I got an SSD (Solid State Drive) for a laptop early last year. I noticed the overwhelming speed experience and became a fan. Today, after installing it on my own laptop, I noticed that in addition to the speed, the battery life’s now extended by a whopping 2 hours or more!
Yes, you can buy a massive internal drive for the price of a 128 or 256 GB SSD. I think the time and energy savings of buying a smaller SSD are worth it, unless you’re doing massive video edits or dealing with larger files. In that case you might just want to splurge on a larger SSD.
If you’re in India, I can say that the SanDisk X21 is a steal. I’ve tried Samsung’s EVO and they’re awesome – but they’re consumer SSDs. The X21 is targeted at the OEM (Original Equipment Manufacturer) market, and low end server market. So you won’t get a fancy box, or the software to help transfer your current hard drive over, but you’ll get a great bargain for the price and something that’s going to last you a long while!
