HDD vs. SSD – which lasts longer?

Many comparisons can be made between a Hard Disk Drive (HDD) and a Solid State Drive (SSD); cost, speed, data storage capacity – there’s no end of areas to consider. However in this post, we’ll be looking specifically at the durability of HDDs and SSDs to assess if there is any difference in life expectancy between the two data storage types. Physical failures It’s important to firstly note that any …Read More

SSD Technology and Lifecycle

With Flash Memory Summit approaching next week, I thought it would be a good time to dig into the technology and lifecycle of the SSD.  Unlike traditional hard drives, data in SSDs are not stored on a magnetic surface but inside of flash memory chips (NAND flash). By design, an SSD is made by a motherboard, a few memory chips (depending on the size in GB of the drive) and …Read More

SSD Survey Reveals…

Recently, Kroll Ontrack conducted a survey of consumers and businesses using SSDs and reconfirmed that SSDs are not immune to data loss, just like all media types. About 30% of respondents have experienced an issue with their SSDs. Of that 30%, over half (61%) experienced data loss and fewer than 20% were successful in recovering that lost data. When it comes to SSD technology there is some added complexity in …Read More

SSD Market – The Gathering

There can be only one! Ok, so the SSD market certainly will not consolidate to one company, but we are seeing a lot of movement.  One company acquiring the next in order to gain all of their wisdom and power.  Hopefully, not using the same methods as Connor MacLeod did in the Highlander films. This is not the first time consolidation has happened in the storage device market. We’ve seen …Read More

SSD Trends and Predictions

It’s been quite an eventful past year (2013) for SSDs. Here’s a quick recap of some of the observations we made at Kroll Ontrack: Sales of SSD and other flash devices increase as prices continue to decrease (storage capacity increased) and aligns more closely with HDD Kroll Ontrack has seen flash media recoveries grow to nearly 10% of all our recoveries this year. Ontrack Data Recovery engineers were challenged with …Read More

SSDs: Flash Technology with Risks and Side-Effects

SSDs (Solid State Drives) are now used as storage media in business almost everywhere. According to a new survey conducted by Kroll Ontrack, a specialist in data recovery, IT departments are still challenged by error rates, data recovery and secure data destruction. The results showed that 91% of the companies surveyed deploy SSDs, mostly on the client side (i.e. in desktop PCs and laptops). The survey further found that 51% of companies had to replace …Read More

SSD vs. HDD – Minimizing the Risk of Data Loss

This post is a continuation of the series on Solid State Drives (SSDs) and their role in enterprise storage.  In the first post, I discussed the differences between traditional HDDs and SSDs.  In the second post, I looked at the challenges associated with data destruction and asset disposal. In this post, I will discuss: How to minimize risks associated with data loss How to minimize risks associated with data destruction. …Read More

SSD vs. HDD – Data Destruction and Asset Disposal

Why care about data destruction and asset disposal?  According to the US Department of Commerce, data security breaches cost US companies more than $250 billion per year!  A few examples will help illustrate the importance of proper data erasure and asset disposal practices.  A Loyola University (Chicago) computer with the Social Security numbers of 5,800 students was discarded before its hard drive was erased, forcing the school to warn students …Read More

SSD vs. HDD – The Missing Considerations

Recently, there has been a lot written about Solid State Drives (SSDs) and their role in enterprise storage. These articles include several comparisons of solid state drives and mechanical drives in RAID arrays for enterprise applications. While most of these articles address several very key areas of comparison (cost, performance, capacity, power, cooling, reliability), they often neglect to consider data recovery and data destruction/asset disposal.  In the first part of …Read More

Live Server Erasure – How to Erase Data From a Running Server

Securely erasing data is definitely not an easy task. Whether it’s a single hard disk drive or a SSD in a laptop or many enterprise class storage devices inside a live server – just pressing the delete button on the keyboard just won´t cut it. As we have pointed out in previous blog posts, using the “Recycle Bin” and deleting a file is not enough. The same is true with …Read More
