Several Questions about hard drives!

post #1 of 6
Thread Starter 
Hey there. As mentioned, I have several questions in regards to hard drives. I am going to be placing an order on Newegg and will be purchasing a hard drive for a backup/secondary build. My question is, I currently have a 7200 RPM 500GB Seagate 3Gb/s 16MB cache. My question is, will a 5900 RPM drive at 6.0 Gb/s be a better option then a 7200 RPM at 3.0 Gb/s.

I am currently looking at this. Both are 16MB cache.

My second question is regarding hard drive cache. How important is cache to a hard drive's performance. I was also looking at this. This drive has 64MB cache versus the 16MB of the other 2 drives, however it only operates at 5900 RPM. Which drive is a better buy?

I am tight on funds and simply can not/do not wish to purchase a solid state drive.

The 7200 rpm is better, no hard drive can max out the SATA 2 speed which is 3Gb/s, so SATA 2 and SATA 3 (6Gb/s) doesn't have any difference when it comes to hard drives. Cache is like the RAM of hard drives, data's will be stored there for a quicker access, more cache the better.

What matters more, RPM speed or cache?

Depends on how you are gonna use the hard drive

RPM > Cache

There have been tests where 16 mb and 32 mb perform similarly

Also with MECHANICAL HDs doesn't matter if sata 2 or sata 3 (only SSDs truly benefit from Sata 3)
