SSD is solid state drive. Apple is offering a 64 GB drive as an option on the MacBook Air. An SSD is a flash memory based hard drive which is similar to the type of memory cards that you may have in a digital camera or cell phone. An SSD has no moving parts, unlike conventional drives.

The advantages of SSD over conventional hard drives are that SSDs tends to be more robust since it has more moving parts and it effectively eliminates hard drive failure. Also SSDs have faster seek and latency timings and are silent.

Overall, if you can afford it, it is recommended to splash out and go for the SSD option, especially if you plan on using it for work. Just the increased dependability of the hard drive is worth it.

Apple has released more details on MacBook Air. It has a full sized keyboard that has a back lit LED. A 13.3 inch with built in iSight (iSight is a built in webcam). One of the newer and more innovative features is a new and improved trackpad that is not only larger but also has support for multi-touch. This means that you can use shortcuts for such features as zooming in and zooming out, which is the same technology available in iTouch and iPhone.

There will be four possible combinations that will be available to order. The options are regarding the hard drive and the processor. The hard drive comes in two flavors: a 80GB hard drive (same one in iPod) and a 64 GB SSD (more on this in another post). The processor also has two options: a 1.6 Ghz or 1.8 Ghz Core 2 Duo.

Apple has finally dispelled the rumors and announced the MacBook Air. The rumor mill had been working overtime predicting the MacBook Air, amazingly the rumors correctly foresaw the name of the laptop.

My first impression is that its flat out stunning. Its a mind bogglingly thin 0.16 inch. Apple did not skimp on a thing in making this machine. The details are yet to emerge, but we'll keep you posted as they come out.
