Here are the top SSD 2012 stories and trends:
All-flash arrays no longer an oddity
So far it's been a field dominated by startups, but all-flash arrays proliferated in 2012. By the end of the year, Nimbus Data, Violin Memory, Pure Storage, SolidFire, Kaminario, Whiptail, Tegile Systems and Skyera had all-flash arrays on the market.
And the large vendors are also jumping in. IBM acquired Texas Memory Systems and EMC bought in-stealth XtremeIO in two of the largest storage acquisitions in 2012. NetApp and Hitachi Data Systems are planning all-flash arrays, and Hewlett-Packard sells all-flash versions of its StoreServ (3PAR) and StoreVirtual (LeftHand) arrays.

MLC flash elbows into the enterprise
The trend of multi-level cell (MLC) and enterprise MLC (eMLC) in data center storage began in 2011, but became a full-blown movement in 2012. Solid-state drive (SSD) vendors turned to MLC and eMLC to try and overcome the biggest obstacle facing enterprise flash adoption -- price.
More expensive single-level cell (SLC) flash still has its place in use cases where long-term reliability is a must-have, but eMLC and consumer-grade MLC flash are now the standard flash components in all-flash arrays and in hybrids.

Storage vendors embrace server-based flash
EMC added its VFCache server-based flash caching product this year, and NetApp is following with Flash Accel software. These products piggy-back the success of PCIe-based flash vendor Fusion-io, which scored a reseller deal with NetApp in 2012. EMC chose Micron and LSI as its VFCache partners.
With server-side flash competition heating up, the PCIe solid-state card vendors and software startups are adding software management and caching applications. And host bus adapter (HBA) vendor QLogic got into the flash game with its Mt. Rainier card.

Brute performance no longer enough, enterprise features also needed
As the solid-state storage market matures, vendors are differentiating their products to gain footholds in various vertical markets and use cases. SolidFire targets service providers with guaranteed Quality of Service (QoS) software in multi-tenant environments, while Nexgen Storage Inc. hybrid arrays use QoS to target the midmarket.
All-flash vendors whose products are past the first generation are adding typical enterprise features such as advanced data protection, and high availability. Snapshots, replication and thin provisioning are among the features enterprise storage administrators will demand to implement solid-state arrays in the data center.

VDI drives flash adoption
Because it is IOPS- and read-intensive, virtual desktop infrastructure (VDI) is an early killer app for solid-state storage. Companies are turning to hybrid and all-flash systems to rescue VDI projects that had stalled because of poor storage performance, and vendors are seeing a spike in adoption.
