Just a reminder that this drive gets very hot during operation and will slow down as a result, appears to perform fine during benchmarks but will not be able to fully transfer large files as it grinds to a halt due to heat. Decent for storing large amounts of small files like songs an videos over time, but don't expect to be able to get it all onto or off the device in one go.
worth getting it just to leave in a laptop for extra storage space? (MBP)
Also be aware that you may damage usb ports of left in for too long.
Is that particular to this flash drive or a general rule/problem?
USB port damage? I don't think so. If you can find actual cases of this happening, please give a link. I've seen a lot of posts theorizing about possible damage, but none listing actual damage.
Computer motherboards are soldered with reflow soldering - so the entire board, and all the parts on it (including USB sockets) gets heated up to over 200 degrees centigrade, and that doesn't damage the USB ports.
I agree, while it gets very hot to touch, it's not nearly hot enough to cause damage to circuitry. Much more likely it warps plastic casing in bargain basement laptops.
This is from what I have read of other people's experiences in similar threads.
I myself have this usb and have noticed the abnormal heating. I am a bit too worried about it damaging my usb port in my macbook to leave it in to long to test it though.
I have this USB, and found that it got hot only while in my laptop, not in my desktop. I now use a short USB3 extension cable, and it doesn't get nearly as hot, so much of the heat was being contributed by the laptop itself.
I've never had mine so hot that I couldn't hold it continuously, albeit with a little discomfort. That puts it in the 40-50 degrees centigrade range. Above 50 and you would drop it within a second or two, skin scalding starts at about 53 degrees. The lowest temperature spec for electronics is 70 degrees, so the electronics will be fine.
In Queensland, the Australian standard for car burglar alarms specifies that they must withstand 70 degrees continuous, because that's how hot it gets inside parked cars. I imagine that any laptop would have at least that rating for its plasticwork, or there would be a lot of returns!
I leave it constantly plugged into my macbook air and I've never had an issue with either the 16gb or the 64gb.
Try transferring files larger than 10GB. I get around 50 MB/s for the first 10 seconds, then it drops down to 15MB/s, and iirc when I was transffering a 25GB file it would drop down to 0.2MB/s after about 18GB and the transfer would essentially never finish. I don't know the details but it feels like temperature throttling to me, and since the device has no real efficient way to dissipate heat it will simply grind to a half when it gets to a certain temperature.
Fine for a movie or a few dozen songs, doesn't work when you try to get it all off the drive at the same time or transferring a big disk image or something.
Interesting. Perhaps the aluminium case of the macbook air helps it cool.
Do USB drives even have temperature monitoring? And would the OS slow down copying if it did? And would the Drive slow down if it got a bit hot in 10 seconds?
I doubt it.
Plus it would not get excessively hot in 10 seconds.
@SamR: SSD's do this kind of thing but I doubt the circuitry exists in tiny devices like this one. That's actually even worse though, because it means the throttling is physical rather than software, the device would be getting too hot to physically function. It doesn't seem to cause long-term damage as it works fine once unplugged and cooled down.
It gets pretty hot after 10 seconds, very hot after a minute or two of continuous file transfer. Don't underestimate how quickly metal can heat up when you run a current through it.
Yeah im getting a little sick of the constant 'this drive gets hot' comments. Maybe some do, mine definitely doesnt. Full 50 MB/s speed for huge files, even when transferring 20~ GB of ISO files (700mb - 3GB a piece).
Electronics can and do get hot, to some extent that is expected, a faster drive will switch more often. There could just be some duds but my experience has been great. If size isn't a concern then the PNY Turbo seems to stay ice cool and are solid.
Heat is a problem noted in many reviews, the slow down has been reported elsewhere and I've personally experienced it. Maybe some don't have problems, but any buyer should be aware that many have reported issues.
Any chance you could get the 128GB down to around $45 delivered to compete with Amazon?
I will not trust shoppingSquare ever, i order one thing which was never delivered, and excuses were it was sent but no one received and returned back which they could not confirm where was it acutally sent because it never came to me. Had to wait one day for every response.
DONT TRUST THEM.
I will wait for PCByte or Shoppingexpress to privide same/better deal.
Thanks for the heads up
has anyone tried using this to bootcamp windows on it for mac? i currently have a bootcamp windows on a 2.5" external ssd, but a USB would be ideal for being this small, can leave it plugged in.
Last I checked windows (whether EFI or MBR cannot be installed itself from a USB, has this changed?
i used Windows2Go to make it work.
I wouldn't recommend it, running an OS on a usb tack like this will wear it out very quickly, especially given the temperature this tends to operate at. If you have a good backup system set up and don't mind your Windows OS going kaput then it's certainly possible, but be aware that there's good risk 2 years down the line where the device just dies.
thanks for the feedback, might go the SD card way then
Do SD cards more reliable flash chips?
Hey Rep, still waiting for the 128gb microsd deal you told us you were working on.
