Scalable Solution

RAID Modes and Diskless Enclosure Model

This LS441DE is equipped with four internal drive bays. Along with the normal operating mode, installation of four hard disk drives provides you with four additional RAID modes (RAID 0/1/5/10) to select from according to your needs, for protection of system backup data, work data, photo and video data, and other important data from unexpected drive failure.

Quick Install Drives

Hard drives are easily accessible via the front panel.

Advanced Features

Sleep Mode

The LinkStation features a Timer ON/OFF function that allows the power to be switched on only at predetermined times. This both enhances convenience in using the NAS and conserves energy, and prevents wasted electricity from forgetting to switch the power off. The reduction in wasteful power consumption after office hours, on days off, or anytime the drive isn't needed also reduces CO2 emissions and helps the Earth's environment.

*Supports playback of files on up to five computers and transfers to iPods.

NAS Navigator

Easily find and connect to your LinkStation using the NAS Navigator tool. NAS Navigator finds all NAS devices attached to your network, making it easier to manage multiple NAS devices.

"BitTorrent" Support

You can download and share files directly from your LinkStation and you can manage downloads from anywhere using the simple Web-based download manager.

No reformatting is required for external HDD & SDXC

This unit supports the exFAT format employed in the NTFS and SDXC systems used by many computers, so there's no need to reformat disks used as additional storage. However, connection of SD cards and other such media requires a separate card reader.
