SATA III vs SATA II

SATA III vs SATA II
If I bought an SSD running at max SATA III speeds, how would I get it to max that speed out? I mean I don't have USB 3.0, I don't have another SSD to transfer stuff. However, would having SATA II speeds affect random 4k read/writes? I'm thinking of getting a Patriot Torqx 2 (sata 2) 64gb for $80 bucks minus 20 in rebate for my laptop.

Well, the SSD will run as fast as it can given any workload.

"would having SATA II speeds affect random 4k read/writes?"
Nope, those don't go that fast yet.

A SATA II SSD won't be limited by the interface, a SSD will only have SATA III if it can take advantage of it.

Although that is true for SSDs, there are also many SATA III HDDs that can't even come close to approaching the SATA II cap, yet they'll sell that at a higher price because it has a SATA III connection. You have to be a bit wary on that front.

RE: SATA III vs SATA II
So basically as of now, SATA III's only benefit is a faster transfer speed? Read/write etc?

Yep, SATA II caps out at 3Gb/s while SATA III caps out at 6Gb/s. Most SSDs, at least the ones you would want to buy, are far surpassing SATA II speeds, and some are coming close to the SATA III ceiling.

RE: SATA III vs SATA II
Mind you, the SATA II maximum transfer rate is only limiting in the case of sequential transfers, that is transferring large files from one spot to another. When it comes to booting the OS, launching programs, games and the like, the drive is reading/writing a lot of small files, which isn't fast enough to be limited by the SATA II connection.

RE: SATA III vs SATA II
Still, you'll probably want to just go with a SATA III SSD, just make sure not get a SATA III HDD! haha

Nothing wrong with getting a SATA III hard drive, it's not like it will be any slower or faster than a SATA II hard drive.

RE: SATA III vs SATA II
Just a marketing scam though, well I guess if somehow the SATA III version is cheaper...
I need to get back in the swing of things, I've been dropping off recently, not following the latest news as closely, it hurts!

RE: SATA III vs SATA II
Okay so I see nothing wrong with buying a SATA II SSD since I won't have anything to transfer to the SSD anyway especially since its such a low GB sized drive
