What to expect from iMac 2012 - Discussion

[jsolares]

Rocks.
Please its very important to me,if you wanna just joke,joke,
but really are only my worries,can you share a little knowledge with me?
Thanks.

He's right, even data on Hard drives can become corrupt via bit rot.

You would need to use a filesystem that's designed to prevent it, like ZFS but there's no easy plug and play solution for the time being. maybe when zevo platinum comes out, that ones supports multiple drives so you can recover from bit rot and not just find out about it.

I have never used it so I don't know what it's like. I am being forced to buy an iMac for the first time so I can use xcode. I wont elaborate any further but I have no choice in the matter.

Anyhow it's not long now before they are released ...

Never used what? OS X? xcode?

In that case,

Language *timeToLearn = [[ObjectiveC alloc] init];
[windows release];

Best computer, best OS, best programming IDE. Enjoy.

Not really. Most people didnt need this, but again - if you are recording a video stream, which approaches throughput of the drive, and theres no buffering - then it helped. Google should find references to these devices. As device capacities increased, and the controllers had their own (few) megabyte caches, the distinction all but disappeared. Nowadays, I think most drives have at least a few megabytes of cache (which causes a lot of complexity for high-availability data center quality devices).

Problems today, arise when the drive has ACKed the write to the drive but the data hasnt made it to the platter. Cheap drives can lead to corruption in the event of powerfail since the OS "believes" the drive to have committed the data. High end NAS type kit uses battery backed SD or RAM to ensure even in the event of a power fail, committed data is "truly committed".

The use of SD as a large cache for the drives today, is predicated on what happens during powerfail. Many of us "dont care", but those living in areas where black/brownouts happen frequently, either need a proper power backup solution, or hope they werent writing metadata to the disk when it failed. (Many OS's, including Linux/Mac/Windows, use journalling file systems to avoid the bad-old days of fsck).

Apologies, am going off topic. Just waiting for my raspberry pi to boot...whilst waiting to decide what imac to order...

 

[Apple fanboy]

What are you using your raspberry pi for?

 

[lifeguard90]

Can we get back to talking about the imac

Oddly enough I do remember something about calibration from those days and the old hard drives did indeed need to calibrate to find track 0.

When there's something new to talk about sure.

We can't make it come any faster anyway.

Oh, oh! I know, I know!

Will it come with SSD+HDD, SSD being standard boot disk? If not - will adding a SSD be cheaper this year (from apple)?

Will the RAM be bumped up to 1600 from 1333?

Good questions. I really really hope the cost of a SSD comes down. I'm hoping for a 512gb SSD option.

Both! we shall see old boy we shall see

A-ha! Never used OS X before....now it all makes sense. Do yourself a favor and go through some of the Mac 101 tutorials and get acquainted with the OS before you get the machine. For me, some things in Windows are better than in OS X and vice versa - but overall the OS X experience is much better. I'm willing to bet that you'll like it.

I'm suspecting SSD+HDD standard at top 27", SSD BTO otherwise and cheaper + better quality.

Hard to speculate on the RAM speed.. if I had to guess, I'd say no.

Already been through all the tutorials! I'm eager to get started as soon as Apple release the hardware

Relative to the topic before it: Yes!

 

[boy-better-know]

How much of a delay do we think configuring will cause at launch? I am hoping they are all promised to be delivered before Friday.

 

[Paradigm]

the end of the Euro in the current form ?
the end of the Iranian regime ?
a new US president ?

who knows ....

I AGREE!!! Thank you

I am fairly sure that standard RAM will be 1600 MHz. The leaked geekbench results also support this. I am already running 1600 MHz RAM in my 2011 Mac.

Guys, did you thought that maybe the 27" isn't 27 but 30? That can explain the price bump we see on the " 27" " model.

 

[HurryKayne]

I have the strange sensation that only analogic can save our files,
vynil for audio and real photo album with our printed and plastified photos..

 

[Mr Rogers]

God I'd love that

Forget RETINA and SSD - a 30in or 32in iMac would be fantastic, hence I hope you are right - I have US$2,200 burning a hole in my pocket and would willing pay a little more for more screen display - particularly with new motion devices becoming available at years end - my kid will be blown away by games that you can control with hand gestures alone!

Would be a theory - but seeing as Apple are pushing the retina (probably next year for iMacs) it'd be plain stupid for them to move on to bigger screens as it'd be an even huger and more expensive challenge.

Also, on a sidenote - the TV when I was growing up was 28", going up to a 30" screen for a desktop seems like crazytalk to me! (I already think the 27" is a bit crazy for private normal-computer-usage)

What price difference? The prices in the rumours are in Australian dollars and for the Australian store. Have you seen the current prices on store.apple.com/au ?

There's a slight price raise.

"Video Hard Drives" generally referred to HDDs with firmware tweaked to improve the reliability of sequential writes to the platter. Everything, from reduced recalibration frequency/duration to exotic zone strategies, was used depending on the company/generation.

I believe that these are a thing of the past, since HDD technology has advanced in ways that have mitigated (or entirely removed) the need for these specialized drives.

That said, Video grade HDDs were pretty rare in the consumer marketplace. HDDs now can still be found in enterprise, OEM, and retail flavors. As with Video grade HDDs of ole, the difference is typically firmware and a different sticker.

 

[Razeus]

For the love of God, USB 3.0 please. Thunderbolt is DOA.

Cheaper SSD options would be great as well.
