Yes, 50K read 40K write 4KB random IOPS. I've seen these numbers elsewhere also.
Here's a page with a bit more info on these drives, and other SSDs from foremay:

I'm not surprised you can't find them in e-tail, as they are enterprise drives.

BTW, OCZ has released Z-drive R2 now, and it's bootable
http://www.ocztechnology.com/product...press-ssd.html
512GB with 1,3GB/s read, 550MB/s write.
1-2TB with 1,4GB/s read, 950MB/s write.
4KB random IOPS is listed as 29.000 read and 7.200 write in the product sheet PDF.
The editor at storagesearch.com comments:
R/W IOPS are 29,000 and 7,200 respectively - an order of magnitude slower than the fastest PCIe SSDs today - but nevertheless useful for many applications - unlike the original Z-Drive (March 2009) which so slow that it couldn't be regarded as a serious contender.
If i remember correctly, this is based on an LSI 92xx-8i. I am not sure wich SSD controllers are used in the RAID array, or the stripe size. Cache is listed as 512MB, but if that's the RAID controller cache, or the sum of SSD caches i don't know either.
