Selection of the right hard drive for data storage on a dedicated server and transactions is crucial for your business, because sensitive data plays an important role for functioning of your business. Your decision concerning storage infrastructure and disc performance should be based on demands of your business, or dedicated host server. Particularly, you should pay attention to such characteristics of storage discs as capacity, speed and price (in this very order).
Today, there are three different kinds of drives: SSD, SAS and SATA. To understand which drive is better for dedicated hosting server hardware, we should dig deeper into their utilities, pros and cons. Let’s compare these disc technologies to make the right decision.
SSD stands for Solid State Disk. This is a storage device that features zero mechanical moving component. When applied on dedicated hosting, it has the following benefits:
- It works strikingly fast and provides exceptional speed, because it has no moving parts.
- Operational cost is lower, since such solution is less prone to mechanical damage.
- It needs less power, because less heat emission makes up for low carbon footprint.
- It produces no noise.
Disadvantages of SSD Drives include:
- It costs much higher than all other drives.
- Although SSD provides higher performance, it is more vulnerable to power loss and current fluctuations.
- It consumes more battery powers in laptops.
SAS stands for Serial Attached SCSI. It is connected directly to the disk drive in a point-to-point interface, which allows functioning in a dual port. If one controller fails, the redundancy will still say high, so user can enjoy uninterrupted functioning.
Advantages of SAS Drives for dedicated servers:
- Exceptional performance with 15000RPM, which makes up for high bandwidth.
- SAS is pretty flexible: you can customize the configuration, and it’s compatible with different platforms, because disk drive interface controller can be connected directly with the disk drive.
- Its price is lower than of SSD’s.
- It offers a higher scalability and scale more than 100 drives in comparison with only 600mb of SSD.
Cons of SAS Drives:
- It’s more expensive than SATA.
- This technology consumes more power and physical space than SSD technology.
- Its performance is a bit less reliable than in SSD.
SATA, short for Serial ATA is connected with mass storage devices, including ptical drives or hard disks, via a bus interface.
It has the following benefits for dedicated servers:
- It costs much lower than SAS and SSD technologies.
- Its storage capacity can reach 3TB, which is higher than in SSD and SAS.
Disadvantages of SATA Drives:
- Only 7200 RPM of rotational speed, which is lower than even half of SAS. It also means that performance is lower.
- A separate SATA port is required to be on the computer motherboard, while SSD and SAS may be connected to several devices with optical drive and hard disc drives.
Now when you realize all pros and cons of these disc technologies, you can compare them with your storage requirements and decide which one is more suitable for resource optimization on your dedicated web server.
