New iMacs To Use SSDs As A “System Cache” For Spinning Hard Drives?

Yesterday, we noted the new iMacs featuring Sandy Bridge processors and Thunderbolt technology came with an option in the Apple Store’s online configuration page to pack a hybrid Serial ATA Drive + SSD setup at an additional cost. What’s curious about this hybrid setup is the note left by Apple to inform users that OS X will come preinstalled on the solid state drive, leaving space for documents and other media on the bigger (but slower) spinning hard drive.

iMac also offers an optional 256GB solid-state drive (SSD), which has no moving parts and delivers increased drive performance for many operations. The 256GB SSD can be purchased in place of the standard hard drive or in addition to it.

If you configure your iMac with both the solid-state drive and a Serial ATA hard drive, it will come preformatted with Mac OS X and all your applications on the solid-state drive. Then you can use the hard drive for videos, photos, and other files.

This led to speculation as to whether Apple was planning to install OS X on the SSD and show the other drive as a mounted volume in the Finder, or they developed a brand new system to automatically handle the processing of files and system info across the SSD and the spinning drive. Several bloggers and Mac users wondered how Apple could manage to easily allow the new iMacs to quickly switch between drives, save the OS on one drive and media on the other, symlink the user’s Home folder to content saved outside the SSD. These technical questions also had to face the 4-6 week delay that showed up when ordering a new iMac with hybrid configuration. However, the solution may be pretty simple, as it could lie in Apple’s use of Intel’s new Z68 platform, which – combined with the upcoming “Larsen Creek” SSDs – allows for a new caching system called “Smart Response Technology.” Intel’s BD82Z68 Platform Controller Hub is indeed being used in the mid-2011 iMacs, as iFixit confirmed earlier today.

Intel’s Smart Response Technology works like this: in a hybrid configuration such as the one possible in the new iMacs, the smaller SSD acts as a “system cache” for the bigger & slower HDD. The OS (boot files, resources, extensions) are cached on the SSD for faster loading times, but the user only sees one drive in the Finder / Windows Explorer.

Smart Response provides a middle ground between capacious but slow and inexpensive hard drive storage, and fast but small and expensive SSD. With it, one can retain a high-capacity hard drive, and speed it up using a small SSD. The technology uses the small SSD’s low access times and high speeds to make it work as a cache of the HDD, it might even store copies of key parts of the HDD such as the boot volume and system files, to make booting faster, and the system more responsive overall.

It’s not clear at this point whether the delay in shipping times is caused by Apple waiting for Intel’s new solid state drives, and if Smart Response Technology will be enabled at all in Snow Leopard. Apple’s note on OS X coming preinstalled on the SSD surely raises some important technical questions, and we’ll know more in a few weeks when these hybrid iMacs will start showing up. [TonyMacx86 via 9to5mac]

New iMacs: Teardown, First Benchmarks

Following yesterday’s release of the new iMacs with Sandy Bridge processors and Thunderbolt technology, the guys over at iFixit immediately started tearing down a 21.5-inch model. In their official teardown article, available here, there are a few notes of interest: iFixit notes how, design-wise, nothing much has changed in the new iMacs, which can be opened in the same way of the old generation units by pulling off the magnetically-held glass and removing the screws holding the LCD in place. The display is manufactured by LG and it’s the same used in the previous-generation iMac. iFixit also gives the machine a 7/10 Repairability Score, noting that average users can easily replace RAM, but accessing the CPU and GPU requires to take out the whole logic board, which is described as a “tricky process.” The teardown also reveals the Thunderbolt connector is similar (but not the same) to the one found in the early-2011 MacBook Pros; one heat sink is reserved for the CPU, with the other assigned to the GPU.

New iMac Notes: Dual External Display Output, OS X on SSD - No Video Input? [Updated]

Following this morning’s refresh of the iMac – you can read more about it here – a few technical tidbits have started popping up on the Internet causing some interest and speculation from Apple fans and bloggers. Among the new features of the updated line – such as improved graphics, and new Intel “Sandy Bridge” processors – support for the Thunderbolt technology on the 27-inch iMacs has been extended, as the bigger models now come with two Thunderbolt ports to use for data transfer, daisy-chaining of external drives and peripherals and, as noticed and confirmed with Apple by GigaOM, dual external display output. Support for dual display out through Thunderbolt means you’ll be able to connect two external monitors to the new 27-inch iMac, and output the computer’s screen to the monitors simultaneously. This is great news for those who like external vertical monitor setups, and it’s now made extremely easy by the Thunderbolt ports located on the back of the iMac.

