COVERED HERE: Actual storage space, Heating, Mobile Phones, Tight Fitting on mobile phones, Speed, Formatting File System, Value for Money, Free App, Company, Brand, Seller. About Company, Product & Seller: 1. SanDisk Ultra is a brand of Western Digital which is the same company that sells external hard-disk storage devices under the brand WD Elements and WD Portable. 2. About 3 to 5 years ago, WD Elements & Portable drives of 2TB and 4TB were priced Rs. 1200 less than current day prices. They were sold by Cloudtail Seller on Amazon. 3. Now SanDisk and WD drives are sold by Appario Retail Seller on Amazon. 4. For best prices on SanDisk and WD products in India, the current seller has the lowest prices for authentic brand new products. 5. Reason for higher prices for same brand's same capacity storage devices may be various - such as import duties, taxes, manufacturing costs, higher demand for the brand, etc. REVIEW: SanDisk Ultra Dual 64GB USB 3.0 OTG Pen Drive (Gold): 1. STORAGE SPACE: Just as in external hard-disk drives, the actual usable storage space will be less than what is mentioned on the product. 2. SAME AS OTHERS: For the 64GB pen drive, actual storage space available is 57.2GB. This is normal and not some fraud or fake advertisement. This is because it has FAT32 File System. Also, the device uses some space for its functionality and use. - In Linux OS laptop the available storage space on this FAT32 pen drive is shown to be 61.5GB. So that's 4GB more than what Windows OS calculates using their NTFS File System. 3. HEATING: Even with just 10 minutes of use, you can touch and feel that the metal part of the pen drive is getting heated. But the performance of the drive has not got affected by the heat. This heating does not happen in WD external hard-disks and seems to be unique to small pen drives of various brands. 4. MOBILE PHONES: The pen drive works with Android OS of Mi phones such as Redmi Note running Android including old Android Version 9 as well. 5. TOO TIGHT FOR PHONES: The pen drive is a tight fit on mobile phones & tablets - so be careful when pulling it out so as to not damage your phone - because this is also the charging point for your phone. If you feel that your phone is too tight for this pen drive, then it is best not to use it for phone data storage management. 6. VALUE FOR MONEY: Even if you don't use this pen drive for mobile phone - it is still the best price for a 64 GB pen drive with a USB 3.0 backward compatible with older USB ports on older laptops and computers. 7. SPEED: The Speed is extremely good for Windows OS laptop, Linux OS laptop and Android Mobile Phones. 8. FILE SYSTEM FORMATTING THE PEN DRIVE: Unless you are sure you won't use your pen drive on a particular device, don't format the pen drive to change its FAT32 File System. But For Example, If you have decided that you won't use it on mobile phones or tablets because the fitting is too tight and you don't want to risk damage to this point which is primarily used for charging - then go ahead and format the pen drive for your laptop. - With NTFS formatting you will see an increase in available storage space in your pen drive. - With your Linux system's file format, you will have better storage space than any Windows File System. - BEWARE that if the pen drive has NTFS File System then it won't work with mobile phones, tablets, laptops which don't have Windows Operating System. Same way, if you format the pen drive for Linux OS File System, it won't be recognised on Windows laptops, Android phones, tablets, etc. - if like most people you will be using this pen drive on laptops or other devices of friends or co-workers, then leave the existing FAT32 File System as it is. 9. FREE APP: Memory Zone App for Android is bundled free in this pen drive. It is easy to install and doesn't take any Phone Permissions other than Storage Access. It is very useful App with easy user-interface. App takes 64MB storage space on Android Phones. - Features include: cleaning Junk Files that you may not otherwise know through your phone's File Manager App. Enable or Disable Automatic Backup to your pen drive. Add Cloud Storage such as Google Drive or Microsoft One Drive and Add MicroSD card storage to manage all your files from just one Memory Zone App. Restore Backup. Copy, Move, Delete, files as well as clean up WhatsApp related files. See available storage space on your phone. See data sorted into photos, videos, music, documents. 10. BEWARE - Users of Memory Zone App should know that they agree to Terms of Use which include that if some government agency requests the company for information against piracy - such as illegal copy, storage, distribution of Movies, Music, Software, Books, etc as per DMCA copyright laws then the Company will provide the user's data to the government investigating agency to protect the intellectual property of content owners. OVERALL - best product in the market, at best price in Indian market, with features not offered by other companies for similar specs.

