What is nl sas hdd

The cost of the drives will depend mainly upon three key metrics: speed, reliability and storage capacity requirements. For mission critical servers or servers that utilize disk intensive applications I would recommend utilizing SAS drives. For desktops, I usually recommend SATA drives, unless there is a need for local access and performance gains, such as some developers and architects.

Disk access and data throughput can be important and have a noticeable impact upon the user. For non-critical storage, near line SAS drives are usually good choices as the SAS compatible interface allows for more seamless usage command set with server operating systems and array controllers.

There will be outliers and that's where SAS's increased reliability makes it much more palatable. I'm not going to go into great detail about these commands, but will do so in a future article.

While these disks will never perform as well as SAS thanks to their lower rotational rate, they do provide all of the enterprise features that come with SAS, including enterprise command queuing, concurrent data channels, and multiple host support.

However, on the reliability spectrum, don't be fooled by the acronym "SAS" appearing in the product name. However, bear in mind that this is a SATA disk with a SAS interface and, with that interface comes a number of benefits, some of which I briefly mentioned earlier.

These features allow manufacturers to significantly simplify their products. Lowest on the spectrum is the SATA disk. Learn more. Asked 9 years, 5 months ago. Active 9 years, 5 months ago.

Capacity-optimized Solid-state disks SSDs are a higher tier of storage and shouldn't be compared directly with rotating media. Their main characteristic is higher random read and write performance, but the details are beyond the scope of this question.
