While an interesting article, this really doesn't say to me "I need to upgrade my users to SSDs instead of HDDs". Why? Because alot of what is in the article doesn't apply firstly: We don't allow torrents of any kind (don't know of anyone in my type of business that does), people aren't permitted to download music, videos, etc.., all websurfing is controlled and monitored. Normal users aren't "encoding, compressing...etc...". Of course we have a small subset of people that need performance based equipment, however that is a really small subset of people.
Most people open outlook and leave it open all day long. They aren't opening and closing 20 different things. They work on a document, briefing, etc.. for hours at a time. I can't justify the expenditure for such a small gain in "performance" not productivity.
I have 1500PCs, at an extra $150 per machine (I wouldn't consider any SSD under 128GB for flexibiltiy purposes), that would equate to an additional $2.25 Mil on my "system refresh" projections. It just doesn't make business sense.
People can "boot" up faster? We don't let people "shutdown" in most cases, most of the time we operate 24/7.. We already control all startup programs etc...
Not to mention most places, mine included aren't replacing drives within machines, we select what we desire at time of "system refresh" to make things like support/replacement the easiest transactions possible. Now if 128GB (I'd rather have 300GB+) or higher SSDs are offered at the same price point as say 500GB standard HDDs then we would consider it. The dollar is what matters in most cases, and normal office apps simply don't tax systems enough to make much of a difference.
