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.
