Mac Pro :: Raid 6 Versus 60?

Oct 8, 2010

Okay, so... To make a raid 60, you make a raid 6 first then stripe that. If you started with a 4 disk raid 6 array and increased your number of disks to 8 when you stripe it, I have no trouble visualizing performance and capacity advantages.

However, I'm having trouble visualizing trade offs, speed or capacity differnces if you compared a 8 drive raid 6 vs an 8 drive raid 60.

If you are not Nanofrog, but you did stay at a holiday inn last night, you are welcome to reply as well.

Mac Pro :: Software RAID Versus Hardware RAID?

Apr 20, 2010

I am planning on getting a 2010 MP when they come and have a question about it. I am 90% sure that with my budget, I will not be able to after a RAID card. I am wondering if software RAID would be alright or if it's so bad it's not worth doing. Also, there is small chance that I could buy a RAID card later on, how would I install it? I will be using it for 3D animation with Maya and some zbrush modeling. Also I will be doing some Photoshop and illustrator and maybe some gaming on win 7 boot camp. Feel free to list any other pros and cons about either a software RAID or hardware RAID, I wana make sure I have all the details before making a final decision on it.

Mac Pro :: Time Machine Versus Mirrored Raid

Apr 7, 2009

Having spent that much on a computer, added to the fact that I'm now starting to get more music/audio freelance work, means I'm keen to get a decent backup system going. I aim eventually to get a 1tb external drive and use time machine to backup my samples drive, but what do you reckon would be the best option for the system drive?

Hardware :: Can A RAID 1 Guardian Maximus Rebuild Easily / Have Partitioned The RAID Set

Dec 2, 2009

I just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)

My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.

Hardware :: Dell 2407WFP A04 Versus Dell G2410 Versus Dell 2209WA Versus Samsung F2380

Nov 2, 2009

I'm looking for a new monitor to go with my MBP, and I'm stuck trying to choose between the ones listed above.

The 2407WFP is a couple of years old now I guess, but it's the rev A04 version, which supposedly fixed the (few) problems with what was otherwise meant to be a great screen. It's an sPVA screen.

I've heard good reviews of the G2410, with its LED backlighting. It's still a TN panel and I hear so much bad stuff about them.

The 2209WA is an eIPS panel which I like the sound of, but it's smaller and lower resolution.

The F2380 is a cPVA panel, the image quality looks better but I've heard bad things about blacks on this panel.

Mac Pro :: Get A Highpoint Raid Controller And Put Those 4 Drives In A Raid 5 Array?

May 1, 2008

I have a macpro with 4 x 1tb drives

Is it possible to get a highpoint raid controller and put those 4 drives in a raid 5 array (and then create partitions inside that array) - or do you need to have 1 drive by itself for the operating system, and then create a raid array using the remaining 3 drives?

Lastly, are the highpoint 3500 series a decent card? and fully compatible?

Mac Pro :: RAID 5 Volumes - Create In RAID And Disk Utility?

May 20, 2009

I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.

Mac Pro :: Raid Speed ... Raid 5 Vs Straight Sata HDs

Jan 28, 2008

ive put 4 of the hitachi 1tbs in my new mac pro.. and i really want to do Raid on them eventually.. and buy the pricey apple raid card.. i'll do it.. but speed wise:

How fast is a Sata connection straight from HD>Motherboard... ~75mb/s?
Is the Raid 5 config with all those drives much faster... around ~110mb/s?

Do you know if there is anyway to get a 5th drive into the raid 5 array? using the ODD space.. or some externals too... i need as much as space as possible...

And boot camp wont work with raid card anymore? I was thinking to have the startup disc be a raptor to increase speed on the apps, how would it integrate with the raid card, etc

I'm pretty satisfied with the Marware cover, although it can be a little frustrating when typing quickly..I'm wondering if I should go back, return the Marware cover and pick up the iSkin.

So, for those of you that have any of these in comparing..which do you think is the best?

And yes, I did search and am aware threads like this exist..but I couldn't find any comparing all three, only iSkin vs. Moshi.

Hardware :: Eyetv 250 Versus TVMax Versus Blackmagic Video Recorder?

Apr 30, 2008

I'm trying to decide which product to buy and I was hoping for some advice.

First and foremost I want a device so that I may transfer my VHS tapes to DVD.

Live TV recording is secondary but for the price, I'd like to find the device that suits me best so I can continue to use it after i've transferred all my VHS.

