      • Can also be plugged into a USB-SATA converter
      • Fast storage to replace HDD

      What a piece of cake to convert my slow HDD to very fast SSD in the laptop. Simple instructions, plug-and-play. Acronis software to clone the HDD to SSD was free, included, and easy to use. Can't get simpler. And very fast now!

      Acronis cloned my old hard disk and within 1 hour, I was speeding along. It is a little intimidating the first time you do it, but I have now replaced every C drive hard disk in all 5 of our laptops and desktops with Crucial SSDs.

      Purchased and installed in a Dell 15-5000, 5567. Cloning went well, installed with a memory upgrade. Booted up fine, seems to be working well so far. And it's really fast compared to the regular Toshiba hard drive.

          • replacing old, much-used HD with a newer, faster

          Had the item professionally installed, and old HD mirrored/cloned with no loss of programs/data. Seamless process that cost me $40 total; total of 1 day at the shop. Old HD returned to me. Dell Inspirion laptop with I3 chip (8GB RAM) is noticeably faster, particularly during large downloads. Day-to-day, undemanding usage is a tinch quicker. Altogether, a worthwhile upgrade.

          Acronis True Image for Crucial was easier to use than I thought. Have older system speeds up nice, virus scan takes half as long. Easy to setup.

          I had a couple 120 gig crucial drives just needed more storage; I have a hyper-v setup on and old spinny drive from WD, way old, and slow, put in this new Crucial Drive and then striped my 2 120 gig Crucial Drives together and my system is so fast and enough space to do anything I'll need. And the 2 120 g drives are still functioning perfectly after 4+ years
