5.0 out of 5 stars An excellent addition., 1 Aug. 2011
Verified Purchase(What is this?)
This review is from: Freecom 35296 Quattro Docking Station for 2.5/3.5 Inch SATA Hard Drives - Compatible with USB 2.0/FireWire400/800/eSATA (Personal Computers)
I'm really pleased with this bit of kit. It's the cheapest disk interface I've found with USB, FW400, FW800 (two ports) and eSATA, and is ideal for checking what's on the bare drives that one accumulates. It can also be put in a FW800 chain, as it has two FW800 ports on the back.

I recently used mine when copying a nearly full 1TB hard disk to a new 2TB hard disk. Because of the extremely large number* of very small files, the copy took seven days to complete. The drive in the dock was being read and written to nearly constantly over that time, and did not overheat. The way the disk is held upright with no enclosure around it allows the heat to dissipate by simple convection quite effectively.

Testing the speed of the dock, I got sequential read speed of 56-126MB/s under FW800 and 102-177MB/s under eSATA, and sequential write speeds of 90MB/s under FW800 and 150MB/s under eSATA.

Highly recommended as an addition to anyone's kit list.

Your copy should have taken about 7 hours via Firewire 800. Which interface did you use?

If it had been a few very large files, it probably would have taken around 7 hours. But it was over 58 million files. That means that access speed of the disks comes into play more than raw transfer speed. Let's assume optimum access - one to read directory data, one to read file data, one to write directory data, one to write file data. Let's say 5ms access time (quick!) let's allow read/write accesses to overlap, since they're on separate disks. That's still at least 10ms per file copy. 58,000,000 file copies, that's 58m*0.01 = 580,000 seconds = 6.7 days...

I'm still very pleased with the dock. An excellent bit of kit.

The Firewire 800 interface is itself limited to a maximum data rate of (around) 80-95MB/s - so not sure how you would get anywhere near 126MB/s...

That's a very good point. I don't know how I got that either! It must have been a measurement artefact on a small transfer. I don't have my notes on the tests I ran anymore, so I can't say exactly where that figure came from.

Someone else commented this does not work with drives larger than 2Tb - I wanted to use it with a 3Tb drive - does it say anything in the instructions that came with the drive?

I can't find anything on the product box about maximum disk size, and I don't have any of the documentation (on CD) to hand. I certainly havent tried mine with >2TB drives.

It's ambiguous - seems some devices do have issues with drives over 2TB - but the description on here and the manufacturers site says 'any' drive. What puts me off is another comment specifically said they had problems - guess worst case it can be returned but I'd rather know before ordering. Thanks for looking though.

Downloaded the manual and it says you can have partitions up to 16TB using NTFS or HFS+ - so again not sure if they mean that is what NTFS or HFS+ support or if the dock can support drives up to that size. There is an image uploaded of that specific part of the manual.

*UPDATE* Emailed Freecom and they said it does NOT support drives over 2TB.
