Default O.T. Spare HD

I have a Dell XPS 8500, with Windows 7
Professional, SP1, with Spywareblaster,
Malwarebytes, Avast, Windows Defender,
and Windows Firewall.

(1) TB HD
Intel (R) Core (tm) I7-33-3770 CPU @ 3.40 GHz
RAM 12.0 GB
System type: 64-bit operating system

I also have

a Dell Opiplex 780 tower with Windows 7
professional, SP1, with Spywareblaster,
Malwarebytes, Avast, Windows Defender
and Windows Firewall.

(1) TB HD
Intel (R) Core 2 Duo 2.93 GHz
4 GB RAM, 750 GB HD
System type: 64-bit operating system


external hard drives:

Seagate backup pls (1) TB 2.5 USB portable HD

WD Black series WD2003FZEX 2 TB 7200
RPM 64 MB Cache SATA 6.0- Gb/s 3.5"
Internal hard drive.


I posted this on another thread:

Recently I went through a power outage
and the repair electrician wired my mobile
home for 220 instead of 110 and fried allot
of electronics.

Luckily the computers were not effected
directly. However, it got me to thinking;
what would happen if my 780 HD crashed?

This isn't something that is critical or
has to be taken care of immediately but I
do want to resolve it after I take care of
more pressing matters.

I've prepared for that with the 8500 with
two spare HD's, each which has been already
set up to boot.

However I don't have anything set up for the
780

Look into RAID 1 if you just want to deal with a drive going bad. You
can RAID your C: and a single drive failure will be pretty
transparent. You snatch out the bad one put in a new one and it will
sync up itself.

It's really really hard to pick hard drives now.

There don't seem to be a lot of reviews on Newegg.

You can look at the latest BackBlaze results.
Some of the drives are too old to find comparable models
for sale now. The DM000 for example, I think I have a couple 4TB
of those, and for Seagate I was impressed with their
"lack of the usual flaky Seagate behavior". You can see
in the BackBlaze results, that not all Seagate models
are created equal.

https://www.backblaze.com/blog/hard-...rates-q3-2017/

Now that both of your computers run Windows 7, there is no
longer a need to limit yourself to 2TB drives. If you want
to look for, say, drives with good results in the 3TB category,
you can look in there too, and when they show up, in
Disk Management you can set those to "GPT" instead of "MBR".
I won't suggest anything larger, due to the pricing. Selecting
a $500 drive, means all your eggs are in one basket in terms
of a "failure model", and I'm still not all that comfortable
with gigantic hard drives. If I could afford to buy two or
three or four of the big drives, then I could have multiple
copies, and if one drive died it wouldn't be the end of the
world. But $500 drives cause indigestion of the financial kind,
so that's just not going to happen. The 4TB may be the
sweet spot, but they're also kinda heavy. Anywhere between
2TB and 4TB is probably good - the customer reviews will
tell you a lot (i.e. "noisy drive").

If you go large enough, some of the large drives are Helium
filled, and no longer have an air breather hole. The only
problem with this, is the intended life cycle is 5 years
for Helium containment. They should hold their Helium for
5 years, but it's not clear (on average) how they perform
over longer lifespans. Both Seagate and WDC have Helium drives
and those have slightly lower power consumption. The frictional
losses in Helium are lower. And the sealed HDA means there
is no possibility of foreign contaminants getting in.
(I like this idea a lot, because it means the room humidity
can go over 60%, and you don't have to worry about that drive.)

If your house flooded for example, you have every right
to expect a "washed and dried" Helium drive to continue
working. Whereas the air breathing kind (all that you and
I own), they're not safe to immerse in water, because
the breather hole could admit water into the HDA
depending on the barometric pressure that day. The old
drives needed to run at atmospheric, and the breather hole
ensured the inside and outside of the HDA were at the
same pressure. The breather has a hepafilter on it, to remove
dust and smoke, and only the tiniest molecules can make
it through the filter.

While I'd like to, the Newegg comments are too short and
full of rubbish, for me to say anything that would
add value to your disk selection exercise. When the review
column has too few comments, it's called "not statistically
significant" and we cannot draw a conclusion.

