WD’s 1 TB Laptop Drive? Not Quite!

July 27, 2009 by Stephen 3 Comments

Western Digital announced this morning the world’s first “1 TB mobile hard drive!” But although the news is great for storage-hungry folks looking for a portable external drive, it doesn’t quite mark a sea change in the storage industry since this drive cannot be used in (most) laptops.

Specialized Server/Enterprise Hard Drives

August 7, 2007 by Stephen 3 Comments

Continuing my overview of the specialized hard drive market, we move on to the world of enterprise hard disk drives. These are performance monsters, with nearly all falling above the 10,000 RPM line that defines “exotic” in the desktop space. They also have a wide variety of interfaces, including parallel and serial SCSI, Fibre Channel, […]

Specialized Hard Drives: Worth the Effort?

August 3, 2007 by Stephen 2 Comments

Lately, there has been a lot of buzz in the enterprise storage arena about whether so-called “enterprise drives” are really any better than plain-Jane hard drives in Enterprise applications. This came to a head with the controversial findings of Google and CMU, but it’s been simmering under the covers everywhere from TiVo communities to gamers. […]

GPS Time Rollover Failures Keep Happening (But They’re Almost Done)

This is week “1111111111” in the GPS system. Tomorrow morning it will roll over to week “0000000000”. How well will various systems handle this change? Not well, judging by what we’ve seen so far!

Ranting and Raving About the 2018 iPad Pro

I remain enthusiastic about the iPad Pro, despite getting a scratched screen and my concerns about durability. It’s a worthy successor to the original and offers enough improvements that I’d recommend the upgrade for just about anyone who uses their iPad for serious work. It’s still not yet a laptop replacement, but this is due more to a lack of desktop-class software for iOS than anything in Apple’s control.

The I/O Blender Part 1: Ye Olde Storage I/O Path

May 23, 2012

This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.

My Visit to Bletchley Park

August 3, 2012

Bletchley Park is much more than a museum. For those interested in the history of computing, like me, or World War II buffs, it’s a must-see. The reconstructed Bombe and Colossus computer are truly breathtaking, and I find myself drawn to the stories of codebreaking that took place here. I highly recommend a visit!

Begun, the Patent Wars Have

July 9, 2012

Every day, it seems there is a new lawsuit in the mobile phone industry. HTC, Motorola, Google, Microsoft, and especially Apple and Samsung are actively litigating their way through a thicket of patents. The same is increasingly happening in the rest of the IT industry. But is all this bloodshed really about innovation? Or is it, as one federal judge noted, simply a new form of intense business competition?

Deduplication Coming to Primary Storage

September 16, 2008

Although deduplication of storage is nothing new, with Data Domain and other making hay with the technique for years, it has never been ready for prime time – reduction of active primary storage applications like email and databases. Instead, deduplication has been relegated to second- or third-tier status, deduplicating archives and backup data. But change is in the air, and deduplication vendors are starting to bustle towards the bright lights of primary storage.

Why Big Disk Drives Require Data Integrity Checking

December 19, 2014

Hard disk drives keep getting bigger, meaning capacity just keeps getting cheaper. But storage capacity is like money: The more you have, the more you use. And this growth in capacity means that data is at risk from a very old nemesis: Unrecoverable Read Errors (URE).

It’s Fine To Mount Hard Drives On Their Side Or Even Upside-Down

August 13, 2016

Have you ever wondered if mounting a hard disk drive on its side or even upside-down affects its lifespan or reliability? According to every drive manufacturer, it’s perfectly acceptable to mount a hard disk drive in any orientation as long as it’s not tilted and has sufficient cooling.

The Four Horsemen of Storage System Performance: The Rule of Spindles

August 25, 2010

Why do some data storage solutions perform better than others? Mechanical performance, RAM caching, I/O capacity, and the intelligence of the system all have a part to play. Today we examine the rule of spindles: Adding more disk spindles is generally more effective than using faster spindles.

Here’s Something Your Raspberry Pi Can’t Do: Gigabit Ethernet and SATA in the Olimex A20-OLinuXIno-LIME2

May 25, 2016

I’ve really enjoyed experimenting with the Raspberry Pi, and have even deployed a few as UNIX servers in my home and office network. The quad-core performance of the latest Pi models is awesome, but serious I/O limitations remain. With just one USB 2.0 interface shared for all network and storage operations, you aren’t going to […]
