1 Terabyte in only 7 milimeters


The trend of manufacturing thinner disks with larger capacity is continued by Western Digital with their launch of WD10SPCX. Disk enters the company's Blue product line and comes in 2.5-inch format suitable for notebooks.

Over the years the need for more storage has exploded. I have seen systems with 750GB drive packed with pictures, MP3s and movies not to mention actual work files. It has become borderline ridiculous. Still we need to have better access to more space to store our stuff. To help with this many companies have begun manufacturing network attached storage devices. These are multi-drive products that can be connected to a home or small business network and used as a central spot for file storage. We have covered a couple of them and have a few more to show you in the future. The problem with many of these is that to keep costs down they are often shipped without drives. Many think that they can just buy a bunch of drives of the same size and throw them in. That does not always work though; we have run into a few cases where the NAS device did not work with a single range of drives or need a certain firmware revision to work with the drives. It becomes a frustrating game of finding the right drives to work with your NAS and also to get the best performance out of it. To help with this Western Digital have come up with a line of disk drives that are designed specifically to work with NAS devices. These are their new WD Red Drives. The WD Red Drives will come in 1-3TB sizes and should fall into line between the WD Green and Black Drives in terms of performance and price. Western Digital has sent us three of their WD Red 2TB drives for us to try out in two of the NAS devices we have here, so let’s see how they do.

IBM builds largest disk array ever

Hard-Disk-Drive-1There is RAID and then there is RAID!. Well IBM has the latter that is a conglomerate of 200,000 disk drives combined together to make up a 120 Petabyte (not to be confused with Pedabite which has to do with chewing on feet) drive array. IBM built this to accumulate data for weather simulations. We imagine that these would be more than answering what the temp will be on Monday but will likely be for long-term forecast models and of course everyone favorite; global warming.

The array is going to an as yet unnamed client of IBM’s but IBM did say that one day (in the far far future maybe) cloud systems would all have similar storage arrays. For those interested this is not a giant JBOD or even RAID 50 array. This is something new called GPFS that allows the system to almost self-heal. If a single disk begins to fail the system can move the data slowly to a ready spare without the normal rebuild times you expect from other arrays. It can also spread files across multiple disks allow extremely fast read/write/index times.

I wonder if I can put something like this together in the garage…
