Difficulty deciding between 1 or 2. Unsure about real world performance gain of 2. No experience with SSDs or RAID 0. Worried about alignment and sleep/hibernate issues. Stock 5400rpm 320GB will go inside eSATA enclosure. Does anybody have a good eSATA ExpressCard/34 to recommend? I don't care about the SuperDrive. But I'll keep it for Care warranty purposes.
View 1 RepliesIs it possible to mirror a RAID-0 array to a single drive?
For example, I will be setting up 3x1TB on a RAID-0 (striped) array and i want to mirror it to one 1TB drive. Is that possible or do i have to resort to Time Machine ... ugh
and YES i've already STFA! no answers as of the start of this thread

-edit i assuming Time Machine backs up the "volumes" and not the "drives"
Compatible to PCI-e 2.0
Boot to Mac OS X with Mac Pro (2006-2008) Models
Boot to Single Drive or RAID Array
Well,finaly it's bootable and raid bootable.Does anybody know is ti bootcampable?I just come back from windows,I find I lost so much,I can't even use foobar2000 and my 9800gt.
I hope it will be a positive answer
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?
I am checking out the market on SSDs for my Macbook Pro and I've found a few manufacturers differentiate their product lines as "regular" SSDs and Raid-Ready SSDs. The raid ready's being more expensive and having a little less space. I'm not as tech savvy as I should probably be, so I don't know what Raid or Raid-Ready means and what value it might have.
View 11 Replies View RelatedThe MBP has one expresscard slot. So if you use an eSata adapter (even if it has dual eSATA ports) it would only have one eSATA channel And that would be limited further by the express card slot and more still by the type of card (make, model, etc..). My question is: with Barefeats claiming even the best eSATA card for a MBP being 200MB/s (even if you claim less) using a dual eSATA RAID connection for a stripped array would be limited to 100MB/s per port. Is this correct? Because I'm trying to understand this to see if it's worth building a RAID setup for my MBP when I'm home.
I've asked this numorous times and get helpful advice but not addressng this specific and fundamental fact. I am not interested in FW800 because I want the fastest I can get but want it to make sense. I would also reask my other questions about my situation but this question comes first.
So I'm considering a new boot volume for my Mac Pro revolving around this RAID controller, since I have had great experience with 3ware's products in my Linux boxen and it really seems like $700 for the Mac raid controller is a bit much. My workflow revolves very heavily around virtualization. I've been thinking about a variety of options for SSDs and hybrid drives and even just fast laptop HDs. Am I crazy for considering 2.5" drives other than SSDs? I'm thinking of 2.5" drives because I put a pair of them in the lower optical bay without issue. The amount of storage needed on the boot volume is probably in the range of 150-200GB. Getting SSDs that size may not be in the budget. Thus, I am currently considering either a pair of 320GB WD Scorpio Blacks or a pair of 250GB Seagate Momentus XTs. I'm not sure the hybrid Momentus drives are worth it. Additionally, I know that a lot of SSDs don't fully support RAID in their firmware. Thus, I am reluctant to buy one, let alone a pair, since a lot of places don't seem to have terribly generous return conditions for SSDs. Is this a fool's errand? Should I just relegate my VMs to other storage and get a smaller SSD for the OS + apps?

I have an existing striped raid 0 setup with 2 x 500 GB hard drives.
I just bought 2 more x 500 GB hard drives since i noticed HDD is a bottleneck for my 8 core system.
my question is, can i add the 2 harddrives to my existing raid 0 partition ? (so i have one raid partition of 2 TB )
I have a Early 2008 Mac Pro. I have the Apple Hardware Raid Card Installed. I have 4 2TB disks installed. Currently I've got the system disk setup in Bay 1 as a single disk. Then I have the disks in bays 2 through 4 setup as a raid 5. I've been thinking that I might be better off to make all 4 disks into a raid 5 array and then just make volumes for the system disk and my work disk. My goal is to have a system volume an a scratch/work volume for image and video editing.

