MacBook Air was revolutionary even at the time it was Apple introduced, but now, even after years that we have known it, it has become revolutionary again. The main novelty of this year's model Apple introduced neither longer battery life, nor dual microphone or Haswell processor. The real revolution must be sought in the SSD disk that the novelty has acquired. If we look at the development of memory speeds in Macbook Air Until now, computers have always undergone more of an evolutionary change, but this time it has seen a real revolution. If we look at the new generation of so-called unibody MacBook Air We have encountered four machines so far.
- MacBook Air 2010 – writing: 157MB/s, reading: 188MB/s
- MacBook Air 2011 – write: 152MB/s, read: 145MB/s
- MacBook Air 2012 – write: 364MB/s, read: 461MB/s
- MacBook Air 2013 – write: 794MB/s, read 764MB/s
As you can see, while the first three generations of uniboody MacBook Air we meet at a reasonable speed, the new generation offers a real leap forward and not only within the range of computers MacBook Air, but within SSD memories in general. The typical speed of the fastest memories available today is maxat least 560 MB/s, both when writing and reading. If you want to look a little higher, you can of course, but your choice will not only be significantly limited, but it will also become more expensive. If you want to exceed the speed below 600MB/s, you have to exceed it three times and get to the Intel SSD 910 series, which offers an incredible read speed of 2000MB/s and a write speed of 1500MB/s. However, here you can expect a price of 45 CZK for a 000GB disk. The vast majority of manufacturers simply do not offer anything in between.
AppHowever, Lu managed to pull off a really cool stunt by offering a drive with a speed of almost 800MB/s even on its cheapest model. MacBook Air with a starting price of 25 CZK. MacBook Air According to tests, it actually has a disk with a read speed of up to 794MB/s and a write speed of up to 764MB/s. All this in real conditions, not just on paper.
The first thing that occurred to me when I saw the speeds was that the purchase of the Israeli company Anobit had paid off and was starting to bear fruit. However, when iFixit took apart the first iPhone of the year MacBook Air, we found that there is no logo of any company other than Samsung in mind. MacBook Air with a 128GB SSD disk, it specifically offers storage consisting of 8 memory modules Samsung K9LDGY8SYC-XCK0 with a capacity of 16GB. Even the controller itself, which takes care of connecting the individual modules into a single unit and then to the rest of the computer, comes from Samsung. Apple Although it switched from SATA to PCIe connection, it has not yet used its own memory and for the speed of this year's MacBook Air As for the disk, we really owe it to Samsung.
Personally, I think that the speed of flash memory is MacBook Air a decisive factor that affects the overall speed of working with the computer for the vast majority of users. MacBook Air It is a machine on which the vast majority of users do not perform any calculations, but the number of times the application icon jumps in the Dockuntil the application starts.

So I see a jump already in 2012. I think that the revolution is in the use of PCIe, of course, in combination with excellent memory modules
With those memory modules, it's a matter of consideration, because they are made by Foxconn anyway, like 99% of other modules. Samsung is most likely just a "vendor" in this case.
I agree with JK
PlugIN: Foxconn componenty does not produce, it is only an assembly plant, completes equipment from a computeronentov. Those memories are developed and manufactured by Samsung.
