Found this today, dunno if it's a great deal but certainly a good deal at nearly 40-50% off list.
HGST STEC Zeusram SSD 8GB SAS Enterprise Class New Zeus RAM | eBay
I have one of these on my AIO vSphere/Omni/ZFS array and it is the single saving grace on my stripped mirror (ZFS raid10) 6 disk Hitachi Ultrastar pool for NFS VM's. Running 30+ VM's at all times w/ excellent performance. A cheaper solution would of course be the Intel DC s3700 on a budget but it's hard to compare those two apples to apples honestly. This guy will come dual ported SAS for HA env's, lower latency, DRAM-like access/etc.
Shamelessly stolen off a description online :-D
The ZeusRAM™ is designed to merge DRAM performance reads and writes with flash backup persistence. It is an enterprise class, wear-resistant solid state drive (SSD) targeted for high write transaction oriented environments that require fast write-commit capabilities to enhance user-application throughput of NA and unified storage appliances. The drive is Plug-and-Paly (PnP) compatible; no additional device drivers are required to install the drive. The SSD is recognized by Pnp-compatible operating systems and PnP-aware BIOS.
Performance
The drive can operate at sustained read/write transfer rates of up to 500MB/s. The dirve is capable of performing 80,000 random read/write operations per second. the power dissipation is TBD% less than disk-based drives. The solid state design eliminates electromechanical noise and delay inherent in traditional magnetic rotating media.
Disk Capacity
The drive has an eight(8) gigabyte memory capacity. the high-IOPS, low-latency rate is achieved using an array of DDR3 SDRAM devices as the main processing and storage memory. The non-volatile backup memory is an array of Single-Level Cell (SLC) NAND EEPROM flash components
