Old Storage, New To You: It’s Time To Consider Buying Refurbished Hard Drives

For the entirety of my time buying drives, going back many years, I’ve bought only new hard drives. For my servers, I’ve tried to buy NAS grade drives. NAS drives, compared to a desktop drive, are rated for more continuous operation and load.

But, my redundant backup strategy can be expensive, so while my NAS is using NAS drives I bought new, I decided for one of my two redundant backup locations, I’d try a pair of refurbished drives. I went with an outlet called Goharddrive. They sell through Amazon, eBay, Newegg, etc. Another called Serverpartdeals seems to have good reviews overall, through multiple sources.

From what my research seems to indicate, these two at least have good reputations for offering items that are not likely to fail quickly, and if they do, they quickly honor their five year warranty. Seagate and Western Digital have cut back the warranty period on some drives to 3 years, but still offer some drives at the 5 year mark. So, these refurbished drives, even if they fail, will be replaced during that period. They are designed for high data use as they were likely pulled out of data centers and other enterprise uses.

There are definitely advantages to these refurbished drives even for a primary function. But the lesson is, you shouldn’t use a refurbished drive without redundancy. But the same applies to new drives. New drives may last less time than a refurbished one, or more. So, the lesson in the end is to make sure that you never rely on a single drive regardless.

Here’s a link to a 10TB hard drive sold by Goharddrive via Amazon. A similar new NAS drive is running over double that. Assuming you get 3-5 years out of it, which is guaranteed, you may be taking a risk, but its an acceptable one. So, it’s perfect for sending my files to from my primary NAS, and will sit at a family member’s home as a backup server. Definitely cheaper than the cloud.

Thinking about RAID vs Backup

Six hard disk drives with cases opened showing...

The cost of storage hit a low the last time it was time for a storage upgrade. Then prices shot through the roof after a flood in Thailand closed factories.

This shut down all of my hard drives purchases for over two years. When I emerged from my cocoon, Samsung was gone as a Hard Drive manufacturer…and I had bought many Samsung OEM hard drives.

The purpose of RAID in a redundant system is to protect against hardware failure. You have different levels of RAID for this, RAID 1 for just a straight mirror, and RAID 5 and 6, which involve a minimum of 3-4 drives to accomplish.

RAID is important if you care about uptime. If you can afford to be down for a bit, backups are a better choice.

What is being stored, in this case, consists of several categories: Video, Music, Documents, Configuration Files. There is no point in storing complete drive images. The OS can be reinstalled, and it probably will be better off and cleaner running after it is. The OS drive on all of the systems I’ve built or refurbed in the last two years is an SSD, which is a common practice nowadays.

I had been mulling this after reading an article on another hardware refresh by Adam Williamson. He hadn’t refreshed in seven and a half years and used a separate NAS and server. So, why refresh after only two and a half years? Partly it was due to mistakes.

I’d been using WD Green drives. These had several limitations. They park the head after only 8 seconds of inactivity, which increased the load cycle count. The WD Red Drive is designed for 24/7 operation in network attached storage, with a longer warranty, and I now have two 3TB drives. The only other alternative in WD’s stable was a Black drive, their performance drive. It might be time to consider a Seagate, the main competitor, as well.

The warranty situation in hard drives now continues to drop. Five years, down to thee, and down to two years. So there is less protection from the manufacturer and less inclination to create quality products. That was why we were buying OEM over Consumer Drives over the last few years.

Back to the subject at hand…why not a RAID? It is simply a matter of cost vs. benefit. This is terabytes of video data, mostly a DVD archive I intend to create by backing up my DVD collection to MKV. If it were lost, the original copies aren’t going anywhere. But, more importantly, cloud backup is impractical.

Using Amazon S3, for example, at a rate of 9.5 cents a GB, that is just under $100 a month per TB. Amazon Glacier, which is their long-term backup option, is 1 cent a GB, or roughly $10 a TB. But once you take video out of the equation, or sharply reduce it, budgeting $5 a month for important data is a reasonable amount, and still gets you a lot of storage options to work with.

So, to ensure redundancy, there is a second drive in the system, and backups will be done to it. From there, the backups of everything but the video store will be sent up to the cloud. As I’ve mostly given up buying DVDs(due to Blu-Ray), the collection should be fairly static.

Back to Adam Williamson, he had a great idea of having the other computers on the network back up their data to the server, independently isolated by each machine having a separate user account on the server. Not quite there yet, but sounds good. I have other plans to download data from my cloud service providers(Google, Dropbox, etc., and maintain a local backup, but that is a longer-term project. I’m reasonably certain in the interim, Google has a better backup system then I do.

What about off-site then? I still have the old 1TB Green Drives. They can be run through diagnostics, loaded up as a backup, and sent off to a relative’s house…I’ve added a hard drive dock through an E-SATA port to support this.

So in the end, RAID wasn’t necessary for me, but some redundancy was. It may be for you. Comments?

More to come…

Wakeup for HTPCs and Servers

A remote control's infrared seen as near-infra...

Tonight, we upgraded an old computer we use as a secondary MythTV combined backend and a frontend. It is currently the only computer we use ACPI Wakeup on, so we spent some time resetting this feature.

There are three basic Wakeup Types that are useful for computers nowadays.

  • Wake on LAN – Wake the computer up in response to a signal over the network.
  • Wake on USB – Wake the computer up in response to a USB signal
  • Wake on Alarm – Set a time for the computer to wake up

So, how can we leverage this into power-savings and efficiency? By having the computer turn itself off when it isn’t in use. We’ve been using it in cooperation with our TV recording schedule. Computer starts up, records, sets a wakeup for the next time, then shuts down.

But after that, what can we do with this? Wake on LAN allows the computer to be tripped into an active state over a network. Wake on USB would allow us to activate the computer with a USB remote control or other USB communications device, such as a sensor.

The feature is built into every current computer. So, why around we using it? We didn’t even get to the discussion of Suspend to RAM and Hibernate, two features that either save the system state to the hard drive or keep the system on minimal power to keep data in the RAM, which offer additional options.

So, why aren’t you using the power-saving functions of your computer?

Western Digital Unveils Two New Media Options

The WD Media Player is a great device in both price and features. It plays almost any file off of a USB-connected flash or hard drive.

Details have been leaked of the next generation WD-TV-2, which adds a network connection for streaming video from a network connected drive. This device could replace the old computers we currently have connected to some televisions for easy media playback from our network server, although we may hold out for an Ion computer. Either way, it looks like a good update. More to come as details are available.

Western Digital has also added a discount option. The WD TV Mini. It is smaller than the current box and loses HDMI and full 1080p in favor of analog HD and SD outputs only.
