Two startups making waves in the solid state storage market are talking money today. As Dean Takahashi over at VentureBeat reports, Violin Memory has closed a Series C investment round for $40Million, valuing the company at $440Million. Elsewhere, Leena Rao at TechCrunch notes suggests that Fusion IO has upped their pre-IPO price from $16 to $18 per share; valuing the company at a notional $1.4Billion. When Fusion announced their IPO back in March, Stacey Higginbotham suggested that the company was fishing for a buyer, but no one seems to have jumped (in public, at least) yet. Time is running out, and the price would appear to be heading upward. As Arik Hesseldahl notes at AllThings D, although the two companies are involved with solid state storage, they’re tackling different problems; “Where Fusion-io sells flash-based cards that make servers run faster… Violin sells flash-based memory arrays that are intended to replace the hard disk-based memory arrays that make enterprise applications run faster.” Flash, it would appear, remains hot.
