Is There A Max Drive Capacity Limit For Mac Pro
on May 7, 2013 at 10:10:49 am

Can I put 2TB, 3TB or 4TB drives into my 2010 Mac Pro and Raid them or are they too big (for the OS? Hardware?) or is it ok? All the same of course.

Considering either of these:

There is a speed limit on the bus. If your goal is speed, a 4 drive RAID connected via SAS to an ATTO R680 card will be faster than the 4 internal drives RAIDed together. the internal SATA connections are 3G whereas modern drives are now 6G. Software RAIDs (using the internal bays) have a bit of processor overhead too.

if you're going to RAID, make sure you use drives designed for that. don't use "green" drives or those that spin down.

you can put drives in the optical bays too, for 6 drives internally.

if you're only going to use all these drives occasionally, i would recommend an external box that you can shut off. I have all the bays in my Mac Pro filled and it's amazing how much power this thing sucks at idle. Surfing the internet uses like 300 watts, whereas my MacBook Pro is like 20w. just another thing to keep in mind.

Hey Eric thank you so much for your reply. I was remiss in not describing my rig - it's a 2010 MacPro 12 core with an Apple Raid Card and 1tb drives in each of the 4 bays. Bay 1 is the system drive, bays 2-4 are a Raid 0. So the bigger drives would replace bays 2-4 for more capacity. I am reasonably satisfied with the 250mbs throughput I get for my DVCPRO HD material. It's just that 3tb is getting to be too cramped nowadaze. I would use WD Caviar Black or similar 7200rpm drive. I was concerned over whether the jump from 3 to 6gb/s and 32 to 64mb cache would be tolerated.

Western Digital has changed their line up a bit. they no longer recommend the Black (or what they're now calling the Black) for RAIDs. their new desktop RAID hard drive is the Red. they also have an enterprise version called the RE. but my go-to is Hitachi Ultrastar.

you'll also get a massive performance increase if you switch your boot drive to an SSD.

I don't see "Ultrastar" on WD's site. is the RE the same?

all i see are HGST, subtitle "a Western Digital company". are they sticking with the HGST name or switching to WD eventually? kinda confusing.

Kinda pricey then http://www.newegg.com/Product/Product.aspx?Item=N82E16822145621

I don't see an RPM for the WD Red Drives...got burned by Green, now suspicious.

I back up with an OCD passion so I think the less expensive drives might still be ok for me.

Back in the Media 100 daze I used to have 10K rpm SCSI drives...ironic ain't it?

the Reds will be 7200.

use cheap hard drives for archive, not for RAIDs

Eric - here's what bothers me about the Red drives - IntelliPower had a Green ring to it, eh? (headers would not line up)
Model # Interface Form Factor RPM Capacity Cache
WD30EFRX SATA 6 Gb/s 3.5 Inch IntelliPower 3 TB 64 MB
WD20EFRX SATA 6 Gb/s 3.5 Inch IntelliPower 2 TB 64 MB
WD10EFRX SATA 6 Gb/s 3.5 Inch IntelliPower 1 TB 64 MB

wow, i apologize for being so wrong about the Reds. i guess i shouldn't trust what i read on a company's website.

i wonder why WD would tout an Intellipower 5400 RPM drive as their RAID drive?

still recommending the Ultrastars. been using them for years in 24/7 RAIDs with no issues. they're expensive because they're the best. 5 year warranty. HGST has a no questions asked return/replacement policy.

I'll add that the Hitachi also have a higher MTBF, there rated at 2 Million hours vs the WD RE which is 1.4 Million hours. I've worked with both drives on a daily basis and either one would do great in a RAID environment.

Ricardo

i'm surprised to see the writes so much faster than the reads in your tests. is that the case, or are the number flipped?

thanks

Nope, they are correct. We start seeing faster read performance with more drives.

For example, the same test using 8x Hitachi Ultrastar drives in RAID 5 show the following.

Read - 710MB/s
Write - 855MB/s

The WD Red drives are 5400RPM drives. Here's some benchmarks comparing both the WD RE and WD Red drives we just conducted last week.

4x Drives RAID 5 - Using Macbook PRO connected to the Areca ARC-8050 Thunderbolt Unit.

WD RE (WD4001FYYG)
Read - 375MB/s
Write - 530MB/s

WD Red (WD30EFRX)
Read - 211MB/s
Write - 489MB/s

No surprise, the 7200RPM WD RE drives are much faster.

And, if your wondering how the WD RE compares with the Hitachi Ultrastar, here's the benchmark numbers we got.

Hitachi Ultrastar
Read - 342MB/s
Write - 525MB/s

The performance of the WD RE and Hitachi Ultrastar are very similar, Again no surprise since they do share the same overall design and both use the 5x 800GB platters. It comes down to user preference, mine is the WD RE.

Eric,

You are correct.

HGST (formerly Hitachi Global Storage Technologies) is a wholly owned subsidiary of Western Digital that sells hard disk drives, solid-state drives, and external ...

http://www.hgst.com To me it kind of looks like it's HGST by WD, which IS confusing.

Thanks for correcting me, you'll see Ultrastar drives there.

[peter tours] " I was concerned over whether the jump from 3 to 6gb/s and 32 to 64mb cache would be tolerated."

Far as I know, 3G vs. 6G is a non-issue as either bus is much faster than the drive's media transfer rate. Fast spinning drives like WD RE and Ultrastars transfer at about 160MB/s while SATA 3G tops out at about 300MB/s. Upping the bus speed to 6G does very little to improve performance - unless you're dealing with external drives (port multiplier eSATA) or SSDs.

Just my two cents.

I would keep the system drive and replace the three others with 3x4TB Hitachi Ultrastars (now WD). You system will provide enough power to handle DVCProHd or any other HD material except 4K.

Cheers

??And this suggestion would then use SoftRaid or Apples Software Raid,.. since the Apple Raid Controller can NOT handle >2.2TB. Best is 4x2TB

Not software RAID, you were right that it's the Apple Raid card. 2tb limit is what I suspected. What about 3mbs vs 6 mbs.

According to Blackmagic drive speed app, my write speed is around 240mbs and my read speed is slightly higher - would this improve with a software raid? Otherwise I still see no benefit from removing it.

Thanks!
