Hi all I'm curious as to what speeds you are getting with your lacie 2big thunderbolt 2 external drives. Mine is the 2x 3tb version in RAID 0 with the lacie monitoring software on which slows it down a little. Blackmagic tells me my write / read speeds are approx 200mb/s and 300mb/s. I never tested the drive empty but tests I've seen have had write speeds of 300+. Its connected to a mid 2015 rMBP with 500gb pcie SSD. It seems a little slow for a thunderbolt storage solution. I was hoping for closer to the advertised speeds but am wondering if the data I have on it is slowing it down. I have around 1tb of data on it. Let me know what you're all getting with data on your drives, cheers!
