DVR and Home PC Hard Drives
So who can name a few hard drive manufacturers? Hitachi, Seagate, Western Digital… I remember, 80 GB hard drives, then 120′s and now we toss around words like, 1 Terabyte and 2 Terabytes as if they should be standard already in nearly every piece of electronics we buy. So are all hard drives made the same? Why do some companies use one over the other and whats up with a compatibility list?
Let’s start with Enterprise and Desk-top class hard drives. We have many customers who often have some spare hard drive laying around their home and want to put it to use. So when they come in to one of our stores to purchase a shiny new recorder for their home surveillance system, we offer them 3 choices in terms of hard drive capacity.
“But what about that hard drive I have at home, can’t I just use that one?”
So we ask a few simple questions of our own. Do you have the model number so I can see if the compatibility list has it on there? What size hard drive is it? Is it IDE or Sata? What usually follows after we ask is…
“So what hard drive sizes do I get to choose from?”
We use Enterprise class hard drives for our DVR’s they are designed to be running 24/7 and to be written too far more often than a home PC. They also have a higher heat tolerance and it’s faster to access data from them. They may be a bit more costly over a PC hard drive but remember, they each serve different purposes. Having a more sturdy storage disk that is designed to reduce and/or correct its own internal disk errors, is by far what you’d want in terms of what to store your video on.
A home PC hard drive is designed to run 8hrs a day 5 days a week. When you keep to these basics you can get longevity out of it. However if it is not your recorder for your camera system, there’s not really a big need to rush out and get an Enterprise class drive for it.
When it comes to storage for your Digital Video Recorder, stick to what’s best and been tested for the one you choose. Avoid just tossing any spare components into a piece of equipment that you intend to rely on for home protection. The extra coin you spend on something like this may one day be well worth it.
