Are Raptors the fastest hard drives?

I've been out of the loop with hard drives.

What's the standard speed of hard drives nowadays?

What's the fastest out there?


How much of a performance difference is there between the standard and fastest?



And does it really make a difference?
 
Standard is 7200 rpm, Raptors are the fastest no doubt, although 7200rpms are closing in sequential speed, which is not dominant factor for everyday use.

Difference is subjective and depends of application of use

 
Short answer: No.

Long answer: pretty much.

As far as affordable non-SCSI drives go, yeah, they are pretty much the top.

However, not only do SCSI and SSDs leave them in the dust, their cost has come down considerably.
 
The fastest drives out are still 15k drives but they are mad expensive and use scsi interface, the raptors are 10k drives sata or ide depending on what era u get..

Rapters are also optimised for desktop use which entails frequent switching from read to write & back again while most SCSI drives are intended for server use & while they have considerably higher performance then any SATA drive for sustained sequential reads/writes, they tend to bog down with frequent switching despite faster RPM's & access times.

Bottom line is that right now the 150mb Rapters are still the fastest desktop drives you can buy, but its a tough call as to wether the small size/high cost is worth the small performance gain over the best 7200rpm models.
 
They are generally the fastest consumer-oriented SATA/IDE desktop hard drives (out of which definition I am excluding solid state drives).

I don't believe that's right... if I remember correctly, WD's aim for the Raptor was a cheaper enterprise drive that could phase out SCSI because of the price difference. What they got was an enthusiast drive, because it does provide decent speed enhancements, but is still enthusiast because of the poor gb/$ ratio.
 
From some of the more recent drive tests that I've read the newer desktop models are closing the performance gap with the raptors. It won't be long before they catch up to it performance wise unless wd enhances it more. I couldn't justify the price to performance of one so I went with hitachi this time around. Who knows what the market will look like the next time I need drives. With the increased pricing pressure on we I hope that they will become more reasonable with the raptor line.

I don't think you understand difference between sequential read/write and random access. No 7200rpm drive has closed in, try this for Average Random Access Time

More recent drives are catching up in idealized benchmark tests. Put them in the real world, and the Raptor will still have a pretty commanding lead. I don't know about most people, but when I use my computer, I don't wipe my drive clean and reimage the drive with a perfectly defragged image that only has the OS and application(s) I plan on using for that session. In the real world, drives get fragemented and filled with a bunch of stuff that likely has nothing to do with whatever applications you plan on using at any moment. These things will have a dramatic slowing down affect on drives. The low level abilities of the Raptor will deal with these issues significantly better than a 7200RPM drive. Not to mention that a 4/500+ GB drive simply has significantly more capacity to kill off its performance than a Raptor.

The Raptor is still king of the desktop for the forseeable future until WD gets around to releasing a new generation.

i bought my for 120 x3 + 65/gb x12= 1140 for 12 gigs

I wish they'd release some higher-density devices eventually. RAM is getting so cheap . . .

It's amazing what you can find out by actually reading.
