NONE of those benchmarks seem to be testing the NEW (740ADFD) 74 GB drive with 16 mb cache or the NEW (360ADFD) 36 GB drive with 16 mb cache. In fact they all seem to be testing the 150 GB Raptor against the older 74 GB and 36 GB versions of the Raptor that used 8 MB cache and slower drive electronics as per the access times.

I am talking about the NEW ADFD versions of the Raptor that come in 74 GB as well as 36 GB versions and use 16 MB cache. The names are as follows: WD740ADFD, WD360ADFD.

http://www.wdc.com/en/products/products.asp?driveid=245&language=en

we know what you are talking about - why don't you go buy the 74 and 36GB version and do your own bechmark and then return the one that is slower

 

[Rubycon]

I guess the only way to tell is B&T. (Buy and Test)

I don't know how the onboard SATA controllers treat it but I can tell you a bunch of SAS or U320 drives of smaller size striped absolutely flies. Good thing we're required to attach our hardware to the table or it would fly away - even in port!

Sure there's a risk if one drops off but it's like racing and if you know the risk, you play safe and protect your assets.

Are you retarded? People have explained MULTIPLE times that the 150GB is the fastest...

 

[Arcanedeath]

The 150 is the fastest because it has the densest platters (or the same as the 74gb raptor) also It has higher capisitly so it tends to have better seek times for localized data due to the heads having to move less distance vs a drive w/ lower capasity.

This is what everyone is trying to get through your head, MS Dawn just gave you an example of how the 36GB raptor might reach the same speed as the 74GB, but thats not how it works.

The largest and fastest drive is the Seagate Cheetah U320, 300GB, 10000 RPM.

if we are talking scsi i would go the 15k.4 cheeata, u320, 300GB 15k

forgot about that one...

sorry, i meant the 15k.5

 

[drewintheav]

Does anybody have the new 36 GB Raptor that uses 16 MB cache? (WD3600ADFD)

 

[ManBearPig]

just curious, lets say the 150 and the 74 use the same size platters (roughly), wouldnt it be faster for the reading head to read stuff of the 74, because its just one? or is there one reading head per platter?

also, it kinda seems like this is all moot...wouldnt it be faster to find things on a 36 gb platter because there is less stuff?

 

[drewintheav]

LOL good point!

Ok everyone just STFU.

I'm saddened and profoundly disappointed by people who are even talking about storage here. This was the forums where everyone told me to STFU when I pointed out Seagate 7200.8s were unreliable, even when SR's database pointed them out as teh biggest POSes in the world. Yet people and their fanboism managed to quiet me down.

FIRST OF ALL,

I do have a WD Raptor 74GB ADFD, and I have seen benches and I have run benches against the 150GB drive. The 74gb actually wins CONSISTENTLY in every single benchmark. By a lot? Not by much.

Now both drives (the 150 and the 74) utilize 74GB platters, so THEORETICALLY it should be the same speed right? All your arguments here are theoretically correct. Yet Seagate 7200.8 250gbs were not the fastest drives despite using short-stroked 133gb platters.. the 400gb came out slightly faster.

So instead of telling everyone the 150GB rules all, why don't you all go check out KNOWLEDGEABLE sources like Storage Review where people bench every single damn 7200.10 to bench the noisy ones against the quiet ones, AAC firmware against AAD firmware, shortstroked against non-short stroked, etc...

The 36GB should be JUST AS FAST as the 74gb, but if its a short stroked one, it will be THE FASTEST DRIVE.

There are no shortstroked 36GB ADFDs? Maybe not, but do you really know? Yes it is more expensive to manucature, but what do you think they do with the bad 74GB drives? Toss them? Obviously not... Why do you think we have shortstroked 250GB drives by Seagate and shortstroked 400GB drives? Why do you think AMD X2 3800+s that could have been X2 4400s?

Are you fvcking retarded? This is not hte old 36GB Raptor, so shut up. Go look at benches before you talk.

 

[imaheadcase]

Lets name call and not post benchmarks that makes you right. lol

I just tested it to, and the 2.1gig HD on on my win95 box just beat the raptor by %130, I contacted the manufactor and they claimed it was cause they have a voodoo doctor that puts spells on them to increase speed before shipped to customer. This of course is all fact because I say so, as i go unchallenged in my findings, I therefore win.

 

[drewintheav]

It seems like MS Dawn and DeLerium have at least put some thought into what they said. Where is everybody else's benchies? What DeLerium is saying is exactly what I was wondering about to begin with! The 36 GB (ADFD version) Raptor could be the fastest Raptor. Why would WD produce a unique platter just for the new 36 GB version? That would cost them more so it wouldn't really make any sense.

