Install the LaCie d2 SSD Upgrade on the LaCie d2 Thunderbolt 2 (sold separately) to multiply speeds by a factor of five, with zero compromise in capacity. At up to 1150 MB/s, the LaCie d2 with the d2 SSD Upgrade delivers speeds that exceed the performance of even the internal SSD on your late-model PC or Mac computer – in a single-disk enclosure.

Simply remove the rear panel on the LaCie d2 Thunderbolt 2 to install the upgrade, and instantly you have an additional 128 GB of SSD storage. Two separate drives mount on the computer: one for the SSD, and one for the hard disk. Use the SSD for bandwidth-intensive tasks such as fast file transfers, audio mixing, video editing, or OS booting, and use the hard disk for file archiving. No other solution offers this level of performance and capacity in such a compact footprint.
