- Yes, all 2big docks are the same, only capacity is different.
- APFS possible, but HFS+ partly more stable for HDD.
- In the Finder depending on the mode: RAID 0/1 = 1 volume, JBOD = 2 volumes.
- Partitioning is possible, depending on the RAID setup.
- Daisy-chaining possible with TB3/TB2 adapter, bandwidth is shared.
The LaCie 2big Dock models can be connected individually to your iMac as separate storage devices. They are not designed to work together in a single RAID configuration across different units. Each unit operates independently, allowing you to use them as distinct storage solutions.
The power supply is rated at 60W, but the exact power consumption in operation is not known. We haven't found a report, and the manufacturer makes no mention of this.
To get an answer, we'd have to measure consumption at the outlet with a suitable device, but we don't have the ability to do that. Sorry, we can't provide a more accurate answer.
Thanks for the answers, Virginia Perrotta. I'm surprised that the 2big Dock is supposed to have raid capabilities - because LaCie explicitly offers the 2big RAID product. I had imagined that I would either get two individual, independent hard drives (where the failure of one does not affect the second), or a complete hard drive package (with the risk of data loss if one of the two drives fails) - previously known to me as JBoD. However, the answer now says that JBoD is exactly the opposite, i.e. two volumes which, as I understand it, should not cause any data loss to each other if one drive fails. As an alternative, I would have to buy two external drives with an enclosure, and I'm not hearing much good from LaCie, now Seagate.
Your assessment is absolutely correct, here is a clear explanation:
- All 2big Dock models (Thunderbolt 3) are technically identical, differing only in capacity and the installed drives.
- RAID capability: Yes, they are RAID-capable - there is an internal RAID controller (RAID 0, RAID 1, JBOD). The "2big RAID" is basically the same device, only with a simplified setup tool for pure RAID use.
- JBOD (Just a Bunch Of Disks) means two independent drives that appear separately in the Finder. If one fails, the other remains intact.
- RAID 0 = one large disc (fast, no protection).
- RAID 1 = one mirrored disc (slower, but more secure).
- APFS works, HFS+ often more stable for classic HDDs.
- Daisy-chaining via TB3-to-TB2 adapter works without problems, but the total bandwidth is shared.
You can use the 2big dock exactly as you described, two completely separate drives without mutual risk.
The silver external hard drive 10952874 has actually still been in our range since 2020 and has been completely sold out at almost all suppliers for some time. Some suppliers still sell the remaining stock. This variant used to be much cheaper - but the current purchasing conditions lead to a higher price. The black variant has been on sale since 2022. Such price differences cannot always be attributed to the technical properties. Since we work with different suppliers, the procurement conditions also influence the sales price.
