Application Tests
Our application benchmarks are designed to show application performance results with times being reported in seconds, with lower scores being better. While these tests will show some differences between the drives it is important to understand we are no longer measuring the pure performance of the hard drive but how well our platform performs with each individual drive. The performance of a hard drive is an integral part of the computer platform but other factors such as memory, CPU, core logic, and even driver choice can play a major role in determining how well the hard drive performs in any given task.
AnyDVD 6.1
Our next test has us utilizing the "ripping" function of AnyDVD to copy the Office Space DVD file from our source drive to our test drive. Our DVD features 29 files totaling 7.55GB of data and is an excellent test for determining the write speed of a drive.
We see the eSATA configuration trailing the internal setup by 3 seconds or about 2% slower. The USB 2.0 connection is 45 seconds behind the internal connection which equates to it being 21% slower. This was expected due to the reduced write/read speeds of the USB 2.0 connection.
Game Load Test
Our Sims 2: Open for Business test measures the time it takes to load the initial portion of the game. Our application timer starts when the game icon is initiated until the neighborhood menu appears.
The results are basically the same with our eSATA connection slightly trailing the internal setup and the USB 2.0 configuration finishing about 13% off the pace although the differences are very minor.
Game Level Load
This test centers on the actual loading of a playable level within our game selections. The Battlefield 2 test measures the time it takes to load the Daqing Oilfields level. Our application timer begins when the start single player icon is initiated and ends when the join game icon is visible.
The internal SATA and eSATA setups are equal in this test with the USB 2.0 connection being around 15% slower. Once again, no surprises in this test.
File Copy Performance
Our file copy test measures the time it takes to transfer our test folder that contains 29 files, 1 folder, and has 7.55GB of data from our source drive to the target test drive. This benchmark is disk write intensive and requires a fast storage system. The second test does copies the same folder on the test drive to another folder on the same drive.
We finish our tests with a benchmark that favors pure write speeds. Our eSATA setup trails our internal SATA system by two seconds with the USB 2.0 connection finishing 151 seconds behind due to the limited write speeds of this setup. In actual operating conditions, our USB 2.0 connection averaged around 26.1 MB/s in write speeds in this test compared to 34.1 MB/s in our synthetic HD Tach benchmark.

What would be more interesting is an enclosure that includes a 1000 or even just 100Mbit LAN, in addition to USB (and possibly eSATA). It'd be invaluable being able to hook to older computers at faster than (theoretic) 12Mbit and to be accessible to multiple computers on the network.paulwatsonjr - Friday, July 13, 2007 - link
On the chart you show that esata is not daisy chain'able (which is true.) However, I thought I remembered seeing something about esata now having some sort of multi-port capability, similar to daisy chaining, that is supported by the latest round of Intel chipsets...Farfle - Thursday, July 12, 2007 - link
There are a ton of these eSata enclosures out there, and all seem to advertise to do the same thing. They probably all do, for the most part at least. I purchased this model from Beyond Micro:http://www.newegg.com/Product/Product.aspx?Item=N8...">http://www.newegg.com/Product/Product.aspx?Item=N8...
The main reasons I chose this over other competitors was the following:
1. On/Off power switch on the front (although, admittedly, kinda useless--not to mention risky--if you're using it as you're system drive, hehe..."Ooops, there goes Windows!")
2. The AC adapter's power plugin is one of those rounded inner/outer types that makes connecting to the enclosure a snap! I always hate trying to allign those S-Video-type power plug-ins to their mates (like on this Icy Dock model).
3. Built-in fan. Some HDs get quite hot, and it's nice to have a fan to keep 'em cool. Also, it appears the top of the Beyond Micro drive has an aluminum cover, which better conducts the heat.
Some bad things about it tho, is installation was kind of unnecesarily complicated. It comes with screws that you need to ensure you utilize, otherwise the cooling effects are minimized, and the noise becomes more apparent.
I'm not trying to "comment" crap here, but just sharing my experience with this particular product type.
*Note - One other thing to think about--that applies to all these eSata enclosures--is the PCI bracket. I bought this drive for use in a Baby-atx Low Profile case (one of those computers that can sit under your monitor...like the good ol' PC days). Unfortunately, none of these enclosures come with a Low-profile bracket. I had to purchase this special one from Addonics for $7 + $7 shipping:

$14 dollars for a stupid little metal bracket is a bit absurd, but I had no other choice (if I wanted to keep the setup pretty). So, unless you have an onboard eSata connection and you're using a low profile computer, you're kinda stuck having to purchase this extra peripheral.

How would performance have been differant had a Western Digital Raptor been used instead of a 7200 RPM Samsung over USB? Could you post some benchmarks?Dave Robinet - Wednesday, July 11, 2007 - link
I wouldn't expect the Raptor to come out significantly better, to be honest. The transfer rate of either drive saturates the bus, though I'd imagine the Raptor would improve things slightly in heavy small file access times (certain games, etc). As I mentioned, though, it likely wouldn't be much - looking at the Load Level Time benchmark in the 2nd last page would be a best case scenario, IMO.Gary's a pretty busy man these days, so I'm not sure I'd count on the benchmarks for the Raptor in the USB this time around. Sorry. :)

Good to find a review of this unit. Now that I started searching around, I see that there are a number of other reviews on it, but I don't check those sites as often as Anandtech.I first saw something similar at a local B&M. It seems to be sold under a few brand names, like Cremax and SohoTank. What sets it apart from others is a hot swappable, removable tray. While you could buy a 250-300GB HDD for the base unit, each additional HDD tray would only set you back $20 or so. If you use external drives for backups, this seems like a better solution than getting individual enclosures for every drive. Advantage : less clutter. Disadvantage : cannot use more than one unit at a time (unless you get more base units, of course).
I really like the idea of an external enclosure with a hot swap tray, but would prefer one that is dampened (less noise / vibration, important when the drive is closer to you) and has active cooling (i.e. a fan). And icing on the cake would be to have USB and firewire ports on it as well. Best bet right now seems be to build one using a mini ITX enclosure. Not having an extra power brick (and an on/off switch that cuts power to the power supply, not just the enclosure) will also be nice.
The short summary about eSATA (how AHCI is necessary for hot swap, etc.) is also useful - something I've been wondering about for a while. Can anyone point to sites with additional info on eSATA, specifically how to add it to an older system without eSATA so that it supports hot swap, any drives that don't play well with hot swap? TIA.

Thanks for the comments.The simplest way to add eSATA to existing systems is with the use of a controller card (as people often do with SCSI). Which OS are you using?
lennylim - Wednesday, July 11, 2007 - link
Mainly XP (Pro and Home) and Linux, though support for Linux now mainly falls under the "nice to have".strikeback03 - Thursday, July 12, 2007 - link
My P965 board has eSATA through one of the JMicron controllers, support for this has been in the Linux kernels since 2.6.18. so eSATA works fine in my system (2.6.20 kernel), though it might depend more on support for the controller chip than eSATA in general.ninjit - Wednesday, July 11, 2007 - link
Quick question about burst speed.You showed that the enclosure had a much lower Burst speed than when the drive was mounted internally, which you attributed to ICY DOCK's controller only supporting the SATA 150 spec at the moment.
However I just looked at their website for more details, and they specificially mention SATA 300 speed support, and have their own HDTACH results to back it up.

Could it be a setting or cable issue that caused your tests to drop down to 150?
