My first harddisk was a mere 40 Megabytes in the 90s. I used a AT-286 PC with DOS operating system (no windows yet). I couldn’t find a way to fill the harddisk as much as I want to. Bear in mind there was no MP3, No CDroms, and No digital camera yet.
As a couple years went by, I got a 486 with a 13 Gigabytes harddisk. Again, I had the same problem, I did not know what situation I would need all the storage offered by the harddisk. Before pentium started, MP3 started to make way into the Internet. My 486 struggled to play a MP3 music, I can’t touch the mouse or keyboard or run any applications while a MP3 music was played. If I did anything while listening to the music, the music played will be interrupted.
In early 2000, I bought a 120GB exteternal HDD from Iomega at a price about US$ 300. It was big and I like it. Within a year, it has filled with all my documents, photos, backups, etc. I purchased newly launched 250GB external HDD from iomega at early adopter price US$ 600. Can’t get enough and I bought 4 of those in the next 1-2 years time frame.
Storage prices kept falling down even now. It may be worth to purchase new storage then try to squeeze and clean-up the mess in the current HDD for weeks. Yesterday, I made a bold step by skipping a 1TB harddisk altogether and get 2 TeraBytes harddisk.
How big is 2 TB? Well, it’s about 2,000,000,000,000 Bytes/Characters. It’s about 500 times of my first harddisk (40MB) and 150 times of my second harddisk (13GB) and 8 times of my Iomega 250GB harddisk. Can you believe that? How much it cost me to get 2TB harddisk? Less than the price of 250GB Iomega harddisk I bought 3 years ago!!
Why would I need that massive amount of harddisk? Well, Photography using DSLR takes a lot of storage. One picture at 12Mpixel is sized about 10MB, while shooting in RAW (uncompressed photo) can takes 60 MB per photo.
Practical Advise:
- Storage price are falling and will keep falling. Buy what you need for short-term.
- Invest in a good harddisk brand with 3 or 5 years warranty. Trading a few dollars saving for shorter warranty period is not worth the saving.
- If you need USB interface only, you can get cheaper external harddisk. HDD sold at higher price usually include a firewire (needed when using MAC) or eSata. If you don’t need it, just for USB one if budget is a concern.
- Bigger storage translate to bigger increase of data corruption or failure. Buy a second harddisk to backup your important datas. Photos are one example where when lost can’t be recreated.
