Raptors

but they get beaten black and blue by the top 7,200RPM drives in terms of transfer rate.

Find me a single 7200 drive that will beat this (76 GB 16 MB cache).

For referance, this is my RAID 0 2X36 GB 8MB cache).

Alright! Alright! ;)

I was wrong, fine. :p

I only repeated what I had been told with regards to that comment - I haven't used a 7,200RPM drive in my PC for well over 2 years now.
 
Hehe. OP if you want a raptor there's 1 B Grade 76 GB one with 16 MB of cache. At £79.89 delivered to your door it's a bloody bargain. I'd be buying it if I had the spare cash.
 
Just done HD Tach on my Raptor 150GB 16MB drive and I get slightly less than you in all departments:

129MB/s burst speed

Random Access 8.0ms

Although the average read and sequential speed are pretty much identical to yours.

Could the other two be Vista drivers maybe?
 
The two at the bottom are my RAID 0 array and that test was done in Vista. The single drive is straigh out of the box brand new and has nothing but OS and basic drivers on. I'd defrag your mate, that might be it. Or your MFT is fragged too.
 
A lot depends on the Sata controler, the above scores area little low, if your on a Sata150 controler you will not get as high a burst and if its only onboard (not onchip in the Southbridge, or is a PCI add in card) it will be limited by the old PCI bus at 133MB/sec shared with other devices, you need it on the PCI-E bus ideally.
 
You're missing the point though in some respects; that many raided drive setups have seek times getting closer to 8ms (often about 11-12 on some I have seen) access times, and will blitz the raptor when it comes to price performance, as you can get higher capacity, with a similar sustained read speed for the same price, ok you lose out on some seek, but the overall price to capacity and sustained transfer isnt worth it. Higher seek times will make lots of minute changes nippier, but at the end of the day, you're also going to benefit heavily from the much larger capacity and higher sustained transfer for the same price.

Will be interesting to see how prices come though when Seagate get thier 10K RPM drives out, if they make the market a lot more competetive then the 10k drives may suddenly become a lot more interesting.

I do NOT miss any point, Raptors in Raid0 if 8-9ms is still faster than 1 SATA300 drives seek never mind 2 SATA300 seeks in Raid0, the OP was not asking about price, price does NOT come into this thread, he asked about perfomance.

I know fine well Raptors are a luxury as I paid £250ish each for my Raptor X's back at launch.

"Thats probably what I am going to do because I cant really justify the spend otherwise"

That sounds to me like he isn't all that keen on the extra cost of the raptors. I think his best bet is just to buy a single 250gb+ 7200rpm drive and see if he is happy with the performance. I'm willing to bet he will be since the gap between them and the raptors isn't as great as some of you seem to imply.
 
Im a Raptor 150gb Owner, and im not that impressed tbph. It cost me £150, but is still the major bottleneck in my system :(

Is it faster than a modern 7200 perpendicular drive? im not entirely sure, but I still find that its sat there crunching away for a long time while the rest of my system waits around. If i had the space in my case, i'd grab another one and try raid0, but since I dont, I guess its about as fast as im gonna get.
 
have used 2 x (old) 36gb ones in raid for OS.
74 gb ones... just about to get a newer 16mb cache one... 150gb
can concur - system just feels snappier and quick...

++ good warranty 5 years
-- expensive for large drives.

the way I would do a system - raptor for OS and games.
sata 'big' drive for backups / data....

my thoughts - overall definately worth it.

Then you will need wait on better Solid State cause the SATA600 that was to come in 2007 does not seem to have appeared and drive spindle speeds would need go up anyhow, I think you will see 15k Raptors if they can keep heat and noise down esp now Seagate poking in 10k Desktop market (if even true).

got 32gig raptor (16 meg cache) in my newbiuld. use it for some games and OS and its faster than my old 7200.9. got it under £40 quid with postage couple months ago from that popular auction site. Wouldn’t buy it from OCuk, nothing against them but i would rather buy 70 quid worth of manure than 36 gig hdd. Still windows installation time took only 8 mins and load times are half than my mates 7200.10s. The only reason I got the raptor is cause I didn’t manage to install windows on my SCSI raid array and that puts raptors to shame with ~180mbs average read. I’d say if you got the money and you are tired of game loading time especially bf2 loading times (in my case anyway) then go for it. Just don’t get the 150 raptor x. I just don’t see why any1 should spend an extra 10 quid for a small window on their hdd.

hope that helps
