Bests & Worsts Reviews from Amazon

I highly recommend this Sandisk Extreme 64GB flash drive because : (1)Its maximum read speed, 200 MB/sec is the fastest of all USB 3.0 or USB 2 flash drives tested including more expensive Lexar Triton, Verbatim V3 etc. Its 185 Mb/s is top 5 in writes behind Triton etc. This saves you a lot of time when copying or reading files. This makes a huge difference if you are waiting at your computer for the copying to finish. (2)It uses USB 3.0 and can be up to 10 times faster in reads and writes than the fastest USB 2 flash drives if inserted in "USB 3.0 port". The speed gain is much less if inserted in USB 2 port. The speed can be verified with a free software called atto, downloaded from the internet. (3)It is like carrying almost the fastest 10000 rpm hard drive in your pocket, is more reliable with no moving parts, is smaller 2.79 inch x 0.84 x 0.45 and uses much less electricity. Its maximum reads 200 MB/sec are faster than the maximum reads or writes 133 MB/sec of the fastest 7200rpm SATA 6 GB/s hard drive 1 TB HGST Travelstar 7K1000. But slower than the maximum reads and writes, 209 MB/s of Western Digital VelociRaptor WD1000DHTZ hard drive(1 TB, 10,000 rpm, SATA 6 Gbit/s). The results are from tomshardware. Its speeds are much slower than solid state drives. SanDisk Extreme SSD 240 GB has 550MB/sec reads, 520MB/sec writes. (3)It comes installed with 128-bit AES encryption and password software, like Verbatim, to protect your data which is stored in a "vault" from unauthorized access. You can also store non-sensitive data on the drive outside the vault. Warning : My Norton Internet Security software rates the RunSanDiskSecureAccess_Win.exe, the software bundled with the drive ..............unstable. This program crashed in Windows 8 while I was using it to add files to the "vault", causing all my files to be deleted. There are ..............many reports of crashes on the internet. I tried 6 different undelete software like Pandora, SanDisk RescuePRO, etc, the best one is ..............Recuva using deep scan. I recommend using a more reliable and stable encryption software, not from Sandisk. (4)I store sensitive data on my flash drive like bank statements, passwords, scanned receipts , insurance policies, etc on my flash drive, but not on my computer, to protect from fire, theft, damage, unauthorized access, etc. The unauthorized access is critical if you lose your flash drive. I tie two 50-pound-strength translucent fishing lines to the flash drive to hang around my neck. (5)Up to 2GB of its files can be backed up onto a secure online server on YuuWaa "for free". This provides an extra backup in case you lose your flash drive. (5)Lifetime warranty, same as Verbatim, is much longer than the warranty for Kingston (5-year), PNY (1-year) and other flash drives. (6) To copy files 5 GB or larger onto this flash drive, re-format the drive in Ex-FAT. Ex-FAT also allow faster reads and writes than FAT16, FAT32, NTFS. Make sure the computer you are copying files from has the Windows driver installed to read the Ex-FAT format. Also make a copy of all the software on the flash drive because formatting writes over all the data. (7) $70 charged by Amazon is much less than the $100 charged by Staples, Fry's Electronics, etc. It takes time to research these information.
