Cache 3.5-Inch Enterprise Hard Drive

I bought mine from GoHardDrive by selecting the Amazon seller. If you know how to read SMART data (as long as the current column is _GREATER_ than threshold column, it's healthy), skip this review and look at the pictures. If you don't, then proceed to read the rest of this review. To test this drive, I did 10 64GB read/writes with CrystalDiskMark. I took pictures of the SMART data before and after. Other than a slight increase in temperature, I didn't have any changes in the SMART data, which tells me this is a good drive. Let's start with the bad. Most people would shriek in horror at the drive having a 4.5 year power on time. But since the drive hasn't had any errors, 19 spin ups, this tells me the drives weren't really used that much. After all, did I expect a brand new 6TB hard drive for $67? Of course not. Would I trust this more than a refurbished Seagate? Absolutely, HGST is pretty reliable. (If you don't believe me, look at Backblaze's HDD stats.) The good: Cheap Surprisingly quiet SMART data is clean and healthy SMART data wasn't reflashed -- GoHardDrive appears honest The bad: Long Power On Hours (4.5 years) That being said, should you use this with important data? Probably not. Only use this if you need a cheap drive.
