well entropy while your insight is noted the vertex 3 is still $200 not $150 user stated $150 price limit
Force GT over Force 3 is massive price bump at 90gb
and does asynchronus matter? no not really the speed of any SSD is to the point you wont feel or ever notice the difference between them mostly because there response is in the sub millisecond vs 14-18ms of an HDD per item read,
how about recommending SSD's that fit the OPs price limit that would be a good start would it not
while I agree that Vertex 3 and Force GT are better SSDs there not good enough to warrant the far higher price tag
show me in real usage in daily tasks where the extra $50-70 gets you a boost worth paying for.
if you absolutely must have performance lower capacity higher speeds is great but id recommend the extra storage space simply do to the fact over time youll want that extra space,