Here are my concerns:

1) I'm going to be moving from the US to Ireland in a couple of months (not sure for how long, could be years+) Obviously there's the whole NTSC vs. PAL, ATSC vs. DVB.

I know with EyeTV 250 it's either or, any ideas if buying some sort of converter is an option (prices, quality)? If I bought just a PAL one, would I still be able to convert VHS or would it be completely unusable in the US?

2) I'd like some sort of HD/Digital abilities. From what I can tell TVMax is analog only and Blackmagic may also be but I can't find more specs on that.

Does this mean they'll be useless once the US undergoes the conversion?

So as of now I'm leaning towards EyeTV 250 but the question are there any forseeable problems with using a PAL to NTSC converter or using a PAL EyeTV in the US just to convert VHS.

Mac Pro :: Setting Up RAID 1 Without RAID Card?

May 15, 2009

I have never setup RAID before and this question may be totally stupid for that matter.

Can I setup RAID 1 (or call it mirroring) without the RAID card? I have two 1TB internal drives in my Mac Pro and I want to mirror them. I don't want to spend another 700 bucks just to setup a mirror.

Disk Utility shows some RAID options, but I am not sure how to use them, or if they will work at all without the RAID card.

Mac Pro :: Mirror RAID Or A Stripe RAID?

Feb 14, 2010

On my 2009 Mac Pro, OS X's disk utility seems to allow the provision of making a mirror RAID or a stripe RAID.

Is it possible to shove in 2 drives, make a RAID 0 for two of them, and then add in 2 more drives to make a RAID 1 out of that RAID 0? (a RAID 0+1?)

PowerPC :: Older G5 Versus IMac Versus MacBook Pro For Work

Oct 25, 2007

So I have a 1.8ghz dual G5 with 3gb of ram for work. I mainly work in Adobe CS and do a far amount of Photoshop work. At any given time I may have all of Adobe CS plus Office and a few other apps running -- and a gazillion fonts. Went to the store and saw the new 24" iMac. How would a new iMac compare to my late '04 1.8DP G5? On that same note, how would a new MacBook Pro compare to the above?

Hardware :: Dell G2410 Versus Samsung F2380 Versus Other...

Oct 25, 2009

I am planning on purchasing a new display for use (currently) with my imac. I am completely torn between these two models, and cannot make a decision. Any thoughts? I like the Dell because it is LED backlit, thus good blacks and little to no backlight bleed. But I like the Samsung because of the (supposedly better panel and (supposedly) better color reproduction. I like the simplistic look of both of them (though they could look a little better ) so I'm not sure which one to buy.

Mac Pro :: 6GB Versus 8GB Triple Versus Dual Channels/PS4 Tests

Jun 30, 2009

I ran some tests on my 2009 Quad Nehalem to try and determine what was up with the triple Vs dual memory "brouhaha".

I posted the results as a new thread because I think it will be useful information for a lot of quad owners, but it was originally going to be a reply to this thread: http://forums.macrumors.com/showthread.php?t=735845

Here we go. Tesselator suggested 3 tests that could show the differences in speed between triple and dual channel bandwidth.

Quote:

As one idea I would maybe try creating a few very large images (16-bit, blank white, blank black, gradient fill) and then duplicating and deleting that layer repeatedly a few hundred times.

So I did them, 10 times each. I could have gone on, but the results were very very stable after the first 2 attempts.

Set-up: a 40Mpx, 16bit image (8000*5000). First test it was simply filled white; second test: black; and third test a black to white gradient. I added a fourth test, using a real (photo) 12Mpx RAW image from my Nikon D300.

I created (took a while!) an action with 350 repetitions of "duplicate layer" and "delete layer", followed by a red fill to let me know the action was done. The same action was used in all four tests.

The computer was restarted before each of the four tests, which may explain the irregularities on the first 1-2 attempts. Nothing else but PS4 was launched.

The results are interesting:

We can clearly see that the simple white and black fills show a speed difference of around 10%.

We can also clearly see that this difference disappears when a more complex image is used. The use of more complex images represents a much more realistical use of PS.

To make things even more realistic, I also tested RetouchActions's speed test on my own 12Mpx image. I use nearly all of the operations of that action on a daily basis, so it's a lot more representative of the work I do on PS.

Here are the results:

The results are clear: 11% increase in performance using 8GB of ram (Vs 6GB) when working on a 12Mpx image.

