In addition to the security and system updates released earlier today, Apple has firmware updaters available for iMac graphics as well as Apple RAID cards.… Read more
Adaptec has announced the immediate availability of a Series 5Z Unified Serial (SATA/SAS) RAID controller family with "Zero Maintenance Cache Protection." It's designed to replace the current generation of RAID controllers that use lithium ion batteries to protect data in cache memory.
This announcement is significant for two reasons. First, its shows the expanding role of NAND flash. Recently, NAND flash has been associated with the second coming of solid state disk (SSD) in enterprise disk arrays. In spite of reliability issues (the more flash memory is written to, the less reliable it becomes over time), … Read more
The basic idea of RAID (Redundant Array of Inexpensive Disks) storage is combining multiple small, cheap disk drives into an array of disk drives (appearing to the computer as a single logical storage unit) that yields performance exceeding that of a SLED (Single Large Expensive Drive).
RAID offers many advantages over the use of single hard disks, including higher data security, fault tolerance, improved availability, and integrated capacity.
That said, RAID was invented more than 30 years ago and simply wasn't designed to work in the terabyte system world that is commonplace today. In fact, RAID is clearly beyond … Read more
Basically, it lets you mix hard drives of any capacity together into a volume that's well-balanced between the largest possible amount of storage and maximum data redundancy. While the Drobo's performance didn't meet our expectations, its technology offers a lot of potential.
Data Robotics on Tuesday expanded that potential into an all new product for the business environment, the DroboPro.
This is the company's first foray into the business sector, and it calls the DroboPro the "business class storage array that manages itself."
Much like the Drobo, the DroboPro also allows for mixing hard drives of different capacities, and you can hot-swap any of them without having to restart or interrupt the data access. This translates into no-downtime expansion of the storage volume. Moreover, unlike the Drobo, the DroboPro now includes protection against multiple concurrent drive failures.
While the Drobo is a pure external direct attach storage (DAS) device with USB 2.0 and FireWire 800 connections, the DroboPro also includes the iSCSI interface (via a Gigabit Ethernet connection). This makes the DroboPro one of a few hybrid devices that support both network attached storage and DAS. As you need to buy the DroboShare to make the Drobo work with a network, personally, I think the addition of the network port is the most welcome feature of the DroboPro.… Read more
We're noticing more and more solid-state drives enter the mainstream market; the Intel X-25M drive's blazing fast transfer speed and completely unaffordable price tag felt bittersweet, but the prices aren't quite as bad for lesser quality drives like the Patriot Warp V.2. SSDs are popping up more often in the world of Netbooks, but we rarely see standalone external SSD.
Luckily, G-Technology made good use of this year's Macworld Expo by introducing a new family of external solid-state hard drives. Both the G-Drive mini SSD and the RAID 0/1 G-RAID mini SSD use 2.… Read more
We're coming to you from CES 2009 in Las Vegas, Nevada and it's all about Netbooks today. I'm sure we'll get more buzz about 3D TVs and more later this week. Also, Ellie doesn't like it when we call out the title of the show, but that makes it easier for Jason to find them for his special edition! (And please excuse a bit of distortion in today's episode. Sorry! -Jason) Listen now: Download today's podcastEPISODE 886

The new NAS server has four hard-drive bays: each can accommodate a 3.5-inch SATA internal hard drive up to 1TB in capacity, making the server's total storage space up to 4TB. The four hard drives can be installed or removed completely without using a tool and set up in RAID 0, RAID 1, or RAID 5 configurations. The NAS server … Read more
No moving parts, shock resistant, and incredibly short seek time are some of many benefits you get from a solid-state hard drive. However, for now, the price for a SSD is so incredibly high that calling "insanely priced" might not be an over statement. It's hard to justify (or to afford for that matter) spending about $1,000 for only 64GB when you can pay about 10 percent of that cost for a regular 200GB laptop hard drive.
So how about making our own SSD?Sans Digital just released the CR2T CompactFlash card enclosure that might make … Read more
No, I am not talking about something that's for or from an airplane. It's simply a network attached storage device from VOX. The full name--don't hold your breath, you've already read the creative part--is BlackBox Dual Bay Gigabit RAID Shared Network Storage. As if the naming it BlackBox were not sensational enough, VOX decided to paint the device silver.
Other than the confusing, yet very telling name, the device is actually straightforward. It's a dual bay NAS device that supports RAID 0 and RAID 1. It's always nice to have the option of using … Read more
Western Digital today added a new member to its My Book line of external hard drives. The My Book Mirror Edition is a USB-only, dual-drive unit with RAID 1 redundancy. The 1TB model costs $290, and the 2TB model costs $550. With your data mirrored on both drives, your total storage space is half the stated capacity. The My Book Mirror can be configured with RAID 0, should you want to make use of the full capacity of each drive.
The My Book Mirror's two hard drives are replaceable--no tools required. The drives feature Western Digital's GreenPower technology, … Read more
