[citation][nom]tayb[/nom]Show me someone who would rather have a 128GB Solid State Drive instead of a 400GB WD Hard Drive and I'll show you someone with more money than brains.[/citation]
Sure, if all you want is capacity, then it's actually better to buy a 1.5TB for $139.00 (9.2cents/GB). But, if I want value and low power for my IOPS, I'd rather buy an SSD. The 256GB version of this drive has a price of $645.00. That's a painful $2.50 / GB but only .05 to .10 cents per IOP (seq. vs. random write). Not bad at all. It would take many WD drives and lots of power to get these kinds of IOPS .... and most importantly, all those drives will not fit in my laptop 🙂
$2.50 / GB (ouch!)
but:
$0.50 / IOP (not too shabby)
