That’s 167 MB/s sequential write—pretty cool. Since this is on Windows 7, there’s no UASP support, which should improve performance even more. Be the first to like. Like Unlike
I ran these on my (8GB RAM) Sandy Bridge Core i7-2600K (not overclocked) H67 machine. I compared a newly bought USB 3.0 16 GB drive to an internal Kingston SATA and a previously purchased 8GB USB 3.0. I also compare the USB 3.0 drives to their performance with USB 2.0 port speeds. Be the first […]
Testing these drives: Newegg.com – Kingston DataTraveler 101 Gen 2 4GB USB 2.0 Flash Drive (Cyan) Model DT101G2/4GBZ I got them free with some RAM. Here are the results:
