| 1113491 | 2010-06-25 05:22:00 | Hi, I have a SATA-2 on a Vantec HD Dock - it has eSATA and USB2. If I copy a file, like a 3GB single ISO file from the PC to the external HD (not doing anything else) it provides 30MB/sec. Which is the same speed as using its USB2 cables instead. Win7 Pro x64, no drivers loaded. If I copy the same file from internal HD 1 to internal HD 2, I get 90MB/sec. :confused: Cheers... |

| 1113493 | 2010-06-25 06:10:00 | If I am getting only 30MB/sec is that on the slow side? Possible to get it faster like it's spec'd up to 3Gb/sec? | Nomad (952) | ||
| 1113494 | 2010-06-25 08:17:00 | If you are relying on the speed windows states it is transferring at, I think that is pretty unreliable. When I recently bought a USB3 enclosure I did some tests timing the copying a 5.16GB iso file. Here are the results USB2 took 183 seconds eSata 92 seconds USB3 82 seconds |

Your stats at least shows eSATA is not as quick as a internal drive - well as their quoted 3Gb/sec. |

| 1113496 | 2010-06-25 11:43:00 | The fastest speeds quoted for connections such as Firewire, USB2/3 and eSATA are only "burst" speeds that only occur right at the start or at times during the transfer. Other than that, it'll be much slower. | beeswax34 (63) | ||

| 1113498 | 2010-06-26 01:27:00 | For eSata and USB3 the speed of the transfer will be affected quite a bit by the speed of your hard disks and where on the hard disk (both source and target) the file is located. For USB2 the Hard Disk should be faster than USB2's maximum transfer rate. | McRuff (12291) | ||
| 1113499 | 2010-06-26 02:56:00 | I have a pair of these Vantec HDD docks (NexStar). Copying a 3GB file from a WD AAKS in one of the docks to a partition on the system disc averaged 95 MBps (varied 93 - 107) (GA-P55A-UD3 using genuine eSATA port, i5-750, W7pro64) |

| 1113500 | 2010-06-26 04:55:00 | I did my test again with a stopwatch. 2.34GB - single ISO file. 32sec Internal to Internal. (SATA-2) 58 sec - eSATA (SATA-1) 1min 40 - USB2 (SATA-1) :clap I tested it with a SATA-1 drive, my SATA-2 drive was a pull of my RAID-1 so Windows couldn't read it in Explorer. I assume the SATA-1 wouldn't be the bottleneck. |
