I am about to buy a new mac pro in the coming weeks and just have a question about the wd velociraptor drives. I am thinking about getting one and using that as my boot drive (I have heard these 10k drives are quite quick). I use final cut studio 3 heavily and work mostly with hdv and avchd codecs. I was just wondering if there would be a notable difference between using the velociraptor drive or using a 7200 rpm drive? (WD Black). I am all about saving time on my projects so if there was a significant speed increase (rendering, exporting, converting) I will definately upgrade to the Velociraptor drive. So I was just wondering if anyone has had experience with these drives and specifically if there is an advantage in the video edting realm. Any help would be greatly appreciated! Thank you!

I've been using a velociraptor as my Mac Pro Boot drive for the last year and I think it's terrible. It's very, very loud, and gets hot too. Sure, it's pretty fast, but an Intel X25 could whip it. I am going to sell it and get an X25 as soon as they are back in stock.

I'm sure Nanofrog will chime in with a more informed response, but the basic advantage to a 10K RPM drive is reduced latency. The faster spinning platters mean that you spend less time waiting for the correct sector/block to be under the read/write head.

However, larger drives with added density like the WD Black equipped with large caches are also very fast... (I'm thinking almost as fast but not sure) but they certainly offer better $/GB ratios.

I don't think you would notice much difference in single drive performance between a Raptor and a WD Black. An SSD on the other hand is another matter :p

BTW, I'm guessing you've ruled out SSD's due to cost?

There's a minuscule advantage in speed, but like ventro said, the drives operate hot and loud. An Intel or OCZ SSD on the other hand, is cool, silent, and will rape the Velociraptor in the butt

The Velociraptor's are nice, but for single drive operation, the advantage is random access. The VR's capable of 7ms or so, while a Caviar Black is 12ms or so. I have both, and those are the figures I've come up with consistently. Random Acces speeds are good for quick loading of OS's and applications. That's what SSD's truly shine at, but as VirtualRain's thinking, I'm also assuming this isn't feasible due to cost constraints.

As your usage is video/graphics work, you need sequential throughput due to the largish data files, so the Caviar Black, or any other large drive with high platter densities would be better. Better yet, get a few of them, 3 or better yet 4, and make a stripe set (RAID0). That will provide the throughput you require for your described usage. Everything would go on it btw, OS, apps, and data. Just make sure you have a drive (or multiples) for backups.

Since the cost of a 300GB VR is ~$230 (before MIR of $30), you can get a pair of Caviar Blacks. As you seem to at least be interested in one of each, you can get 3 Blacks for the same money, and be far better off. :D

That doesn't include any drive for backup of course, but it's still a better way to go IMO. Worst case, use the OEM drive with the system as the initial backup disk. No additional cost to begin with, but be aware that you're going to need more than that soon I would imagine. Either a single large drive, or even a second array, perhaps even attached via an eSATA card and located in a RAID enclosure (it can be done inexpensively, and can contain a considerable amount of storage capacity).

I'm sure Nanofrog will chime in...
:D

I've not had any noise or heat issues with my VR. But there's no mechanical drive that can compete in terms of Random Access performance with an SSD either. Even RAID, though improved, isn't feasible for this either (realistic drive quantity).

But the worst I've ever encountered for noise and heat, are 15k rpm SAS drives (i.e. Seagate Cheetah's or Fujitu's). Whirring oven that can make any case vibrate with a nice BUZZZZZ sound (without vibration dampeners; i.e. O-rings). And push the internal temps noticably (CPU, chipset,...). :eek: :D

Make a partition at the top of the RAID for your OS and apps (I did 128GB total) and you will never want a SSD. Your system will always feel snappy, especially considering a 3 disk RAID using good HDs is as fast as any SSD.

Have SSDs caught up with 10k drives on write speeds yet? Between that and the unknown long-term effects of pagefiles being on them, that's my main concern (after the still-too-high $/GB).

I honestly doubt that, there's no hard drive set up that will ever beat any SSD when it comes to latency and making a partition at the top of the RAID has nothing to do with speed or performance. It'll get fragmented over time regardless of where the data is.

SSD are almost always at .01ms where hard can only be 5ms or faster. RAID does not make latency lower, just improves seq and random performance. In fact, some RAID setup will add more latency to overall performance. SSD in RAID0 is even better. 2x good SSD in RAID0 will not only rape most 4xRAID0 HD, but also exceed some RAID controller's ability to provide bandwith in such that it'll overheat.

It all depends on what the person needs, if he needs super fast seq performance with large amount of storage, than RAID0 of fast large drives. If he wants snappiness and high random performance regardless of space and cost, SSD will always make the list, there's never any HD setup that'll beat a good SSD.

Are you talking about random write or seq write? They both are different beast for different types of SSD. SLC SSDs has beaten both 10K and 15K drives when in both seq and random write. MLC SSD is a different story, seq speed is better than 10K but random still sucks a bit.

