Excellent SSD for older Macbook Pro
on January 15, 2013
I purchased this drive in December 2012 to replace the old Western Digital 5400rpm drive in my 15" Macbook Pro (10,3 from mid 2007). This older Macbook has an SATA-1 bus in it, so I wasn't expecting a huge speed increase. However, I have been pleasantly surprised. The new drive has significantly sped up my system. On speed tests, I get a throughput of about 4 times what my old platter-based drive could give me, both on larger reads/writes as well as random reads/writes of tiny chunks of data, where the older drive choked completely. Max throughput peaks at 130mb/s... not going to get any better with SATA-1.
I am able to run many more apps at once than I was before. Partly this is due to having added 2GB more RAM (6GB total), but I am able to use 4GB of swap without noticing any major slowdown. The main place where I get slow results is when I start a new app when my RAM is full and I have used a lot of swap... I get lots of launch bounces and spinning beachballs in my other apps, as OS X juggles swap and RAM-based storage. This is only a minor annoyance, since I don't launch new programs all that much... I load often-used apps on login, which is also noticeably quicker.
I also can get slow results on file copying... I suspect this is due to overloading the SATA bus with simultaneous reads and writes, and may also have something to do with the v4 not supporting as many IOPS as does an m4, for example (it spec's out at 10K iops for reads and 4K for writes, vs. an m4's 45K/20K). An annoyance, but not a show-stopper. I get excellent results with video playback and VM loading (VMWare Fusion 5, Windows XP SP3).
In sum, this drive has been an excellent deal for my older Macbook Pro. When I finally upgrade to a new laptop later this year, I'll stick this v4 in as my encrypted drive for my home folder, and it should perform great in that role.
