  • Larger Font Styles
    Guest:

    Just a quick heads-up that I've implemented larger font variants of our forum's light and dark page styles. You can select the style of your choice by scrolling to the footer of any page here. This might be more comfortable (it is for me) for those with high-resolution displays where the standard fonts, while permitting a lot of text to fit on the screen, might be uncomfortably small.

    (You can permanently dismiss this notification with the “X” at the upper right.)

 81  2.0TB WDC WD20EARS-00S8B1           103.7    96.5    84.0    69.8    44.2

 83   18TB WDC  WUH721818ALE6L4          253.9   250.6   225.9   184.0   114.6
that was first time run of readspeed ever on the HDDs, and the 18TB one was never used(ie. new)

- KINGSTON SA400S37240G is the SSD, the other two are the HDDs:
- WDC WD20EARS-00S8B1 is Western Digital Caviar Green 2TB and can only do max SATA 3.0 instead of 6.0 like the other two.
- WDC WUH721818ALE6L4 is HGST WUH721818ALE6l4 Ultrastar DC HC550 18TB, 7200RPM SATA-6Gb/S, 512MB Buffer (Helium Platform Enterprise Hard Drive, pdf datasheet here). I got this instead of WD Gold 18TB because of reading this: "I've tried WD Gold 18TB which is not very loud when doing something but it clicks every 5 seconds when idle due to PWL(Preventive Wear Leveling)." and I can confirm that this Ultrastar doesn't click at all and when it's reading/writing it kinda sounds like rain on the window sill and you can kinda feel the vibrations on the table, especially compared to WD20EARS(which you can feel none)

Here's hwinfo64 log for only the 18TB one(because this post can't be more then 10000 chars):

(for the other drives, the log is attached in the 2of8 zip file)

Some more details about the 18TB one, for whoever cares for more info, is in files and screenshots attached to this post as a zip archive(had to split the archive in 8 pieces or forum won't allow the upload(too big), they're numbered in the order of what I've done to the drive, timewise). (there are screenshots of HD Tune Pro, Crystal Disk Mark, Readspeed logs, hwinfo64, HDD Low Level Format Tool log which I think it was just sending zeroes instead of using format command, hence why hwinfo64 was able to see write speed rate as 260+ MB/sec)

unpacking all 8 zips would yields this dir structure:

Code:
01_readspeed
02_hwinfo
03
04_cdm
05_llft
06_hdtune
07_cdm
08_readspeed_again


Here's a few screens from the zip archive, for the 18TB drive:

ok I can't attach more than 10 files (8+2 pics), I may post a few more in next post.
