Since my Macbook Pro is capable of Sata III, and my current Vertex2 SSD is only Sata II, I am just operating a Sata II speeds. My current Vertex2 SSD does boot up in @ 18-19 secs from power button to useable desktop (auto login)
I wonder what "everyday performance gains" I would see by installing a 256gig Samsung 830 SSD (Sata III capable)?
HAs anyone here upgraded from a Sata II SSD to a Sata III SSD, and what did you notice speed/perfomance wise... EX: boot up time, snappiness, etc....?
Hi Ian,
Funnily enough, I am in the process of selling my mid-2009 Macbook Pro, into which I had installed an OCZ Vertex 2 240Gb SSD. Rather than migrate all my content onto a spare drive and wipe, I decided I would sell the MBP with a brand new disk, charged at cost to the new owner. Originally I was budgeting fifty quid for a 500Gb HDD, but I suggested that the imminent new owner might consider one of the newer generation SSDs which have plummeted in price. He decided on the Crucial M4 256Gb SSD, which was duly ordered and installed.
The Vertex 2 is a SATAII and my MBP is only SATAII (I think) and I was very happy with the performance; quite a bit faster than a regular or hybrid HDD and with adequate capacity. I wasn't really expecting much of an improvement from the M4.
However, after installing 10.6 onto the MBP (from original discs) and doing some updates to latest versions of various things, I was only too aware how fast the MBP suddenly felt. For instance, with the Vertex, 10.7.4 would take around 20-22 seconds from off to login screen. With the M4, it is 6 seconds (albeit to a fresh install of 10.6.8 so that may have something to do with it).
The disk speed tool I have suggests that the Vertex 2 averages around 80MB/s write and 130MB/s read, and that's on a year-old SSD with around 1/3 free space. Not great figures, and lower than I expected, but then this could be due to fragmentation*.
I haven't tested the M4 but I would be surprised if it weren't at least double or even triple those figures.
The point of this rambling post is to let you know that provided the Samsung 830 is a current generation SSD (which I believe it is), then you might actually experience a quite profound speed bump by upgrading, even if (on paper) the difference should be quite subtle. My experiences run contrary to what many have written, and it could be due to the fact that it's a fresh Snow Leopard install on a 90%+ empty drive, as opposed to a year-old-and-migrated-to-Lion working install, or it might be due to improvements in drive tech. I can't really say.
Hope this helps. If the new MBPs come with a cheap HDD option (as opposed to all-SSD) I may splurge for an M4 for the new MBP rather than press my Vertex 2 into use; the Vertex would make a fine, very fast additional drive for media and in a USB3 caddy could be a really fast drive indeed.

* has anyone used iDefrag on an SSD in Lion? Safe? Recommended?
