Solid state drives set for huge growth Enterprise solid state drive (SSD) sales will grow by almost 90 per cent a year between now and 2015. The prediction covers flash-based solid-state drives (SSDs) in enterprise servers and SANs (storage area networks). The main forecasts are that the market for enterprise SSDs will grow from 150,000 units in 2010 to over 4.1 …
So soon, we 're going to run out of flash chips . and we'll have a shock rise in flash prices,
followed by a massive investment in fabs, followed by a serious over supply by 2015
and then cheap flash based SSD's will become available and standard.
I've never seen this sort of cycle before !
Can't believe they are keeping prices as high as they are. I have 2TB of HDD space in my PC which I would replace with SSD *today* if I could get it for £150 or less. But at the current silly prices of a small defence budget per byte their market is *GOING* to stay tiny. Simply ramp up production - whatever that takes, and I would recommend such a switch to *everyone* I know. Multiply that by all the geeks on the planet and you have an instant market of trillions (and I mean proper British trillions, not those namby pamby US trillions where 1tr=about 3 and a half).
These analyst estimates seem extremely optimistic.
Most applications and databases cannot fully take advantage of the speed promised by flash-based SSD due to bottlenecking somewhere-- usually code efficiency but sometimes CPU or memory. (Memory bottlenecking is common for 32 bit apps.) It takes time to recode things, especially when you're waiting on a vendor to do it.
15k drives will be marginalized, but 7.2k SATA drives are going to be around for long after SSD goes mainstream.

This is an InnoDB strap-on to MySQL that was written with SSD-based storage in mind. Therefore, "It takes time to recode things, especially when you're waiting on a vendor to do it." only applies to proprietary vendors, or FOSS that has a marginal community around it. :)
In addition to Colin_L's comments, there is also the issue of not being able to trust SSDs when they say that they have committed data.
Documentation from vendors is very vague, and certainly at the advertised write speeds there's a little fibbing going off.
Once we know the operating systems fsync/datasync etc works reliably then maybe...
Not quite sure what you're getting on at. It's already possible to buy 512GB SSDs in a 2.5" form factor, so we could jsut take 4 of those and still be smaller than a 3.5" drive... and we can do it today.
As a matter of fact you could fit 6x 512GB SSDs into the space a single 2TB 3.5" drive takes up.
cost is another matter...
