Storage Special: Personal Storage
Storage gets portable
The personal storage market is in flux. Several
exciting options have been launched in the market, including pen
drivers and DVD writers, but consumers are slow to respond, says
Prashant L Rao. Once PCs with USB drives account for the bulk of
the installed base of computers, that too will change

| Dual writers that write to both the ‘+’
and ‘-’ formats of DVD media are expected to be the product
of choice soon for PC users who want to stack huge amounts of
data on a single DVD disc, says Sanjeev Gupta |
There was a time when personal storage used
to mean your PC’s hard drive and a box of floppies. Those days are
gone. Today you have a profusion of choices when it comes to storing
your documents and taking them along with you.
Personal storage II—USB drives
and DVD writers
The latest gizmos to hit the
personal storage scene are as different as fish and fowl. USB flash
memory drives (aka pen drives) plug into a computer’s USB port to
offer 32 to 256 MB of storage. Sony’s Microvault is a pocket-sized
flash memory device that works with USB 1.1 and USB 2.
With digital gadgets such as
digicams and handycams slowly moving into the mainstream, the future
is bright for compact storage. R Manikandan, LG Electronics India’s
DGM for sales & marketing of IT products says, "I feel
it [the growing popularity of digital gadgets] will lead to a proliferation
of compact storage options, since these activities will lead to
a lot of data being generated, ultimately requiring storage capacity."
The other newcomer on the storage
block is the DVD writer. It’s great for archiving your data with
4.7 GB of space on each DVD. DVD writers are a nascent format; as
of now they come with middling speeds and relatively high prices.
That’ll change by year-end as DVD writers move into the mainstream.
Carry that data
CD-R discs are the best way
to take your data around. CD writers are cheap (approximately Rs
3,000) and CD-ROM drives (that read discs burned on CD writers)
are ubiquitous. Best of all, today you can burn an entire disc in
a few minutes. That said, the 700 MB capacity of a CD-R/RW disc
isn’t quite enough for doing a one-click backup of your entire hard
drive, but it can be very useful for carrying your documents around.
In your pocket
In terms of being compact and
offering sufficient storage capacity, USB flash drives are amazing.
Unfortunately, these devices are yet to catch on in a big way. The
primary deterrent is the lack of USB support on PCs sold before
2000-01. Expect these drives to start gaining ground when the number
of USB-ready PCs starts to account for a significant proportion
of the market. PCs shipped in the last few years qualify but a lot
of PCs in India are four to six years old and they don’t work with
USB devices.
While the growth of newfangled
storage gadgets is driven in part by the proliferation of digital
cameras and handycams, demand for such devices hasn’t caught up.
Ashish Gupta, product manager,
Optical Media Storage at Samsung India says, "Digicams and
digital storage are not mass products [yet]. Globally we sell pen
drives but we are yet to launch the product in India."
On a DVD
DVD writers are the ideal solution
but as DVD-ROM drives needed for reading DVD (+-) RW discs aren’t
anywhere as popular as CD-ROM drives. DVD remains the portable storage
medium of the future with limited popularity for now.
Back it up
Backing up even a 20 GB hard
drive is no joke, as capacities have doubled and will soon quadruple.
While tape is the backup medium of choice for enterprises, personal
backup has traditionally been limited to floppies and, of late,
CD-Rs. Unfortunately, you have to spend a considerable amount of
time just figuring out what to backup and what to leave behind as
there’s a substantial mismatch between the size of your hard disk
and what fits onto a CD-R (700 MB). You’ll need dozens of CD-Rs
if you decide to backup your entire hard disk. Most of us opt to
pick and choose, which in turn leads us to take backups on an infrequent
basis. That’s a recipe for disaster.
A potential solution to this
messy problem is the DVD writer. While the models on sale carry
hefty price tags (Rs 13,500 to Rs 16,500), prices should drop significantly
in the next six to nine months. DVD standards are yet to be consolidated.
Pundits expect this to take place by end-2003. "DVD standards
are ambiguous. There’s still the split between the plus and minus
camps. We expect consolidation to take place by year end,"
says Gupta. By December, drives with the ability to read both the
plus and minus standards should be commonplace.
Iomega recently launched a
4x dual format drive that reads and records onto CD-R or RW, DVD+RW
and DVD-RW, in addition to reading DVD-ROM and CD-ROMs. "Dual
writers that write to both the ‘+’ and ‘-’ formats of DVD media
are expected to be the product of choice soon for PC users who want
to stack a huge amount of data on a single DVD disc," says
Sanjeev Gupta, senior manager for Business Development, Iomega Pacific.
"DVD-R is increasingly
getting accepted," says Manikandan. LG’s latest DVD writers
support multiple formats. Manikandan believes that one of the major
factors limiting the growth of the DVD market is DVD media pricing.
The nature of DVD usage is another bugbear. DVDs are equated with
entertainment in India, storage on DVD hasn’t picked up due to the
high cost of DVD-R discs. "The day DVDs are used for storage,
the market would surely pick up," adds Manikandan.
DVD writers are available at
both 2x and 4x write speeds. At 2.7 Mbps the write speed of a DVD
2x drive is a far cry from the CD 2x speed (300 Kbps). Still, using
a 2x DVD writer means a wait of half an hour to burn a DVD-R disc.
Though a 4x drive can burn a DVD-R in fifteen minutes, that’s still
a fair bit of time when compared to the couple of minutes you spend
burning a CD-R on a 40x or faster CD writer (the latest ones work
at 52x).
Through the crystal ball
Speeds need to pick up before
DVD writers become a mass option. That will happen in the medium
term and eventually DVD writers will replace CD writers as the best
option for personal data backup.
Don’t expect a DVD writer with
your new PC anytime soon though. The chances of even CD writers
or combo drives (DVD-ROM/CD-R/RW) becoming standard equipment on
branded PCs by end-2003 are slim. "With reducing prices and
need for more storage, these options will have higher attach rates
with [new] PCs, but the possibility of these becoming standard by
the end of this year is not seen," says Gupta.
Pen drives could replace floppies
but it will take time. Floppies have survived far too many so called
‘killers’ to be written off. They’re cheap, a box of ten can be
got for Rs 130 and, for documents, they’re good enough. The convenience
of copying entire directories en masse onto a USB flash device can’t
be denied, however.
Hard drives will continue to
get bigger offering more GB for your rupee. 40 GB hard drives are
standard issue with new PCs this year. By year-end that’s expected
to double to 80 GB. While much hype has been generated about MP3s
and videos, with the pathetic state of Net connectivity in the country,
most of us are going to end up filling our hard disks with applications.
Data’s still going to be a few megabytes at most, unless you’re
editing multimedia files on your PC. In a couple of years, USB should
be the norm and then it could be bye, bye floppy, but don’t hold
your breath waiting.

