Jun 23, 2009 12:37 AMby ldoogy,CTB: I guess the real question is about the drives themselves. I trust them that the system now supports SATA II, but I'm not sure I believe that their SSD drives are SATA I. A quick look at NewEgg.com (who carry many SSD drives) shows that 89 of their drives are SATA II while just 7 are SATA I, and those are all old drives with smaller capacities.
I wonder which drive manufacturer would make a 256GB SSD (which is obviously a fairly recent product based on its capacity) but would only use a SATA I interface. Seems unlikely no?
Very curious to hear what you see in your systems. I'm particularly interested in the exact model of the SSD drives you find in your systems and in benchmarks. If you have the time, it'd be great if you benchmarked your 15" MBP BEFORE applying the firmware update and AFTER... That would really be insightful. -
Jun 23, 2009 4:40 AMby AlecGold,Well, I installed the 1.7 Efi, but the system hung after booting.
so after about an hour (well, close to 55 minutes) I gave a reset.
Nothing
reset and pram reset
and it booted again as it should do.
But now my uMBP 13" freezes for 30s to 45s when it gets a high CPU load.
Any ideas? -
Jun 23, 2009 6:41 AMby AlecGold,well, it got even worse, I noticed the temperature getting high and then I found out the fan was blowing 2001 rpm with a temp of 89C/around 190F
That is no good.
But that would make sense that under high cpu loads it freezes until it cools down, gets hot, freezes... etc
Tomorrowmorning it goes back to the store it came from.

Jun 23, 2009 10:41 AMby Haricot,I have a week old CTO 13 inch pro (with SSD HD) that works fine. I have no attention to apply the firmware and wish the software update wouldn't pop up automatically. Sure I ignored it but how many people know what it really is and will install it and potentially have something go wrong when they didn't even need it to start with? .... -
Jun 26, 2009 7:46 AMby Haricot,OOps I meant "intention"
And no, the MBP came with a 1.5 gig interface even with the Apple SSD installed. Until I know the reason why Apple decided to downgrade it to 1.5 gig I'm not installing any firmware upgrade. With Apple there's often a good reason for their original decision to start with. Not sure why they decided to make the firmware update pop up instead of having it downloaded separately for those having a need for it... -
Jun 26, 2009 8:32 AMby ldoogy,Thanks Haricot! That's actually completely useless because your drive is actually branded internally as an Apple SSD drive! This is rather unusual -- almost all pre-installed SSDs (from Lenovo, etc.) are always simply third party drives that would report their original manufacturer.
Could Apple actually be purchasing MLC chips and SSD controllers and manufacturing their own SSD drives? It seems unlikely.
Still, we are in the dark regarding the actual interface employed by these drives. I'd bet they are SATA II but that contradicts their statement from the firmware upgrade... -
Jun 26, 2009 9:05 AMby Haricot,Yeah, I wondered about that. Well the only way to be sure of the vendor would be to open up the case and have a pick... I'll pass. At least for now
PS according to post #5 of this thread http://forums.macrumors.com/showthread.php?t=588540 it is a Samsung

Jun 26, 2009 9:07 AMby ldoogy,That's perfectly understandable Haricot... Please let us know if/when you change your mind...
One thing I'd love to see is a benchmark of this drive, preferably before and after the firmware upgrade, but I'll settle for a "before" if you don't plan on installing the update. By the way, I must say I am confident the update is very low-risk considering the earlier MacBooks/MBPs (late 2008 unibody) were based on the exact same chipset and ran at SATA II.
Anyway, any kind of benchmark numbers would be great!
