Sandisk Ultra USB USB 3.0 32 GB Pen Drive

Actual capacity - 14.7 GB Speed on usb 3.0 Write - 45 Mbps Read - 95 Mbps Speed on USB 2.0 Write - 26.5 Mbps Read - 32.4 Mbps I have got this pd in 300/- under an student offer.

Should you buy this? Well, considering how closely its priced to other 32 GB pen drives, the decision is a no-brainer.nWhile it isnt a scorcher like the SanDisk Extreme pen drive (you can find my review on Flipkart), it definitely has enough grunt to actually make it worth the very small premium.nDon't have a USB 3.0 port? Well it's still worth it. You are still guaranteed a certain level of performance.nnBuild quality is good. The pen drive is fairly small and light. The housing is plastic with a sliding USB connector at one end and a gap at the other to attach a lanyard.nThe sliding mechanism feels good and has a locking mechanism. The USB connector is coloured blue to indicate USB 3.0 compatibility.nThe plastic housing has a matte finish on the sides and bottom and feels quite durable. The feel however does not come close to the awesome soft-touch feel of the SanDisk extreme.nThe top of the housing is glossy plastic to accentuate the SanDisk logo and add a bit of shine to the overall look.nnnPerformance summary:n- Amazing read speeds for few large files. You want a USB 3.0 port to take advantage of the read speeds.n- Pretty good performance for many smaller files. Better than most in this price range.n- Write speeds for few large files is pretty average. Was expecting more here. You won't lose much with a USB 2.0 port here.nnnBenchmarks:nnCrystalDiskMark 3.0.2 x64n- Test - Read Speed - Write Speedn- Seq. - 142.9 MB/s - 28.32 MB/sn- 512K - 114.3 MB/s - 0.454 MB/sn- 4K - 5.074 MB/s - 2.005 MB/sn- 4K QD32 - 4.126 MB/s - 1.717 MB/snDisappointing sequential write speeds. The 4K transfer speeds are pretty good though.nNote sure what is up with the 512K random write speeds. Some controller inefficiency maybe?nnSingle file copy; 3758 MB file on a RAM disk.n- Read - 29.4 seconds - 127.82 MB/sn- Write - 112.5 seconds - 33.40 MB/snRead speed were very consistent peaking to about 130 MB/s.nWrite speed started very slowly before settling in. The speeds fluctuated between 27 MB/s and 40 MB/s in a very regular pattern (graph looked like a sine wave :D). Peak speeds of 47 MB/s were observed.nnMultiple file copy; 1196 files over 8 folders totalling to 3825 MB on a RAM disk. The files consist of some ~5 MB photos taken on DSLR and some 1~2 MB photos taken on a phone.n- Read - 44.75 seconds - 85.47 MB/sn- Write - 139.56 seconds - 27.40 MB/snRead speeds were again very good, with very little fluctuation.nWrite speeds were strictly average. Nothing worth mentioning here.nnnConfiguration:nASRock Z87M Extreme4nCore i5 4670Kn2 x 4GB 1600 Mhz DDR3 RAMnWindows 8 64-bitnDataram RAMDisknThe motherboard software comes with a tool called XFastUSB which can increase the transfer speed for smaller file sizes. All tests were run with XFastUSB disabled.
