Important Tips for Choosing the Right Hard Drive

The IOPS discussion is part of Sturridge’s performance, specifically in the area of ​​devices and hard drives such as HDD, HHDD and SSD, and is applicable to cloud, virtual environments and older devices.

Anyone working in the IT field must have sufficient knowledge of the storages, servers, and IO programming capabilities and as a system administrator to meet the needs of their customers and systems.

The vendors are trying to keep their customers, so the global market for HDDs and SSDs is no slouch and should actually be able to guide customers in purchasing the equipment they need.

There are many old and new ways to measure IOPS that you can use depending on the device you are using. By device type, standalone hard drive, hybrid hard drive (HHDD) and SSD, or connected storagesystem or RAID controller .

Server, Storey and IOPS performance and market conditions

The rotation speed (RPM) of the drives is very varied and the drives are either 1.5Gb, 3.0Gb, 6Gb or 12Gb SAS or SATA or 4Gb optical fiber.

Most current generations of 2.5-inch 10K hard drives have the same or even better performance than older 3.5-inch 10K generations.

One of the features of the drives is their physical size: 3.5-inch (LFF) and 2.5-inch (SFF). Today, standard drives come in a variety of thicknesses of 2.5 and 3.5 inches.

Other features of the drives include their use, whether it can be used for a large set or for home use, or you might even be looking to sell it. It all depends on the amount of cache drive (DRAM). It doesn’t matter if you use the whole or part of the drive capacity, in any case the capacity of the drive space can be very impressive. No matter whether you use SAS, SATA, USB port, HBA or RAID controller, you should pay attention to the physical space of your device .

If you want to check the status and performance of these drives over other brands, you should know that drives are measured based on synchronous read and write methods on the drive and delay in response.

The difference between the number of drives and the number of read and write heads is the difference between the drives. There are many types of 2.5-inch hard drives available in the market that have changed over time.

Density refers to the amount of hard disk space. Various sized hard drives have different capacities. Two drives of the same size may have different capacities, or a smaller size may have a larger capacity. You have to choose one of these variations based on your disk usage.

In addition to the physical specifications, technical and logical considerations should also be considered, including: the type of workload, the size and size of the IOPS, the read and write sequences, or a combination of both. Other features, including file system type or raw capacity of the device, number of users, current IO Threads, physical storage space, etc. affect our decision to choose the hard drive . It will also depend on whether the device is new or outdated.

Tools and their performance in performance

There are a variety of tools for measuring IO and workload. These tools include Bonnie, Iometer, Iorate, IOzone, Vdbench, TPC, SPC, Microsoft ESRP, SPEC and netmist, Swifttest, Vmark, DVDstore and PCmark 7 and more.
