question about ssd harddrives 3 gb vs 6gb/s

[Newbox]

Hi all.

I upgraded my pc a lot and all stats basically got full score on windows index, except my harddrives. It shows as 3 gb/s (got a 68 score)


My harddrives, which was installed back when i had a older system, was formatted with IDE. I did the "achi" quickfix in the registry, rebooted and interupted the startup, went to setup, changed the harddrives to use achi, and after windows booted up fully it "automatically installed the drives to support it".

Hm, ive tried to find stuff on this but...are there ssd¨s that operate on 6 gb/s?


Im considering if i should reformat the ssd¨s i got, choose achi, then do a fresh win 7 ultimate install, or not.

If it will mean a faster harddrive, sure

Ty again for any insight..

(sidenote: my motherboard, the asus rampage extreme 3, got two sata 6gb ports. I currently have two ssd¨s connected to those ports..doubt it makes any difference but ohwell).

There are SSDs hitting 4.8gb/s. Remember 1 byte = 8 bits.

not sure if current SSD's even saturate a 3G/B unless in a raid. But the upcoming SSD's this year should be some amazing stuff. Even the low consumer SSD's should be a significant upgrade to current SSD's.

But the question is yes, there are SSD's that use 6G/B. I only know of the SSD's by crucial that support 6G/b. I would not put too much stock in the windows index stuff, my new graphics card (6950) scores a 5.9 in 3D =/

You're doing the math wrong

1 byte = 8 bits

SSDs easily range from 350-450MB/sec

2800 - 3600 Mbit/sec

2.8 - 3.6 GBit/sec

Sata2 is only 3Gbit/sec. Not 3Gbyte, but 3Gbit. Also, the transfer rate for SATA2 3G is actually closer to 300MByte/sec max.

So yea, SSDs will saturate 3G/s pretty easy. In fact, SATA2 is more than likely slowing down SSDs, even some of the cheap ones at that.

Also, very basic RAIDs will exceed SATA2. For example, I benched a 4x2TB Raid stripe, where the hard drives only cost $89, constantly hit the SATA2 cap, and could easily gain 50% extra performance should it be SATA 6Gb. This is 8TB for under $400.
