    I'm wanting to build a test \ config test setup for 3.5" HDD testing.

    However, the only HDD I have in quantity to perform the tests, and leave setup so I can always re-arrange config, etc.. and rebuild are WD RE 500GB.

    Are these a good test drive to see what I could do in "real world" in which case we're talking 10TB+ capacity drives, or are they too old to give a fair comparison? I haven't kept with up HDD as I'm still using 5TB at home and 4TB for work...

    10TB Gold? or 10TB Red?
    Anyone compared these two when in pools of 14 or more?
    Curious how different they are.

    I have a pool of 14 10HGST drives I could setup and test however you want.

    I would think the 500GB drives would not give you valid real world numbers given the age.

    There are 3 factors that influence hdd performance:
    • the physical size of the platter in the hdd (eg: 1.8", 2.5", 3.5", 5,25")
    • number of platters in one hdd
    • data density on the platters
    Comparing the 500gb to newer 10+ tb hdds will give you wrong numbers.

    I have read a blog that the 10+ tb wd red lost their advantage of lower power/heat and are on par with 7.2k rpm hdds.
    If you don't have to pay for the hdds go with the enterprise versions aka gold :D

    That's true of the smaller sizes, but it looks like the 10TB Red is helium filled.

    From the datasheet: https://media.flixcar.com/f360cdn/Western_Digital-3805661149-eng_spec_data_sheet_2879-800002.pdf

    8TB Red is 5.3W Idle, 8.8W Active (not great)
    10TB Red is 2.8W Idle, 5.7W Active (fantastic!)

    However, the 10TB Gold is not helium filled, and it shows from the datasheet.
    You don't get helium until the 12 and 14TB options in the Gold lineup.

    https://documents.westerndigital.co...wd-gold/product-brief-wd-gold-2579-810192.pdf

    10TB Gold is 8.0W Idle, 9.2W Active (not great)
    12TB Gold is 5.0W Idle, 6.9W Active (very good, but not quite as low power as the 10TB red, mostly due to spindle speed)

    Assuming I didn't care about the warranty differences, I'd take the 10TB Red over the 10TB Gold any day of the week unless you REALLY needed the slightly higher performance of the Gold.

    Great information. Looks like holding out for 12TB GOLD or 14TB is the way to go when ready then :)

    The old 8TB used to be helium but I guess now since they have increased density they can avoid that cost and it not longer is. Look at older WD80EFZX, having said that the new 10TB WD100EFAX is amazing , see how things improve over time...
