Resolution for Seagate Momentus XT ST95005620AS 500GB with SD26

Don't know what ya talking about

I've been running the seagate hybrid harddrive in my MacBook Pro for about a month now and it came preloaded with SD26 I have not had a problem and I'm on this machine everyday The only other thing I've done is upgrade the ram to 8 gig however this should not affect the harddrives performance in any direct way
All I can think of is that these harddrives are NOT being installed properly

I think there fantastic

I'm running SD25 and having the same excellent experience as well Pete. Have bought 4 of them all up and had nothing but great performance.
 
I think you all need to do more research

OK dsio
I'm glad to see that I'm not the only one more than satisfied with the seagate hybrid drive. I believe we all should be. For those of you that can't be bothered or don't bother reading howto's On apples us site there is a step by step manual as to how to change your harddrive all you have to do is look for it and read it.
Never presume you know everything as every company does things different .
Also seagate has a howto on harddrive swapping though I would recommend the one one from apple
All the best to all of you who upgrade there harddrive no matter with which one

where to find hard drive howto

http://manuals.info.apple.com/en_US/MBPRO_13inch_Mid2009_Hard_Drive_DIY.pdf

Although it say's mid2009 I found that it can also refer to early 2011 MBP's
It's all pretty much the same inside

Hope this help's some of you's

Also one thing I've noted since putting the XT in is that battery duration has diminished
The exact amount of time is unknown as I haven't bothered timing it
It's not important to me

To dsio
You say you have four XT's for your MBP the question is : What sort of array are you using to have them all going at the same time or are you using them individually ???

Thanks dsio

I was interested to know how to build something like a raid array I'm quite sure it can be done but was trying the easy way rather than doing the research myself

I briefly tried RAID0 on MXTs under Fedora Linux, the performance was as you would expect, very snappy, and the cache still functions correctly as its filesystem unaware. For my laptop I'm probably going to go 1x 240G Vertex 3 + 1x 750GB scorpio black just for the extra capacity (the scorpio because in normal usage its faster than the MXT and as a storage disk the MXT's 4GB SSD cache is irrelevant.
 
Sorry, coming in a little late to this thread. I do have to admit I am a little confused, I've bought and used two of the Seagate Momentus XT and haven't seen any of the issue described. Infact my 2008 Macbook Pro I am using to comment to this thread has one with the SD25 flash, which I've update during the last 12 months with each release.

I've also found the SD25 flash fixes the spin down issues and I am noticing I'm getting a little more battery life compared to SD23...

I'm making an educated guess here but I think the issue the OP has had nothing to do with the drive but how you've installed it rather you're using faulty media or just doing a straight copy of media.... (I do apologise if this has been mentioned).
 
I've been running OS X 10.6.8 on my Momemtus XT SD26 firmware. I have no problems at all and it is very fast.

It's normal first time you cannot see the HDD during the OS X installation. You need to click the Utility on top of the menu in the OS X setup. Select Disk Utility and format it to Journal+. Then you can see the HDD on the list which it will be available to install OS X on it.

Nothing is magical. Most users panic when the OS X setup isn't listing anything to install onto.
 
Just to add another experience of this drive. I installed one two days ago into my 2010 15" macbook pro i5. Followed the installation instructions in the mac manual, booted from the mac install disk, formatted the drive, restored osx from my time machine drive (took 3-4 hours) and it's working brilliant.

I've noticed a big improvement in speed over the original hitachi 5400rpm drive. Programs open almost instantly, where as itunes might have taken 5-10 seconds before. It's going to be great for serious music work in Logic.

The drive came with firmware SD26.

The only issue I have is that Smart Drive (SMART monitoring software) keeps telling me that the drive is on the verge of failing, as the Seek Error Rate is up to 100,000. Apparently this is normal in Seagate drives though, so my solution is to uninstall Smart Drive!

I honestly think that in terms of performance and storage per dollar for real world use, the Momentus XT is by far top of the heap right now. For your every day use, OSX, iTunes, Chrome/Safari, Adium, all of that fits neatly into its 4GB flash cache.

Totally agreed. Am very happy with mine. I had a SSD before but I found the value for money too low compared to the XT.

Yep, just testing out the speed, from pressing the power button osx now boots into a usable google chrome window in 1 minute flat, including typing a login password. My android phone takes that long! Never timed it on the old hard drive, but I'm sure it took twice that time at least.
 
I installed my drive on Lion launch day and put a fresh copy on. I haven't noticed any drastic improvements in speed and it still takes around 30 seconds to boot to the login screen. What gives.

Reboot the machine 5 times in a row, then time it on the 6th. If it hasn't decreased dramatically, you've got a dud.

If its a Santa Rosa chipset with an ICH8 southbridge, you're on SATA 1 with about 130-135MB/s peak, and the Momentus XT will saturate that easily on boot when its reading off the SLC flash. SATAII is needed to take full advantage of the XT.

Early 2008 MacBook Pro. 2.5GHz Core 2 Duo with 4GB of RAM. Positive it's the XT with the 4GB of SSD.
Click to expand...

If you're an early 2008, that means you've got a Penryn chip in a Santa Rosa board, and your southbridge is still limited to SATA 1 speed ~130MB/s, so the acceleration from the Momentus XT running off the SSD cache is being limited severely as all it does is saturate the SATA bus. If you had the late 2008 Macbook Pro, the MXT would perform nearly twice as fast running off flash. You'll still get some benefit, just nowhere near as much as you could.

I noticed I have SD23...:eek:
Everything works well but if I can get a nice speed bump by upgrading to SD25, I'd like to do it..How do I upgrade? :confused:

Shouldn't see a speed bump, just stability changes making the drive moe stable and possibly extending battery life as it will efficiently sleep and wake.