I am fairly certain how to go about and build myself a basic file server for a bunch of PCs networked together, but I am not sure about how to do it for a network of Macs.
View 1 Replies View RelatedI have two choices.
1. Apple's Mac Pro RAID Controller, Four Drives, RAID 0+1. One big disk, highest cost.
2. Or, some other RAID Controller (?), Three matching drives, RAID 5. Then, 1 big drive for OS/Applications/Time Machine.
I'd probably move my Home folder to the RAID Array and have just my data striping amongst those drives. Has anyone had a dilemma like this before? I like the idea of hardware separation of my Home folder from the OS.

View 2 Replies View RelatedI'm still working out the details on purchasing a new MacPro. My Apple sales rep tells me that I can greatly increase the launch speed of applications and the system OS by purchasing 2 hard drives and using Disk Utility to stripe them together into a "software RAID". They claim it will be faster and more reliable than a single SSD. I know I've asked this question before, but the answers were over my head. I don't know anything about SATA raid cards, or SSD's except for their benefits. But I'm pretty sure I can stripe two drives together and make a software RAID.
View 24 Replies View RelatedI have a quick noob query about SSDs vs. HDs in the MBP
Pretty much, what are the advantages of having a solid-state drive over a normal 5400 or 7200 rpm drive? Is it just speed vs. space?
I mentioned to someone that I was thinking of buying the optional 128 or 256SSD on the MBP I intend to buy, and perhaps in a couple of years buying an SSD of greater capacity. (The 512 is beyond my budget at present.)
The person I spoke to didn't think this was a good idea because the 128 and even the 256 would soon fill up with photos, and that I would then want a larger drive.
(Backing up an external drive is of course highly recommended, but it's pretty neat to have all one's photo collection on the computer's own drive.)
Replacing an SSD with another, he said, was a "dickens of a job" as the existing (factory) SSD is built into the mother board.
Just found this when I was browsing through some stuff.That's the controller that can be found from Toshiba HG2 SSDs that are used in at least 2010 MBPs. Here's a pic of the MBA's SSD:Original pic by iFixit (full size)As you can see, both are using Toshiba's T6UG1XBG Solid State Drive controller
View 2 Replies View RelatedI've been surfing the web for hours now to find the right SSD for me. I have an ExpressCard SSD which unfortunately is having too many problems so I am planning on buying the MCE OptiBay to replace the SuperDrive with a second hard drive.
So my intention is to buy a cheap/small SSD to install OS X on it and to keep the home folder on the internal drive. There seem to be two SSDs which fit into that category. I need some advice whether those two products even work on my MacBook Pro Early 2008 2,4GHz, or if there are any other incompatibilities & problems.So the two candidates are Intel X25-V 40GB or OCZ Vertex 30GB.
The OCZ offers less space and costs slightly more but neither of them are really significant as they are in my price range. The OCZ ("Read: Up to 230 MB/s & Write: Up to 135 MB/s") seems to be much faster then the Intel one ("Read: up to 170MB/s & Write: up to 35MB/s"). Especially the writing speed of the Intel X25-V is really poor, even when compared to normal HDDs.
Recently I revamped my computer. I bought an Areca 1680 with 2GB of cache and 3 120GB Vertex 2 SSDs.
I have the 3 SSDs striped in RAID 0 on the RAID card and my old 4x 300GB VRs in RAID 5 on the same RAID card. The old drives in RAID 5 on the new card seems faster, probably due to the extra cache, but the SSDs are weirdly slow.
With Quickbench, I can't seem to push past 500MB/s for reads and 450MB/s for writes.
I'm pretty sure 2 drives can push those numbers. I know it's not a south bridge issue and the RAID card is in the second PCIe slot.
Could it be my stripe size? Right now I have it set at 64KB. Write back cache is enabled and TCQ is disabled.
(For reference my RAID 5 gets 205MB/s read and 370MB/s write for a 4GB file)
I want to install two X25-M SSD's in my second optical bay. I have already modified an old, empty drive case to mount both SSDs so I just need to know what cables I would need.

View 2 Replies View RelatedI 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.