Good luck,
Paul

I am a firm believer in having several external drive backups.



Though this has only happened once...I had a PSU take out both internal
hard-drives at once. Fortunately it was a a non-critical machine and all
was backed up anyway.

I didn't realize that picking HD's was
difficult now? You would think the opposite?

I believe the HD I selected is the one
we choose when creating back up drives
for the 8500. We first choose the WD
but that was too noisy so I made it my
External HD.

https://www.newegg.com/Product/Produ...82E16822236624

As I remember, you thought the 2TB HD were
better than the 3TB HD's, so we went with
the 2TB. I still have 794GB of free space
on my HD so it's a good choice for me.


This is the 780 external HD:

https://www.newegg.com/Product/Produ...82E16822178107

So if I buy the Seagate I'll have to buy
another case for it as well:

I tried to steer you to 2TB drives, because one of your
computers used to have WinXP, and I wanted all your gear
to work "no matter what".

Now that your WinXP machine is gone from the picture, that
constraint is removed.

You don't need to buy a bigger drive. I'm mentioning this
only as a means to open more opportunities (like if a 3TB
drive happened to be on sale or something).

*******

The Startech external enclosure doesn't look available any more.

There's a Rosewill. RX358. Apparently it lacks rubber feet.
I don't know if there are any rubber feet kits with good
adhesives. I like something of that nature, to make it harder
to knock the unit off a desktop surface.

Regarding the Seagate drive, the Reviews have a lot of 1 egg
reviews. But since the drive is relatively cheap, perhaps
if it lasts three or four years, that's OK. It's hard to
find reviews, where the 6TB reviews aren't mixed in with
the 2TB reviews, and then you don't know what the overall
statistics are telling you. Even Amazon does that, mixes
the reviews together like a bad kind of soup.

I think we matched the computer drives
extremely well and they do work no matter
what.

I can only go by my own experience with
Seagate which all have been good but
perhaps it's best to buy sooner than
later given that the market is becoming
more difficult and hard to find quality
products.

I would of thought the opposite but such
does not seem to be the case.


Thanks,
Robert

The ST2000DM006 in Canadian dollars here is $80.

How do you hit a price point like that on a precision
engineered item ? You have to cut corners somewhere.

I can't really tell you why those drives break. I
read somewhere that the flying height was 3nm, but
as to whether it's that low now, there aren't
a lot of web pages with detail you can trust.

Some of the Seagates seemed to be showing a "wear"
pattern, as if there was surface wear.

The flying height over the years, has gone
from 10,000 nm to 3nm. Sooner or later, that has
to have consequences. You can only polish the
platter so flat - and reduce the NRRO to
a certain level, before the flying height
becomes an issue.

These companies want to use the same platters in
all their products, for mass production reasons.
That means the recording density is high.

I don't think they actually achieve that. The
15K drives used in servers (very noisy), I think
those use a slightly less-dense platter, and the
stroke on the arm might be shorter. Some of those
drives read at 300MB/sec. But they're not the kind
of drive you want in your living accomodation.

If you can get this document open, take a look
at the disparity between the lower capacity
drives and the upper capacity drives.

https://media.flixcar.com/f360cdn/We...879-800074.pdf

12TB... 8TB 6TB...1TB

7.0W power 9.3W...7.4W
20dB 29dB...25dB idle
-- Same noise level on seek --

That means there are some design differences between
the big ones and the small ones. And the big ones could be
Helium filled. I think it's possible (and has been done
for the last four or five years), to make air breathing
6TB drives.

But because they don't tell us the seek time on the
drives, it's not possible to tell which is "ripe for pickin".

There were the drives with the shingled write pattern,
which had simply horrible write performance, and those
were "never fit for pickin". They still buy those for
cloud storage though. BackBlaze doesn't use them, but
I bet there are some other outfits who do. Archive.org
couldn't afford to use those, because they need all the
speed they can get. For cloud storage though, the upload
rate is probably slower than the download rate.

Between the running drive, and your new cold spare though,
you will have a bit of redundancy.
