Hello,
Could someone clarify something for me?
My questions are as follows:
What is 6G/s compared to SATA3?
Does a SATA3 hard drive work on SATA2?
What are the cache MB of a hard drive? Is it better to choose a higher rate?
And the last one is this:
I have a motherboard that is about 2 years old and it has SATA2 connectors.
Which one should I take? :O

Thanks in advance because I don't understand anything ^^

Hello,
"What is 6G/s compared to SATA3?"
That's the theoretical maximum speed of SATA 3.0.
"Does a SATA3 hard drive work on SATA2?"
Yes, the SATA standard is backward-compatible: SATA 3.0 will work on SATA II, but you won't benefit from the speed of SATA 3.0 (6Gb/s); you will be limited to the theoretical maximum speed of SATA II, which is 3Gb/s.
"What are the cache MB of a hard drive? Is it better to have a higher rate?"
The cache memory of a hard drive stores the files that the hard drive accesses most frequently so it can access them more quickly (it slightly improves its speed...). On a current hard drive, it all depends on your budget, but 32MB of cache is more than sufficient.
"Which one to choose?"
If you only have the choice between the two you proposed, I recommend this one:

But still give me your maximum budget for buying a hard drive, because the Seagate from GrosBill is a 5900rpm hard drive, which is low considering that the standard for desktop PCs today is 7200rpm.
See you later =)

My maximum budget? Let's say €80, no more ^^ And a minimum of 2TB of storage.
But if I'm connected to an HDD via SATA3, I won't get a speed of (6Gb/s), right?
Even less if I have a 5900 RPM HDD?
Is the difference between 5900 RPM and 7200 RPM huge?
So I need to take into account both RPM and the version of the SATA connector?
And how do I deduce the read or write speed from that? :O
Thanks in advance...

I would like a SATA3 because I think I'll soon switch to a new motherboard that will be equipped with it.
My board only has SATA2, it's an Intel DG33BU.
