Picking up a late 2013 13" MBP for my wife recently had me curious as to my MBPs disk speed, as I was pretty impressed with hers at >600MB/sec, and the newer MBPs with > 1TB/sec read/write. Current system is a early 2011 BTO, 2.3 GHz i7, 1680x1050 matte screen, now 16GB, and had replaced the 'primary' drive with an OWC Mercury Electra 6G 500GB SSD, + drive doubler + 1TB backup drive. Besides when initially purchasing, I don't generally benchmark my laptops, especially if there's no known issue I'm chasing, but I went ahead and did so after seeing the 2013's SSD performance. I'm not so thrilled with what I saw, but am at a loss as to the 'why', as third party older reviews seem to put the OWC and even the Samsungs (SATA 6Gb/sec bus) as relatively close 'enough' to each other, but I'm seeing only ~150MB/sec read and write speeds via Blackmagic, which isn't near saturating the interface. BM is a somewhat 'unusual' disk benchmark - for apple to apple rough comparisons, it's fine - I'm just using the PAL scores for reference at 153MB/sec for both read and write. I'm having a hard time believing that's the best it gets on the bus, as theoretical max for SATA III 6Gb/sec = ~ 6000000000/(8 * 1024000) = 732MB/second. No doubt rounding 'license' has been taken in manufacturers favor, but still ~600MB/sec should be achievable. Anyone else have a similar system with the same drive for comparison? Trying to sort if something's off here with my system, especially as if I decide to pass on the next MBP updates, I'll be looking to pick up a 1TB SSD to tide me over for a few. The system performs reasonably well, but this is curious..
