Being a performance guy with the best in the world at my finger tips it's sometimes difficult to grasp the lower end of the market. Solid state drives deliver a different kind of performance that can't be achieved by upgrading your processor, video card or system memory. To put it bluntly, when it comes to overall performance and the user experience, there is nothing else on the market that can make your computer better than a solid state drive. This even holds true for older computers, if you have a SATA port then your computer will feel better than new simply by plugging in a SSD.
Solid state drive manufactures are aware of this too and are trying to make SSDs more accessible because they are truly the best bang for your buck upgrade. Obviously dropping in a $200 SSD is going to make your computer feel great, but in 2012 nearly the same user experience will be available for $60 and over time the cost will go down even more.
Still, there are some tradeoffs with the smaller drives, but you aren't going to notice them when coming from a platter drive. The difference between the 30GB and 60GB drives compared to the 120GB and 240GB models is still quite significant when measuring some of the performance metrics, but then again the price difference is also significant.
If you've been on the fence about purchasing a solid state drive it's time to hop off and get with the program. The ADATA S396 30GB drive has an MSRP of just $60 and will be a very good entry-level product for anyone on a tight budget. This drive delivers all the read and write access times that make SSDs great and gives you just enough capacity to install your OS, Office Suite and a few programs. For most users that is all you need. To top it off ADATA is giving you an excellent accessory package that you normally don't see with value drives.
