My Experience: Hybrid SSD/HDD Harddrive (Momentus XT)
Hi folks! I recently "took the plunge" and installed a Momentus XT Hybrid Solid State Hard Drive today and I thought I would share my experience. It took a lot of soul searching and research. It turns out I made the right call :-)
I have a 17 Inch MacBook Pro (Early 2009). I recently upgraded my ram to 8GB (the max). The stock hard disk was a 5400 RPM 320 Gig Drive. I was afraid it was going to die on me in the future. I also wanted to have some more storage space. As tempting as the Retina MacBook Pros are..I decided I want to get at least one more year out of this computer. So I upped the ram and now the hard drive.
I did a ton of research and found nice things said about the Seagate Momentus XT ST750LX003. It is a 750GB 7200 RPM 32MB Cache 2.5" SATA 6.0Gb/s Solid State Hybrid Drive. That means that aside from the 750GB of regular 7200 RPM storage...the drive also has 8GB of NAND Flash memory on board. The drive uses algorithms built in the firmware to figure out which sectors to store in flash...and which to save on the HDD. Generally your OS and files you access the most are stored in flash. This is the 3rd generation of Seagate Solid State drive. The previous generations had 4Gb of NAND. This puppy has 8!
Now I want to preface something...my generation of MacBook Pro is only capable of SATA 3.0Gb/s transfer. The drive is backwards compatible. So those of you with a newer machine may notice even more improvements!
When I installed Mountain Lion on the stock 5400 RPM drive (with 4Gb of Ram at the time) It took me about 76 minutes. With the new drive (and now 8Gb of Ram) it took me 32 minutes. I was shocked.
My boot time with the old hard drive (and the 8Gb of ram) was about 1:11 (I measure from chime to "ready to go" with Auto-login turned on). With the new drive the same task takes 31 seconds.
I am in shock at the speed gains. Everything goes quicker. I am so thrilled.
Thus far the only drawback...the new drive runs warmer than the stock drive. Not a huge inconvenience...but I do notice my left hand getting a little more toasty than before.
Has anyone else used this drive in their MacBook pro? I would love some more Feedback.
I would recomend this to anyone who wants to expand their unit and gain some extra speed. Google around and you will see a lot of very convincing speed tests.
