My computer takes too long to boot up. Around a minute and 18 seconds, to be precise(r). Which is why I want a solid state drive. But I don't want to pay £400 for 256 gigs of storage. Enter Seagate's Momentus X Hybrid drives, which promise near-SSD speeds, but with giant HDD storage—and not-so-giant prices.
The second generation of Seagate's Momentus XT solid state hybrid drives, which combine a good-sized chunk of flash storage (4GB in the 500GB model; 8GB in the 750GB model) with a traditional 7200RPM spinny hard drive. The idea is that Momentus learns your most used applications and basically runs them off the flash storage, so you get SSD-like performance and boot times.
People who want SSD speeds, but HDD prices and storage.
It's a hard drive. You'll never see it.
Installation is either easy, if you've got the right machine, or it isn't. And then it's just like a hard drive.
It works. My five-month-old, Core i7 MacBook Pro's boot times went from an average 45 second boot time with the original 500GB 5400rpm Hitachi hard drive to 29.8 seconds. Brian Barrett's 2009 MacBook Pro's boot times plummeted from 1:34 to 30 seconds. Start times for database-driven apps were cut in half, or better, like Aperture (12.3 to 5.8 seconds), iPhoto (14.6 to 5.2 seconds), iTunes (9.2 seconds to 1.9 seconds). Even Photoshop start times dropped, from 21.2 seconds to just 3.8 seconds.
It's extra performance you can definitely feel day-to-day, if only slightly.
Still fragile like a hard drive. Also, it has to learn which programs you use the most before you see the most benefit. (So it doesn't exactly kill benchmarks, with 81MB/s write speeds with 100MB/s read speeds.) And obviously it doesn't boost everything to SSD speeds.
Shutdown times tripled, from 5 seconds to roughly 15.
Yes. If you want a taste of SSD speeds but can't afford one, or simply need more storage and don't feel like Frankenstein-ing your rig with a combo SSD/HDD setup. It's not a bad deal at all, with prices starting from £80, when an SSD with a third of the storage costs twice as much. But definitely get the 750GB model—not only do you get more storage, you get double the flash cache and interface speed.
