“USB Speeds Explained”:http://www.kingston.com/products/MKF_530_HS2_overview.pdf. Well, I’m finally getting one for Connie. Talk about a confusing market. There are basically three standards:
* USB 1.1. This is very slow. 1Mbps
* USB 2.0 Full-speed. This is 12Mbps
* USB 2.0 Hi-speed. This is 480Mbps
Many folks are saying just USB 2.0 and making you think they will go at 480Mbps. So watch out. There is about a $7 price difference. Kingston sells a USB 2.0 256MB drive for about $67 for USB 2.0 and $74 for USB 2.0 high-speed. Kingstons are nice in that they have a 5 year warranty (of course whos going to not lose their flash drive in 5 minutes
All the drives are plus or minus $1 so right now the sweet spot pricing is (according to newegg.com):
| Capacity | Price | $/MB |
| 128MB | $45 | $0.35 |
| 256MB | $74 | $0.29 |
| 512MB | $168 | $0.33 |
| 1GB | $250 | $0.25 |
So on a cost per bit basis, the 256MB and the 1GB (surprisingly are actually cheaper. Part of that is because Kingston has a great price on 1GB right now. Other vendors are at $300.
There is also a claim that actual transfer speeds can vary. I’m confused by that, Perhaps because of flash speed or more likely interface design. There are certain USB 2.0 controllers that can’t hit 480Mbps I’ve read.
Net, net, the Kingston isn’t a bad choice and it has a key ring holder so you have a chance of not losing it