One of the most exciting things about today’s new iMacs (and the thing that will probably result in me buying one) are the dual Thunderbolt ports on the 27-inch iMac. They’re great in that they provide a lot of potential I/O transfer power, but more importantly because it allows the new iMac to output to two external monitors simultaneously, Apple confirmed to me this morning.

Achieving a similar setup was possible before, but it required users to buy USB or VGA adapters that resulted in loss of quality and poor performances when compared to native, wired Mini DisplayPort connections. Thanks to Thunderbolt’s daisy-chaining functionality, using both Thunderbolt ports for dual display output doesn’t mean you’ll be forced to constantly plug in and disconnect peripherals: if you own a Thunderbolt-based external drive, you’ll be able to connect it to the iMac, and then plug a secondary display into the drive’s Thunderbolt port. This way, Thunderbolt is used at its full capacity and you still retain the possibility to output to two different monitors simultaneously. Read more

Apple Releases iMac Hard Drive Firmware Update

A few minutes ago Apple released a firmware update for the Mid-2010 21.5-inch and 27-inch iMacs. The update – a 767 KB download – aims at fixing hard drive issues that prevented some systems from booting properly. My iMac surely had this problem – especially after installing Lion on a second partition, I noticed several booting issues that this update will (hopefully) fix.

With iMac Orders Delayed, We’re Expecting a Refresh

CNET’s Brian Tong previously reported at the end of March that now would would be a bad time to purchase an iMac, as a refresh coming in May would bring no cosemtic changes, but Thunderbolt and Sandy Bridge would flesh out the range of Apple’s refreshed desktops. 9 to 5 Mac reports that the iMac is continually seeing supply restraints for the current generation of iMacs, and that a source revealed new iMacs should be shipping next week as Apple stops shipping to resellers this week.

Due to an unexpected delay, we are unable to ship the following item(s)
by the date that you were originally quoted:

Z0JP, IMAC 27\”/5750/SD
will now ship on or before
May 02, 2011

We’re keeping an eye out for May 3rd and 4th delivery dates, and we expect a MacBook Air refresh to include Sandy Bridge processors in June, with Thunderbolt products to hit the mainstream this summer.

iMac Supplies Running Low, Refresh Imminent?

According to 9to5mac, several sources in the United States and Asia have indicated supplies for the current iMac line have become “constrained” in the past week, suggesting that a refresh from Apple is imminent. Tightening of supplies is usually a good indication that a refresh for a product line is coming, and previous rumors indeed pointed to the iMac being updated with new hardware features by late April.

Tipsters in the United States have informed us that their iMac shipments are also very constrained. That’s not the full story though. Although actual iMac shipments are lacking, our U.S. tipsters report that actual iMac components are very constrained. The most constrained pieces right now are the current iMac’s graphics processors and hard drives. A lack of replacement components is also a good indication of an upcoming refresh.

Three weeks ago, Cnet’s Brian Tong claimed an iMac refresh would occur with “no cosmetic” changes by the end of April or first week of May. This seems to follow the path Apple took with the 2011 MacBook Pro update, which showed supply constraints in the weeks leading to the announcement and eventually featured the same design of older models with the addition of Sandy Bridge processors and Thunderbolt technology.

The iMac line was last updated in July 2010 and also saw the release of the Magic Trackpad – which can be bundled with an iMac on the Apple online store.

Expected iMac Update To Sandy Bridge & Thunderbolt To Occur In 4-6 Weeks?

iMacUpdate

With the MacBook Pro line getting spec bumps to Sandy Bridge processors and Thunderbolt, Apple’s iMac should fall in line in about 4-6 weeks according to Brian Tong from CNET. On Twitter, Brian noted that iMac’s were en route for a late April refresh.

EXCLUSIVE: My Sources: New iMacs en route by ocean to U.S. available end of April or 1st week of May. No major cosmetic changes.

My sources say New iMacs will feature Sandy Bridge and Thunderbolt. No other specifics.

The iMac shouldn’t receive any aesthetic changes in this early 2011 update. CNET has also postulated that the MacBook Air would receive an update to Sandy Bridge in June, replacing the much outdated Core 2 Duo processor in the mobile lineup.

What Is Thunderbolt?

Thunderbolt technology is what was Intel’s Light Peak. It’s not an Apple technology, but rather the culmination of Intel’s handiwork in combination with Apple’s mini DisplayPort. While Light Peak was developed to work over fiber (literally for light speeds), Thunderbolt is implemented over copper. Despite this, you’re still getting bi-directional (in and out as they say), 10 Gbps connection over a cable, plus a 10 Watt feed so you can power heavy equipment on the go (you don’t get that with USB). For comparison, your current USB 2.0 devices only get 480 Mbps through the cable! With this technology, you can drive multiple inputs including monitors, workstations, and audio equipment without a bird’s nest under your desk.
