Hard drive cache


#1

I am planning to buy a new hard drive so wanted to ask how does the hard drive cache effect in the performance. is it good to go for 8 MB cache ? is it better then the 2MB cache hard drives? how exactly is it good

thanks


#2

I must add the last time i bought a hard drive, (5 years ago i guess) i don't remember anything such as cache on hard drives

dear bro!

as u may know the cache is the temporary memory where the data goes before being finally stacked in its final place.

a good cache definitely helps in the speed of hard drives. i bought a western digital 2 years ago, and went for an 8mb cache.

how will it effect you? ok...lets see..u may not be able to feel a huge difference..but benchmarks tests on hard disks with a bigger cache are better than others. also, you can feel the difference when copying large files to your drive.

i hope that helps you.

i see, thanks for the info

so the rule is the larger the cache the better it is, hmmm

16MB cache is common on good drives these days. 8MB has become old... sort of. Any way, it all depends on your budget. If you can afford it, always get the highest disk space followed by highest amount of cache memory and RPM available.

SATA/IDE decision depends on his main board.

I dont have sata on my mainboard. i was thinking of going for the seagate barracuda 320GB with 16mb cache. selling for 5500 i think

That’s a nice one. Things would get better if your mainboard supported SATA.

u can use sata-to-ide converter if u like...for the time being.

Hey What Sata-II Hard disk i get ? i need 160gb...seagate or western digital ?

does that work perfectly? i dont want any increased response times because of the converter

Hail Western Digital!

let me tell u in short... go to ur boot page.. see if theres cache option.. disable or close it.. then just go start ur widows and u are gona cry tht y is it so slow with my 2 Gb ram 3ghz processor... lol.. u know what i am saying..like the others said the biger the cache the beter the perfomance. and Raid and SATA should be ur primary options but never mind.. ide for u :)

Here's some reference material regarding the benefits of cache in a hard disk:

[quote=", post:, topic:"]
A good empirical example may be found by comparing Western Digital's Caviar WD2000JB (8 MB) with the WD2000BB (2 MB) (cache). As illustrated by the comparison, the 8-megabyte buffer delivers a single-user, desktop machine a 30+% performance gain. T

Regarding sata vs. ide at this point in time hard disks are two slow to take advantage of sata. The fastest hard disk around is still well within the transfer limits of IDE.

Data transfer rates are limited by mechanical hard drives themselves, not the interfaces: the fastest modern desktop hard drives transfer data at a maximum of about 120 MB/s,[2] which is well within the capabilities of even the older PATA/133 specification.
