There is no indication that this is an SSD as you mentioned, it does not state the technology used, I have looked on their website and a few other places, SSD's just use multiple channels, for the most part (other than specialized equipment) uses the same technology, just more simultaneous read/writes, which in USB is limited to a maximum of 4 channels, and SSD's start at 8, so by definition it is NOT an SSD, it is a flash drive, but this is just mincing words.
My statement about Sandisk was merely stating that EVERY Sandisk flash drive or memory card for that matter, has been much much slower than the rated speeds, I would have 2 flash drives, USB 2.0, plug them into the same port, transfer the same file and the Sandisk would take 4-10 times as long, believe my I did my research at the time, I sent back a Sandisk flash drive 3 times to Sandisk for free replacements because I thought they were damaged (their rates were actually slightly higher rated than the Transcend I was using for comparison), formatted in multiple file formats (NTFS, FAT32, exFAT) all were extremely slow. I have heard mediocre reviews of all their SSD's when I was looking for one, citing slower than rated transfers, write cliff effects, and occasional not accepting SATA III when they were rated for it, the occasional raving review of someone going from a SATA I drive to SSD on SATA III, but you discount those for any brand.
I think the main thing is you will never need anything that fast, unless you plan on gaming from the flash drive, even then, that's not good for the flash drive, you can transfer the entire contents of the flash drive in less than 2 minutes, why spend extra? (you can get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820220653&IsVirtualParent=1 one and be done in less than 4 for almost 10 dollars less)
As far as the Corsair that I was referring to I do not know the transfer rate ratings that it had on it, but I know that when transferring things I saw upwards or 120MB/s for almost 10 seconds when transferring information onto it, that was coming from a 7200 RPM SATA III drive, transferring an 8 GB file.
If someone were buying one that was 64, 128, or more then yes it would be worth spending a little extra on a faster one, but at 16? save your money I would say.
I was not trying to argue with you, just merely stating my experience and opinion.
