SSD , optical drive questions

Howdy folks, i got a few questions before i finalize my order.

Why is it that SSD's inserted into the optical drive "place" cost around double the price of setting into the primary hard drive space? I would like to get a 128GB Crucial M4 Series SATA3 SSD + some Hard drive space for the usual junk.

Should i put the SSD as the hard drive and buy an eternal HD ? or can i by the SSD someplace else, and insert it myself when i receive the laptop? Does it have to do with the caddy case?

Cheers, thanks for your help.

 

Put the SSD in the HDD place and the HDD in the optical drive.

Optical drive bay is only SATA II so it maxes at 200 MBPS whereas the HDD bay is SATA III so it maxes at about 550 MBPS.

 

The caddy needed does have some to do with the price difference. But as Kevinmcg mentioned you dont want the SSD in there because of the SATA port speeds. Put SSD in Primary bay and HDD in ODD bay.

 

Max theoretical speeds for SATA II and SATA III are 300 Mbps and 600Mbps, respectively. Those are probably more realistic speeds in real world benchmarks (just clarifying for OPs understanding).

Just to second Kevinmcg and Hutsady, go with the HDD in the optical drive bay. It's better as far as performance goes (and makes more sense) to put the performance-driven SSD in the SATA III slot, and leave the slower drive to the slower interface if it's only being used for storage.

 

thanks for the replies!

 

And of course you can buy aftermarket if you don't like that prices

 

Not to be nitpicky but I think the numbers above are slightly off
SATA II max 3Gb/s = 3000Mb/s = 375MB/s
SATA III max 6Gb/s = 6000Mb/s = 750MB/s
Correct me if I'm wrong
As Prostar mentioned you wont saturate SATA III speeds yet but you can II with current SSD's

 

Representatives, Let the BATTLE begin!

I also noticed that, xotic, but after arguing with myself I decided that prostar is correct. Some people say that theoretical max of SATA II is 375... and due to 2 correction bits of 10 we get 375 - 20% = 300Mb/sec which they call practical max speed.

On the other hand some other people say that we can't call 375 as theoretical because even in theory we can't disable those 2 bits correction and therefore those speed is fully impossible... Even in theory. So They call 300MB/sec as theoretical max while practical max depends on SSD manufacturer and I saw 280 MB/sec plus smth on either Vertex 2 or 3 connected to SATA II. And most likely Vertex 2 because I oftenly heard rumors that native SATA II works better on their interface than downclocked SATA 3 versions.

Welcome.

 

SATA II max is around 270-275MB/sec depending on the controller, this is what you will actually see from any drive.

High end SATA III SSDs currently saturate in read speeds the SATA III bus.

 

Thats what i was leaving out of my numbers.

 

I also think it's noteworthy that James and I stated the theoretical speeds as "Mb/s" and not "MB/s".

We sound like such nerds right now. Now let's talk about who was the better Captain of the Enterprise!

 

LOL you found 1 wrong out of 3 written Now I have paranoia that someone is watching each of my posts

 

i'm also interested in a SSD shortly but have a DVD drive. where would i move my primary hard drive?

 

depends on whats more important to you (and would thus make more sense inside ur laptop): the optical drive or a second hard drive? (assuming that ure gonna install the ssd as ur primary drive once u get it, would be the only alternative that makes sense, naturally)
either way, ud get an external case for one and install the other

This is why the mSATA drive is nice and it's just a shame it's wired as SATA II rather than III, but with UEFI booting I doubt you will see much of a difference.