Product quality better

It's a good pendrive considering its price and ready to go on pc as well as smartphone with its usb/otg port. But don't like its body as it is too small to handle and it doesn't have any fixing point (i mean which will fix it when usb will be driven out or when micro usb will be driven out), as it results in slipping when you try to put the usb socket of pd in your laptop it starts sliding backwards or when you try to connect it with your phone same happens, it is little irritating if you get me properly. Build quality is decent and yes it gets heated up as its normal (only the aluminium frame). And the speed is good, in my case, while transferring from pc to it the speed is 18 mbps on average (depends on configuration of your pc) and from transferring to pc from it the speed is 88-90 mbps on average and using it with phone I've transferred a 950 mb movie from it to my phone (redmi note 4) and it took 47 seconds to copy it which means an average speed of 20 mbps. I've uploaded all these photos you can see from it. Final verdict is that only available best option in this price range is this product (i mean a pd with otg support) so you can go for it as your requirements and also verify this product by reading most of reviews. Thankyou For Reading. :::::Recent Update::::: Everything is working excellent!! And today i transferred 1.34 GB movie on pd through my new phone honor 8 pro and it took 39 sec's to copy meaning an average transfer speed of 35 Mbps which is great in my opinion, you can check it by the sample I've uploaded!! Thankyou Amazon for such a great deal... MAJOR UPDATE (after 2 years):::- It working flawlessly, and i still support my review as stated above AND ONE MAJOR THING WORTH MENTIONING IS THAT NOW IN NEWER MODELS ( I'VE BOUGHT IT LOCALLY, BECAUSE OF URGENCY) THEY STARTED IMPLEMENTING SOME SORT OF FIXATOR WHICH FIXES THE INNER DRIVE WHEN SLIDED OUT AND PREVENTS IT FROM SLIDING BACKWARDS WHEN FULLY OPENED, SO IT'S GREAT THAT THEY HAVE SOLVED THIS SMALL PROBLEM... YOU CAN ABSOLUTELY BUY THIS PENDRIVE, I'M TOTALLY SATISFIED WITH IT'S PERFORMANCE.

This is a Good product and has a good storage easy to use highly portable. Also connect with mobile good

➖➖➖➖➖➖➖➖➖➖ Price: 699 Seller: Appario Retail Private Ltd ➖➖➖➖➖➖➖➖➖➖ Bought it in a flash deal. The first one I ordered had some write protection error, despite trying everything to fix the error nothing worked. So I placed a replacement request. I owned the previous generation of this OTG pen drive which was much better compared to this one. It had a good read and write speed but it stopped working one fine day. It was only 3 years old and was well within the warranty period. But the paranoid me didn't go for a replacement, thanks to the hoards of personal stuff inside that pen drive. Coming back to this pen drive, let me split into pros and cons: ➖➖➖➖➖➖➖➖➖➖ PROS: ➖➖➖➖➖➖➖➖➖➖ ✅ Cheap (almost same price) compared to other USB 2.0 pen drives. The pros end here. ➖➖➖➖➖➖➖➖➖➖ CONS: ➖➖➖➖➖➖➖➖➖➖ ❌Slow Writing Speed: Although the company claims it is a USB 3.0 pen drive it's not a USB 3.0 per se. It has a very low average writing speed of 19.65 MB/s. This is almost double the speed of old gen USB 2.0 Pend Drives. But it's nowhere near the USB 3.0 standard. I'm not telling it's bad but it's good neither. 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 ❌Average Reading Speed: The writing speed is pretty average. The benchmark test gave a read speed of 36.98 MB/s, which again is better compared to USB 2.0 standards but not great when it comes to USB 3.0 standards. 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 ❌Design: Design needs some getting used to. If you try to plug in the one side to the port the other side will slide away. Definitely not a deal breaker but quite annoying initially. You will get used to it pretty soon. Previous gen SanDisk was much better in this regard. 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 ❌Heat: This product heats up pretty fast. Again not a deal breaker but compared to other pen drives the temperature is on the higher side. 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 ❌Fluctuating write speed: In the benchmarking, it gave a pretty steady 19 MB/s but in the real-world scenario, depending on the type of file, there is a tendency to fluctuate the speed to the extreme extends. I've seen some reviews stating similar issues. ➖➖➖➖➖➖➖➖➖➖ For the price I bought (699), I find it pretty decent. But I just don't like the marketing gimmick they use to lure customers in, by promising speeds which is far far more than the actual speed. It doesn't have a huge edge over normal USB 2.0 pen drives. Of course, it's is still better than old gen USB 2.0 pen drives. I've done a benchmarking both on USB 2.0 and 3.0 ports, the speed I got from both the ports were pretty much same( Pics attached- USB 3.0- Write:19.65 MB/s Read:37.98 MB/ s: USB 2.0- Write:16.49 MB/s Read:32.38 MB/s). This is why I've to conclude that this is not an actual USB 3.0 pen drive. ➖➖➖➖➖➖➖➖➖➖ We have already covered the pros and cons now let's conclude: If you are not so much worried about speed and need a decent otg pen drive you can go for this. I would suggest you wait for flash deals. Afterall, we don't have a lot of options when it comes to OTG pen drives. Moreover, when you plug into your android phone it won't make a huge difference in write and read speed be it USB 2 or 3. It is still. Better than USB 2.0 which will cost you the same and in certain cases more than this. If you are so very keen on high performance then you have to look elsewhere. My suggestion would be to invest in a good, proper USB 3.0 pen drive and use an OTG cable. I'd give this product a 3/5. I'm giving 3 specifically because of the false promises the company gave and the heating issue. This product is neither great nor bad. In the end we get what we pay for. ➖➖➖➖➖➖➖➖➖➖ PS: Keep your USB 3.0 drivers updated. Keep in mind that it's non-returnable you can only replace it. Read other reviews as well especially 3 stars and 2 stars reviews. ➖➖➖➖➖➖➖➖➖➖ I hope this will help you make a decision. Thanks for your time. Cheers...
