Any user reports on Toshiba 5T or 4T drives (PH3500U or PH3400U)


Recommended Posts

I've had good luck with the 3TB Toshiba drives none of them have been DOA.  2 have died and one red balled but those statistics (~10% of my total Toshiba drive count) are slightly more than with my WD Red drives except I have had WDs DOAs. My Seagate's have ~15% failure rate with only 2 DOA.  Seagate is the only brand I've had that had a smart report that looked ok one day and was dead the next.  I even had one Seagate that was fine until I powered down the computer and when I powered back up it was completely dead - computer no longer recognized it.  My Hitachi drives are at about ~2% failure rate but no DOA's and are my favorite brand right now.

Just bought two 5tb drives recently,  both drives were not recognized by unraid.  Tried W7 and couldn't initialize the drive,  kept getting errors.  W8 machine wouldn't even see in bios.  RMA'd both.  Nervous about replacements.

Were they OEM drives or Retail boxed drives?  I think most of my DOA's have been because of bad packaging by the seller on OEM drives.  I don't remember if I've ever had a retail boxed drive DOA - I probably have but it is so infrequent that I just don't remember it.

They were both retail and boxes looked undamaged.  I guess I am just really unlucky [emoji22]

Or the quality of the drives have fallen.  My 3TB drives definitely used Hitachi technology because the first 2 drives had Hitachi firmware and identified themselves as Hitachi drives but were stamped with Toshiba.  They were obviously old stock that Toshiba bought when WD & Toshiba got together to buy Hitachi.  Now that Toshiba is manufacturing them for themselves (and 5TB drives are new and may be wholly a Toshiba design) the quality may have gone down hill.  HGST (the part of Hitachi that WD owns) appear to still be up to the Hitachi standard and at least in 3TB size Toshiba's appear to be as good as WD's Red line for the most part as far as reliability.  I just hope yours were an aberration because I was thinking about getting some of these drives myself.
