I have the 120 Gb LaCie Rugged SSD (Thunderbolt and USB 3.0).
I noticed the same as the other users: USB 3.0 has faster read speeds compared to Thunderbolt. Heck, USB 3.0 read speed is even faster than my 1TB Fusion drive:
Tested on a late 2012 27" iMac (i7 3.4GHz, 32Gb RAM, GTX680MX) using Disk Speed test by Blackmagicdesign, using the 5Gb read/write test on a 20 Gb FAT partition on the LaCie disk:
- LaCie Rugged 120 Gb SSD Thunderbolt: write: 190.3 MB/s - read: 383.1 MB/s
- LaCie Rugged 120 Gb SSD USB 3.0: write 189.7 MB/s - read 428.2 MB/s
- 1 TB Fusion drive (internal): write 325 MB/s - read 382.7 MB/s
can you tell me if it's possible to enable the trim with the lacie rugged ?
