(Or, if you’re in the rest of the world, iDataCentre)

According to Data Center Knowledge, Apple are hiring for Chief Operating Engineer, Site Coordinator, Site Services Manager, Electrical Technician, Maintenance Technician and Operations Shift Supervisor for their data centre in Maiden, North Carolina.

Apple planning US$1 Billion iDataCenter

According to DataCenterKnowledge apparently Apple is planning on spending some of its billion dollar cash on hand to build a US$1 billion data center on the East Coast, either in North Carolina or Virginia (as they battle to legislate the best incentive packages).

Western Digital 500Gb 2.5inch Scorpio Blue’s are hot!

I bought a 500Gb 2.5 inch Western Digital Scorpio Blue with the intent on sticking it in my MacBook Pro. To give it a a bit of a test run first I put it into a “G2 Mini Combo – USB 2.0/FireWire 400/800” external case from Zytech.

Formatted it with lots of Zeroes, copied the MBP’s contents onto it. And noticed that by this stage it was literally too hot to touch.

Checking out the data sheets shows that it’s maximum operating temperature is 60 degrees C. It requires 2.5W for read/write, 0.85W at idle, 0.25W at Standby and 0.1W in sleep. I’m guessing that the drive currently inside the MBP is a Fujitsu MHY2200bh drive with 1.9W read/write, 0.6W at idle, and 0.13W in Standby and Sleep. Maximum temperature is 55 degrees C.

Unfortunately the SMART utilities like smartmontools don’t seem to let me grab drive temperature information when it’s in an external FireWire case. So I’d have to install it in order to find out more about it…

So the question is, will installing the drive inside the MBP fry the machine or the drive? Will the fan run continuously? Will the machine be way too hot to put on your lap? Or will I be forced to use the drive externally? (I know of one person who’s had the same drive installed in their MBP, but haven’t had any adverse affects)

I note that the largest BTO drive Apple offers in MacBooks is 320Gb. Is that because they’re the only drive to run cool enough?

OpenSolaris 2008.11 includes “Time Slider”

Interestingly the latest version of OpenSolaris (2008.11) includes a feature called “Time Slider”, which allows you to drag a slider to get to an older version of the file system state. I’m not sure if this leverages ZFS’s features or if it’s just hard-linked. Comments on the Javalobby site by Roman Strobl indicate:

Btw I believe what we have in OpenSolaris is better than time machine because a) you don’t need to use an external disk, b) the snapshots are immediate and don’t consume extra space other than differences from your current disk contents c) you don’t have to activate the backups, they happen automatically. So you also get more granular access to history. This is the first version of the feature so we plan to improve it in the next release.

HFSDebug 4.0 released

The ultimate Mac OS X hacker, Amit Singh (last I heard, snapped up by Google) has released a new version of his HFSDebug tool (that’s a commandline tool folks :).
The new version has more features to do with hard links and hard link chains, new filters, component-wise path lookup from scratch, and is now Snow Leopard compatible (even if it is still only a PPC binary running under Rosetta 🙂

MacBook Air SSD drive comparison

The folks over at StorageMojo have a battery life comparison of MacBook Airs with hard drives and SSD drives. Also a comparison of MacBook Pros with and without SSD drives.

Anybody with a MacBook Air with SSD care to comment if they’ve got a /.hotfiles.btree file on their machine? This would possibly indicate that Mac OS X is still shuffling around their file system to optimise file access as if it was on a hard drive.
