![]() Testing conducted using Iometer 2006.07.27 with a 30-second ramp-up, 5-minute run duration, 512KB request size and 8 outstanding IOs. All units were configured with 4GB of RAM. 750GB 5400-rpm hard drive was tested using production 2.4GHz quad-core Intel Core i7-based 15-inch MacBook Pro systems. 1.6GHz dual-core Intel Core i5-based 11-inch MacBook Air units with 128GB of flash storage and 1.7GHz dual-core Intel Core i5-based 13-inch MacBook Air systems with 256GB of flash storage were production units. Testing conducted by Apple in May 2012 using preproduction 1.7GHz dual-core Intel Core i5-based 11-inch MacBook Air units with 128GB of flash storage and preproduction 1.8GHz dual-core Intel Core i5-based 13-inch MacBook Air units with 256GB of flash storage. this next-generation flash storage is up to 4x faster than a traditional 5400-rpm notebook hard drive and faster than the previous-generation MacBook Air.2 … Apple never advertised the throughput for their drives except for this: And yes, it IS “extremely fast” even with the ~60MB/s discrepancy. I sure as hell wouldn’t be complaining with the 260/440 numbers. Hell forget that, just donate it to someone who’ll appreciate the device more who cares less about the bandwidth numbers, so long as it performs substantially better then the previous generation MBA! Seriously? you’re going to complain about 60MB/s throughput as compared to the previous generation MBA’s SSD? I say return it explaining that the SSD is too slow then they claimed it is supposed to do despite the fact that the claim is vague with an “up to” statement. Z0M6Z !!! My SSD is ~60MB/s slower “comparing the most up-to-day SSDs”. I need to buy a mac and I’m thinking Air especially for SSD speed, if and only if this speed does not drop too much in time. However, I think Apple might have addressed this issue in the OS (perhaps with a kernel module to optimize/wipe data preemptively or something), seen as how much more attention they pay to details, in which case I could enjoy this speed all the time. Now most of these tests were either performed on winblows or Linux, where I’m pretty sure no one had the time (to market) to supply a workaround(kernel patch/daemon/windows special driver). If let’s say the read / write speeds drop in half, that’s still better then any HDD, but from what I read, the speed drops to about a mid range HDD. Dig into it to find out more and for those of you who have SSD macs for over a year and using the file system extensively please share with the rest of us a benchmark result. You may recall that Apple also ships faster Samsung drives in some MacBook Airs, that appears to still be going on with the 2012 updates which suggests the tested Toshiba flash drive is probably slightly slower than a Samsung model, though the performance difference between the two drives is likely to be completely negligible at this point.Īll read and write speeds were benchmarked with DiskSpeedTest, a free disk testing app available from the Mac App Store.Ĭan anyone tell me whether they have some sort of daemon workaround for the situation when the whole disc gets full and you need to write over a previously written area? You all know (i suppose) the major SSD flaw is that you will be enjoying that speed only until the last byte of that SSD has been written to, after which time major slowdowns will occur. The SSD tested with the MBA 20 models are Samsung. Interestingly, the SSD tested within the MBA 2012 is the TS128E model, a Toshiba drive. You can attribute that to the ultraquick flash storage. It is difficult to convey just how fast the newest MacBook Air is, but it’s safe to say the performance is extremely impressive and I haven’t ever used a laptop that feels faster. ![]() MacBook Air 2010 SSD: writes at 157MB/sec, reads at 188MB/sec MacBook Air 2011 SSD: writes at 152MB/sec, reads at 145MB/sec MacBook Air 2012 SSD: writes at 364MB/sec, reads at 461MB/sec
