up to the red pro.

Both are good choices. Generally speaking the WD Reds use less power and run cooler than the corresponding IronWolf drives. So I'd personally pick the Red drive.
Hi,
I have succesfully changed my NAS disks with 2 new WD101EFAX discs.
I noticed a considerable increase in the temperature of the disks and the CPU. I have changed the fan setting to increase the air flow, but it has become very noisy (I will also have to change the fan).
On this I have two things to ask you: what is the maximum acceptable temperature for the disks and the CPU?
Does anyone have the characteristics of the fan mounted as standard? I'd like to look for an equivalent.
ThanksSemola

WD specs the operating range of the WD101EFAX as 0-65C here: https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/product/internal-drives/wd-red-hdd/data-sheet-western-digital-wd-red-hdd-2879-800002.pdf
The datasheet of the Armada 370 CPU is surprisingly hard to find, but there is a copy here: http://dtsheet.com/doc/1285717/armada-370-hardware-specifications. The operating range of the CPU (Tj) is 0 to 105C.
FWIW, current thinking on disk reliability is that relative humidity is a more important factor than temperature. Though I wouldn't want my disks to run anywhere close to 65C myself. One disadvantage of the newer WD101EFAX is that it uses more power than the WD100EFAX (and therefore will run hotter than the older model).
The WD disks (including two WD100EFAX) in my main NAS run between 31-36C. Though there are several posts here from folks who's disks are running in the mid 50s. Most are using Seagate drives (which in my experience often do run hotter). But WD101EFAX operating power (8.4 watts) could bring the temps up into that range.
As far as the fan goes, I think the best path is to find the fan model google for it's specs. I'm not seeing any posts here from anyone who replaced it.
