SSDs at 300mbps?

TheMorningStar · 24 Jun 2009 at 23:51

I believe that the maximum bandwith of sata2 is 300MBps (is that actual or thoretical?) looking at the SSDs around they seem to be maxing out at about the 250MBps range. When will we be seeing 300MBps drives do you think? and would raiding 2 of these drives actually give me around 600MBps do you recon?

not planning to get these untill next year given the premium of the drives at the moment, infact not untill 128gb drives are around £100 and hopefully 300MBps

but just wondering where they are at at the moment.

265 mbps and I reackon that is limited by the jmicron controller

sata 3

My G.Skill falcon can read at just over 260mb/s.

If you want more Sata 3 will be available by the end of the year or early 2010.

I'm not certain but I think SAS controllers can work with SATA drives also, and some SAS controllers are now available in SAS 6Gb/s speed...

Edit: Like this one for example: http://www.attotech.com/ExpressSASh608.html

Technical Highlights
ExpressSAS H608

■x8 PCIe 2.0 host interface
■8 internal ports in a low-profile form factor
■Outstanding performance with up to 6-Gb/sec per port
■SAS,SATA,SATA II connectivity

I wont be going for sata 3 for quite some time as I plan to have my current base system for the next 3 years or more with only gfx and posibly cpu upgrades in that time. Oh and storage drives.

It's quite sad I actually have the evolution of my pc planned out into next year haha! No space for a sata 3 card I don't think :s

Next few months another 1tb western digital green
End of the year masive GFX and PSU upgrades
Next summer SSDs and prolli another 1tb drive

Oh and thinking about it, it's actually 375MBps on a sataII drives theoretical bandwith, prolli slightly less with overhead n shiz.

3000Mbps / 8 = 375MBps (thats right isnt it?)

sata 2 with overheads is norm around 250-260MB/s (the spec is 300MB/s but with overheads can be an little lower)

but do not concern your self to much with SSD and data rate, its the access times that makes SSDs respond so fast not the data rate that a lot get to interested in (same goes for RAID for SSD for the most part Pointless you not notice the speed improvement apart from benchmarks that only state SEQ speeds any way not random access)

spec is 3Gbits/second (375Mbits/sec)
not sure about overheads but 300Mbytes/sec is the quoted max speed
