I just need a bit of help deciding between a software RAID5 vs software RAID1 array for archival purposes. the RAID will be installed into my hackintosh and shared over the network for TimeMachine backups as well as extra backups from my multitudes of external HDDs. i am thinking 3x1TB WD Greens (RAID5) for $103Aus each, or 2x1TB WD Greens (RAID1). my main concern is data loss and speed of the drives. most setups will clearly equal 2TB of total data storage, we feel that will be enough for a few years (will be backing up 2x laptops + 2x iMacs + the hackintosh). which one will be faster? (i guess this wont matter as the network will be the bottlebeck) which one will be more secure in the end? (our house tends to have power dropouts). the network is a gigabit network over cat5e, we may upgrade to cat6e in the future if the speed benefits are THAT great. i am forced to go with a software RAID via OSX at this point in time because a RAID card is just too costly. my current motherboard in the hackintosh is a GA-EG31M-S2 Gigabyte. it has 4 SATA ports and no RAID support - will OSX still be able to do a software RAID? i am presuming that it can. anyway, what are the main pros and cons for this sort of setup?
I'm about to pull the trigger on a RAID5 card for my MacPro (4x750GB) and I want an external (different building) RAID5 for network backups. I'm not quite in the market for a full >4TB RAID system as the price points still seem quite high. I was thinking of this system:

Any thoughts? Would 4TB RAID5 be a good Time Machine back-up for my 3TB RAID5 MacPro in terms of space?
Can anyone recommend a better system? We can afford to spend more, but I'm hesitant to pull the trigger on a ~$15k 16-drive RAID system. Part of my was thinking (hoping!) the Netgear system may support 2TB drives if they become available and that system would continue to support our needs for many years.
I recently bought the Areca 1880ix-16 card and the backplane cable to hook to the mac pro internal drives - hooked up 4 x seagate ST32000644NS 2TB enterprise drives for an internal RAID5 with 6TB of space. Used the DX4 from transinternational to hook up my 2 SSD drives. The initial raid build time was just about 2 days (!) for the raid 5. Shortly after that I left town for a few days and came back to an alarm in my computer - one of the disks had dropped out. The rebuild time was again close to 2 days!. At thipoint I realized that if I was sitting there with that much data at risk for a 2 day rebuild, it would be agonizing and so I needed to go raid6 (which had been my goal from the start, but only 4 internal disks is very limiting). So I gave up on managing my storage internally and bought an istorage pro it8SAS external box connected by miniSAS cable. The raid5 had to complete the rebuild before it would let me expand to raid6. I added another seagate ST32000644NS 2TB enterprise drive (interestingly the drive that was originally listed as failed has caused no further problems at all) and expanded the raid to RAID6 with the same capacity but one extra drive for parity. The rebuild now has been going on for almost 48 hours and it's at 53% I had NO idea the rebuild times would be this long. I do have 2.3TB of data on the array, so I'm not sure if that prolongs it vs. an empty array. But just for others info, take into consideration these times when deciding what your own needs are - I bought a high end (AFAIK) raid card, running in a high end computer (mac pro 3ghz octocore with 16GB RAM) and quality enterprise drives, and it's still maddeningly slow to rebuild. Hopefully once it's up and running, this will all be forgotten, and if I ever have a drive fail, I know I can still lose another one without any data loss. RAID6 seems the only way to go given these times for rebuild. FWIW, I also put in another 3 drives - old 500gb drives I had sitting around and built a secondary RAID5 array since I had the space, that completed in around 36 hours or so, and was done during the original raid5 rebuild.
My server that i currently have is seems to be on its last leg (4 years old with old slow hdd). Anyway, I'd like to replace it but would rather just use my mac pro. I need about 4TB of storage space. Ideally I'd have one hdd to kick in if another began to fail. From my readings it sounds like I need Raid5 (correct me if I'm wrong). I know this can be done but I've already used 3 drive bays that came with my mac pro, anyway I can setup a raid 5 and have the storage space? I guess what I'm looking for here is some type of RAID card (Arcea 1210?) and then a storage solution. Once thats figured out, I'll need to know how to power the hdds.
