Building a new system. Should I go with a SSD drive or a 10,000 rpm hard drive ?

Don't listen to these people claiming that SSDs are faster. SSD is an alternative to moving parts, that doesn't mean it's faster. If you have a laptop, and you want the fastest solution, then SSDs are typically going to be your only option. However, if you have a desktop, you can set up a RAID5 of SCSI drives, for far cheaper. I found a couple of Fujitsu 73-GB 15K SAS HDD 3.5" MAX3073RC for $75 on eBay... RAID5 of 4x SAS would be $300 Australian, FAR faster in transfer speed, more fault resistant and roughly 200GB of storage. You'd be pushing to get a decent 64GB SSD for that price.

My other suggestion is to load your system up with tonnes of RAM and a decent GPU (because both gaming and video editing require this), set up a RAM disk if you need somewhere to store scratch files... and you could get a couple of 1TB cheap SATA drives and RAID those, partition off the first 200GB as that's the fastest part of the drive...

ssd would boot up and run your games more quickly than hdd. but keep in mind that ssd is a lot more expensive than hdd. you can install your os on ssd and run everything else off of your hdd

10 000rpm HDD is a good one. I would probably take the HDD because it's cheaper and you know that it will be fast enough. Although if you buy an SSD it's faster, but it also costs so much.

I vote SSD. I notice a huge performance boost as well as low noise. My PC boots in about 2 to 3 seconds.

I'd recommend the HDD. The SSD will have less storage for too small a speed benefit. Plus the SSDs will cost extra.

What makes ssd drives dramatically faster is their access times. Although the actual speed with copying is really not that much faster. They are quite quiet too. But honestly the capacity of ssd drives are way to small and expensive now. It really isn't worth it.

If you are going directly based off of access and seek times, go with an SSD, as they have close to zero seek times (only a few microseconds). Of course, most SSDs have read and write times many times greater than that of your typical mechanical drive.

I paid about $130 for an OCZ Vertex Turbo 30GB SSD, and it's got a read speed of about 240MBps and a write speed of about 145MBps, quite worth the money if you ask me (GRUB to loaded desktop in seconds).

Also, you can setup a RAID array of SSDs and get really fast transfer speeds, especially if you wait for SATA 6Gbps to become more prominent in the market.

And of course, if you want to go really, REALLY fast, you can purchase a PCI-Express SSD, with read/write speeds clocking close to 1GB per second.

I saw a thing on them they don't have the vibration issues HDD have but no one normaly subjects there comp to tons of shaking. Might be faster cause there is no waiting for physical parts to move.

for me i would go with the HDD... more capacity at a lower cost, a little slower but 10k is rather fast already.

If you're running Windows 7 go with an SSD with TRIM support.
If you're not running Windows 7 then it might be better value for money to go with a 10,000rpm.
