SATA Drive Configuration and Selecting your drives
- Which SATA should I buy?
- Are the newer versions faster?
- What is SATA?
I'll be answering several questions about the SATA drives and how you might want to configure them. Big and Fast aren't always the best and sometimes making something small and quick could be good.
Like I said, I'll update this often as I run into new configurations that I think make a system respond better.
When it comes to hard drives we have more today to choose from than we did last year. The Industry Boom SATA 2.0 3Gbps with RAID 0, 1, 5, 10 SATA 2.0 6Gbps with RAID 0, 1 . Just like the USB it seems our designers have the full duplex roll handled.
Kind of like splitting a processor and calling it dual or quad core then allowing more than one channel out for memory management and the next thing you know we have a cleaner two-way communications method we never had before.
But when it comes to SATA you're going to find allot of manufacturers not listing the versions or the speeds. It's very important today to always look ahead and make sure what you are buying is right for your application and hardware.
My guess is you are looking at new equipment now. Then it's Faster is Better for hard drives. Small is also better if you can increase your seek ms times.
Basically you want a hard drive to be able to find your data quickly and that relates to RPM's, and Seek time. If it's found fast and the RPMs allow for quick extraction then you are moving fast. The larger the Cache also helps when you are reading and writing data. The drive attempts to keep things in cache for you if you access the same data often. (Just my brief summary. There is a more technical description.)
Now that we have faster and faster SATA and most coming with RAID 0 or 1 we can see that 2 or more drives can be set to act as a single hard drive or we can use 2 drives of equal size to make a mirror image of our primary working drive in case one fails we can keep working.
But then walks in the RAID 5 and 10 setups. Now we are talking speed, redundancy and backup. Our computer just became more complicated than switching from DOS to Windows 3.1 or for the newer age it would be like moving from Windows 7 to Windows NT4. (Or was that the other way around. )
Be sure when you are looking at new Desktop computers you have at least 2 channels of the SATA 2.0 6Gbps drive adapters with RAID 0,1 or more. That will set you up for some upgrades in the years to come. RAID has been around for many years so don't think it's new technology. Basically it just hasn't been that affordable to consumers in a Hardware configuration. Software RAID is affordable but must slower than a hardware setup.
