OCZ Z-Drive R2 E88 $9,000 29,000 IOPS (4KB 32QD)

[F@32]

Does it seem a bit weak (http://www.newegg.com/Product/Product.aspx?Item=N82E16820227581) for $9,000+ PCIe 8x SLC?

Note, I'm not knocking it down for 9K, since I do realize 512Gb of SLC NAND cost a fortune.

these are terrible. by comparison an array of SSD withe the right controller can top out at around 160,000 Random Read IOPS, and with only four good drives and a controller. under 2 grand.

9260 w. fastpath roughly 750

so you get a phenomenally better solution, which can also be expanded and upgraded in the future, for about 1800 bucks. this device is horrible compared to the other alternatives. MLC v SLC is just a big non-issue now, anyway. its all MLC now.

First I thought may be there was a typo in the price by a zero. Then I wondered if there was a typo in the IOPS by a zero... :confused:
I'm getting 51K @ QD16 (http://i15.photobucket.com/albums/a397/reieev/AMD%20SB850/742010/IOM4krandomreadRAID-0SB850QD167-4-2.png) just with the pair of lowly x-18M G1 on SB850 lol.

That thing must have the wiring by Monster cable and gold plated PCI-e connector...

ROFL big plus 1!

Figured bumping an old thread was better than making a new one.

It looks like this version of the Z-drive uses mini-DIMMs. Any idea if you could just simply plop in some RAM instead of the flash modules? Or would everything be completely off like voltage, memory addressing, etc?

Anyone?
