IBM 49Y1871, 49Y1874, 49Y1875, 1746-5175 2TB 7.2k 6Gbps NL-SAS 3.5″ HDD Technology

NL-SAS drives have a SAS interface, but head, media, and rotational speed of traditional enterprise-class SATA drives, so they cost less than other SAS drives. This interconnect technology is capable of communicating at speeds of 6Gbps. Increase your available storage with the IBM 49Y1871 2TB 7.2k 6Gbps NL-SAS hard drive. When compared to SATA, NL-SAS drives have the following benefits:

  • Dual ports allowing redundant paths
  • Ability to connect a device to multiple computers
  • Full SCSI command set
  • No need for using Serial ATA Tunneling Protocol (STP), which makes it possible for SATA HDDs to be connected to a SAS HBA
  • No need for SATA interposer cards, which are needed for pseudo–dual-port high availability of SATA HDDs
  • Larger depth of command queues
