## Description

Review: 1500 dhs it’s worthy - Very Good Product But It’s not supported with MacBook Pro 2015 I was very conservative about this product because it was too much expensive but I make my heart big and I buy. When it didn’t connect with my MacBook i was sad. Then I tried with MacBook Air 2021 and it was working them.
Review: Good product - Thank you so much it is a nice product. I found some issue with shipment but that were related to the courier services

## Questions & Answers

**Q: What is the significance of 40gbps if the drive can only transfer at 2700mb/s? isn't only around 7% of 40gbps?**
A: Drive transfer is 2700 MB/s (mega bytes/s), since 1 byte=8 bits so 2700 x 8= 21600 mb/s, which is more than 50% of 40 Gb/s Thunderbolt

**Q: Will it work with the new iPhone 15 Pro Max for recording video direct?**
A: Unclear. I’ve ordered an iPhone Pro Max but cannot even find information about whether or not it will work at speed with Thunderbolt 4 cable. Apple only says that it is “compatible” while it mentions specifically other devices like MacBooks that would benefit with top transfer speeds up to 40GBps.

**Q: imac 2017 model 10.13.6 - nearly to of memory - will this work on my older iMac?  Connects ok to the ports (no idea what they're called)...thanks!**
A: It’s my understanding that Apple’s Thunderbolt ports are backward compatible. So it should work. But you won’t get the full speed this drive is capable of delivering. This is a Thunderbolt 3 design.

**Q: Need to back up 500gb of 2012 MacBook Pro; would this be a good choice to do so? (No lightning/usbc port)**
A: It wouldn’t, no. I had no luck using it with a USB-C to USB-A cable, not adapter. I tried several brands/kinds, but none worked. If I recall, TB 1 and 2 don’t offer power output, so you’re out of luck there as well.

Though, if you want to spend an unreasonable amount of money on this, plugging the drive into a TB3 or 4 dock and connecting that dock to the laptop using a TB3 ->TB2 adapter may work.
