New Apple MacBook Air 2010 Stripped Naked, Receives Low Repairability Score

@ 2010/10/22

The new MacBook Air is an exercise of proprietary engineering. While you can easily access everything once you remove the proprietary screws, you can't really replace any component with an off-the-shelf part, unless you source it from Apple or someone involved in Apple-based repair (*cough*). Most components - RAM included - are soldered to the logic board, preventing them from being replaced.

might be X-bench HDD test not up to snuff compared to IOMeter;
it doesn't seem to be the "A" version of the JMicron, which is a good thing.

the Benchmark review puts the SSDNOw+ also at the lower range of the performance ranking http://benchmarkreviews.com/index.ph...1&limitstart=7

but imho, what's more important than performance?

reliability. I sincerely hope that these Toshiba controllers are up to snuff

Eh, don't know what's up but this is what I found :

Read elsewhere that Toshiba uses a custom JMF612 design.

cpu, gpu, ssd and memory are not replaceable at all, unless you bring a soldering gun.

JMicron controller

where? this is using Toshiba's T6UG1XBG Solid State Drive controller, not JMIcron! http://benchmarkreviews.com/index.ph...1&limitstart=3

Using X-Bench, we saw the 128GB model—the APPLE SSD TS128C—give the following numbers:

Seq Uncached Write: 134MB/sec (4k blocks)
Seq Uncached Write: 158MB/sec (256k blocks)
Seq Uncached Read: 68.5MB/sec (4k blocks)
Seq Uncached Read: 165.8 MB/sec (256k blocks)

Random Uncached Write: 32.18MB/sec (4k)
Random Uncached Write: 116.5 (256k)
Random Uncached Read: 8.27 (4k)
Random Uncached Read: 108.56 (256k)

Random write of 32Mb/s at 4k is pretty darn impressive imho

That custom made SSD looks like its a pain in the a.. to replace, since it's made only for these Macs.
It is one of the things I dislike about these new Macs
