I have a 256GB SSD in my desktop computer, so I'm writing this review as someone who is accustomed to that kind of performance.

The 750GB version of this drive is awesome. (I've used the previous model, the 500GB Momentus XT, and it was "pretty good." There's more than just a capacity upgrade to this new version.) I installed the 750GB Momentus XT into my new HP Envy 15, and I have to admit that it's the perfect compromise drive. The Envy has only a single drive bay and the optical isn't removable, so an SSD / HDD combo (one for the OS and one for storage) isn't an option. I'm a wedding photographer who needs to get work done on the road, and I regularly need to carry 400+ GB of data around, so a pure SSD solution (at least for a reasonable price) also isn't an option.

The drive learns quickly to cache the most used data, and it really accelerates anything you use frequently. My laptop boots very fast. Almost as fast as my desktop. Same for Chrome, Adobe LightRoom, and all the other apps I use on a daily basis.

If you're looking for an affordable solution that hits the sweet spot between SSDs and HDDs in performance and capacity, this is it.

Note to Seagate: Make a 2+TB desktop version of this drive with 32GB of NAND, and I'd be all over it!

The original review is below. The negative initial warranty experience was also shared by others as reported in comments. But, the important parts to read are the updates at the end which explain the current 5 star rating. My eventual outcome was positive.

I hope the review with updates are helpful to potential seagate purchasers.

************** original review ***************

The seagate momentus XT 750 does a really nice job of providing SSD drive like performance and ample space for data for a fraction of the cost of a pure SSD. Caching when well used can get a large percentage of the perceived speed advantage of the much faster overall drive by saving the most frequently used data in high speed storage. It workd really well in most applications and this is something my clients have seen such as when they reboot their windows PC's.

When data is not in the cache it's pretty much just a 7200RPM laptop drive. Pretty quick, but not like a SSD. The 750GB has twice the flash cache of the smaller versions and appears to me to have better caching firmware. The firmware detects what's read frequently and tends to keep those parts of the hard drive data in the fast flash memory. The result is apparent after a few restarts and hours of use. Frequent tasks or programs - rebooting, word, outlook, etc. tend to start more quickly. If usage patterns change the drive cache catches up.

Because of it's innovative caching design this drive provides an excellent price-performance value point. Especially with large amounts of data. If you only need a small (128GB) hard drive, spring a little more for a pure SSD. If you want to have a lot of space, this is the drive.

Update: February 2013 the particular drive I reviewed here just died.

This is noticeably faster than the 500GB version. I really wanted 1TB, but 750GB will do for now. I have it in a MBP 15" with a second 1TB hard drive in my optical bay.

Seagate had some problems with their 500GB hybrids, but seemed to get the issues worked out with new firmware (I never had a problem with mine). I haven't experienced any issues with the new 750GB either, but it will take time before I can comment on the reliability long term. I check my drives weekly for data corruption, and so far have found none, nor has there been stalling or other issues.

Did I mention this drive was fast?

Purchased this recently for a early 2011 MBP 17"-2.2GHZ 16 GB ram, Lion & Snow Leopard & data partitions (3 in all-in same order of creation) The drive replaces a Samsung 1TB 5400rpm drive- which had replaced the stock Toshiba/Apple 750 GB 5400 rpm drive. Formatting & copying the previous partitions on the Samsung to the new Seagate was done via SeriTek 6G expresscard while Seagate was still external. Installed after copying w/o event, booted fine. Apple system profiler show the Seagate drive connecting at the 6G speed- no issue's, not like the well reported 6G SSD connection trouble with early 2011 17" & some 15" MacBook Pro's. My 17" BTW was built in April 2011 & reports 6G in HD bay as well as in optical bay.

The new Seagate is very quiet while copying outside the MBP. Not much info on outside of its case other than Seagate name/size of drive, manufacture date-11/2011, part/model/serial numbers, firmware-SM12 and rated @5V .70 amps. And made in CHINA (Amperage draw is lower than the Samsung 1 TB which is .85 amps & Toshiba/Apple 750 GB rated at 1.0 Amps. both of which are only 5400 rpm drives)Does not state speed, flash memory, or cache size, or SATA interface speed- which are 7200rpm, 8GB flash memory, 32MB cache & SATA III or otherwise known as 6G. Seagate did a pretty good job with current draw on drive compared to other laptop drives- inc. Samsung & Toshiba/Apple stock drive.

I don't know how they are cramming all this stuff into a 2.5" form factor- but the Seagate weighs more than any of the 2.5" drives that I have here. The Seagate comes in at 3 7/8 oz.- somewhat heavier than the other 2.5" drives(I have).
