This total user area may vary. *4: Transfer rate varies according to product and recording format. *5: Additional recording is supported prior to finalizing the disc. *6: Estimated from Sony's accelerated test. Dual-channel Head System (DCHS) Drive The PDW-U2 and XDCAM Station Series (XDS-1000/ PD1000/PD2000) adopt the Dual-channel Head System (DCHS) for their Professional Disc drive. The DCHS drive is equipped with two optics on one head. This realizes higher transfer speeds in a more compact size and with lower power consumption compared with a drive with two optical heads. High transfer speeds give a significant boost to ingest, edit, and archive workflows. File Read Speed Comparison* Conventional 1 Head Drive 120 Mbps 300 Mbps DCHS Drive 330 Mbps * Drive performance. SxS Memory Cards Combine High Transfer Speeds and High Reliability The PMW-500, XDCAM Station Series, and PDW-HR1/MK1 all accept the SxS memory card.These products can handle the same files as current Professional Disc products and XDCAM EX products. Both SxS PRO™ and SxS-1™*1 memory cards use the PCI Express interface to achieve an extremely high datatransfer speed of 1.2 Gbps via SBS-64G1A/32G1A and 800 Mbps via the other SxS memory cards. These cards can resist considerable shock (1500 G) and vibration (15 G). Also, a unique Salvage function serves to restore content damaged by power loss or memory disconnection during recording*2. *1: SxS-1 memory cards support fewer re-writes than SxS PRO memory cards. Notification is given when an SxS-1 memory card approaches its end of life. *2: In some cases, images recorded just before an accident may not be restored (several seconds). No warranty is given on always achieving content restoration. 4
