Laptop hard drive - 5400 vs 7200

Question

Hard disks

I needed to buy a new hard drive for my laptop. The beech is quite nimble, therefore the question arose with the choice of a fast screw. There is no money for SSD yet.
Question - how significant is the difference between 5400 and 7200 rpm?
How visible are the differences between 8 and 16 MB of cache?
Write what screw you use in your beech? (If there is advice on a specific model, I will be grateful for it).
Thank you!

Answer 1

Does the 7200 get hotter than the 5400? Far from a fact ... it's the envy of the model.
In my laptop (by the way, for AMD) I changed the WD 5400 to Hitachi 7200.
The temperature of the screw remained the same as it was 38-39 degrees.

Answer 2

Heh, right now the screws are such rubbish. The faster it spins, the faster it dies.
So 5400 is better. Hitach or VD.

Answer 3

5400 - slower, quieter, consumes less power, cooler.
7200 - faster, noisier, consumes more power, heats up more.

Answer 4

7200 heats up more than 5400. I was guided by this when buying, because in my laptop there is a screw inside the palm pad.

Answer 5

7200 really heat up more strongly, if you don’t use a laptop on your knees, then take it, if you do, then 5400 is better.
Yes, and don’t take the WD Blue series, they crumble, especially when the temperature is elevated.

Answer 6

a) One of my screws WD3200BJKT, was taken a long time ago, quiet, reliable. It's hard to say for sure today.
b) Take propellers with acceleration/fall/shock sensors only, without them - lethality, although they are usually + 20% more expensive, but this is the case when the toad needs to be strangled.
c) The difference between 7200 and 5400 , other things being equal , is quite significant. But "other equals" is rare, so you need to look at the tests of specific models before buying. For example, within the same line, WD has different speeds that will let you know very well, but it is useless to compare models from different manufacturers from different years.
d) 16MB cache is much better, but 8MB is not at all dull. Paying extra for 16 makes sense, but hunting for it if there is no suitable model makes no sense.
e) It makes sense to take an SSD in a laptop , they are of course more expensive, but the price difference between a laptop screw and an SSD is much less than between a desktop screw and an SSD. But the difference in speed inspires + incredible resistance to shock / vibration.
f) In the case of taking an SSD into a laptop, it’s not bad to have a screw for backups “somewhere nearby”, SSDs rarely, but sometimes suddenly die.

Answer 7

There is no difference between 5400 and 7200.
It's just spin speed.
What you need to look at -
1. On the OS - if you have W7 or Nix - the expansion of the operative (SuperFetch, disc-cache, commit> N) will help the disk a lot. It gives a LOT.
2. Track access/search speed. You can buy 7200 which can and will copy movies mega fast, but on access to small files (99% of operations) it will be blown away. At the same time, there are a lot of 5400 disks with various intellectual functions (NCQ and other "proprietary" analogues)
3. In general, the cache only affects writing or reading large blocks, in the presence of hard defragmentation, it works as it should.
Summary - I have an SSD at work, a velociraptor at home. When I first put it on, it was SOMETHING. Now, it feels like a terrible brake.

Answer 8

A month ago I changed from 5400 to 7200 in a laptop, it feels like there is a difference, I did not conduct tests.
I also noticed earlier when downloading a large file at high speed, launching a toy in the background, etc. sometimes the music turned off for a couple of seconds, waiting for another piece of the file, now this is not the case.

Answer 9

my macbook pro has 7200wd for 500gb. I was upset that I bought it: it heats up terribly + the noise level has become such that you can hear it at night, but I didn’t notice an increase in speed.

Answer 10

What do you need a laptop for?
Minimum battery life - 5400 for you
Maximum battery life - 7200 for you You
won't notice the difference in speed!
And if you have maximum battery life and maximum interface speed, then you need ssd))

Answer 11

Are you considering an SSD at all? Having bought my first SSD, I realized that I would never return to the railway for the system.

Answer 12

If we take the option with SSD:
I found Toshiba THNS128GG4BBAA 128GB for 5600 and
Samsung 2.5" 128 GB SSD (SATA 3.0 Gbps) Hard Drive OEM for 5400.
Which is better? Which manufacturer is more reliable? Intels are too expensive, IMHO

Answer 13

By the way, which one is better to choose a disk for a laptop if there is an SSD inside the laptop, but its volume is not enough for me (256GB). does it make sense to overpay for 7200?

Answer 14

No option to take 7200! Recently I felt for myself what the speed of 5400 means ... I have not seen this for a long time ...
But if you need it for movies, or store backups there, for example. It’s better to take 5400.
I myself also think that it’s better to leave 1TB for 5400, or 500GB 7200.
