Latest MacBook Pro 15 gets blazing SSD performance thanks to 4-channel PCIe (updated)

4chan

Update: It appears this may be a function of the 1TB drives fitted to both 13- and 15-inch models. The reason for this isn’t yet clear: it may be the drives used offer greater bandwidth.

Benchmark tests by French site Mac4Ever show that the latest MacBook Pro 15 is delivering SSD read and write speeds in excess of 1GB per second. The site repeatedly achieved these speeds when Apple claims only “up to 775MB per second.”

The MBP 15 is able to achieve these speeds because it has a 4-channel PCIe connection to the SSD, in contrast to the 2-channel link on the MBP 13 and MacBook Air models, though from some reader reports this may be the case only on models fitted with 1TB drives …

Teardowns of the new  13-inch and 15-inch MacBook Pro models reveal lots of shiny technology, but with the machines following the construction lead of the MacBook Air, it’s no surprise to see IFixIt giving both models low scores for repairability. The extreme difficulty in removing both battery and trackpad mean both models get even worse scores than the Air, at just 1 out of 10.

As with the Air, RAM is soldered directly to the logic board, so if you think you may need more in the future, take a deep breath and pay Apple’s price for the 16GB upgrade as there is no way to upgrade it later. IFixIt also draws particular attention to the difficulty of replacing the battery,

The lithium-polymer battery is glued rather than screwed into the case, which increases the chances that it’ll break during disassembly. The battery also covers the trackpad cable, which tremendously increases the chance that the user will shear the cable in the battery removal process.