Wondering whether I should purchase a Macbook Air or Pro for college. I'm a Freshman and a inteded Political Science major with a minor in Secondary Education. I'm having a hard time picking
I am trying to run Darwine 0.9.27 on my Mac (OSX 10.5.6) for emulation purposes, however it does not work. I downloaded X11 2.3.2.1 from the Xquartz project to make sure I was up to date with X11, however that did not solve the problem. For example, here is the error I get when I try and run Knytt, a compact, free Windows game: err:module:attach_process_dlls "gdi32.dll" failed to initialize, aborting err:module:LdrInitializeThunk Main exe initialization for L"Z:\Users\Banjaloupe\Games\Knytt\Knytt.exe" failed, status c0000005
I think the problem is with X11, since I also cannot run GIMPshop, which I know needs X11. However, I have no experience at all using X11 in the first place, which is why I am quite stumped. Of course, the real issue could be with Darwine, or some other incompatibility I'm missing.
I am in the market for a new monitor, I would look at matte IPS monitor, but so far (and I haven't done that much research so far) I have only really found the Dell 2209wa which looks great but its only 1680x1050 and I would much prefer 1920x1200 or something to that extent. Those are really my only requirements matte and 1920+ but I also don't want to go above 24" because then it just starts getting too big (especially since it will be in a dorm room next year).
I have recently bought a MBP so am new to OSX.I dont have a backup version of OSX on CD or DVD. Is there a way of downlaoding a copy from the app store that I can archive in case I need to reload the MBP?

I am having a hard time deciding on which laptop I should buy. I narrowed my search down to:
-HP's HDX18, -MacBook Pro, t -Dell XPS 16, -Sony Vaio AW (with the 18 inch screen).
I watch movies in abundance. My film and music libraries are about 500GB. I also enjoy taking and editing movies and pictures. Weight is not an issue. I would be very thankful if you can help me choose which of these LTs is the most enjoyable. I'm going to Grad School in France next September. My laptop should be my main source of entertainment.
My mother is switching to mac soon, mostly likely an iMac to use as a family computer for her and my youger sister. She likes what sees so far especially in parental controls. However, she wants to be able to keep tabs on my younger sister to make she isn't going to places or saying things she shouldn't be on the web; she wants a second layer of security (she worries that she can get around things parental controls because she is very computer savvy). I figured a keylogger would be the best thing because we could keep track of everything she types on the mac. Does anyone know any good (free) keyloggers for mac?
What is a good software for making demos? Mainly I'm looking for something that i can use to record screens of my mac pro and create a quicktime move out of it so that i can use it for training purposes. I read about SnapzPro but was wondering if there is anything else available.
I am curious to know if L2/L3 cache impacts the performance of a macbook being used for Design and Drafting purposes. Of course this involves retrieving and real-time changes that will be made on a server and/or the macbook itself. Secondly, how significant will the functioning depend between a 3mb and a 4mb L2/L3 cache?
After a bit of Google research I've found countless notebook elevators for cooling purposes. So many to choose from. Just curious if any MacRumors users could share their first hand experience?
I have a 13" MBP and am looking for a slight elevator to let air get under the notebook. I do not want a stand with actual fans / coolers that plug into your notebook and use battery. I'm just looking for a simple, glorified phonebook to stick under the MBP
I'm going into high school and I have been doing my research in finding a laptop for me and high school. I have been torn between the MacBook pro 13 inch 2.5 ghz and the MacBook air 13 inch 128 gb. I don't know what one to choose and I know that the air doesn't have a SuperDrive but you can get one on amazon for $25. I'm not going to be doing anything 3d or designing stuff. I'm prob going to get word PowerPoint and excel puton there and that's about it. I'm going to use the Internet a lot too! Let me know what I should do
while trying to make a presentation or simply playing a video from my MacBookAir over thunderbolt/HDMI table to large screen I am experiencing problems with audio only being played from the MBA and not the soundsystem built in to that screen (unless using a VLS application and manually selecting the audio output target).
how to steer audio output device using 2in1 cable such as thunderbolt?
