  • SSD and USB 3.0 Performance Benchmarks for New MacBooks Released


    It was a given that Apple’s Macs would be receiving performance improvements courtesy of new SSDs and USB 3.0 at WWDC. The folks over at AnandTech were able to benchmark the data for the two new features courtesy of a review unit of the new MacBook.

    It was rumored that the updated MacBook would be receiving Samsung’s 830 series SSD. The report from AnandTech seems to be consistent as they narrowed down the choices to the 830 series as the most likely scenario noting the review unit appears to be approaching a read speed of 500 MB/s with a write speed of roughly 400 MB/s. Below is what the report mentioned regarding the SSD:

Based on the model number in Apple’s System Report I’d guess my review sample features a Samsung based drive… I ran a few tests using Quick Bench to validate Apple’s claims. In general it looks like read speed approaches 500MB/s, while sequential writes are closer to 400MB/s


    As far as USB 3.0 performance goes, there seems to be quite a performance boost from USB 2.0 from the early 2011 MacBook Pro model. Below is what the report mentioned regarding USB 3.0 performance:

    Those of you who waited around for an upgrade won’t be disappointed with the results!

      Very few PCs with SSDs get 500+

      You also must pay attention to the size of the file. A limitation with USB is that it overloads it's own buffer with larger files, which can show some fluctuation in the file transfer. This, in turn, will create a lower average. However, ^ this guy is spot on. VERY few PCs will see that speed.. and definitely not through USB3..

      ADATA SSD's are the only Sata SSDs that I have seen get over 500MBps, of course PCI-E SSDs will get higher but they cost in the thousands.

      the first benchmarks are hard drive based not usb, so buffering has nothing to do with it, it has to do with the choice of ssd they are using. and again depending on what ssd you use in ANY pc you will see 500 easily, and no i don't mean commercial grade expensive drives, several consumer grade drives easily hit these speeds just depends on what controller the ssd uses and the IOPS it is capable of.
