Pros: I wanted a fast but silent hard drive and couldn't afford a 1TB SSD. This Fit the Bill. It's as fast as my 2TB WD Black which is a 7,200RPM drive. Not bad at all. It's worth the extra price over the other drives in the same size. FYI my WD black is driving me nuts. It was SO loud.
Summary: This is really a neat option if you want a lot of storage and good performance but you don't want or need an SSD.
Pros: I bought this a year ago and delayed installing it because I had some room left on my old drive and I wasn't confident in cloning. I needn't have delayed - the cloning from my 512GB HDD was slick and quick using Acronis True Image HD. I went with an HDD since my computer, an Acer Aspire 5738-0699...
Pros: These little drives have been great so far. I was skeptical at first, buying refurb drives. However, after having these for over a month I can say I am very pleased and there has been no performance impacts I've noticed
Cons: Only one con, due to the design it is missing two screw holes for mounting in the bottom front. Just a pain, but do not change the hardware.
Pros: Received the hard drive on July 30 but did not have the time to use it, it is still in box and cushion. I will come back sometime next 1-2 weeks once I get my system on the hard drive and see the performance/result.
Summary: Also ended up fitting a Mushkin 128GB(wish that I'd sprung for 256GB now) msata which I use as the boot drive. System is a Sager NP8250-S. (NOTE: there is a 2nd msata slot on this model, but it is disabled because of design defect and IIRC this model has been retired and replaced w/the NP8255 which...
Pros: Fit the other hdd bay(7mm originally meant for an ssd) under the optical drive(IIRC).
Cons: Slow. The primary drive shipped with this notebook is a 7.5k WD black 750GB drive and this drive is ssslllloooowwww compared to that drive, but there's NO other choice for the 7mm bay other than a MUCH more expensive ssd.
