Anyone no how much of a difference these two combos would be as far as performance?

if it's for os and programs you are better of with an ssd
if it's for storage then they are both overkill and you can get 2 samsung f3's 1tb in raid

WD's Raptors still do not show PMR on their specification pages,
even the ones with 6G interfaces:

Take a look at these graphs: PMR also permits tracks
to be much closer together, which appears to explain
the many differences in these graphs:

Those graphs came from this article:

Another, very practical option we have been considering here
is to host the OS on 2 x WD RE4 HDDs with PMR e.g.:

http://www.wdc.com/en/products/products.asp?driveid=831

Transfer Rate (Buffer To Disk) 128 MB/s (Max)


Then, if the speed is not sufficient, those HDDs can be
demoted to data storage. But, the initial prices we've
seen on the Internet make these a price/performance
bargain, particularly in RAID 0 because of the combined
effects of the HDDs' internal caches e.g.:

2 @ 64MB = 128MB HDD cache

Hitachi also got the right idea by adding 64MB cache
to these 2.5" SAS/6G HDDs:

You can put 4 of these in a single 5.25" drive bay,
using the Enhance Tech X14:

Newegg now stocks the Xclio OEM version here:

(pretty much the same unit, upon close examination)


p.s. I can't find the X14 at Newegg today:
it may no longer be stocked by Newegg.

Hmmm...ok....thats good to know. What I have now is an Intel x25-m SSD 160gb for my OS ( win 7)and I'm looking for something fast for storage for games. I dont have to run anything in raid-0 but I figured that would help with my gaming. I built a machine a year ago and used a 80 gb ssd from intel for my OS and 2x 300gb raptors in raid 0 and it worked pretty good. I think my problem then was with vista and first gen intel ssd. The ssd filled up quick and I probably lost quite a bit of performance. Thats why I'm going with 160 gb ssd. I believe the ssd's work way more optimal only about 60-70% full. I could be wrong.

So mayby the hitachis would be better than the raptors but im not sure. So if I was looking for drives just for my games what would be best for the buck keeping in mind I already have the x25-m for the OS. I should have said that before ...sorrry


Also looking at the Hitachis....now that i'm thinking of it. Would 2 of those in raid-0 for games only and a seperate drive just for storage of files be the best? Whats a good drive just for storage of music anf other files. I've never really looked into those. I would assume at least a tera byte would be the way to go.

the benifit your going to see if you get 10000rpm drives instead 7200rpm is loading time that's all anyways get the samsung f3 1tb it beats the velociraptor 300gig in some benchmarks but not the 600gig i mean it isn't worth going with the raptor their overpriced
