Re: Ultra Fit USB 3.0: Excessive Heat

@electronicsguy: As mentioned earlier, the temperature was measured with Infrared Thermometer which has 1.5'C accuracy tolerance.

Re: Ultra Fit USB 3.0: Excessive Heat

"well one person doesn't mean anything." This statement also includes yourself Electronicsguy. Obviously there are lots of people that have Ultra Fits that are not functioning properly. I don't have a digital thermometer to measure mine but as I stated when writing or formatting I can only touch it for 2 sec so it must be at least around 70 deg. Also the write speeds fall below 23MB/s so this is not functioning properly and is defective. These all should be recalled if they are running above 45c. No wonder Sandisk drives are some of the cheapest drives on the market. The only flash cards & drives that I have ever had fail/problems with are Sandisk. Anything Lexar I have ever got have been flawless and I will to continue buy Lexar instead of Sandisk.

Re: Ultra Fit USB 3.0: Excessive Heat

yes ofcourse it does. but if there was a design fault, it would have been recalled. people are only complaining because its get much hotter than bigger (normal sized) usb drives. speeds fall and vary even with normal usb drives. that's not a fault by itself.

Yes because manufactures are ALWAYS forthcoming when it comes to product recalls no matter how much money it cost them Smiley Very Happy. How about VW diesel cars of today? If manufactures can get away by ignoring the problem and hope a government agency doesn't find them out they will.

Re: Ultra Fit USB 3.0: Excessive Heat

Yes and the only people who write on forums are ones with a complaint. the others don't write. Is there any specific problem you have with the ultrafit other than heat or varying speeds?

Re: Ultra Fit USB 3.0: Excessive Heat

@electronicsguy: I believe it is not true that only people who write in forum are the ones with complaint. Many others out there may have similar problem but there are many reasons why they do not write in forum, such as:

 

1. They feel their problem has been well represented by other posters, hence once there is solution from manufacturer, their faulty device will entitle for the solution too. Why post so many posts while they indeed the same subject?

 

2. They may not aware of where to complaint about their problem.

 

3. They would rather let go the $$$ rather than spend time to complaint.

 

4. They may not aware of the risks of the excessive heat generated by the device.

 

5. They may not aware of their rights as a customer, especially those in countries where customer rights protection is weak.

 

etc...

Re: Ultra Fit USB 3.0: Excessive Heat

Write speeds do not exceed 23MB/s,Smiley Frustrated have tested using 2 different softwares. Any USB3.0 Lexar is capable of that. I'm just keeping this drive as a backup copy of my Lexar and keep on my keychain, that way I'm not really using it. In future I'll stick to Lexar or Patriot flash drives.

I'm afraid your argument doesn't hold water. Look at the specs from the manufacturers and compare apples to apples. Lets take the Lexar small profile USB 3.0 as you claim. This is the official page: lexar

 

You can clearly see: 

16GB in orange (up to 150MB/s read, 20MB/s write)
32GB in blue (up to 150MB/s read, 30MB/s write)
64GB in teal (up to 150MB/s read, 45MB/s write)

 

So what exactly are you complaining about when you're getting 23M/s write speeds? (Also remember the 23MB/s you measured is real world speed and the speeds quoted above ar "ideal" speeds which are not necessarily achieved)

 

Now if you compare this speed to lets say the large profile lexar one (like jumpdrive p20) which has write speeds of 80MB/s or more, then it's not a correct comparison since that one is a large profile (hence more heat loss, so can be run at higher speeds, more channels on board, etc). But I don't see what exactly you're tearing your hair about for a small profile USB drive with similar speeds as the competitor.

Re: Ultra Fit USB 3.0: Excessive Heat

@electronicsguy: wouldn't it be more suitable to compare with Lexar S45 (http://www.lexar.com/jumpdrives45?category=207) instead of S73 which is of bigger profile?

Re: Ultra Fit USB 3.0: Excessive Heat

ok. compare with that. similar speeds (all theoretical there, practical will be lower. in any case range is from 20-45 MB/s)
