RPM vs SATA?

post #1 of 16
Thread Starter 
I was thinking of purchasing this:

http://www.newegg.com/Product/Product.aspx?Item=N82E16822145493

3 TB 5400 RPM Sata 6 Gbps.

Is this faster or slower than my Sata 2 7200 RPM?

Not sure about the cache size of my drive. How do I check w/o prying my PC open?

SATA 3 doesn't bring any speed benefit to a HDD no matter what RPM, it brings a benefit only to an SSD. A SATA2 7200RPM is faster only because 7200RPM disks are usually faster than 5400 RPM disks.

That is good for a storage drive, but not for an OS drive. You want something fast for the OS drive. The RPM is what is most important when it comes to speed.

If I understand correctly, a 7200-10000RPM drive will still be faster even if it is not 6Gbps.

I would rather find something 7200rpm and sata 2 for the same price or less. Sata 3 is pointless when it comes to mechanical discs, I've never seen one saturate 3gb/p, let alone 6gb/s. But at the same time, a lot of mechanical drives are moving to sata 3 just for the title anyway. When I bought my WD Caviar Blacks, the box said Sata 2 but inside the box were actually Sata 3 drives.

All in all, completely ignore Sata 2 versus Sata 3. If the drive you want is the best price and its Sata 3, take it as a bonus. If not, no loss.

SATA 3 means nothing at all for a regular hard drive. Most regular drives still can't use SATA 1 speeds.

That being said, 7200RPM is faster than 5400RPM, regardless.

If you're looking for a new fast OS drive, look into the WD Black 1TB-2TB, or the Samsung F3 1TB. Those are currently the fastest mechanical drives on the market. The 500GB WD Blacks are actually slower though. wink.gif

That will be slower. You only need to worry about the RPM when it comes to HDDs. Go for a 7200RPM or 10000RPM drive. For better speeds you could get 2 2TB drives and RAID them.

Eh, at 10k prices, I'd rather get a small solid state drive to use as a boot drive. At the prices they are now, they are making 10k drives start to become obsolete. At least for most uses that is, there are some uses that would benefit from the extra speed from 7200rpm to 10krpm if you needed the storage.

Not really. Not when the 7200RPM drives such as the WD Black's come very VERY close to the speed of the 10k RPM drives. The only thing the Raptor has over the Black is access time, but its a smaller drive. So just by the Black and short partition it to 300GB (or whatever the Raptor is).

Those are both roughly the same speed. Either will be a solid drive.
