Is it possible to put 10k hdd, like velociraptor in a laptop? specifically the Sager 8690.
some 10k drives are sata III, but i didn't see that available in laptops, so that won't work, but idk if the 10k drive is possible or not?

Thanks!

Not really, primarily because most 10k drives I've seen are 3.5" form factor. I have yet to see any drives faster than 7200 that are in 2.5", not to mention that 10k drives are horrible with regards to power.

Best bet for you is to buy a cheap ssd and put it in there. Better than 10k drive anyday.
 
VelociRaptors might be in 2.5" form (and 9.5mm tall) but they require 12VDC on the power rails, and standard SATA power is 5VDC so no, it ain't happening. If you attempt to put one in a laptop when you power it up it's going to most likely kill the SATA controller in the laptop or even worse so, don't do it... :)

And yes, if you're that concerned with performance in a laptop form factor drive, an SSD is the only viable option. The best laptop drives you'll find nowadays are the Hitachi 7200 rpm 7K500 series models, overall - the WD 320GB Scorpios win in some aspects (like 3 tests out of 20) so that makes the Hitachi's the best overall. Plus, you can usually find the Hitachi 7K500 drives at about $60-70 while the WD 320GB Scorpios command over $90 most of the time - they cost more and offer less space and less performance in most respects compared to the Hitachi drives.
 
Thanks,
I had found that 2.5" velociraptor under laptop section at Newegg, so i thought it might be a possibility.

re: SSD's; The read performance is very fast yes? But isn't write performance actually slower than a 7200 standard drive?

As recent as couple of years ago, this was true, especially for random 4k writes. Now, however, any of the modern high-performance SSDs will absolutely dominate a traditional HDDs in every aspect (aside from $/GB, of course). A SSD's performance is largely dependent on which controller chip is being used, and the two top controllers right now are Sandforce SF1200 and the Micron C300. There are a variety of OEMs providing Sandforce drives like OCZ, Corsair, Super-Talent, etc. Crucial is the only company providing SSDs with the Micron controller, which is no surprise (Crucial is owned by Micron).

The standard SATA power plug includes 12v, 5v, and 3.3v rails. It's possible notebooks might not energize the 12v rail if normal laptop drives don't use it; bu that's not what you said.
 
The fastest non-10K physical hard drive as of today is most likely that brand new WD 500GB WD5000BEKT drive. HDTune scores put it at 110MB/s max read speed and an average of about 85MB/s from start to finish with ~15ms access times so, it's pretty damned fast. Only place I could locate one in stock is at Buy.com:

http://www.buy.com/prod/western-dig...-hard-drive-7200-rpm/q/loc/101/216500065.html

$77 bucks or so with free shipping ain't bad considering it's the fastest laptop hard drive you can get... I didn't even know WD had done a 500GB until a few minutes ago when I read about it over at NotebookReview.com.

Will probably grab one myself at some point here in the near future and find a 2.5" eSATA enclosure for the 250GB Hitachi I presently use.