There are six recordable versions
of DVD-ROM: DVD-R for General, DVD-R for Authoring, DVD-RAM,
DVD-RW, DVD+RW, and DVD+R. DVD-R and DVD+R can record data
once, like CD-R, while DVD-RAM, DVD-RW, and DVD+RW can be
rewritten thousands of times, like CD-RW. DVD-R was first
available in fall 1997. DVD-RAM followed in summer 1998. DVD-RW
came out in Japan in December 1999, but was not available
in the US until spring 2001. DVD+RW became available in fall
2001. DVD+R was released in mid 2002.
Recordable
DVD was first available for use on computers only. Home DVD
video recorders (see 1.14) appeared worldwide in 2000. This
FAQ uses the terms drive and video recorder
to distinguish between recordable computer drives and home
set-top recorders.
DVD-RAM is more of a removable
storage device for computers than a video-recording format,
although it has become widely used in DVD video recorders
because of the flexibility it provides in editing and recording.
The other two recordable format families (DVD-R/RW and DVD+R/RW)
are essentially in competition with each other. The market
will determine which of them succeeds or if they end up coexisting
or merging. There are many claims that one or the other format
is better, but they are actually very similar. In 2003, many
companies began making drives that could record in both dash
and plus format.

| Two years ago IBM announced pixie
dust. Big Blue achieved a breakthrough in storage density
and succeeded in packing more data onto the same area by sandwiching
a three-atom-thick layer of ruthenium, a precious metal, between
two magnetic layers of antiferromagnetically-coupled media.
The big thing here was that only a few atoms were used, which
is why IBM scientists informally call the ruthenium layer pixie
dust. Building on that, IBM introduced the worlds highest
capacity mobile hard disk drive at 80 GB in 2002. This time
around, it enhanced pixie dust technology, in the process boosting
storage density by 100 percent, allowing up to 70 billion bits
of data to be written on each square inch of disk space. To
do this, the companys scientists added another coating
of pixie dust, an additional ruthenium/magnetic layer, to create
a five-layer sandwich called laminated-pixie dust, improving
the signal-to-noise ratio, allowing data recording at ultra
high densities without compromising on data integrity. IBM plans
to hit 100 gigabits/square inch this year. |
