SATA II vs III
- Thread starter vitalym
- Start date
For a HDD there is virtually no difference at all. For an SSD there isn't also, except a minor capped performance for Micron 6Gbps controller like in Crucial C300; but even that one doesn't go higher than 335MB/s or so - and only for reads.
6Gbps SATA does mean lower propagation delay (average time to send a command or I/O request data) - an effect which causes higher IOps in some cases on the 6Gbps interface even though the total throughput for that test never exceeded the bandwidth of 3Gbps interface (300MB/s).
So the bottom line is: no, SATA3 HDDs are good marketing, and i highly recommend you connect them to your chipset (SATA2) controller instead because it's usually better quality than third party chips; like the Micron 6Gbps SATA controller. Especially when using RAID the 6Gbps Micron controller is slower than the 3Gbps Intel chipset controller. Funny indeed! ;-)

From all the benchmarks I've seen, forum posts I've read, etc.:
SATA II is fine for HDD's. From what I understand, they'll never even hit the limits of SATA II anyway. With SSD's, that's where SATA III could make a difference, and in some cases a fairly big difference.

Any suggestions on a SSD drive?

Waste of your money with the next generation of SSDs around the corner, IMO. If you want an SSD now the Intel X25-V 40GB or similar cheap SSDs wouldn't be a bad buy tho. Especially for read heavy / write light environments.
Oh word, I didn't know...I'm in no hurry.
I'll look myself, but if anyone has any good links about the new SSDs, I'll appreciate it if you can link it.
Not much info is available, but Intel and IMFT (Micron-Intel joint venture) will be releasing new generation SSDs with 25nm NAND. Some info about the new Postville 25nm refresh has popped up:

Basically, it will be the next generation of SSDs. currently we have the second generation of TRIM-capable multi-channel NAND controllers. The third generation likely brings massively higher write speeds and much better storage capacity per dollar. In particular, the new 40GB SSD that will be introduced January/February will add great value to fast but small SSDs.
