"This is a low cost low end SSD that ultimately I should have known better than to purchase.Despite the initial speed boost and the excellent cost/size ratio of the initial purchase (I did happen to buy it out of desperation due to a mechanical hybrid drive failure) this product slowed down incredibly quickly and even started to impact the start up and shut down times of my PC. Going from five second up time/down times to sometimes several minutes as time went on.This morning when I went to work, it wouldn't start up at all, and sat for over an hour on the BIOS loading screen before I simply gave up and started trouble shooting given how this has been a slowly worsening issue.After following the usual steps, a clean up, a step by step removal and restart to see where the problem lay, nothing would touch the issue- until I remembered I'd slapped this little monster on the side panel of my case and decided to unplug it.Immediate start up from the boot drive, back to factory fresh.If you're just making a terrible office PC that you want to pretend is high end to scam people into buying it on ebay? Get these in abundance. If you're a genuine product user that wants to actively play games, use any program of substance or want a product that will last you more than twelve months? Just trust me and settle for a name brand like Samsung EVO. The cost cutting isn't worth the head and heartache."

Good budget SSD that gets the job done with decent sata speeds as expected. Was easy to install as someone who knows how to already but came with instructions for those less experienced which is always nice.
