Got it from this slick deal<\/a>. It actually performs better (on the reads) than advertised (advertised as 120MB\/s), and slightly better on the writes (advertised as 70 MB\/s).<\/p>\n
Update Oct 19<\/h3>\n
I ran some dd tests on FreeBSD to see what the sector size of this device is. Looks to be around 64kB:<\/p>\n

FreeBSD only allows a maximum fragment size of 32kB.<\/del> Update: I found that you can set a fragment size higher by setting the sector size using the -S option in newfs.<\/em> If I want to use this as a boot drive, I probably want to enable soft-updates. I’m not crazy about that, as I like to keep every write synchronous. But, the FreeBSD manual says that it’s basically safe–you might lose some data in a 30-second interval, but only if the system crashes–in which case, the time it takes to write to disk on this drive also becomes an issue. Will maybe try that.<\/p>\n
This post on FreeBSD on SSD’s<\/a> recommends soft updates, but more importantly, shows you how to get a swap file that uses TRIM.<\/p>\n
