Reviews - Tsunami D-25 USB 3.0 2.5in enclosure review - perfect for SSDs

[HEXUS]

Got a motherboard with USB 3.0 ports? You may want this enclosure. Read on to see why.

this would be good even for spinning-rust disks.

a 7200rpm drive would transfer at least twice as fast in this enclosure, purely because of the limitations of USB2.

Exactly. The fact that the Freecom mechanical drive was not even tested on USB 3 to measure the difference (if any) is disappointing.

The fact that the Freecom mechanical drive was not even tested on USB 3 ... is disappointing.

How exactly do you propose that Hexus test a native USB 2.0 portable hard drive on USB 3? Rewire the connector themselves?

What's disappointing (although perhaps understandable given the time limitations that bind most reviews) is that the caddy wasn't tested with a 2.5" mechnical drive, as that is probably where it would be most use. You could easily add a 320GB 5400rpm drive to this for a total cost of < £50 and get a very fast, relatively cheap portable storage.

Any chance of an update to the tests in the near future?

USB3 should be able to power a 7200rpm 2.5" drive, love to see if it can, and what the resulting performance is like..........

[Tarinder]

I've listened to what you have to say.

You want a 2.5in, 7,200rpm hard-drive tested on this caddy in USB 3.0 and USB 2.0 modes? You got it, but it will have to wait until tomorrow afternoon. Significant time pressure for launches next week

[R3MF]

awesome, i'd love to know whether USB3 has the juice to push a 7200rpm laptop drive without external power.

many thanks.

[Tarinder]

Yup, it does.

Here's how a Samsung 160GB, 7,200rpm performs on the best-case scenario sequential test:



Will update the full review tomorrow.

nice, i am guessing that is about double what is typical for a 'fast' USB2 drive.....?

probably closer to 100MB/s on a newer drive!

thank you

More than double: USB 2.0 bottlenecks at about 33MB/s read. Interestingly, it's a little behind the 64GB USB flash drive in reading, but a little ahead in writing. I will be very interested to see the real world results

Thanks Tarinder, really appreciate the responsiveness, and I look forward to the updated review

yes that is from similar enclosure. Twice as fast as my old 250Gb sata 2 disks


agrh I need at least 5 posts to link the pics...

Forgot to add that it can be powered from some usb 2.0 and tv usb ports. This makes all flash sticks a bit useless unless you have small pockets^^

Review is updated with the freshly-formatted Samsung HM161JJ in the Tsunami enclosure - run in both USB 3.0 and 2.0 modes.

[R3MF]

cheers Tarinder

[Jedibeeftrix]

fantastic.

the 8GB sequential read speed is what sells it for me.

using a modern high-speed 2.5" spindle drive i can well see that hitting 100MB/s, three times the speed that USB2 will permit.

that reduces my backup times from 9 hours to 3 on a terrabyte container.

for £16!

[scaryjim]

Wooo! Once again Tarinder, above and beyond the call of duty. Much appreciated

And having read the review again, I'm glad it was updated. We often move large data files (> 2GB) around at work, and being able to more than halve the time they take to copy would be a huge advantage: might be time to start pushing for some USB 3 expansion cards
