Oxford 911-based enclosures have various speeds

[Bfavre444]

I've had a baffling question that I just can't seem to figure out. Why is that there's so much variation in transfer speeds between HDD enclosures with Oxford 911? Shouldn't the performance of all Oxford 911-based enclosures be the same? For example, if one can do 35MB/s sustained, then all of them should do 35MB/s. It's the chipset that determines speed (harddrive being the same). Why can one enclosure can go so fast (35MB/s) while others can only do 23MB/s sustained and some can only have 11MB/s? After all, the enclosure is just a box, and the chipset is the brain.

I'm starting to wonder that too. My laptop drive seems to max out at about 16-20 MB/s on one Oxford 911 case, but consistently hits over 22 on another benching off the same empty partition.

The chipsets were the same, but the boards were different of course though. Not a huge difference, but I suspect it's real.

I've NEVER seen an 11 MB/s max Oxford 911 enclosure though. Is the drive fragmented?

I had a fellow Anandtech user do some benchmarks with this oxford 911 based enclosure and he gave me some results here. And average was 11MB/s and peak was 15MB/s.

I just got a Cutie 2.5" Oxford 911 case. Stuck a 60 GB Toshiba laptop drive in it, and again, I'm getting stuff in the 20 MB/s range.

Are you sure it's Oxford 911? Other chipsets would be more in the sub 20 MB/s range. eg. Indigita, Initio, etc.

Here is my review of the Cutie Oxford 911 enclosure.
