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

Got it from this slick deal. It actually performs better (on the reads) than advertised (advertised as 120MB/s), and slightly better on the writes (advertised as 70 MB/s). Update Oct 19 I ran some dd tests […]
Looks basically like that other Corsair I bought a month ago. I basically bought another one so I can set up my FreeBSD root as a mirror of two 16 GB USB drives that are relatively fast for USB (even in a USB 2.0 port). This is in a USB 3.0 port:

I’ve been reading up on using a USB flash drive as an L2ARC for ZFS. Some reason that since the bandwidth of USB is much lower than SATA. However, others reason that since the USB flash drive has no seek time, it will speed up non-sequential reads, which is what the L2ARC is there for. […]
