As I understand it, CMR gives better performance than SMR?
depends on use cases.
SMR
pros: energy efficient, more compact
cons: onboard cache, when used up during large file transfers, it slows down.source: https://www.reichelt.com/magazin/en/guide/smr-cmr-which-hard…
Thankyou, that link was a very good explanation. It's confirms what I was thinking, CMR is faster for transfers and regular writes to the drive.
pros: energy efficient,
Roughly 2-5 watts more energy efficient. Disk RPMs have higher impact
more compact
Internal only. Outside they are all standard 3.5"
SMR is economy class disk
these are horribly slow..
barracuda can be had for similar priceLink?
just google it.
Well, it the same rotation speed and only in-store, delivery unavailable
https://www.centrecom.com.au/seagate-barracuda-8tb-5400rpm-3…yea. they look fairly similar in specs. thats true…
i partitioned a blue and copying from partion to partion was really slow. will never buy again.
just sharing my experience, barracuda 8tb is 199$ on amazon, so why would you buy a blue?

Very few drives are good for this sort of thing.
More than happy with my unit. Considerably faster than the 3TB Green it replaced.
@Nilfunds: Copying from one partition to another on the same drive? If so you're never going to have a good time, you're working the drive twice in one go by doing that hence the slow performance.
@Nilfunds: Was it specifically this model 'blue' though?
This is one of the first SMR drives in a LONG time; it can't be compared to others on the market currently.
The barracuda probably won't be any better they're SMR drives.
Im maxing out my 10GbE just fine with these.
Have you done much samba/nfs tuning? Or are you trying to use these as a boot drive or such on a local machine?
It has 4 times the cache to make up for the fact they're SMR.
Yeah, that fills in for the write speed to bare metal, until you exhaust it.
And of course im a nerd.
I'm on the internet.
Discussing computer hardware.
In details such as write speed; and you're discussing cache……
Im pretty sure "nerds" is a given.
barracuda is an SMR - yuck
i think you got it backwards mateBarracuda is faster for short writes because larger cache, however for long random writes it basically grinds to a halt.
(ask me how I know?) I run a bunch of the 4tb and 8tb in windows and unraid.i have them both too but i only use them for backup of large files so i only see the downsides of the barracuda
what is considered a "short write"?
all my stuff is sequential (copying tv series folders to it mostly)Sequential is usually fine.
I've had 1/5 fail already though.My use case is the same as your except in an unraid server. In the process of changing to IronWolfs though.
what is considered a "short write"?
Barracuda has 256MB cache. Write anything larger than this and it will show its true horribly slow Speed.
How would this go for a media server?
Always on? This is okay but some would go Reds
I would go with the blues for single drive configuration. Reds designed to use in Raids.
The firmware in reds doesn't know what to do when encounter bad sectors (on purpose). The blue firmware will try to recover and fix the issue.
Also always on = less stress :
a computer with a high uptime may have a lower probability of drive failure than one that has been power cycled routinely

Good to know
With 8tb you can store at least 1600 movies with 5GB each.
I would recommend Plex, it's very easy to use.Or free and option source, Jellyfin media Software
Currently using Plex of my main computer, but I've recently setup an old MacBook as a Linux server as a unifi controller, would like to transition my Plex server to it but I only has a 120 SSD.
Only concern is running this as an external for 40gb brips, should keep up for direct play with no transcode I hope.
Temporarily out of stock for Amazon
I see $203.00 Was: $269.0 Save $66.0
The price for $195 has expired.
Btw, this is CMR hard drive
