Any mechanical hard drive that go like the wind?

Hi All,

I have a customer who really, really wants RAID 1.
(She is well away of the difference between backup
and RAID.)

Problem: no TRIM support for RAID 1.

Are there any mechanical hard drive that go like the wind
out these? Sort of like a (poor) substitute for SSDs?

Many thanks,
-T

Any 3.5" 7200RPM drive does about 900MPH. That's a pretty fast wind :-)

Neither could I have.

In a former life, I had to deal with customer requests for product
improvement. If I asked what they wanted, the answer was always, "more."
Didn't matter what it was, they just wanted more.
When I asked why, they had no idea why...more is better.
Often, a better approach to doing things was cheaper and more effective.

I have a 3.6GHz. P4 with a pair of 15KRPM drives in RAID.
Back before it was obsolete, I ran some experiments against a similar
machine with a 7200RPM drive. Sure, I could construct a benchmark
that showed bigger numbers, but sitting at the console, I really
couldn't tell much difference. One thing that did go faster was
the little wheel on the utility meter.

If the program is small enough, maybe a ramdrive would help.

Hi Mike,

I always go for the 7200 units, as they seem to have
a much longer lifespan. And, I also haven't been
able to tell a speed difference.

I was hoping to get something that approximated
and SSD drive.

I searched my archives, but couldn't find it.
There was an article on the web whereby a guy took a big
hard drive and managed to reformat it so that it thought it
was a 300MB drive at the fastest part of the platter.
He claimed it had performance equal to a more expensive Cheetah
15K drive.

You can get them. They're called hybrid drives, and are mechanical hard
drives with some flash memory to act as a cache. They provide roughly
75% of the performance of an SSD.

Hi Mike,

I have been told that the reviews counter that assumption.

Do you know of a trusted review?

Yes, try out the hybrid HDD's, which include both a mechanical portion
and an SSD portion. The SSD portion is nothing spectacular, only about
8GB, but good enough to cache most of the important Windows files, which
get used the most.

BTW, even if there isn't support for TRIM through firmware RAID,
Windows' software RAID should have full support for it.

Software RAID should be just as fast as firmware RAID, and more portable.

That is a 15K SAS drive with SSHD inside. Uses 32GB Flash.

The Newegg listings in the past for anything related to
SAS, always seemed to list problems.

Drives are $500 a piece.

Hi Yousuf,

Thank you for responding.

I could only find TRIM supported under RAID 0, not RAID 1.
Am I missing something?

Thank you. I have a lot of reading to do.

I used to go for 5600 (or was it 5400?) ones if I could find them, as
they seemed to me to run noticeably cooler (which obviously contributed
to the lifespan) - but I don't think anyone makes those any more,
they're all 7x00. It wasn't as if we were talking an order of magnitude
difference, like doubling RAM or more cores in the processor, and any
time where HD speed comes into play, there's such a slow-down anyway
that a less-than-50% ratio didn't make much difference. (Obviously it
would in some applications/systems - video processing comes to mind -
but if you're using those, you throw more RAM, and/or go SSD.)

I was hoping to get something that approximated
and SSD drive.
