SSD cache in NAS storage will help you extend your hard disks’ life and improve read and write speeds in complex enterprise NAS environments. In addition, SSD cache in NAS storage can help to increase performance and stability. To be more specific, it makes reading and writing data from the disk as quickly as possible.
Any optimized Network Attached Storage system uses SSD cache to increase performance and speed up read and write requests. This post explains why you should use SSD cache in your enterprise NAS storage. It can enhance your storage solution’s performance, reliability, and longevity.
Increased performance in Random reads and writes.
A hard drive is comprised of an actuator that moves the arm that reads and writes. And as well as a spindle that lets the platters move. A conventional hard drive functions best for sequential reads. This means that data is kept in one place. And the head of the read/write need to alter its position on the platter. But, when dealing with random write or read requests, it is not the case. Where the data is scattered across the platter in smaller c犀利士
hunks. It can lead to noticeable delays because the head of the read/write must change its position frequently.
This is the area where an SSD can make a significant difference. Since an SSD is composed of flash memory with no moving components, they’re quicker and deliver many superior IOPS (Input/Output Operations Per Second) performance. The addition of the SSD for use as a in your your NAS provides much higher performance when you’re dealing with lots of tiny files like databases or operating an email server website directly from the NAS.
SSD caching in NAS storage IOPS-intensive tasks
Now, if we talk about, SSD caching, it is offered on the Best NAS systems, and it’s intended to boost the performance over a conventional hard drive. Another point, SSD cache provides the perfect alternative if you’re looking to run large-scale file-based workloads on your Network Attached Storage.
It is essential to have an SSD cache that frequently accesses data and acts as a buffer so reads and writes can have noticeable performance improvements. There are two types of SSD caching available on NAS appliances:
Read-only cache When this is enabled, just the data used most frequently is stored in the cache to boost the speed of random reading. Since no writing is required so there’s no risk of lost data should the SSD be affected by any issue.
Read-write cache The read-write cache writes data onto the SSD. We suggest the addition of two SSDs in a RAID 1 configuration to ensure the integrity of data because there will be write operations on your SSD.
When deciding on SSDs to be used as cache, we recommend considering its durability, typically measured in the form of TBW (terabytes recorded). This figure indicates the number of terabytes that will be written onto the SSD before it is exhausted. We suggest checking StoneFly’s tailor-made enterprise NAS storage appliances or even SAN solutions, that offer Flash SSD caching and automatic storage tiering for extended and reliable performance.
