Some MacBook Air now come with SSDs faster than those used originally, the X-Blade Toshiba scabies. They have faster speeds and NCQ support, unlike the early models. The new SSDs have been discovered by members of the MacRumors forum and our colleagues from AnandTech have decided to run some tests published last Friday.
Specifically, Apple is now shipping two models of MacBook Air. Some come with the TS128C, the SSD from Toshiba. Other models have SSD SM128C and it is impossible to guarantee their origin, they are probably manufactured by Samsung. The differences between the two rates is significant. The TS128C has an average speed of reading 209 MB / s to 175.6 MB / s.
In turn, the SM128C reaches 260 MB / s read and 209.6 MB / s write. These new performances are identical to those of the Samsung SSD 470, which reinforces even more the hypothesis of a production by the Korean. As pointed out by our colleagues, ultimately, consumers will receive the SSD that Apple will provide.
The mark does not recognize any change for now and a consumer can not ask for a replacement because it only seeks the SM128C. However, if we take a step back, we realize that the difference, even real, will have a minor impact during everyday use and it is doubtful that the average consumer to make the same account for the difference.
You can still do the test yourself by downloading the free software AJA System Test. You must choose an image size 1920 x 1080 - 10-bit RGB file size of 4 GB is also possible to check the version of the SSD in the System Profiler (Apple -> About this Mac -> More ... Info -> Serial ATA -> Apple SSD).
SSDs with the revision CJAA0201 are normally older Toshiba models, while AXM09A1Q are the new Samsung models. When asked who is to know why Apple did not use SM128C the outset, the answers are many, but can easily think that the firm had a stock she wanted up. It is also highly possible that she decided to call Samsung to Toshiba's inability to cope with demand.
One thing is sure, this has no bearing on the Japanese earthquake, as some MacBook Air bought last January, long before the disaster itself, already had the new SSD.
