OWC upgrade for 27-inch Apple iMac now offers 3.0TB hard drive option along with SSDs configs

Apple StoreOther World Computing (OWC) announced today its OWC Turnkey Upgrade Installation Program for the Mid 2010 Apple iMac 27″ now offers iMac owners the option to upgrade the hard drive to a 3.0TB model — a 50% storage capacity increase over the 2.0TB factory option.

This new storage capacity option joins existing upgrade program choices:
• Adding up to three OWC Mercury Extreme Pro SSDs for up to a total of 1.44TB capacity – up to 5.5X higher than the factory SSD option
• Adding the first offered eSATA port option for an iMac
• And/or adding up to 16GB RAM with savings up to 81% versus factory options.

The turnkey professional installation service program offers multiple configuration options starting at US$169 with a 48 business hours or less installation turnaround and includes complete shipping options along with OWC’s renowned warranty coverage.

OWC’s upgrade process:

1. Start by adding the only available eSATA port offered for the iMac for $169. OR, add an OWC Mercury Extreme Pro SSD up to 480GB in capacity from $319. The eSATA (External Serial ATA) port upgrade provides faster data backup and transfer rates up to 300MB/s…up to 3X faster than FireWire 800, the fastest factory stock interface.

2. Choose additional OWC Mercury Pro SSDs for up to three total SSDs and up to 5.5X higher capacity (1.44TB total vs 256GB) than the factory SSD option while retaining use of the internal optical drive. OWC SSDs offer read/write speeds in excess of 270MB/s, up to 40% faster than the factory and many other currently available SSDs.

3. Replace the stock HD with a High-Performance 2.0TB or 3.0TB hard drive while utilizing up to two OWC SSDs and/or eSATA port option.

4. Add OWC RAM up to 16GB with kits providing 8GB total RAM starting from $75. OWC memory kits for the iMac are Lifetime Warranted and offer savings up to 81% compared to same size factory available upgrade options.

When three OWC Mercury Extreme Pro SSDs are user configured in RAID 0 array, the up to 770MB/s read/write speeds effectively turn an iMac into a true performance workstation that easily handles the most demanding data intensive needs.

  1. I have an OWC SSD in the 2nd optical bay as my boot drive for my MacPro & one as the internal in my Aluminum 13″ Unibody MacBook.
    BTW- anybody know why the SSDs report drive temps @ ONE Degree Celcius? Is is OSX or what?

  2. Is says one degree because SSD’s are still trying way too hard to be cool. The reality is they’re too small, overpriced and amount to personal computer glitz. It boots up faster sure, but you needed that feature 12 years ago more than you do now.

    SSD is significant, because it allows nearly instant access to any part of the storage with no delay caused by moving parts or fragmented data. Nothing needs to be “cached” for faster access; you can think of the entire SSD as being “cached.” It’s true that “boot time” is mostly irrelevant for Mac users these days, but that speed also allows nearly instant wake from sleep (at least for MacBook Air) and general improvements in speed, such as for launching/running applications.

    I compare running a Mac from an SSD to the old days when you could allocate part of your RAM to make a RAM Disk, copy your system to it, and boot from it. That made the Mac quite a bit faster, compared to starting up normally, and nothing changed except for the Mac’s primary storage.

    Ultimately, SSD’s are going to cost less per GB and allow higher storage capacities, compared to hard drives, because an SSD is much less complex compared to a hard drive. A hard drive is a fragile and complex mechanism with many tiny moving parts. It’s like a fully mechanical watch compared to a quartz digital watch.

    In the meantime, the best way to use an SSD economically is to get a relatively small capacity SSD (such as 120GB), mount it internally, and use it mostly for your Mac’s system and application storage. You can keep a small user home folder on it, but store most of your large categories of data (such as your iTunes media files, iMovie projects, etc.) on a secondary drive. With these new iMacs, you can have one SSD plus a second larger internal drive; you also also use an external drive for your data storage.
