SSD Array vs HDD Array

With the emergence of SSD arrays, businesses are starting to question the more traditional HDD arrays that have been standard storage solutions for decades. And with the ever-growing presence of critical data across countless industries, it’s no wonder that the more sluggish spinning drive arrays are being put into question. But is the concern warranted?

Our SSD Array vs HDD Array comparison will help lay out the benefits and limitations of each, while helping determine which solution fits specific business needs.

HDD Arrays (Spinning Drives)

Enterprise-level HDD arrays group a series of spinning disk drives to form a much larger logical disk structure. These types of arrays have been industry standard for years, and are relied upon for their ability to store huge quantities of data. Many companies make heavy use of RAID arrangement with these arrays, utilizing full redundancy so systems continue to run properly if one component goes down. Limited downtime, reliability, and the ease of expanding storage for a low cost have kept many businesses happy for a long time.

But when it comes to performance, spinning drives don’t hit the mark for businesses operating in high IO environments. IO read/write requests are directed to physical disk locations, and data is retrieved with the help of a “head” (similar to a needle on a record player). This process results in data taking longer to find due to the physical movement of parts when retrieval is required. The sluggishness of these read/write requests is exacerbated by fragmentation, where files are stored in smaller bits and pieces across an array.

SSD Arrays (All Flash)

SSD Array - StorTrends 3610iSSD arrays, otherwise known as all-flash arrays, utilize the strengths of Solid State Drives and flash memory. Simply put, these arrays put emphasis on performance. Their incredibly fast data transfer speeds result from having no moving parts. With high IOPS and low latency, SSD arrays are perfect for businesses dealing with high-performance computing, financials, and any other applications that place heavy value on speed.

And while SSD arrays are certainly the future of storage, they do have their limitations. Expanding SSD array storage capacity is considerably more difficult when compared to HDD arrays. Furthermore, all flash storage arrays are still at a much higher price point (although that price is declining rapidly). So while SSD performance is league’s beyond their HDD counterparts, businesses operating with vast amounts of expanding data still need spinning drives in their array.

Compromising with Hybrid Arrays

Many businesses want a mix of performance and storage capacity, and hybrid arrays provide a nice compromise between the two. Hybrid arrays place SSD storage on the front end acting as a cache for your systems, and HDD storage on the back end for expandable storage capacity and archival usage.

JBOD vs NAS Storage: Which is right for my business?

They’ve both become commonly used storage solutions for businesses of all sizes; and while NAS (Network Attached Storage) sales have exploded over the past couple of years, JBOD (Just a Bunch of Drives) still adequately meets many storage demands depending on business needs. A company’s value of storage capabilities, speed, redundancy, cost effectiveness, and more dictate what solution best suits that business.

So what benefits should you be aware of when it comes down to JBOD vs NAS storage?

JBOD (“Just a Bunch of Drives”)

JBOD traditionally refers to either a single disk or architecture of multiple disk drives presented to an operating system as a single entity. JBOD has no actual RAID functionality, which comes as a turnoff for businesses seeking redundancy and performance improvement.

JBOD storageThis solution strips out the extra bells and whistles and places emphasis on the ability to continuously expand storage space easily. If you see you’re fast approaching your current memory capacity, simply add another drive to the disk enclosure. Furthermore, JBOD storage avoids drive waste unlike some RAID configurations that can lose storage volume when combining drives of varying capacity (although best practice tells you to stay consistent with disk size). And even though the price of disk drives continues to drop, JBOD still stands as one of the most cost effective solutions on the market.

As mentioned earlier, there are potential risks that come with JBOD storage systems that stem from RAID inabilities. Due to lack of redundancy, losing data on a single drive may also result in lose of data on the other drives as well. If a backup system isn’t in place, that data is gone for good.

NAS (“Network Attached Storage”)

As opposed to JBOD, NAS devices function as storage directly connected to your computer network through an Ethernet connection. NAS systems typically utilize hard drives in a RAID configuration, providing redundancy and speedy access to files across your network of computers.

NAS storageTraditionally a pricier option compared to JBOD, costs of NAS solutions have dropped dramatically over the past couple of years resulting in 46% sales growth. NAS is the answer for businesses willing to pay a slightly higher price point for performance enhancement and the redundancy RAID configurations provide. A continuous backup of your data is invaluable, and the ability to separate storage resources increases data availability across your network.

It’s important to note that NAS does display some weaknesses when it comes to dealing with large amounts of data transfer. For businesses utilizing these types of applications, be aware that prolonged use of NAS for this type of work can slow the LAN.

Finding the right storage solution for your business is a tedious, but crucial decision.
