When you think of shopping for a hard drive, the first criteria you might have set for consideration is its performance. The best performance hard drives are necessary for serious gaming, video editing, graphics designing, servers and workstations.
Price is the the nearest indicator of relative performance of the hard drives, higher the performance more is the price. So, your aim should be to buy a hard drive which apart from delivering high performance fits right in your budget too. The most important specification which contributes to the performance of a hard drive is its speed. This comprises of spindle speed and data transfer rate. In addition, the cache size of hard drives also affect the performance to a good extent.
When drives spin at a faster speed, it takes lesser time to access the data from their platters. Platters are disks stacked together one above another on which drive stores data. You should ideally go for high performance hard drives having a spindle speed of 7200 RPM. There is need for more performance in servers and workstations where the spindle speeds could be 10000 RPM or 15000 RPM.
The foremost essentiality prior to choosing a hard drive is to check that your system and hard drive must support the same standard. There are all sorts of internal and external hard drives present in the market. SATA and SAS (Serial Attached SCSI) are currently dominating the market for performance internal drives' interface. For external drives delivering high performance, Thunderbolt is the newest interface with transfer speed up to 10Gbps but mostly supported on MacBooks without any driver installation.
The actual speed with which drives read or write data is slower than the interface transfer rate. The external data transfer rate should be more than 160 Mbps in these performance hard drives which will decide how fast the data is moved between the drive platters and the computer.
In large production enterprises, probably hard drives with Gigabit Ethernet would perform well as data have to be shared with different workstations. However, heat generation should be controlled in high performance hard drives for servers and workstations. Glass platters are more stable to temperature changes than aluminum platters.
Caching buffer of 16 MB to 64 MB is common in the topmost performance hard drives. While working with large videos and audio files, if data is already in the buffer then for the next request it won't be required to fetch the data from the disk platters all over again. Less time would be taken in data read and therefore performance would increase.
To help you further with your buying decision, we present here our listing of the best performance hard drive of 2013 based on opinions of the topmost reviewers across the web.
