5TB hard drive is here, inside LaCie's latest Thunderbolt storage systems

The hard-drive capacity race has just started again as LaCie announced today the availability of a 5TB internal hard drive in its three Thunderbolt series, the 5big, the 2big, and the d2.

This is the first time a new capacity was announced not by the original maker, which is Seagate in this case. However, LaCie has been part of Seagate since 2012. This is a SATA3 Desktop HDD internal drive that spins at 7,200rpm, model number ST5000DX000.
The addition of the 5TB drive option (up from 4TB) means that LaCie's Thunderbolt series can now up its top capacities by 20 percent. The 5big Thunderbolt storage device, for example, now offers up to 25TB of raw storage space.

(The first 5TB internal hard drive is a Seagate Desktop HDD model ST5000DX000.)

The new capacities are also available for the LaCie 2big Quadra and d2 Quadra storage products, which are available now. The new storage capacity won't affect the devices' performance. That said, you can expect top speed from the 5big Thunderbolt
