Introduction to the Seagate ST336753LW 36GB Ultra320 Hard Drive

The Seagate ST336753LW is a 36GB (gigabyte) hard disk drive with a 3.5 inch form factor. It is designed for high-performance computing environments and features a 15000 revolutions per minute (RPM) speed, 8MB buffer, and a Small Computer System Interface (SCSI) 68-pin interface. In this article, we will explore the technical specifications of the Seagate ST336753LW in detail.

Form Factor

The Seagate ST336753LW has a 3.5 inch form factor, which is a standard size for most desktop computer hard disk drives. It is designed to fit into a standard drive bay in a desktop computer case or server. The drive measures 1.03 inches in height, 4.00 inches in width, and 5.75 inches in length.

Storage Capacity

The Seagate ST336753LW has a storage capacity of 36GB (gigabytes). This means it can store up to 36 billion bytes of data. While 36GB may seem small by today's standards, it was considered a large capacity when the drive was released in 2004.

Rotational Speed

The Seagate ST336753LW has a rotational speed of 15000 revolutions per minute (RPM). This is a very high speed, which makes the drive ideal for use in high-performance computing environments, such as servers and workstations. The high rotational speed means that data can be accessed and transferred quickly, reducing the time it takes for the computer to perform tasks.

Buffer Size

The Seagate ST336753LW has an 8MB buffer. A buffer is a small amount of memory that is used to temporarily store data that is being transferred between the hard disk drive and the computer. The buffer helps to smooth out the flow of data and can improve the overall performance of the drive. The 8MB buffer on the Seagate ST336753LW is relatively large and helps to ensure that data transfers are smooth and efficient.


The Seagate ST336753LW uses a Small Computer System Interface (SCSI) 68-pin interface. SCSI is a type of interface that was commonly used for high-performance hard disk drives in the past. While SCSI is no longer as widely used as it once was, it is still found in some older servers and workstations. The 68-pin interface on the Seagate ST336753LW is a standard SCSI interface that provides a fast and reliable connection between the hard disk drive and the computer.


The Seagate ST336753LW is compatible with a wide range of operating systems, including Windows, Linux, and Unix. It is important to ensure that the operating system being used supports the SCSI interface and the 68-pin connector used by the drive. Additionally, the drive requires a SCSI host adapter to connect to the computer.


The Seagate ST336753LW is designed for use in high-performance computing environments, which means it is built to be reliable and durable. It features advanced error-correction capabilities that help to ensure that data is not lost or corrupted during transfer. The drive is also designed to be resistant to shock and vibration, which can help to reduce the risk of data loss due to physical damage.

In summary, the Seagate ST336753LW is a high-performance hard disk drive that was designed for use in demanding computing environments. It features a 36GB storage capacity, a 15000 RPM rotational speed, an 8MB buffer, and a SCSI 68-pin interface. While it may not be as commonly used today as it was when it was released in 2004, it remains a reliable and durable choice for older servers and workstations.

About New Bulk Pack Products

New Bulk Pack products come with clamshell boxes and do not have any manufacturer warranty. Many times manufacturers disassemble whole units to use parts or pulled from a new system. Typically, this product doesn't come with software or instructions unless indicated and no Manufacturer’s genuine warranty. You can take note these are not brand new products.

The ultra320 SCSI hard drive generation is the immediate upgrade of its predecessor, the ultra160 SCSI. The newer generation ultra320 SCSI HDD comes about as an implementation of the SCSI-3 Parallel Interface-4 (SPI-4) standards.

Over its lifetime, the SCSI standard is widely used in servers and high-end workstations. It is possible to install SCSI HDDs in a desktop PC that has one or more IDE disk drives. The IDE drive acts as the boot drive, while the SCSI hard drive provides additional storage capacity. SCSI is not commonly used in desktop PCs, although it allows the addition of a scanner and several other drives such as DVD-RAM, CD-Rs, and Zip drives to a single SCSI cable chain. USB and FireWire have gradually replaced the SCSI as alternate interfaces in the latest desktop PCs.

In-network servers, SCSI allows for the setting up of several hard drives in the RAID configuration to reduce the risk of loss of data. The configuration supports hot-swapping - the changing of hard drives while the system is still operating.

Ultra320 SCSI HDD just as the name suggests delivers 320 Mbps top speed and provides a faster bus at 80 MHz and a wider data path at 16 bit. Connections with the Ultra320 SCSI HDDs just like with SCSI devices can be daisy-chained since they have two ports - the incoming and the outgoing cables. Besides, SCSI has a strong commitment to backward compatibility with previous generations, which explains its widespread use as an I/O interface and the elimination of the need for substantial investments in equipment and infrastructure. Migration to the ultra320 SCSI HDD is smooth whether it is from the Ultra160 SCSI or other generations of the SCSI standard because of backward compatibility.

The ultra320 SCSI hard drive takes on technologies such as domain validation, cyclic redundancy check, and dual-edge clocking first introduced by ultra160 SCSI. Additionally, the ultra320 SCSI hard drive introduces protocol changes and other technologies that enhance performance and support reliable data transfer speeds at 320 Mbps. We have the following ultra320 SCSI HDD options: 146GB-10K RPM, 146GB-15K RPM, 300GB-10K RPM, 300GB-15K RPM, 36GB-10K RPM, 36GB-15K RPM, 73GB-10K RPM, 73GB-15K RPM, and 18GB-15K RPM to meet your performance and storage requirements.

The standard features of the ultra320 SCSI hard drive include:

  • Two-fold increase in transfer speed: The ultra320 SCSI hard drive increases the transfer rate by 100% from the previous generation at the rate of 320 Mbps. The technology allows greater transfer rates, effectively leading to greater performance in environments of extended data transfer and support for many devices on a single bus.
  • Support for SCSI packet protocol: By enabling packet protocols, the ultra320 SCSI HDD helps to reduce command overhead by using dual transition (DT) data phases to transfer data, commands, and statuses rather than asynchronous phases that are generally slow. Packet protocol allows for the transfer of multiple commands in one connection as well as increased performance through minimal command overhead and maximum bus utilization.
  • Quick Arbitration and Selection (QAS): the technology helps reduce control release overhead between devices at the SCSI bus. QAS is all about reducing command overhead and maximizing utilization of the bus.
  • Read/Write Data Streaming facilitates the reduction of overhead associated with data transfer through the sending of a LUN Q-TAG (LQ) data stream packet, which is subsequently followed by multiple data packets. Greater write data streaming is achieved since the bus turnaround delay is eliminated between LQ and data packets.
  • The flow control feature facilitates the initiator to enhance the pre-fetching of data for writes and enhance the flushing of FIFOs for reads.
