What is the fastest ssd ever prodused? I dont want one but i would like to know how fast they can get. Mostly the read Gb/s specs if you would be so kind.

PCIe SSD's are the fastest. They are much quicker because PCIe has a higher bandwidth than SATA. There are some consumer products out there but most are aimed towards businesses and cost upwards of £25k. 3 GBps (read) / 2.5 GBps (write) e.g. on the HP iodrive2 Duo. The reason they get such high speeds is that they run SSD's in ultimately RAID 0 meaning they can write/read from both at the same time therefore increasing throughput.

The 840pro is also very fast. I'm not sure what's come out since then.

The problem is the 840pro and other speedy drives all top out at around 550MB read. This is about as fast as the SATA3 interface can handle. (Theoretical max of 600MB.) We need SATA4 if we want faster speeds, or PCIe based solutions.

Did you mean the fastest solid state drive ever or just consumer oriented solid state drives? There is a huge difference.

Among consumer oriented ssd's the fastest are the PCIe 2.0 x8 ssd's. Two examples would be the Mushkin Scorpion Deluxe PCIe 2.0 x8 ssd, and the OCZ RevoDrive 350. It is not unusual for them to reach sequential read and write speeds of 2GB/s (2,048 MB/s) or more. Random read and write speeds typically exceed 100,000 IOPS.

If you just meant standard SATA 3 6Gb/s solid state drives, then the Samsung 840 Pro and 840 EVO with the new "rapid mode" technology enabled are the fastest. I have an 840 EVO with rapid mode enabled in one of my personal pc's. I just ran the Samsung SSD Magician performance benchmarks. Here are the results:

Sequential Read: 1,190 MB/s
Sequential Write: 1,041 MB/s
Random Read: 101,229 IOPS
Random Write: 132,953 IOPS

The enterprise side of the market is a whole universe unto itself. There are different types, different configurations, and different arrays that can easily outperform consumer ssd's. The downside is the cost. You would have to win the lottery to be able to afford it.

Interesting Johnny. Magician kept saying there was an update but I don't tend to do that if all is well. I'll have to do that and take a look. I did a quick websearch to see how they cross the 600MB limit. The article I read said something about using system ram as a cache. I've got plenty of that, but I can that being a problem for anyone who has only 4GBs.