You are like a broken record ya know!

READ what everyone else and myself type

Raptor 36 Gig = 1x Link We believe that this uses a SINGLE PLATTER. That way we narrow it down to either 36.7 Gig or 74 Gig platter sizes.
Now it is possible for the 36.7 Gig Raptor to use a 74 Gig drive that is short stroked (Half of the drive is essentially disabled). Which means that it would have the same platter density as the 74Gig which would render it the same speed as the density is the same. This however is VERY unlikely.

The 74 Gig platters are far too expensive for WD to just disable half of it (or use damaged ones). Therefore it is very likely that they use a 36.7 Gig platter. This means that since the physical size of the platter remains unchanged in order to occupy the entire physical dimensions of the platter they density must be lower. This results in slightly slower access times and what not because the drives contents are spaced farther apart.

ARE YOU FOLLOWING THIS AT ALL.

The 150 Gig Raptor is also unlikely to be the fastest. It uses 2x 75 Gig platters to attain its 150 Gig. That means that there is another head reading. So therefore if part of the data is on one platter, and part is on the other platter, it will have to switch heads which will result in it being slower.

Therefore, though marginally, the 74 Gig Raptor should, be the fastest (marginally) of all 3 with the 150Gig most probably beating the 36.7 Gig Raptor out.

Now please end this useless broken record crap and find something else to do.

Does anybody have a 36 GB ADFD Raptor that they can run some benchies on?

This will allow more than speculation.

Does anybody know what platter the 36 GB Raptor is using for sure?

People are assuming that it uses a different platter, but is actually possible that it is not.

I do not agree that it would nessesarily be more expensive for them to short stroke the same platter that they use in the other ADFD models.

It could actually be less expensive for them to just make one platter and use it in different ways.

I have noticed that the access time specifications are indentical with the 150 Gb Raptor as well as the amount of cache (16 mb).

And to Gamingphreek
You are supposed to be a Christian? so I am going to ask Christ to bless you with a positive and constructive attitude and also that you might choose to communicate in a more respectful way and not be condescending or patronizing in your responses.

the end result is that you should buy whichever one you need because you will never notice the difference between the speeds in the real world

Do you even know what the word speculation means. We are not speculating here except for platter size.

And yes it would be more expensive to make a 74 Gig platter instead of a 36 Gig platter. You can not agree all you want, but that is fact buddy. (And to further solidfy this, they use the same platter in the new ADFD version that they use in the old version which was a 36.7 Gig platter (seeing as the old version 2 is still produced).

The access times are the same for all of them because it is the Raptor in general that they are defining the specs for. Notice all the weights are the same too which is impossible since the 150Gig has 2x platters.

I dont know why you are so obsessed with this. You have had 20 people tell you the exact same thing. Listen to one of us, if one of us had any doubts than we would run benches, but all of us KNOW which one it is going to be. READ WHAT WE WRITE (And look up the definition of speculation).

I would prefer if you kept my religion out of this. It has nothing to do with this discussion all of your little comments within that are wrong (I never insulted you I told you to read what we wrote, which apparently didn't sink it). Also being Christian doesn't mean I will answer you any different than if i were Muslim, Buddhist, Deist etc...

You insist you are not speculating, but then you do speculate about the 'exact thing' that would make the 36 GB ADFD version faster than or around the same speed as the 150 GB Raptor. (short stroked platter)

You are obviously "keeping your religion out of this" because you are acting like such a hypocrite. Even your supposed statements of fact are hypocritical. You are being condescending and patronizing not Christian-like at all. If you don't like someone bringing up Christianity, (which by the way does NOT belong to YOU) then why not take it out of your tag line. Instead of Christian why not say "HYPOCRITE".

This is ridiculous.

WE ARE NOT SPECULATING ANYMORE. The old generation 2 36.7 Gig Raptor is still in production with 36.7 Gig platters. Therefore since they are still created for that one there is no reason for them to create excess 74 Gig platters which are significantly more expensive.

I said keep my religion out of this I am more than happy to discuss religion for the sake of it. I do not however want you or anyone else praising me or penalizing me for it in a discussion which has absolutely nothing to do with religion!!

 

[Gamingphreek]

It doesn't work that way. Since the platter size is 1 36GB platter on the 36GB version, the 150GB version uses 1 150GB platter(I presume?). Because of this, the higher the size, the faster the read is because theres more data packed into a smaller space, and it doesn't have to go around as far to read the same amount of data. Thus, the 150GB would be faster.*

Note*: This assumes that cache sizes and RPM speeds are the same, so don't attempt to say the 750GB Seagates are faster than raptors.

Here is the first person.

