Does the fact that these drives draw power from the USB decrease their performance? I'm concerned, however, in two regards: 1) Will this feature result in decreased performance of the drive vs. the same size, same rpm, same buffer sized drive which is...

1, yes. if you power a HD of the 5V USB, it will run at about 5200RPM like a laptop HD. This will slow down your transfer rate. 2. I don't believe this should slow down other USB devices more than normal. Only one device can be accessed at a time anyway,but It all happens so fast you wont notice. 3. Depending on Seagate, normally the enclosure should see it has 12V and not need any power from the USB. Unless your are hanging 40 USB devices off your PC, there should be no power issues with other devices.

sorry, I haven`t tested that. I will have a USB3 portable hd soon. I'll check it out.

MANUFACTURER RESPONSE: Thanks for asking!In a word, no- however as another respondent has noted this would require a little extra caution when handling the drives.Hope this helps!

I haven't noticed any decrease in performance between the powered 3.0 drive and the 2.0 flash drives I have plugged into this hub. They work at their rated speed for the most part. For the most part the computer's controller chip and the device controller work those issues out unless there bad programming involved

Hi,I bought this drive to replace drives in my network storage (that had standard computer drives). One thing I noticed was they were much quieter! The spec comparison on drives put them on the slower side which is why they're advertised as "network drives". This being said, I have not noticed any significant difference on speed in my network device...You would probably be ok..

My apologies for not get back to you sooner . I don't know about how fast the RPM's are on this drive. I think it would be based on thee fact of the speed transfer rate. I looked up info for the drive including the BUFFALO website but i did not find anything. Is a fast drive, good luck

I have an older Seagate External HD (1.5TB) and a few 3TB Western Digital HD. I have them hooked to my Window 7 desktop through the Anker USB 3.0 hub; so far I have no issues. When not accessing data on my external HD, the disks do spin down gracefully and go to "sleep"...so far I have not had any issues with this device...hope this helps...

Simple answer: Does this rumor apply to your typical USB flash drive? No. Same thing goes for the SSD.Don't go defragging the SSD, though. First, you don't need it because there are no moving parts and secondly, there is miniscule degradation with each (re)write. I do mean tiny, too. You'll be buying a new computer before you replace an SSD, unless you go around defragging every couple of days.

Given that there are conflicting answers to this question on Amazon, and I really wanted to know before purchasing a drive, I contacted Seagate. Here's their response: " Unfortunately, part of the information is not provided at all. The RPM of our Expansion drives are not a provided specification, meaning the unit can run from 5400 RPMs to 7200 RPMs. We have no way to know which is it. It is not a guaranteed specification." So, it's a crap shoot. And it matters.

I have 3 of these Sabrent drive enclosures and I populated two with 500GBs and one with 1TB. All three worked as I expected. BTW, I only tested them on USB 2.0 connections. I'm still waiting for my "GMYLE® ExpressCard 34mm to USB 3.0 Adapter (Dual Port)" to see if the USB 3.0 connection is any better. I currently do not have a machine with a "native" USB 3.0 interface. I have not tested these units using an SSD.

Ya know, I've just not tested that. I'm using mine with three Hitachi NAS drives. I'm pretty sure the consumption would vary by the drives. 7200 rpm drives will certainly draw more power than 5400 rpm drives. I'd suggest you email their tech department. They are very responsive I'm happy to report.

USB Drives don't have the capability to sleep, unless the unit turns itself off, it would be impossible to send the hardware signal to sleep the drive. They've mentioned the unit turns off but in my experience it turns off until you turn it back on again by pressing the button, it's not the "sleep until accessed" that you get with eSata/Sata drives.

WD says that greens will work and nothing else. I have a feeling that has to do with the lower power consumption. I have heard horror stories about green drives and WD software has said my drives have gone bad, but the drives read and write just fine. I love the raid setup and dont know why anyone else hasn't continued this setup at this price point ( I bought mine used for a little less than $100)

I run 4 of them right now with one slot empty in between them and it will run without a fan. However, these seem to dip to 1.4 GHash/s after awhile (even with a fan). Could be my USB hub. Seems fine if restarted.

I keep it just plugged in all the time regardless of what I do with the (desktop) computer. The drive seems to be performing well and I think I've had it more than a year. I'm using it for local file sync'ing. It's usb so you should not need to mount or unmount.

Yes and no. This depends on the power that is supplied by your laptop and the power requirement of the connected USB device. The power supplied by USBs vary from one laptop manufacturer to another. It really shouldn't but does. Thumb drives and mSATA enclosed hard drives really don't consume a lot of power. You could probably plug in 4 of these and have no problems. However, portable drives such as portable hard drives (regular or standard SSD) and CD/DVD/Blue-ray require a good amount of power. I've found that I have no choice but to use an external power supply if I plug in two of these. My laptop cannot provide enough power for even two of these types. One will consistently drop out.

I've had no issues with the speed of the unit. It really depends on the drives you use.