Added info: number of page-outs after running the 10 test series (after about 45 minutes of intense PS work):
-17K when using 6GB (1.7K page-out avg).
-10K when using 8GB (1K page-out avg).

For me the results are definitive: unless I plan on working only with full black or full white images (not even black and white!), having 8GB is better, even when working on smallish 12Mpx files. I imagine the differences would have been even greater using bigger file sizes of actual complex images.

What would now be interesting: someone with a 2009MP Octo doing the same tests at 12GB and 16GB.

IMac :: 24 2.66 Versus 2.93 / Gt130 Versus 4850

Aug 17, 2009

Two short questions on which I really need an answer. This academic year, I'll be writing a lot of papers, but most specifically, I am forced to use SPSS (statistical software package for social sciences).

Will I really need the 2.93 over the 2.66 and notice the improvement?

Same goes for the gfx. I like full-hd 1080, I'll be in InDesign, and use Logic Pro. Will I need "slash" notice the 4850 over the gt130?

Also, are the "hang-ups" with the 4850 truly fixed and does it indeed run a lot hotter (inc. really that more noise) than the gt130?

Applications :: Office:Mac Versus Office - Windows And Camino Versus Firefox

Feb 14, 2009

I've heard Office:Mac isn't that great, and doesn't make up for what iWork 09 is missing. So I'm wondering what people think about it and why does it get such a bland reputation? Also, do people use a combination of the above? Such as iWork and Office:Windows? Both Offices? I do mainly word processing, some soft Excel work (no hardcore giant spreadsheets...yet), and general PowerPoints for presentations. I have access to cheap iWork/Offices (school discount) and a family pack of the top-level edition of Office:PC (family) so it isn't a big deal to get any of the above.

Lastly, what's the difference between Camino and Firefox? I use Firefox currently and love it, mainly due to the add-ons (weather at the bottom, Gmail alert, skins, page views, other customizations). Tabs seem to be on all browsers these days, so are there any other key differences?

MacBook Pro :: Sleeve Versus Case Versus No Case Or Sleeve

Jun 25, 2010

Soon i will be getting a Mac(i think) and was wondering about a case. Since i want a Macbook Pro with the Unibody Housing i want it to be safe. Now i can't decide if i want a case or a Sleeve. Now the Case might have heat issues even with the vents that are on the case. The sleeve won't have that issue but will it be more prone to scratching the Macbook it self? Or should i go no case and just sorta deal with the scratches. There is a Price difference between the Sleeve and the Case. About $20 Cdn more for the Case.

Mac Pro :: How To Know About RAID?

Aug 5, 2008

Currently I have a stock 320G drive installed with a 750G F1 Spinpoint installed as a Time Machine. I have maxed the 320 out so I'm looking to get a bigger drive.

Question: looking at the F1 Spinpoints, should I do 1x750 with 32M cache? Or 2x400G in a software RAID0? The 400s have a 16 Meg cache, so 32M total.

What's better? Do you think I'll see a better performance boost by striping over 2 drives with 16M cache each, or sticking with 1 drive with a 32M cache? And with the 2x400, I'll gain about 50 Gigs of storage over the 750G drive.

2x400 is $156
1x750 is $125

Is this a decent boost for only an additional $25, or should I just save a drive bay and get 1 drive?

Power Mac G5 :: Add A Second HDD As A RAID?

Oct 19, 2007

My Mac is beginning to run low on free HDD space. I'd like to add a second internal HDD to boost space. However, I don't like having a completely separate HDD icons because I can never remember which files are on which disk, not to mention a lot of copying between the two.

I'm considering adding a second HDD and combining the two into a RAID setup. Do I have to reformat my existing disk, or can I just add the second HDD's storage onto my existing disk with Disk Utility?

If I can just pop in a second HDD and add its capacity to the existing one's, that'd be ideal. Having to clear off the existing disk before joining the two would be a chore, though.

Ive heard conflicing statments that the raid is software/hardware. anyone know for sure what it is (Im not talking about that card you can buy).

If it is software raid does this take a toll on the processors? is it serious or does it not matter at all.

IF it does matter. should I buy a exteran raid card? is there a mac compatible one. I just need basic raid0.

I just bought 2 samsung spinpoint F1 750s in anticipation of my new mac. But just want to make sure that raid is a wise decision.

for those who are thinking about replying about the dangers of raid. I know. I have time machine. if the raid goes down then so be it. such is life. I will have backups.
