Again, current high end SSD's are already saturating SATA III 6.0 Gb/s (sustained sequential). Enterprise SSD's already achieve higher than SATA3 speeds with SAS. While no hard drive can even saturate SATA2, SSD's are a different beast. I believe M.2/NGFF versions of the Samsung 840 PRO are getting over 1 GB/s sequential (>8 Gb/s) on laptops with PCIe M.2 ports.

Maybe you should look up the difference between a bit and a byte before making those statements.

Is there some site/benchmark/book that you can point me towards that you can validate this information and help me understand better as to why they get away with saying 6.0Gb/s when in actuality it is 600Mb/s?

Small letter "b" is usually used to denote a bit. Capital letter "B" is usually used to denote a byte. There are 8 bits in a byte. 600 Mb/s is not the same as 600 MB/s.

I'd point you to the official specifications but you have to pay for those.

Not true. I reckon even one of the high capacity Samsung 840 EVO with TLC NAND is already capable of saturating or even exceeding SATA 6.0Gb/s (particularly in TurboWrite mode). SATA III is a bottleneck for high performance consumer SSD's. That's the reason why there's a major push for PCI Express based standards. That said, the big jump is going from HDD to SSD (with near 0 access times and 10-100x random small block performance) so really, practically any SSD will be an upgrade.

your right on the Samsung 840 Pro, I researched a little more after reading your post and bought a intel ssd on sale for $169.99 for a 240GB.

yes they do, I said that in fact, but he's not paying $900 for a drive either. These drives do exit, but they are outside the scope of this project, and therefore don't matter. If 5 years we probably will see consumer drives that need sata 6. But not right now.

Last I checked, you can get 240-256GB models of the Plextor M5 Extreme, OCZ Vector, Samsung 840 Pro and SanDisk Extreme II for around $150-250 so nope, no need to spend $900. Those drives already saturate SATA III 6.0 Gb/s. SSD's have been hitting SATA III limits since last year (earlier if you consider SF-2200 with compressible data). If you don't understand why, I suggest you re-read some of my earlier posts particularly those pertaining to the difference between bits and Bytes.

Ah I see now, then you are most definitely correct, thanks for the info.
