Series 4 Gb Ethernet NAS – Removable Disk DTU
Targa’s network-attached storage (NAS) device functions as a “server” dedicated to file sharing. Targa’s NAS provides removable SATA Flash disk data storage for single or multi client users over a dual IEEE 802.3ab ethernet link.
Supported Protocols FTP, TFTP, NFS, HTTP, DHCP, iSCSI, PXE (BOOTP/TFTP)
Data Transfer Rates FTP NFS iSCSI
File Reads 30MB/sec 14 MB/sec 20 MB/sec
File Writes 20MB/sec 7 MB/sec 30 MB/sec

Average sustained data transfer rates measured with single client over multiple file transfers. Actual end user data transfer rates will vary depending on network traffic and client system processor loading.
