In this Presentation, we have discussed SAS vs SATA. If you are interested in knowing the differences between SAS vs SATA, then it is very helpful to you.

1. SAS vs SATA: The
Key Differences That
You Should Know
Here is where your presentation begins

2. Introduction
SAS is an acronym for Serial Attached SCSI or Serial Attached Small Computer System
Interface. And SATA is an acronym for Serial ATA or Serial Advanced Technology
Attachment.
SAS and SATA connectors are used for connecting the components of the computer to
motherboards, like hard drives and media drives. However, hard drives which are based
on SAS are quicker as well as more reliable than the hard drives which are based on
SATA. But, SATA drives offer significantly higher storage capacity. SAS drives are utilized
for servers because they are fast and dependable, whereas SATA drives are utilized for
personal computing and are less expensive.
In this blog, we will discuss about some differences between SAS vs SATA that are
essential ones.

3. What Is SAS Storage?
SAS (Serial Attached SCSI) is the recent evolution of the SCSI interface
drives that are utilized in higher-end workstations and servers. Most
current servers use HDD or SSD drives, just like consumer computers,
but they’re quicker and more reliable.

4. Benefits /
Advantages Of
SAS Storage

5. 1. Faster Throughput
SAS drives can read/write and process data in a fraction of the time it takes SATA
drives, especially for random reads/writes and with the newest 12 Gbps disks and
RAID hardware controllers. And at sequential data, SATA is a good one, but it is
terrible at random IOPS.
2. Better suited to 24/7 workloads
For servers, SAS is designed and frequently has 100% duty cycles. SAS is
designed to read/write data every day, unlike SATA drives for your home desktop,
which have 20-30% duty cycles.

6. Disadvantages Of SAS
Storage
1. SAS drives have a higher cost
SAS drives are around four times more costly than SATA drives.
And the cost for the SAS enterprise starts at $1/GB, it’s simple
to see why most hosts only provide SATA as a default option
for dedicated servers.
2. Higher electricity consumption
SAS consumes more electricity than SATA. In comparison to a
SATA or ATA disc, a SAS drive can need at least twice as much
signaling voltage.

7. What Is SATA Storage?
SATA (Serial ATA) is the recent evolution of the ATA hard drive. It is
done in the 1990s and early 2000s and moreover, it is utilized in the PC
desktop computers. Today’s PCs always come with SATA-II or SATA-III
ports, and SSDs are becoming more common.

8. Benefits /
Advantages Of
SATA Storage

9. 1. Cheaper than SAS
As compared to SAS drives, SATA drives are 75% less expensive. As a result,
hosting companies provide more storage space at cheaper prices – or at a bigger
profit margin.Customers that have a dedicated server can take benefit of
additional storage, such as backup drives.
2. Sequentially fast
SATA is excellent at writing in sequential order and it has a throughput of 6 Gbps
and can write at that rate if no random reads/writes are present.

10. Disadvantages of SATA
Storage
1. Bad random read/write performance:
Random read/write seek and storage delay are comparable to
a racing car’s cornering abilities on a track.Taking the bend is
more difficult than going straight (sequential). And random
read/write requests cause a SATA drive to crawl.
2. Uses the CPU
SAS has an enterprise-class data management system,
whereas SATA does not. Data flow management is delegated
to the CPU through SATA. As a result, disc I/O spikes have a
significant influence on the system load average.

11. SAS Vs SATA: The Key
Differences
1. Speed
The quantity of data that can be transferred, processed, or read and written in a certain
length of time is referred to as throughput. Drive throughput is benchmarked or measured
to determine drive speeds. SAS drives often have better throughput than SATA drives
since there are fewer delays in general. However, in the slower SAS and faster SATA
drives, there is some overlap between them.

12. 2. Storage Capacity
SAS gives priority to speed over storage. As a result, the majority of SAS drives on the
market have less than 500GB of hard disk space. Those with more than 500GB of storage
capacity might be rather costly.
On the other hand, SATA emphasizes storage; therefore, finding a cheap SATA drive with
1TB or more capacity is simple.

13. 3. Reliability
SAS is built for 24/7 use in companies, such as data centers, which is a key distinction
between SAS and SATA. While SATA drive is used technically in the same way as a SAS
drive and it would be slower and more likely to fail. Organizations that rely on trustworthy
hard drives this is an expensive problem. A SAS drive’s MTBF (mean time between
failures) is 1.2 to 1.6 million hours of use at 45 °C, whereas a SATA drive’s MTBF is
700,000 to 1.2 million hours at 25 °C.

14. Conclusion: SAS Vs SATA
Here, we have discussed SAS vs SATA. And, for the students to understand the essential
differences between the terms SAS vs SATA is very useful. And we hope that now you
have got all the information related to SAS vs SATA.
