  1. The SEAGATE 2.5" 15mm thick 3TB and 4TB drives are BOTH PMR and have 5 platers and 10 heads. As for 9.5mm thick drives, there's only one with 2TB, that no matter officially many places sell as a Seagate drive, is actually a Samsung drive...AVOID this drive. It's problematic with LARGE tendency for sooner than later start to make all kind of noises. This drive is not SMR but it doesn't seem to be a pure PMR either...Samsung have this drive also in 1.5TB capacity but using standard 500GB platers and PMR heads that, according to the rare info i had read about it, seems to work well w/o weird noises. Both are 3 platers and 6 heads. Finally, Seagate have a new 7mm thick 2TB drive with only 2 platers and 4 heads but is SMR, no reviews yet. There is a supplier in EU with all them in stock has bare OEM drives.
  2. Any chances of a review, in special of the unencrypted 2TB version ST2000LM007 ? I'm curious about what would be performance of such a SMR drive, if possible with a OS installed, compared to other HDDs that are PMR.
  3. Brian, i made this same question about the Samsung: Did you tried to open the drive to see if its possible (yeah i know, goodbye warranty) to see if USB bridge is soldered directly in the HDD PCB or if drive still uses standard SATA connectors ? TIA, AJSB

  5. That's great news ! If you can/want,. also try to install an OS in it and use it for some hours to check if the drive makes chirping and/or beeping noises. M9T do it sometimes, in special when NOT under load (not related with head parking and/or eco low power mode(AFAIK). OS type or file system is irrelevant, M9T exibits same behave in XP, 7, 8.x, 10 or Linux, and, in NTFS, ext2, ext3, ext4, XFS, ReiserFS, etc.
  6. The actual HDD is made by Samsung w/ 5 platters in a 2.5" form factor...not sure if is 15mm thick or 16.5mm but might be 15mm. This gives a platter density of 800GB, witch compares well with Toshiba model of 4 platters and 3TB, 750GB per platter using PMR. So, i have hopes that this HDD also uses PMR and not SMR. The big question is if the HDD have the USB interface build-in the HDD PCB or not. For Samsung M9T, there are both versions...the external version sold by Seagate, at least for now, is a traditional SATA drive w/ a microscopic USB bridge then inserted in the SATA DATA/Power conector. But the external version sold by Samsung itself uses the USB bridge soldered directly in the HDD PCB. This gives an advantage to the Seagate version that allows pop out the drive from the enclosure and use it in SFF builds or Notebooks...at cost of loosing warranty. I hope this new external HDD from Seagate also allows that so i can use it in SFF builds. ....and i also hope they solved the chirping/beeping noises of the M9T when we install a OS on it....flaky firmware