I already explained. The 36GB won't be faster. the 150GB has more space in a smaller area, thus every revolution it goes over more data than the 36GB would, thus the 150GB is faster.

#2

Newest 74 GB is slightly better than the 150, which is better than the 36.

#3

Ok, my last reply, if you get it good, if you dont too bad.

36GB raptor = ONE 36GB platter
74GB raptor = ONE 74GB platter
150GB raptor = TWO 75GB platters

ASSUMING ALL 16MB cache

the 150GB will be faster at EVERYTHING because it has higher density platter (75GB vs 74 vs 36) but mostly because it has 2 reading heads moving at the same time as opposed to the other drives which have one. The 74GB drive somes very close to it in benchmarks (the 150GB generally performs 10-15% better), and actually beats it sometimes in latency benchmarks (like I told you, it all depends where the files are placed on the platter). The 36GB drive falls far below because it has much lower platter density. Even thou it spins at 10k it only comes across so much data.

Think of it this way, if you have a saw moving at 10k RPM, and you have 100 pieces of wood to cut, which way are you gonna get them done faster, by cutting them one at a time, or 2 at a time? Double density = double the data the heads spin on top of.

#4

I think you don't have a clue about hard drives, which is not a crime/sin, but you would be much better off reading theintroductory guide to Hard drive technology on the storage review site than asking questions here that you don't have the background knowledge to understand the answers to.

If you're too lazy here's the short version:

The 74 uses one platter of 74GB, the 150 uses two of these platters, identical platters, just two of them. I don't know about the 36GB drive, nor do i really care. However they do it it's not going to be as quick as even the 74 model.

#5

It does not use a short stroked 74GB platter. That would be more expensive for WD to manufacture. It uses the same 36GB platter that the old 36GB raptor used.

This is what everyone is trying to get through your head, MS Dawn just gave you an example of how the 36GB raptor might reach the same speed as the 74GB, but thats not how it works.

The largest and fastest drive is the Seagate Cheetah U320, 300GB, 10000 RPM.

#6

we know what you are talking about - why don't you go buy the 74 and 36GB version and do your own bechmark and then return the one that is slower

#7

The 150 is the fastest because it has the densest platters (or the same as the 74gb raptor) also It has higher capisitly so it tends to have better seek times for localized data due to the heads having to move less distance vs a drive w/ lower capasity.

#8

And then all of my quotes.

And then to put an end to the short stroke idea, I just said that they still make Generation 2 36.7 Gig Raptors which have been reviewed and have been shown to use a single 36.7 Gig platter. Since those drives are still in production it makes no sense for them to use 74 Gig platters when they just use the same platters as another drive.

Finally, regardless of what platter they are all going to be so close to each other you will never be able to tell the difference.

* In your last communication you did not directly insult me or talk down to me just because I had a different opinion and I do appreciate this.

* You simply stated your opinion.

I understand your point (if it is true) that the 8MB cache version of the 36 GB Raptor might still be in production.

I would still like to know for sure what the actual case is.

What platter does the ADFD version of the 36 GB Raptor with 16 MB cache (actually) use?

I will try to call WD next week. Maybe Tech Support will know?

Storage Review normally has the most extensive reviews of hard drives. It is an excellent site and has been around for years and years.

http://www.storagereview.com/

You will want to go to their "performance database". There you find a drop down menu where you can select various tests and look at the results for all of the extensive collection of drives they have tested.

I would add that the question of "what is the fastest hard drive" can all too frequently turn into "to do what?" If you are using a drive for backup, you want a drive with fast write capabilities, since you rarely read a backup disk. For normal C: drive usage you probably want a drive that has a good balance of read and write speeds. For these , I would refer you to the "average random access read test" and the "average random access write test" as well as the "maximum transfer read" and "maximum transfer write" tests. Additionally, if you are a "noise freak", you could check out the 'idle noise" test. If you are a gamer, you would be interested in the comparisons at various games.

Good luck in your quest!

 

[MplsBob]

I have both 36 & 74 GB raptors. I strongly prefer the 74gb units. While there are differences between the various 150gb units and the 74gb units, they aren't particualrly significant. The biggest change will come from going to the Raptor line in the first place, but the differences between the upper Raptors is not particularly noticable.

The question of 74GB vs 150GB actually can rest on a whole lot of factors, how you are fixed for money, how badly you need the larger capacity, how you use your computer, etc, etc, etc. If money is no object, go with the 150gb unit. It will last you for a longer period of time before you fill it up.

There are no results at www.storagereview.com for the 36 Gb (ADFD version with 16 mb cache).

This might be because this 36 Gb Raptor (ADFD version) is the newest Raptor to come out.
