Confused with WD Black Prices

[XSnPX]

Hi all,
I am looking to add another 4TB Black drive to my system, however when searching I am seeing prices and model numbers that change the price quite considerable: for e.g
the 4TB model WD4003FZEX is around 330€
the 4TB model WD4004FZWX is around 180€
and recently just saw the
6TB model WD6002FZWX is around 210€
6TB model WD6003FZBX is around 280€

I tried to get specs on google for each model and they all say the same specs

Thanks

Ben

So Western Digital doesn't list the first model in your list on the Black datasheet -- https://www.wdc.com/content/dam/wdc/website/downloadable_assets/eng/spec_data_sheet/2879-771434.pdf They show the 2TB version but not the 4.
Newegg lists the first part number as obsolete. That could explain the pricing. An old (obsolete) price.

Personally I would ignore part numbers that aren't listed on the datasheet above.

Thank you for the quick response,
So after more research this is what I am seeing:
6TB - wd6003fzbx - 272€ - seems this has 256mg cache - but specs vary in listings which is worrying
6TB - wd6002fzwx - 240€ - seems to be 128mg
4TB - wd4005fzbx - 204€ - this seems to be 256mg
4TB - wd4004fzwx - 209€ - this seems to be 128mg
Information above taken from the WD website - adding to cart shows model reference.

Now if i look to buy the model ref above - both 4TB state 128mg - and also both 6TH state 128mg

Not easy, and sorry if I am being pedantic on this, but would be great to know what I am buying too - and what would you recommend - lookign for 4Th and or 6TB depending on Price, will act for extra storage mostly video media and on 24/7

Thank you again

Ben

You won't see any real-world differences. Might there be a difference in a specific benchmark? Sure. Will that make a difference in watching a video off the disk or editing photos? No. Stop obsessing about minutia.

With this i guess buy the cheapest 6TB then
