SCSI vs SAS Hard Drives – What’s Better?

Technical terminologies associated with computer hardware are always something you don’t hear on a regular basis, and so it turns out, hard drive terminology is also very confusing and putting off for the ones who aren’t tech savvy. Take SCSI and SAS for instance, these two terminologies are definitely not considered to be one of the most known terminologies among people. Figuratively speaking, people who are in the IT business and industries should know what these abbreviations mean.

Our IT experts at Memory Clearance have explained the difference between both SCSI and SAS hard drives in this quick overview. In this post you will learn what are SCSI and SAS hard drives and the key differences between various enterprise drive interfaces.

What is a SCSI Hard Drive?

SCSI is an acronym commonly associated with hard drives which seemingly stands for Small Computer System Interface, pronounced as ‘scuzzy’. Figuratively, SCSI hard drives significantly have been the crucial backbone of enterprise computing for nearly 20 years. Although, SCSI hard drives aren’t much popular when it comes to storage capacity primarily because the last generation of the SCSI hard drives comprised mostly 36GB, 73GB, and 146Gb models. Despite the small storage capacity, these hard drives make up for it with the speed.

Primarily, SCSI drives come in 10,000 or 15,000 rotations per minute (RPM) variants, which simply refers to the accessing speed of data, much faster than a desktop computer (desktop hard drives generally rotate at 5400 or 7200 RPM). SCSI hard drives are a great option for mission-critical applications that aren’t too beefy and need to be accessed quickly.

What is a SAS Hard Drive?

SAS is also an acronym associated with hard drives, which stands for Serial Attached SCSI, and can be necessarily considered the beefy version of a SCSI hard drive. And when it comes to running mission critical applications, an SAS hard drive is a better choice . SAS hard drives have relatively faster data transfer speeds (3 or 6GB/s, compared to the max transfer speed of 5120 MB/s of SCSI hard drives). Not only that, SAS hard drives come with thinner cables, and are very conveniently connected with SATA drives.

SCSI vs SAS: What’s the Best Choice?

The difference between both SAS and SCSI hard drives is not so phenomenally to be affecting your decision. But, these differences should be taken into consideration when you’re out buying for your IT needs and requirements.

– Speed & Data Transfer Rate

SCSI has a decent speed, but SAS offers greater speed.

– Capacity

If Capacity is your primary concern, then SCSI is a much better option.

– Price

SAS comes rather expensive than SCSI, which makes SCSI a viable affordable option.

The Bottom Line:

In the end, it all squeezes down to the personal preferences or your IT needs and requirements that incline you to make your decision. The bottom line is that the hard drive interface is typically just one choice when you’re out buying a desktop computer memory, server memory, CPU, drive bays, RAID controllers, etc. All these factors must be taken into account that can play a crucial part in your decision making.
