Slow HDDs

Danno

Why is every 1tb Hard Disk Drive so damn slow? Brand new laptop, few months old laptop, a year or two old laptop - it makes no difference; they are just pure fcuking junk.

Because you should have an SSD instead.

2.5" 5400rpm HDD's that are used in laptops are just slow. 7200 RPM 3.5" drives are better. SSD's much better again.

No idea why new laptops are still being sold with those ****ty HDD's though.

Because your average punter who goes into Curry's to get a laptop doesn't have a clue. I know i'm generalising a bit but it is what it is.

Not even a bit, it is what it is.

They're also the worst possible setup. A fast drive like you'll see in a database server form factor will be 10mm and probably have 4 platters, 7mm laptop drives are cramming all their data onto 2 platters. Slower IO by less heads, slower to hit power targets. Slower because read retries happen far more due to cramming data into less area and relying on ECC to sort it.


As above, like buying a horse and cart for your commute. Just don't.

You bought a laptop with bad cpu also not enough memory also junk the computer seller puts on it you need to download a newvinstal of windows on USB stick from Microsoft and do a new install
Then you need ssd or nvme drive

More platters is bad, at least in the desktop space. They only read from 1 head at a time and they are far more prone to failure.

You want a single platter drive which maxes at 2TB at 3.5" afaik. That also happens to be the best price/performance and size hard drive.

Get out of here Bobby, where do you get this nonsense?

Nope. The controller writes sequential blocks on parallel tracks so reading in and out happens concurrently.

You much rather more platters with larger cells on the surface than one platter with them packed it. Sure look what SMR is doing, they're overlapping your data to squeeeeze it in hammering performance. High density is your enemy.

Alright maybe my knowledge (or yours) is a bit outdated here but afaik that only reduces seek times but not by much, reads are still only done 1 head at a time on most consumer HDD's.

Those are niche examples. I'm talking about your average consumer HDD in a laptop or PC. Multi platter is not the way to go.

Thanks for all the replies folks.

After all the waffle,
Buy an SSD..
Sorted.
