What Drive Should I Get? A Guide to the Mechanical HD Market

[Healadin]

Hello,

I am building my NAS and I want to go for Seagate Ironwolf 6TBs. I found two different versions in my area:

ST6000VN0033

ST6000VN0041

I wonder which one is "better".

x33 - has 256 MB cache and 5 platters + 10 heads

x41 - has 128 MB cache and 6 platters + 12 heads

The question is if I should just decide depending on cache size or number of platters also plays an important role?

 

EDIT: x41 is also a bit more expensive (around 20 €)

Cache shouldn't make you buy the unit if you are not working with many apps opened at the same time. The amount of platters differs because density is tending to increase in less sectors, by this you can assume that the one with less platters is a more recent version. You also can see the specs sheet of these two and you will see that the revision number was assigned on different dates: 

June 2017 for ST6000VN0041: https://www.seagate.com/files/www-content/product-content/ironwolf/en-us/docs/100807039d.pdf

 

and 

 

May 2019 for ST6000VN0033: https://www.seagate.com/www-content/product-content/ironwolf/en-us/docs/100807039k.pdf

 

Each time a product is revisited, manufacturers generally change the revision number of that product. In each revision there can be major or small changes as only the design of the label, anyway, I hope this information helps you with something.

Hi, 

I was wondering about that. So would 

MSI Command Center 

Nvidia GFE 

Nvidia Shadowplay 

Steam 

Game 

MSI Afterburner 

HWmonitor 

 

and maybe like 2 or 3 other small apps count as many apps or is a lower cache size still ok for this use case?

Just for Info - WD-Specific:

I've found this (of my opinion very usefull) comparision about the Western-Digital-Rainbow:

WD-Rainbow-Table (pugetsystems.com)

Should i buy a 1TB HDD with 3 years warranty or 3TB HDD refurb with 1 year warranty for the same price? like how bad is a refurb drive?

Nice a short in-depth list of all the current hard drives on the market. Sometimes it's indeed confusing which one to pick, gladly SSHD's aren't really a thing anymore or it would be much more complicated.
