Anyone with an MXT 750 GB out there ? Would like to hear some input, in comparison to the previous MXT 500 GB drive.

I'll be grabbing 2 once they are out in the UK.
Anyone got any info on which MBP's they work with - same as v1? (both our MBP's have them in, and they have worked _flawlessly_ - mid-2010 15" and a late 2009 13")

Yup, seem like it got 8gb slc + 2 375gb platter,
Here is a review :

Judging by the fact that most users only use a tiny portion of their drive space actively (that is, lots of frequent reads and writes)...
The 8gb SLC flash should be quite an improvement even before the "partition" off of the section for the OS.
Given the way I use the drive, I would have preferred 16gb... and paid the premium for it.
But then, I would also have paid for a bigger DRAM write cache.
I wish Seagate would put out some tools to let us play around with the way the cache works --- and do things like clearing it.
My drives are arriving shortly --- so lets see what real world testing brings.

A typical review with benchmarks that measure things that have a tangential relationship to real world performance.
But then, it is nice to see how a few of the reviewed drives got such good scores, which was achieved by tweaking the firmware to post good results --- knowing exactly what the measuring yardstick is throwing at them.
Significantly, some of the best designed SSDs out there --- the Intels --- do not necessarily get the best scores, but tend to be far more reliable (yes I know of their crashes, including the most recent doozie too).
The only problem is in the real world, those measured "high" speeds may come at the expense of many other things that matter, like real world speed in actual applications, and particularly, in reliability, stability, and.... actual speed with real life applications and real users.
It does look to me that someone from the "pure" SSD crowd that have a horse (or a stable of horses) in the race don't want the world to know how unreliable many of the SSDs that are sold really are, and how they are playing games to get high benchmark scores --- and what tradeoffs are being made, especially in things like testing and validation.
Is that the reason that certain interested parties seem to be so interested in the Momentus XT line?
One can't but notice certain persons taking so much time to comment on many threads and complain about "defects" even as they say they got better price performance elsewhere (and should never buy another XT again)?
Maybe it is their intention to raise enough smoke to distract attention from a competing product that is delivering about 80% of the benefits of a "pure" SSD for the typical consumer user at a fraction of the cost.
The Momentus XT is probably the biggest threat to the low end and consumer grade SSD market out there.
Maybe I am the one in a million that is lucky to have the one good one Seagate put out (that worked well with factory firmware and every upgrade since).
Or is it because I know too much about SSDs?
I am expecting that in the next 6 months, many other vendors will rush into the Hybrid SSD space now that the path is proven by Seagate --- and consumer acceptance of the product is proven.
A few more things need to happen --- like tighter integration of Hybrid drives into the OS and equivalent of the "trim" command for SSDs for Windows 7's successor but for Hybrids.
For the curious... Google "Windows 7 Enhancement for SSDs Powerpoint"
That should happen by the next version of Windows --- assuming that Seagate and other Hybrid drive vendors are doing their job lobbying Microsoft.
Expect to see hybrid drives in mid-market / low-high end gaming machines.... like mine in a year.

Guys, look at WiseFool, sorry, WiseDrive ! Here we have a TOTAL Seagate fan. Let's hear some applauses for this troll ! Moderator, you will probably delete this post, aren't you ?
He has no idea how much faster a real SSD really is than these hybrid drives. The reviews checked the drives (yes, even SSDs) from every possible angle, nobody is hiding anything. Maybe there is only a little bit of paranoia in some people's heads.

Hey,
Sorry WiseDrive, I'm not sure I fully understand what you are trying to say. Yes synthetic benchmark might not reflect real usage. Yes SSD have stability issue(noting this a personal experience from someone on the internet). But then again some users do have stability issue with MXT and no you're probably not the only one for which the drive work. It's not all black and all white for both side. The review I've link do recommend the drive(in some charts, MXT does beat some SSD) and do mention that, at the current price of rotating hard drive(due to the flood..), SSD are an attractive solution.
Regarding the future, I'd rather wait for it to happen as it took a lot of time to develop the new MXT...
Here is an other review for more information(which also recommend the drive). This one mention a possibility of write caching in the future.

PS. I'm eager to see what you have to say after trying the new MXT

Have a look at the single chart that most closely approximates a real world experience.
A difference of 30 seconds over a base of 147 seconds for the fastest SSD in the sample.
That is about 20%.
Achieved with 8 runs to condition the Hybrid drive --- with more improvements possible and probable.
Except that the Seagate Hybrid is not selling for anywhere near the price of the low end SSD.
The present flood induced price spike is an anomaly --- and not reflect the true cost / likely market price of the drives once the situation is resolved.
Improvements to the alogrithium is also possible -- and probable over the life of the drive (5 years).
Now tell me which consumer grade SSD have a 5 year warranty.
Typical consumer grade SSD warranties: 3 years, 2 years for one major brand.
Oh... then there is failure modes.
When an SSD fails, it dies.
When a Hybrid's flash cache fails.. it defaults to a regular cacheless conventional HD.

How do you know this ? It was specified (I believe) only for the 750 GB MXT drive.
The first-gen 500 GB MXT people are talking about is different.
How can the firmware realise that the SSD is (partially) damaged ? I'd really like to know....
