Watch: Apple's 2016 MacBook vs. 2015 MacBook in speed test comparison
kpom said:appex said:"We started off comparing the SSD speed which was faster and more consistent in the new MacBook".
Which values? 947 MB/s read and 845 MB/s write as reported here?
Apple's updated MacBook is indeed faster with longer battery life

But SSD inside MacBook are from Toshiba as reported here:

Yet, latest Toshiba catalog (March 2016) does not have such SSD with 947MB/s read and 845MB/s write but half such values (!!!):

In other words, RAID 0 in Toshiba SSD inside MacBook? RAID 0 is not good, because if one disk or the controller fails, all is lost.
-As iFixIt discovered, there are two SSD MLC NAND Flash chips inside the MacBook (see above), which strongly points to RAID 0.
- If it is a custom SSD, it would be revolutionary, since no other manufacturer has such development with such 2x read and 2x write speeds when compared to competitors (400 to 500 MB/s read/write speeds), not even the current SSD leader (Samsung).
- Toshiba (and all other SSD competitors) are considered years behind Samsung in SSD innovation and deployment.
- For sure Toshiba would have announced (boosting shares for shareholders) and would be selling such innovation by now if available (millions in benefit and taking the SSD market by storm, displacing all competitors).
- I doubt Apple would choose such top innovation (extremely expensive) for a low-of-line MacBool (cheap in Apple standards). Remember that Apple charges 2x to 3x more price for the very same RAM or SSD (very same make and model, albeit being shocking!) inside Macs. Simply, it does not make sense that this is a custom SSD from Toshiba for Apple MacBook, because then such Mac would cost twice or more than current price (already high). -
