Hi,

I've just purchased an all new pc, and got myself the hard drive listed below. I plan on partitioning part of this to be my windows drive.

I do however have a 4/5 year old 74g raptor drive in my current pc which is still in fantastic working order. I have no idea what to look for in benchmarking hard drives.
Would I still be better off using my new seagate drive with my new rig for windows, or would the old Raptor still come off trumps in terms of performance?

Seagate Barracuda 7200.12 1TB SATA-II 32MB Cache
 
I reckon the Raptor would still have better access times - a 10000rpm drive will always have 0.72x the average latency of a 7200rpm drive, even if the Seagate will be superior in other areas. More importantly, having the OS on the Raptor and using the Seagate for data would allow both drives to be accessed concurrently when needed, rather than seeking across a single partitioned drive.

Having said that, I'd personally ditch the Raptor anyway as they're too noisy for my liking, although you may have other priorities. :)

I recently put my old 2 in raid 0 and installed windows 7 RC, it got me a score of 5.9 in the "experience rating" if that means anything?

I will be going SSD and WD black for storage when the prices settle a bit on SSD's.

Only assuming the firmware to be equal :) In reality there's even different average access times between drives of the same model, differing only in firmware.

The Raptor will, as said, give you better OS performance due to the lower access times but will most likely be noisier.
 
I vouch for the noise!, I originally puchased in late '05 for loading games but due to my old (current) PSU being a "dell" i had to pull them when i changed graphics card, now just making use of them before they are scrap!
 
I had 2 of the 74gb 16mb cache raptors in raid0 for a while, access was nice and nippy but i removed the array as i couldnt stand the noise, went over to a single samsung f1 for my os drive.

hmmm.... being pedantic, I think the average latency will be a simple function of RPM, although admittedly there are other factors contributing to overall access times including firmware optimisations.

It's becoming a bit hard to get excited about mechanical HDD performance in any case, with the advances in SSDs... I've always found it amazing that they work at all when you consider what's going on under the bonnet, let alone keep chugging along for years, but at the end of the day they're essentially blacksmith technology whose time is coming to an end (although perhaps not for a few years yet). :)
 
yeah raptors are NOISY unless they are mounted on rubber grommits, seriously they make a noise similar to when you walk on gravel only more noisy, esp in windows

Ah, but different RPM drives are used for different purposes and therefore the firmware has different average optimisations :p although if all were used for the same purpose, then average latency would be more directly proportional to RPM!

Indeed, they're pretty fancy pieces of equipment really..
 
I've got an old 10k RPM raptor which, admittedly, has a power on time of 3.2 years. I just got a 5400 rpm samsung 1tb device, (note the differences in temperatures) so thought I'd run some HD tests. I might be reading this wrong, but the raptor appears terrible - what do you guys think?

Compared to the 1tb samsung:

Is this normal for a raptor? If not, is it due to age or something else?
 
Looks normal, unless I'm missing something. You have lower sequential read/write speeds because the platter density is much lower, but the important thing is the seek times - that's what makes the OS feel 'snappy'.
