An hour later I'm still playing Super Stardust Delta.
Reported capacity to the OS would match the advertised one, but attempting to… The new Air also supports Bluetooth Low Energy, although without any Bluetooth LE devices on hand I was unable to test the feature. Testing at the same distance I tested the MacBook Pro and iMac at, the results drop to 116.8Mbps. In practice this results in peak performance over 802.11n at around 128.8Mbps. The WLAN solution in the Air is capable of up to two simultaneous spatial streams, topping out at 270Mbps. Unlike other members of the 2011 Mac family, the MacBook Air retains a WLAN stack with 2 receive and 2 transmit antennas via the Broadcom BCM4322. Compared to last year's MacBook Air (Toshiba) you get a huge boost in sequential read/write performance. In regular use I doubt you'd notice a huge performance difference between the two, but if you want the fastest drive you want the Samsung. The Samsung drive has much better random and sequential performance, maxing out the 3Gbps interface when it comes to sequential reads. The SM prefix indicates a Samsung drive while the TS indicates Toshiba:īoth controllers are limited to 3Gbps operation (neither company has released a 6Gbps controller) but performance does vary pretty significantly between the two:Ģ011 MacBook Air SSD Performance Comparisonġ3-inch MacBook Air (Mid 2011) - Toshiba SSDġ1-inch MacBook Air (Mid 2011) - Samsung SSDġ1-inch MacBook Air (Late 2010) - Toshiba SSD You can tell what controller you have by looking at the model string in a System Report from your machine. My 13 had a Toshiba based drive while my 11 had a Samsung drive. While Toshiba and Samsung may not perform as well as the aforementioned controller makers, they've definitely had fewer issues.
Toshiba and Samsung offer much better pricing and don't mind being silent members of the supply chain. Using a custom form factor, Apple partnered with Toshiba (and later Samsung) to build value SSDs for the MacBook Air line.Īlthough Apple has tested solutions from Intel, Marvell and SandForce, to date it hasn't opted to ship any of them to market. Last year's MacBook Air was the first Mac to ship without a mechanical hard drive or an option to install one.
