System memory, but it meant that physical RAM was no long an absolute Then came virtual memory, which allowed you to reserve a certainĪmount of space on the hard drive where you could swap data from RAM to If you ran out of memory, you had to quit In the old days, personal computers had a certain amount of memory What is going on here? How can SSD make such a difference? Virtual Memory This year's 1.86 GHz model achieves 2695,Īnd the 1.4 GHz model comes in at 2026, approaching results for the Outperforms its predecessor in processor intensive tasks," according toĪnd Macworld is not alone. Quantum leap from previous versions, yet "the new 1.86 GHz MacBook Air Those tests aren't supposed to be impacted by hardĭrive performance, the Core 2 Duo CPUs in the new MacBook Air are not a Other tests, the new drives came in at 21% faster.īut the surprising thing is that the processor intensive tests also
Model's hard drive as with the 2010 model's solid-state drive (SSD). That duplicating a 1 GB file took five times as long with the 2009 The biggest change in the MacBook Air is the move from slow 4200 rpmġ.8" hard drives to flash memory for data storage. The 2.13 GHz version, 63.ġ3" MacBook Air, it benchmarks at twice the performance of last year's 1.86 GHz model. The raw numbers are there: The 11" MBA has an overall Speedmark 6.5 In fact, it scores a lot higher than last year's 2.16 GHz Macworld's benchmark report on the new MacBook Air (MBA) modelsĬomes as something of a shock when you consider that it applies to theĪir. "The new MacBook Airs are faster than their predecessors." Make a mental note that it's connected to the system board via Where this column refers to the SSD as being on the system board, Using 3 Mb/s SATA II, although the company has not confirmed that. The operating system as SATA drives, and it appears that Apple is I had originally believed, but use a new connector, which means theyĬan be replaced. The SSDs are not soldered to the system board, as Since publishing this column, more facts haveĬome to light about the 2010 MacBook Air (MBA) and its solid-stateĭrives (SSDs).
