Most Expensive SSD

Z-Drive R4 from OCZ is a blazing fast SSD that fits on a standard PCI-express slot on the motherboard. The drive has a capacity of 1.6TB on a full height PCIe card. The Z-Drive R4 looks like any other PCIe card with no cover/shroud on it. It has two PCBs on top of each other to accommodate the controllers and you’ll see a black heatsink to the extreme left of the drive which cools a Marvell SAS controller. The back of the Z-Drive R4 is laden with 32 Intel MLC NAND chips. OCZ Z-Drive R4 runs on eight SandForce SF-2282 controllers. There are four controllers on each PCB. OCZ has packed an insane number of MLC NAND chips on the Z-Drive R4 and the drive has a total of 128 Intel 25nm MLC NAND chips i.e., 64 chips on both the PCBs. This can be easily understandable considering the drive can be bought for  a whopping Rs.1000000 lakh [aprox.]
