Where the tinsy Corsair Flash Voyager Mini is only 35mm long before the retractable plug is extended, the new 64GB Voyager is a protracted 100mm from end to capped end. It's conspicuously longer than the original 8GB, 16GB and 32GB versions of the Voyager or Voyager GT. Figure in its 27g weight, and you can see it presents a weighty load for any USB port.
Just remember that wrapped up inside its thick rubber casing is 64GB of flash memory storage (60.2GB available after formatting). It's too easy to get complacent about our current storage options, but lest we forget, 64GB would have been a luxurious-sized hard drive for a complete PC only a handful of years ago. Today, we can now carry that amount of storage on a keyring.
There is a caveat to these huge capacities, though. Where NAND flash memory was once exclusively of the single-layer cell (SLC) variety, today we are seeing increasing use of multi-layer cell (MLC) technology. While this does raise capacities and help lower prices, MLS is also appreciably slower than SLC memory. So be prepared for longer transfer times, particuarly when writing to the Corsair Voyager 64GB USB stick.
In our tests using HDTach 3, we recorded read speeds of 24MB/s, just a little below the average we see of around 25-30MB/s. Write speeds were more disappointing, however, at only 7.5MB/s on HDTach's longer test using 32MB zones. And this figure fell to a plodding 5.4MB/s with 8MB zones. Random access time was 0.8ms, a good low number.
So while a huge headline capacity may be appealing, bear in mind that the time needed to fill this drive's tank to full, based on our lab test measurements, would be around three hours.
To check practice against the theory, we tried copying a 2GB folder of assorted files to the Corsair Voyager 64GB. The process took 11 minutes 30 seconds, suggesting that a full capacity transfer would take closer to six hours in the real world.
