Pros: Runs SLI well, default fan speed settings are quiet, solid price/performance.
Other Thoughts: I used one of these for months and was very happy with my 1920x1200 performance. But I did the 4770K system build and snagged a 2560x1600 monitor and, well... I debated doing a GTX780, but instead just bought a second identical PNY GTX660. Zip zoom zing, the SLI configuration is fast and keeps my 4M pixels updating speedily. Faster than a 770 and it'll definitely give a 780 a run for its money.
The default fan settings do seem to aim for quiet over cool, which is fine with me. The hotter of the two cards will hit 80C when things are busy. If I tweak the fan settings with MSI Afterburner I can shave 10C off the temps easily, at the cost of a few dB of noise. I think 80C is ok (NVIDIA says 97C is the max allowed) so I'll take quiet.
Pros: It works well.
Cons: Performance, at least for me, is lacking. On USB 3.0 I was getting only about 42MB/sec. That's barely better than USB 2 speeds. I only have one machine that has USB 3.0 ports, so I couldn't try another host, but I have other USB 3.0 stuff I've used on that machine and it can do >100MB/sec. I finally just cracked open the case on the drive enclosure (which I failed to do without fairly destroying the case) and put the drive on a SATA port. There I can sustain about 95MB/sec. This is still quite slow compared to other 3T and 4T drives I have, but that's not too surprising since this HGST is specifically a low-power, slow RPM drive.
Other Thoughts: I'm using the drive as an offline backup for my NAS. Now and then I slip the drive into an external SATA base, mount it, run rsync, and then pull it. It's working fine for that. 150MB/sec would be nicer, but 95MB/sec is usable. 42MB/sec... It takes 26 hours to write 4 TB at 42MBsec.
Just understand if you get this model it's not about performance.
Yo, HGST... If you're gonna give us a USB 3.0 drive, could you give us one that can beat USB 2 speeds?
This review is from: Mediasonic HF2-SU2S2 3.5" Black SATA I/II USB 2.0 & eSATA Pro Box 4 Bay Enclosure
Pros: I stuffed in 4*2TB green drives and it worked great with a Syba PEX40008 card. That card isn't a super performer anyway, being limited by one slow PCI-E channel, and the single 3Gbps connection to the drives didn't seem to hinder it.
Cons: When I put in 4*1.5T 7200 rpm Barracuda drives, it won't power on. As it goes through the boot sequence, when it fires up the Syba card and it goes to spin up the drives, the enclosure powers off. If I put in 2 1.5T and 2 2T drives it makes it up. And if I boot with one 1.5T drive and then add the other 1.5T drives one by one after the boot, it works. So it seriously feels like the 4 1.5T 7200 rpm drives pull too much power to all spin up at once.
Other Thoughts: I'll find this box completely usable. I can put a mix of high power and green drives in it and accomplish what I'm after. It'd be more convenient not to have to do so, but for the $80 I paid for the enclosure it's still a good deal.
I'd also like it better if it didn't use the stupid screw-on-front handles. Put springs in the front bezel to hold the drives in firmly, instead.
