Summary: Ordered this drive in February and it is already bad!! I just tried using this drive for the first time and it is defective. I ordered it back in Feb. but just now went to install it and it failed the clone. Clone verification said to run check disk and it found bad sectors. Now I am stuck with a drive that is no good. Will try to see if Seagate will replace it.
Summary: I have about 100 multi TB (2 to 3 TB) hard drives from Seagate, about 50 SSDs from various manufacturers. This is the first hybrid drive that I have purchased, installed and used and I was quite curious to give one a try. I had read the reviews about this model and it performs as stated. The device performs better than a plain hard drive but it of course is no where near the performance of a SSD from SanDisk, Micron/Crucial or Samsung, etc.
Summary: Recently installed this drive in my 15 inch mid 2009 macbook pro . Installation was a breeze. I was able to replace my old failed drive with this one in around 20 minutes. My laptop now boots to desktop in under 30 seconds. The drive is quieter than the original, and has noticeably improved the performance of my laptop. I highly recommend this as a replacement drive for your macbook pro.
Summary: I am not sure why everyone raves about how fast this drive is. I have seen no performance increase over my old, standard platter drive. I understand this is hybrid, not SSD, but there should be some measurable difference. It is significantly more noisey however. Actually, all of this is not relevant because the drive only lasted 10 months. The compujter will not recognize it, the drive simply "clicks" when powered on.
