New Crucial M500 SSD

A

AlDrake

I have a Samsung SSD 840 (which is much smaller in capacity) and I am
very happy with it. Setting it up in the first place was a bit of a
challenge (which I regaled the group with at the time) but it was
worth it in the end.

I have about a dozen Crucial SSDs of the M4 flavor and find them to be
very satisfying. Now they have released this new variety which I find
very tempting and hard to resist. I am hooked on SSDs so I guess I'll do
it one more time.

Should I buy one now and start replacing my M4s? I haven't bought any
computer stuff in some time.

The M500 has a slight advantage on Sequential write. But only if
you're buying the 480GB or 960GB ones.

http://www.anandtech.com/show/6884/crucial-micron-m500-review-960gb-480gb-240gb-120gb

The table on that page, claims write endurance of the individual chips
is 3000 writes on the 25nm (M4) and 3000 writes on the 20mm (M500 128Gbit chip).
So the write endurance hasn't changed. It's possible though, that the change
in page size, might have an effect on write amplification. The page is
bigger than the 4KB cluster used in NTFS.

*******

Some day, we won't have to worry about write endurance. I read a blurb the
other day, where a researcher has figure out that "annealing" flash cells,
repairs the damage done by writes. But it will be some time, before the
idea of having internal heaters, will appear in practical devices, if at all.
Still, it's an intriguing idea.

Maybe ten years from now, we really will be able to treat flash drives,
like they were regular hard drives (no special treatment, defragment them
if you want, etc).

*******

As with any brand new product, wait three months for the eager buyers
to test them for you. If there are no overwhelmingly negative reviews,
buy one for a test drive.

Interesting, thanks. However I fall into the category of the eager
buyer. I have faith in Crucial. I haven't had one fail me yet.
