Serial Attached SCSI speeds up to 12 Gbit/s. The physical SAS connector comes in several different variants: "Nearline SAS" (abbreviated to "NL-SAS", and sometimes called "midline 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. When compared to SATA, NL-SAS drives have the following benefits: Serial Attached SCSI In computing, Serial Attached SCSI (SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced
IPAQ (desktop computer) to the RAM limit of the Intel 815 series chipset, the BIOS in the iPAQ prevents the system from booting if there is more than 512 MB installed, instructing the user to decrease the amount of RAM in the system to no more than 512 MB. The first version came in two different models, "Legacy free" which had no parallel, serial, or PS/2 ports and instead 3 additional USB ports on the back; and the traditional one which included the parallel, serial, and PS/2 ports but only had USB ports on the front. The second version had different styling and
