At that rate (100+ MB/sec) your are likely running into issues with the disk pipeline if you are not using solid state storage.
Are you kidding right? SATA ATA hd's and interface supports between 1.5 and 6GB/S. I tested on brand new DELL XPS 8500 with 2TB hybrid drive with latest SATA specs.

My understanding of hybrid drives (I have a 500GB Seagate in a laptop) is they cache frequently requested system files, which greatly speeds up boot, app launching and common system operations to SSD performance levels. But, when doing one-off file transfers, you're going to be writing directly to the spinning platters on the HDD, which will never saturate even 1.5Gb/s (note, it's not GB/s).

I tested the Lexar 1000x 32GB with my Lexar USB3 dual slot reader on my Retina MBP writing to the internal SSD and it went well above 120MB/s, typically at 130 or 140MB/s.

Yes, mine tests are matching RG's on Lexar USB3 reader which is not as quick as mine Kensington USB3 reader. Also I don't think USB3 is faster than SATA especially latest generations, no way. It is pretty quick card no doubt.

130-140 sounds great... but I will wait another generation before updating my USB2 Air. Bought the TB-FW800 adapter and use it with my old Sandisk FW800 CF reader. With the Transcend 600x UDMA6 cards I'm only getting about 60. Still, it's better than the typical 20ish with USB2.
BTW, USB3's theoretical throughput is 5Gb/s. The fastest current SATA is 6Gb/s. Thunderbolt is 10..
