First, let’s have a look at the main variables related to such storage device connections that may help to understand the nature of SATA vs SAS rivalry. See how both serve your business and data management, and what you should consider once choosing between them.
Storing and exchanging data as the basis for business operations
SATA and SAS – The Veins of the Storage Organism
There are a couple of aspects related to the best efficiency for data management. One of them relates to the storage devices (disk types) you are going to use to store the data. The other is the connectivity, or more precisely – the interface that connects them to your motherboard or power source. SATA and SAS are responsible for that – like veins connecting the organs, they fuel the drives with data and give them the power to work. Price and performance aspects are most often considered when deciding which to choose. It’s crucial to be confident about what your business needs, as not always spending more money (price aspect) guarantees choosing the proper hardware and optimizing the data management (performance aspect) in your business.
HDDs and SSDs – The Foundation of Storage
Let’s focus on HDDs vs SSDs first. Both come with features you have to think about before building your storage unit. Noisy, slower Hard drive diskswith spinning platters are cheaper and able to keep large amounts of data but are less tolerant to physical faults, so you have to handle them with care. On the other hand, more expensive, quiet flash solid-state drives work faster, allowing you to transfer data in the read-write process rapidly. These are flash disks, so they use flash memory chips. They are shock-resistant and more tolerant of physical damage, do not overheat as much as HDDs, but are less tolerant of power failures, which may also lead to the worst scenario – data loss.
So it’s important to choose the proper drive type, but the SATA and SAS interfaces will definitely impact your decision. Bear in mind SATA disks are cheaper looking at the storage space available. The more modern SAS interface is server-oriented and supports mission-critical applications. This kind of reliability makes the price higher for each. Both come with some advantages and disadvantages and their own specifications you need to be aware of before making the final decision.
“But is there anything that makes this decision easier?” you may ask. Of course – it is the purpose and method you process the data.
Data Management – Storing vs. Exchanging
It’s important to decide what is essential for your company – to store or constantly exchange data. Many business types (i.e. education, media industry, healthcare, or any other) rely on data management,so make sure what’s crucial for you – that it’s kept and written on the drives successfully, or multiple users can use them at any time. It’s the point when you can decide how to spend your financial resources to make sure your company will operate effectively without any data or performance loss.
SATA Utility in Your Business
Choosing the SATA solution is a smart decision if your business is mainly based on or requires data archives, backups, and file storage. Drives connected this way have a higher storage-per-price ratio that constantly changes for the better. It uses less electricity than the SAS interface, hence, it’s not only cheaper but also lowers the costs of its performance and power consumption. This allows you to save more money. The energy price went higher significantly over the last few years for household and non-household consumers. Data management requires using a lot of power-consuming equipment, thus, you may find it worthwhile to look for savings this way.
SATA cables are more flexible and can be longer, which is a good thing in case of connectivity. Another advantage is backward compatibility, which allows connecting SATA III (the latest version) to older ports – I and II. SATA is also widely compatible with commodity hardware and different components.
Using SATA drives and interfaces saves you more money this way – there’s no need to spend it on faster solutions if only storing is the thing.
SAS Utility in Your Business
The performance is the first main advantage of SAS over SATA. It’s more server-oriented, mission-critical applicable, and handles multiple requests simultaneously. It’s possible because SAS reads and writes data at the same time. Everything, all, at once. Therefore, SAS is much faster, especially with random reads and writes. The transfer rate is up to 12 Gbps, whereas SATA is 6 Gbps only. So if your business mission is managing content on a website or exchanging live data – consider going with SAS.
The hardware interface architecture is also better. The SAS connector contains data and power cables. They are more expensive but more durable in return. SAS interface uses fewer cables, thus, is easier to handle, but if you’d like to attach more disks – you can use expanders.
The last thing worth mentioning is the possibility of data falsification. Unlike SATA, the SAS interface offers checksumming functionality during the data transfer. It’s worth mentioning in regard to the impact it has on data integrity. The probability of data falsification after transfer with SAS is lower, so you can be even more sure that the data sent are the same as the data received.
Take Time to Set Priorities
As you can see, deciding which interface is better requires a couple of things to be thought over. Besides determining if storing or exchanging the data is the priority, it is worth checking what kind of hardware we already have. Old units tend to operate on SATA. If you use that already and your business does not rely on data transfer both ways with fast reads and writes – maybe it’s better to stick to that. On the contrary, if you are ready for some future expenses and constant data access is crucial – maybe it’s the right time to switch your environment to SAS. The same goes for building the data management structure from scratch. Once you are sure how the business will operate – you’ll choose the right way.
