Ram and Hard Disk RPM

What is the different between DDR, RD

and for a hard disk, what are the good RPM?? and what are the fastest?

7200 RPM is good i believe 10,000 is the fastest right now but i tihink it's only avaliable in a 18gig hd right now.


I know the difference it's just that i don't know how to descibe it....but every body here probably knows so they'll tell you a much better explanation. I believe RD is faster than DDR but DDR is more used and more stable......but then again don't depend on me...i ama dunce when it comes to computers

If you're about to by a new harddrive, I'd strongly suggest getting Western Digital's new Raptor series. The first IDE drives ever to run at 10,000 RPM Last I recall they come in capacities of 36GB (though this may increase soon enough). However, you'll need a Serial ATA interface to use this drive. By doing this you'll be able to have a 10K RPM drive without going SCSI, which is a very expensive alternative. SCSI drives are available in up to 15,000 RPM

I would recommend this for reasons of performance. Now if you're a storage freak who likes to horde data and never delete files, I'd suggest one of Sea Gate's newer models. They should have a 200 gig, or more drive, soon enough at 7,200 RPM (heck, they may already have one out that exceeds 200 gigs). If you go this route, make sure to specify 8MB cache.

As for RDRAM (also known as Rambus), this is a bad choice right now, you'll want to get DDR RAM. I can't say more than this without getting into a really long post, and other matters require my attention now LOL

Maxtor has a 250 gig hd i believe

 

They'll have 300GB drives soon, if not already. I wouldn't go with Maxtor because their new DiamondMax models have terribly slow write speeds due to their automatic data verification process (like 13MB per second LOL) - also Maxtor drives are not exactly known for their reliability, as in some drives just dying for apparently no reason after a short period of time. Until the recent surge of serial ATA, they did have the advantage of ATA 133

 

Are 10000 RPM drives worth the extra $200 you put down for them? Is the speed that noticeable? I doubt it. The speed of a hard drive does not make create a noticeable bottleneck.

With 2 maxtors drives and 1 seagate drive I can't even tell a difference between the 3 of them. I have never had ANY problems with maxtor drives and I will continue to buy maxtor drives because they have been so reliable.

 

Extra $200? There are Raptor drives for sale at cheaper prices than some 7200 RPM drives, and they are going for less than 200 by themselves.

Have a look here. They've got a Raptor drive for 147, while a 200GB, 7200 RPM drive cost 233.

The speed difference is quite noticable. Haven't you even bothered to look at any benchmarks?

Well I don't think comparing the prices of two COMPLETELY different sized drives makes much sense. If you compare the price of a 36 gig 10,000 RPM drive to a 36 gig 7,200 RPM drive there is no chance that the slower drive will cost more. If anything the difference should be $100+.

Benchmarks

As you can see the WD2500JB, a Western Digital 7,200 RPM Drive even out performed the 10,000 RPM drive in many areas (although it got it's ass kicked on the CPU utilization). The SCSI Maxtor drive out performed all of the drives in two out of the 3 tests. By looking at this I would hardly spend an extra $100 or even $50 on the "faster" hard drive.

I guess if I had lots of money to throw around I might consider purchasing a 10,000 RPM drive. But I don't. So I wouldn't.
