Thank you for viewing. This is a LaCie external hard drive with 3TB x 2 for a total of 6TB. ◆ Specifications Product Weight: 3.6 kg Model Number: LCH-2BQ060Q3 Dimensions: Width 9.1 cm x Height 18.3 cm x Depth 20.0 cm HDD Capacity: 6TB (3TB x 2) Connectors: FW800 x 2, USB3.0 B x 1 RAID Function: RAID 0/1 Factory Format: HFS+ RoHS Directive: ○ It contains two 3TB HDDs, and you can choose to use RAID 0 or RAID 1. Daisy-chain connection, where HDDs are connected in series with a cable, is also possible, supporting small-scale server configurations with up to 6 units connected. ◆ Condition I used it a little for data storage testing, so the number of power-on cycles is only about 40, but the usage time is over 5000 hours (photo 7). The status is normal in LaCie's Desktop Manager (photo 10). I haven't moved it around much, so there aren't many scratches or stains (it's a little bit if you look closely). ◆ Accessories ・Main unit ・USB B - USB A cable ・FW800 cable ・Power adapter There is no software CD or manual, but I have installed the default apps (see photo 9). Photos 11 and 12 show the RAID 0 and RAID 1 states. Photo 13 shows how to switch RAID. You can find it by searching the internet, but please use it as a reference. There is no original box, so I will pack it in an empty box and ship it. Thank you.
