Whats The Fastest Harddrive in Real Life?

I read a review somewhere that 250 gig 5400rpm hdds were faster than 20 gig 7200rpm hdds.

Im selling my Segate 80 gig satas tomorrow and will need to replace them. I dont have tons of stuff on my comp so I dont need big HDD's. But if their faster I would consider them.

Would it be better to get a Raptor 150 or a pair of 16mb buffer hdd's? (no reviews yet on really new stuff)

How about scsi and 15k rpm hdds?

All I am concerned with is speed. The failure rate is of NO CONCERN...



You have two choices:
1. Knock off the hostility.
2. Post on another forum.
Which will it be?

Well if you got the money, scsi and 15k rpm drives in a raid 0 config should be pretty damn fast.

But raptors in raid 0 are really good and not too expensive. Of course, a lot of people will point out that raid0 raptors aren't significantly faster than raptor as a single drive config (I think there's a review here on anandtech to that point) but if you don't care about failure rate and you got the cash, why not?
 
What do you want to do with them and what's the budget.

SCSI is only a good idea for servers or if you've got the bits very cheap. Raptors are only a good idea if you've more money than sense (😉). RAID0 is only a good idea for those who stick massive files into photoshop or video/audio work.

Hell you might be best off with a RAID0 array of 15K fugitsu MAU 147GB drives, but for most people that's a bad buy indeed.
 
Hey Bob, SPEED! thats it.
Thats all I am concerned with. Some say Raptors rule some like u say they dont.

What I want is whats fastest from people who care. If Fast dosent matter to you go to another post and share your advise there.

Absolute fastest will be latest-gen 15KRPM SCSI drives. For server tasks, nothing else will come close.

150GB 10KRPM Raptors are pretty close to the SCSI drives for desktop tasks and cost a hell of a lot less.

Latest-gen 7200RPM 16MB SATA drives are not a whole lot slower than the Raptors on the desktop (they're comparable in some cases to the 74GB Raptors, and often beat the first-gen 36GB Raptors!) They're usually about a quarter the price per GB of the Raptors, and come in up to 500GB capacities.

RAID0 will always be 'faster' than a single disk, but it's usually a marginal improvement overall for desktop work. Where it mostly helps is with working with VERY big files (creating or editing huge audio/video/image files, for instance), and when doing very heavy multitasking (since it can service multiple I/Os simultaneously).
 
Just to mention, there are two types of speed:

Low Latency, and High Bandwidth.

For desktops, Raptors win at Low Latency (response time)

Raid + Big Hard drives win at High Bandwidth (how fast data can be read)


I prefer the response time benefit of the raptor, which often doesn't show up in benchmarks. However, some games (when loading) read a whole lot of data, which will give the edge towards high bandwidth drives.
 
the cool thing about raid0 is u lose no space.

so if u have 1 hd and you want more all u got to do is buy another of the same hdd and now you doubled ur space and you can also put them in raid0 for more speed.

NO DOWNSIDE

PS Its NOT 2 times faster, but still its faster in Raid0

There is a SERIOUS downside. One error or drive failure will nuke the data on both drives, and the array will be unrecoverable.

And you are right that it is not 2X faster, and in most cases is not even 1.1X faster in most desktop usage.

What you might not know is that it is MORE than 2X likely for you to have an issue on a RAID0 array than on a single drive. The error potential is not 2X, it is exponentially higher, although I cannot give you the exact formula for computing it. Each drive you add further exponentially increases the risk.
 
ChiPCGuy we had this discussion before at length. Lets just agree to disagree.

I find it hard to believe that all the mobo mfg. would waste the space on raid if it was of no benifit.

I have NEVER lost a HDD in a raid array (i been using then for 3 years so far)

Agreed. We agree to disagree.

One thing, though. A gambler who consistently beats the odds is still gambling. I have had RAID5 arrays go down.

Just how big is that chip on your shoulder???? You are totally unwilling to consider alternatives and options and listen to some folks who have been in the IT field for 20+ years.

If you want FAST, then spring for a Raptor 150. If you want to go a little faster and don't mind risking your data, then buy two and put them in RAID0. If you want FAST and RELATIVELY safer, then RAID 0+1 with FOUR Raptor 150's would be the ticket. If you want to WASTE your money, then spend them on 15K SCSI drives as they are not optimized for a desktop environment and in desktop apps most 15K SCSI drives are blown off the map by a pedestrian 7200rpm SATA 150 HDD.

Or...perhaps you should spend that cash you are considering on a RAID0 array on some therapy instead.

I read the first post and I also read this.

You are making friends like crazy on here.

Obviously, I don't know you, for all I know you are a great guy. If you want to participate in the forums, you'll have to tone it down or no one will be interested in helping you out.

yosuke188 wasn't trying to piss you off, he felt he did have something to contribute; he felt your money would be better spent on other hardware for overall performance instead of high end HDD. If this isn't a route you are interested in, ignore his post or just say "I?m happy with the rest of my hardware, just looking for insight on fast hard drives". Posting what you did just rubs people the wrong way and turns your thread into a flame war.

On topic, I'd stick to a raptor 150. A 15k SCSI would probably be the fastest, but I don't think it would be worth the cost of the drive(s) or the controller. As for Raid0, if you've got the cash and aren't worried about drive failure (which you clearly are not), then I say go for it.

QFT. Also, see the below link:

http://www.storagereview.com/comparison.html

15K SCSI units are an ABSOLUTE waste of money. The firmware in a server oriented drive is optimized for random out-of-sequence accesses and nothing else. Even a Hitachi 7K500 pwns the best 15K SCSI unit in a desktop pattern.

Totally agreed on the Raptor 150....look what tops the charts in the above link 🙂

Edited because my stupid link showed the older test results without the Raptor 150....you will have to hit sort on the SR Office DriveMark 2006 results to see what I mean.
 
Nick5324 I am way too old to care about friends. I am here to help and if its not needed I will leave.

As to flaming I suggest that People stick to the post and if they have nothing useful to say they read and LEAVE..

As to that post you brought up I was trying to let people know that I thought $85 was WAY TOO high. Why morons took it upon theirselves to bug me for trying to help shows that there are way too many people who suck on this forum.

If people are too stupid to figure that I am trying to be helpful than F%#K them!

Now as I stated earlier stick to the POST!