Were I you, I'd hold off on the velociraptor for now (I use one for my boot/apps disk). Just get the fastest (lowest seek time) 7200 rpm drive for your boot disk, and use that until SSDs are a bit more competitive. While the VR is a bit nicer, the advantage doesn't justify the cost at this point, when faster disks are soon to be cheaper as well.

I have 4 VelociRaptors in my Mac Pro at the moment. I cannot hear them when they're working and they run very cool. Right now they're running at around 35ºC. My room is pretty quiet, so that's a plus. The computer is very responsive and very fast. I did consider getting 4 SSDs, but I couldn't justify spending $1500 on 4 drives that won't even give me the same capacity.

Thank you very much for the quick replies! I'm not considering a SSD as of now because of the cost but now I am considering doing a RAID 0 with 3 or 4 WD Blacks. Appreciate the help!

How sad, a single SSD will walk all over that for the same cost.

Would a single SSD provide upwards of 1TB of space without breaking the bank?

Short stroking can be quite usefull. :)

I decided to keep it simple, as it could be mitigated anyway (depending on usage pattern), due to simultaneous access of both arrays (the heads can't be in two places at once). :p

What exactly are you doing?
Just read in the OS/application, then access concentrates on the second partition based array for data writes?

Assuming this is the case, it would work out fairly well, but then again, it's essentially the same as a single partition per disk array (not much, if any simultaneous access). Limiting the OS/apps to the outermost tracks do keep it (OS) from being sprawled out, and does help. :D

How about a single SSD in conjunction with a 2TB drive (or three).

2 TB drives are not compellingly cheaper...yet. Also, they're all 5400 rpm as of now, and therefore posess longer seek times.

just one more post to say the drives are noisy as hell, and frankly you are better off getting some denser disk like a 750gb or 1tb drive with a huge cache. Very similar performance and much more capacity .... and less noise!

Yes the inner tracks on the 1.5TB 7200RPM drives are comparable to the VelociRaptor due to the surface density, but when you fill up the drive, the 10,000RPM drive will still be just as fast while the 7200RPM will have slowed down.

People will always complain. Some actually need quiet drives, like in an audio-heavy environment.

Droning, constant noise is fine, because you can tune it out. But HD seek noise pokes out because it is intermittent. As such it becomes really distracting and annoying.

That sort of thing I understand, it's necessary on a technical level.

But HDD noise for the average user? Come on. It's one thing to have a V-Raptor in an external sled with no case on it sitting near your display, that -is- kinda loud (ask me how I know :D ), but internally-mounted drives of any kind (including Cheetahs) in a Mac Pro just aren't that loud… unless you're one of those people who keeps their tower on the desk for some bizarre reason. But those people are already clearly in need of mental health care.

Haha, it was actually just a little thing… I had to make four clones of a project hard drive for work, and realized that there wasn't really a great way to do it other than putting my boot Raptor in an external case, putting the project drive to be cloned in the second optical bay, and then putting the 4 empty drives on the sleds. Knowing it wasn't going to be a permanent setup, I never closed the external enclosure, just ran it open with the drive exposed. I did sort of a :eek: when I powered up the machine, I hadn't heard the drive outside of my machine before that :D

Well, this may be true but I can safely say that I've never ever seen a decent studio where ANY equipment was EVER allowed to interfere with a mic. Positioning and location are always considered - even on live shoots! So unless your computer is making noise on par with a Mac Truck then this is a non-issue if you know what you're doing.

And if they don't know what they're doing then they've no right to complain anyway. :D

So every time I read those comments on-line I always stick my tongue in my cheek and wonder about competence levels. :p

Well, it was just a minor point, but your correct on the competance-part. Low budget from buying that MacMini/cardioid mic? Just record audio in the spare bedroom. :) Ah, projects at home!

Besides, if somebody is worrying about HDD noise, shouldn't they be MORE worried about the noise their computer's fans make?

Depends on the the kind of mic and it's sensitivity profile I guess. But even bedroom recording is again a question of competence. Not in the chosen location but rather in the equipment chosen. If you must be in an environment with fans, street-noise and etc then a good dynamic voice mic is the proper tool. I think that's why the Heil PR-40 (http://www.barryrudolph.com/mix/pdfs/heilpr40.pdf) is so popular. A pro grade dynamic voice mic that specs out like a $2,000 mic sold for like $250.

I do.

My computer is in my bedroom. I use my mac to watch movies as well, I have a large LCD monitor. However, my mac has 4 internal hard drives, 1 external, and two ATI 3870s. It's quite loud, and bothers me when I try to do a regular task everyone is accustomed to; sleep.

My goal is to eliminate as much noise from it as possible now. And the heat from all the internal components). I'm replacing all 4 drives inside my mac pro with one SSD drive (or two, for RAID0) and one HDD @ 1TB. My external is a 3.5" which will be replaced with a 2.5" (good riddance psu cable!). My ATI 3870s will get passive cooling with the Accelero S1 rev.2 heat sink, unless its too big of a heat sink to hold both in slot 1 and slot 2, ill just toss out the second card. The heat it produces is enough to warm up my room during the winter.

Yes, sound is annoying.
