Dell Inspiron 14R/15R/17R Turbo Laptop Thread

Zeon

Right off the assembly line
Can any one show screen shot of dell inspiron 15r HD 1366x768 Screen. I want to see how Hd 1366x768 resolution looks on 15 inch screen. Show me the pictures of desktop and open the browser with yahoo website.
Then I will decide between these two
17 version with HD Display 1366x768
i5 version with FULL HD Display 1920x1080

Are inspiron laptops cheaper in stores as compared to online price. Has anyone checked?

what stores are you talking about???
if it's local stores or dealers, yes they sell cheaper, but if you are talking about the DELL store, they sell at the same online price...

How much speed u guys are getting from usb 3.0, i am getting only 7-9mbps :(

i think you are using windows 7 right??
is this speed is on all of the ports or some specific ports, have you installed the latest USB drivers by intel???
i get ~50MBps on left side ports, as right side one's don't work on win8 drivers, but that's win8 bug, your's should be resolved by the latest drivers here...
Also make sure to format in NTFS...

^ Thats too low. :O I get 70-85 mbps on average. Lowest is around 35mbps(hapened once when I was copying 230gb at once). :|

i don't get that, but was getting 60-70MBps on the Ubuntu 12.10 livecd, i think Win8 USB drivers are unstable, and lots of people are having different problems with win8 USB3.0 drivers, like slow speed, drive unmounting etc..

Yea i am using win7, I just checked with the same soft tht u are using and i am getting results as 1.jpg

but while transferring data from my sony 8gb pendrive or via my mobile usb transfer , i am getting only 7-9mbps max for 4-6gb transferring...is it problem tht i am using a usb 2.0 device... idk how to check tht..?

firstly, the image you posted is of C:, not of the USB device you are using..
And secondly, you are saying these speeds for USB 2.0 pen drive??? :facepalm:
To check, see if the USB jack of pen drive is blue inside or not, if it's blue it's USB 3.0, else it's USB 2.0, and it's the normal speed for pen drives with USB 2.0, even USB 3.0 pen drives reach ~20MBps AFAIK..
To check USB 3.0 transfer speeds, try with a USB 3.0 HDD..

Okzz... when i try to transfer 5.5gb from one of my local disk to another, it is taking abt 4 minutes and in the mean while i am trying to open mozilla , it was not opening and got opened and gets hanged... when the transfer gets finished everything seems to be perfect... y is tht ?

that's because of i7 3rd gen... :wink:
just kidding, it's because of the "bottlenecked" 5400rpm HDD under the lappy, as transfer of files require heavy read and write cycles, 5400rpm drives are easily bottlenecked by this operation, opening firefox or any other application requires reading from disk and loading it into main memory, as reading speed and all the seeking time is already used by file transfer, therefore application seems to be opening slow or frozen, until it's completely loaded in the main memory...
SSD's don't have this problem as they don't have to move any mechanical head to simultaneously reach to any fragment on HDD, they just open it from the cell location, so this problem can only be removed by using a SSD..

5400rpm HDDs are not that slow as you're reflecting them to be. The problem could be due to any minor reason, background process, mozilla problem, file sector corrupt, or even HDD bottleneck in this specific case (when some other program which is not mentioned, is also eating disk bandwidth).

check this out ratul, i gt it when i am transferring data frm mobile via usb to hard disk....:( View attachment 8150

Its fine, the speed mostly depends on the quality of cable OEM provided you. Chinese cables give 1-2MB/s while cables of some good devices such as ext HDDs or some PMPs give up to 30MB/s.

yes, transferring from mobile via USB depends on the USB cable, it seems ok speed to me..

yes, they are not slow, but bottlenecking does'nt only mean speed..
it's not only 5400rpm drives, but most of the mechanical drives out there, i have 7200rpm drive on my desktop, and that too suffers from same lags...
it's because of whenever any data is to be fetched from mechanical drive, the head have to reach certain tracks and sectors on disk, and then read out the fragments of the files, as transfer process requires a large read and write cycles, therefore almost all heads of the HDD are used by it, and when you open any application, the head simultaneously try to fetch the application files, as well as handling transfer processes resulting in the lags, thus mechanical drives are bottlenecks on these systems..
SSD's don't have any moving parts, they just need to send a signal to specified cell location, and file is read from there, that's what i meant to say, not that 5400rpm's are slow.. :wink:
