Enclosure and HDD Compatability

[neywherkx]

Hello,

Several months ago I was in need of an external storage solution that was mobile and had high performance so I purchased these:

Now I'm in need of a second external HDD and I just realized looking through the product descriptions that the enclosure I purchased only supports SATA I/II speeds.

I was wondering if anyone could let me know; what am I missing out in terms of performance using a SATA III HDD with an enclosure that supports SATA I/II speeds?

Also, are there any enclosure's that any of you would recommend? I'm interested in both single and multi bay options.

Thanks

Not having worked with that Rosewill RX-358 USBEHD enclosure I can't comment directly on its performance relative to speed considerations between installed SATA II & SATA III disks in that device.

However, we have worked with a number of USBEHD enclosures in the past whose specs indicated support only up to SATA II disks. In a number of comparisons we made with various other USBEHD enclosures that supported SATA III disks (so said their specs), we could find no significant differences in data transfer between the various models when either SATA II or SATA III disks were installed in the USB devices. And even when we cloned disks to either USBEHD device (as we frequently do), we found very little (if any) difference in data transfer as I recall.

(I should add that whatever experience we had in this area was with HDDs - not SSDs. I don't recall working with any SSD in a USBEHD that (presumably) did not support SATA III.)

Lately we've been working with an ORICO 6518US3 USBEHD enclosure. We have three of them and they've all performed admirably. We don't work with docking stations any more - they're a bit too bulky for our taste. But many users prefer them.
