Using modern hard disk drives with legacy RAID controllers

Using modern hard disk drives with legacy RAID controllers

Often, as technology moves on in one area, incompatibilities arise that require wider upgrades to keep a system operating. A Toshiba customer was confronted with this situation, as he wanted to continue to use a 10-year-old RAID controller, pairing it with modern hard disk drives (HDDs). He was curious: would it be possible to upgrade a storage subsystem with a really old RAID controller, which still provides stable operation, using modern hard drives with higher capacities?

Toshiba confirmed that their MG08 SATA drives were not checked for compatibility with controllers of that age. Nevertheless, the Toshiba team wanted to support the customer in his attempt to upgrade his system in a sustainable way.

So, they supplied two 16TB SATA (MG08ACA16TE) drives that had been updated to the latest firmware version 0103.

Upon testing, the customer was impressed with the performance, especially the low levels of vibration during idle, writing and reading.

Validating HDD Storage System Performance in a Real-World Context

Small and medium-sized businesses (SMBs) now find themselves having to deal with far greater amounts of data than they would have ever imagined in the past.

Case Study: Cost-Optimised HDD Solution Meets Exacting Demands of Surveillance Sector

Thanks to the advent of IP technology and the development of multi-megapixel high-definition (HD) cameras, the proliferation of surveillance systems and their performance capabilities have increased dramatically over recent years.

HAMR vs. MAMR – Microwave technology delivers higher storage densities in hard disks

We are generating more and more data which needs to be stored safely and effectively. Hard disk drives (HDDs) continue to be central to solving this challenge, requiring them to be available with increased storage capacities. In order to provide the necessary technical solutions, engineers are now looking to incorporate microwave-based technologies into HDDs. As cloud services, video streaming and social media continue to increase in popularity data volumes are growing rapidly, challenging data centers to grow their storage capacities to cope with demand. As a result, many large IT companies are planning to add additional data centres to drive capacity higher.

MTTF – What hard drive reliability really means

There is still no way around HDDs for the cost-effective provision of storage capacity. Different applications require the use of different HDDs. The decisive selection criteria are reliability and operating conditions.

HDD or SSD for storage systems? – Comparing the performance

One of the hottest topics within technology circles is when to move from established technology to the newer version, taking into account the costs and any possible risks. IT professionals are engaged in making this decision, determining whether (and when) SSDs offer better performance than the older, but lower cost, HDD technology. As one of the leading drive manufacturers with significant experience in both HDD and SSD technology, Toshiba Electronics Europe set out to investigate the question as to whether an array of 10krpm HDDs can offer a better performance solution than Enterprise SSDs and, if so, under what conditions?

Long term availability of replacement HDDs for enterprise storage systems

Modern hard drives, and especially enterprise hard drives, are inherently very reliable. Manufacturers such as Toshiba offer warranties of up to five years, which indicates their confidence in the products. Popular models such as Toshiba’s MG06 offer Mean Time To Failure (MTTF) figures of 2.5 million hours – a figure that has been increased from 2 million hours. In the real world, this means that in an installation of 1000 enterprise hard drives, users should expect only two or three drives to fail per year during the warranty period.

Which storage system: HDD or SSD?

The world of data storage is moving on quickly. We are creating more data than ever before, which has to be stored securely and should be easy to retrieve. A couple of decades ago tape was the preferred storage method and these days it is in fact still in use, but limited to very centralised archiving applications. The invention of disc drives based upon high-density spinning magnetic platters – now known as Hard Disc Drives (HDDs) brought higher storage densities and much greater user convenience, especially in terms of data accessibility.
