This review is from: LaCie d2 4TB USB 3.0 / Thunderbolt External Hard Drive 9000303 Silver

Pros: This drive does exactly what the hardware is capable of.

Cons: None.

Other Thoughts: Thunderbolt has 10Gb/s of bandwidth which is very necessary when it is being daisy chained with other devices. Theoretically I believe Thunderbolt being a managed connection can transfer 1.25GB/s. Yes GigaBYTES per second. What that means is that even if you have Sata 3 in your computer and and two SSDs in Raid 0, Sata will run out of bandwidth before the Thunderbolt since Sata 3 is 6Gb/s. The point is so you can have multiple hard drives, monitors, etc all running off of one port. That is the purpose of the ridiculous (relatively) bandwidth. There should be no difference or extremely small difference in speed with this disk using a USB 3.0 or Thunderbolt connection since they both have a higher bandwidth than the disk is capable of. The point is you can daisy chain 8+ of these off the same connection using Thunderbolt and not hit a bottleneck.

The short version:

It is like putting 200mph rated tires and wheels on a Prius. The car (the hard disk, or data storage device) cannot put out enough power (Read/Write fast enough) to meet the speeds the wheels (bandwidth) are capable of.

This review is from: LaCie d2 4TB USB 3.0 / Thunderbolt External Hard Drive 9000303 Silver

Pros: You will NEVER see that 10Gb/s, that is the maximum throughput that the Thunderbolt port is capable of, the hard drive inside this external unit is still a spinning platter drive, so, since it is the slow point, you might get to see between 50-100Mb/s in transfer speeds. It's the hard drive inside that's slowing it down. Use an SSD in a thunderbolt enclosure and you will see 3-5 times that speed.

Cons: None

Other Thoughts: People should read up on technology before buying it!

1 out of 5 eggsNot what I expected...

This review is from: LaCie d2 4TB USB 3.0 / Thunderbolt External Hard Drive 9000303 Silver

Pros: Half of the speed transfering time comparing of an USB 2.0 external drive still better than nothing but the Thunderbolt wasn't 10X faster than USB 2.0

Cons: Copy and Paste or just transferring a single 50gb ISO file takes ~11minutes using thunderbolt connection on a Mac Pro I7 nov.2011.Comparing to my other Seagate USB 2.0 doing the same taking 27minutes. So, for 10X more speed than USB 2.0 I was expecting much less transferring time than I got. maybe I need to change something in my Mac Pro...

Other Thoughts: How to reach 10Gb/s ?
