5. Read/Write Speed and Summary
The Mirror Edition’s speed test results indicate that enormous capacity has nothing to do with read and write speed for an external USB 2.0 storage device. This 2 TB managed to beat a 320 GB drive in read speed, but couldn’t surpass that same smaller drive’s write speed (we’re making a comparison to the Western Digital Extreme Lighted Combo drive) listed on our charts average read speed on the Mirror Edition was 34.8 Mbps in RAID 1 (the halved storage/mirror mode), and 35.9 Mbps in Raid 0, where the computer perceived the drive as one 2 TB drive. The Western Digital Extreme Lighted Combo tapped out at 31.0 Mbps.
The Mirror Edition write speed reached 20.1 Mbps in RAID 1, and matched that 20.1 Mbps in RAID 0. The Western Digital Extreme Lighted Combo drive reached 26.9 Mbps. The Mirror Edition’s write speed is on the slower end for USB 2.0 external drives, while it’s read speed is above average. If you use the Anywhere Backup software, however, these speeds don’t matter much since the backup takes place in the background and in idle moments.
Testing Score: 3.5/5 Summary: At $549.99 The WD My Book Mirror Edition is one of the cheapest 2 TB of external storage available. Buffalo Technology makes a 2 TB DriveStation with a slew of RAID and mirroring modes, but it sells for $799. LaCie makes a 2 TB Big Disk Extreme+ Dual with no mirroring modes, which sells for $619. There is no doubt that the Mirror Edition represents a good value: The price comes to 27.5 cents per gigabyte! But this bulk storage doesn’t have all possible bells and whistles. For a drive this big, mirroring is a nice luxury, but cuts the capacity in half. Yet, even a 1 TB drive merits a place on the network. The Mirror Edition would be ideal, though not nearly as cheap, if it came as NAS.

it's not called a drive...the drives are inside...it's called an "enclosure"
Actually, it is an external drive.
It looks like Morse code, and you can desipher letters in the plastic, but they read nothing (just two lines, read forwards and backwards) ETENESTT, TTSEANETE, EHSETENT, TAETESHE. In Morse code, some letters (like A and N) use the same digits, just backwards

Yeah, I know it's an external drive...the part you call the drive, in the article, as in, "handling the drive (moving it from place to place) and grasping the sides, the plastic walls creak a little bit and give slightly under pressure. You don’t want to stack anything on top of this drive.", is actually the "enclosure" or "housing"...as in ENCLOSING or HOUSING the drives.
Sure, I am nit picking, but say the drives are great and the electronics are fine, but the housing falls apart; you cannot then correctly state that the drive broke because the "drives" are still fine and would still work.
It’s tough to make a 2 TB external hard drive look cute.
from wikipedia:
http://en.wikipedia.org/wiki/Western_Digital_My_Book
The Morse Code message written into the drive case is made up of a selection of the words 'personal', 'reliable', 'innovative', 'simple', and 'design'.[15] The first occurrence of 'innovative' on the My Book Pro and My Book World Edition features an error and reads 'innovateve'.
I'm assuming they've kept the morse code message uniform throughout the mybook series.
royalcrown a word's meaning comes not from it's hard-line definition, but from how it's used by a majority of people. Language is not mathematics. Most people would call Western Digital's system here a 'drive'. They would not be wrong, and neither is Rachel, except in a technical sense. Calling it an 'enclosure' is not only incorrect in a technical sense it is incorrect in the way people speak; to most of us, 'enclosure' would mean something provided that you put things in to, not something that comes already filled.
If you want to nitpick then be right; Western digital calls it a system, and that's what it is - 2 hard drives in an enclosure with software and hardware so it can be used in a 'Raid 0 or 1' configuration. If you want to be right, technically, call it a 'hard drive system'. If you want to communicate correctly, then use the language people understand; most would call this device a 'drive' over an 'enclosure'. Western Digital calls it a 'System'. Since I like to be right technically and say things in a way most would understand, I'd call this thing an external hard drive backup system. Off the cuff, though, I'd call it a 'drive', certainly not an 'enclosure'.

It's not 2 1TB drives it's 2 2TB drives as with the mirror edition something gets copied onto 1 drive the "mirrored" on the other for data protection. Just thought I should clear that up. You may want to edit the article.
