Hard Drive, SSD or regular
Looking on crucial.com at SSD's and noted that all the recommended ones -this after they scanned the system- seemed to be 2.5 inches. The drives in my laptop are more like 2.75". They said that would not be a problem but I have to wonder. Anybody got an opinion? |

They said that would not be a problem but I have to wonder. Anybody got an opinion? A laptop uses 2.5" drives. I gather from reading the dimensional information in this article, that the "platter" is 2.5 inches, and the exterior packaging has some other dimension. You could well be right, when you tell us you see a 2.75" thing. I haven't spent too much time using my measuring tape on them :-) http://en.wikipedia.org/wiki/Hard_disk_drive Drive sizes are 1.8", 2.5", 3.5", 5.25" (we'll ignore the bigger ones I've played with in the past, such as 8", and the machine with the removable disk packs). A 1.8" drive would slosh around inside the laptop bay. The 2.5" should be a good fit. Desktops can have two sizes of bays, and you can either fit a 3.5" in a 3.5" bay, or using a "rail kit", fit it in a 5.25" bay. Optical drives for desktops, are 5.25". The 5.25" bays also use slides, which come with the computer case parts kit. ******* A critical dimension for a laptop owner, is thickness. The 2.5" drives might come in 9.5mm or 12.5mm thick. Sometimes, a user will come in here, and report they got a 12.5 by accident and it doesn't fit their 9.5mm deep bay. (In some cases, you can grind some excess structural plastic out of the bay, to make room, but I digress.) SSDs can be even thinner than that, such as 7mm. If you buy a 7mm, and if it has screw holes on the side, it might still fasten to the metal tray they use in the laptop. With a little forethought and research, the mechanical details of your purchase, won't be quite as much of a shock. ******* The tiny 1.8" form factor, uses a microSATA connector. When it comes to SATA drives, the sizes bigger than that, all use the same standard. Whereas, at 1.8", there is a smaller connector. An adapter cable is required, and some buyers discover they have to buy the adapter cable from a different company than their drive. So if you see any "bargain" 1.8" drives, don't forget to include the cost of cable and shipping, in your budget. The drive ends up not being quite as cheap as a result. (And if you sit it in your laptop, it might need a small adapter kit to hold it in place in the tray. I haven't researched that part.) Mounting SSDs in a desktop is easy. Just use a nylon tie, to fasten the drive to any available "post" in the case :-) http://en.wikipedia.org/wiki/Cable_tie Paul |

It is a Seagate ST1000LM010 or also known as a FreePlay 1000gb. Gee here are 15 of them I just found right here below. I am sure it isn't the only 2.5 inch 15mm drives out there. http://www.ebay.com/itm/350585693057 -- Bill Gateway M465e ('06 era) - Thunderbird v12 Centrino Core2 Duo T7400 2.16 GHz - 4GB - Windows 8 |

And I notice your Ebay item, there's no warning about it either. I bet that's caused a few unhappy customers. Paul |

I just don't want to have to return something. I have been using Crucial for about 10 years and their products and service has been excellent but when I don't understand something I ask questions. I don't want to wish I had later. |
