Defrag not your SSD

Saw this. Looks like a bit of hair of the dog for applying to your
SSD, so far as TRIM is implemented, a "regular" convenience if, at
all, adjustable. Without such regular TRIM intervals judiciously
applied, of course, there comes a point when even a SDD's write speeds
would mire itself hopelessly in sludge. That short of a clause
couldn't possibly imply other than TRIM support to an otherwise
platter defragger.

And however you intend to use the program, you'll appreciate design
details like the clear, easy-to-use interface; the excellent defrag
scheduler; the SSD support, using regularly scheduled TRIM commands to
improve write speeds; the Explorer integration (defrag any file or
folder from a right-click option); the notebook support (defrags are
optionally disabled when you're running on battery power); and the
ability to run defrags before Windows loads, allowing the program to
defragment system files that would otherwise be locked.

Sounds like a bunch of snake oil. SSD's do not need defragging, as there
are no physically moving parts in them. Overusing the TRIM command will
only result in over-wearing it.

Overusing trim, hadn't heard that but makes sense if there's plenty of
free space. Snake oil sounds about right. Have to look over software
carefully these days. They'll say anything to sell someone fresh
snake sludge in a box.

The TRIM command was implemented so that the operating system can inform
the disk hardware when it's expecting the disk hardware will remain
relatively idle, so that it can begin its internal maintenance. All disk
activity gets initiated through the OS, so it's only the OS that should
make the decision as to when to send the TRIM command.

Unless the onboard SSD controller has no suitable counterpart to a
TRIM provision for such contingencies when used in an OS, such as
mine, without TRIM support. Seems somewhat varied in practice,
accounting developments, from earlier recommendations for moving the
data elsewhere while formatting the SDD 'two or three times a year,'
to whatever is on a disc provided with my SSD, presumably a TRIM-like
utility, given the appropriate OS service pack updates I haven't yet
adapted for a closer look. It's actually on the Samsung SSD
operational PDF manual, I briefly looked over - pretty sure I saw a
mention of their TRIM counterpart utility for XP.

How old is your SSD?

It's not so much that it's expecting the disk hardware will remain idle,
but rather, that certain blocks aren't needed anymore and can be
scrubbed now (rather than waiting for a re-write event in the future,
which might hurt performance)
 
That's a 64GB SSD, which is ancient in today's terms. My assumption is
that it doesn't have one of the modern SSD chipsets, such from
Marvell/Sandforce. The chipset has to support the TRIM feature, and my
guess is that this particular version doesn't support it.

No, it's a modern design, relatively. It's just been made obsolete by
the newer 840 series. It doesn't use Marvell/Sandforce but Samsung's
propriety design using a triple core processor. It does support TRIM
but look at the performance specs, it's one of the fastest ranges
around.

Interesting. I saw something about TRIM in the included software
utility disc (min: WinXP SP3). Just haven't installed that build, the
SSD is in, yet for replacement of this computer - an old 478 P4 for
updating to and old 775 Pentium dual core. I went with the Samsung
brand, how I was reading it, among top SDD construction considerations
"par" to IBM. Imagine it'll involve a fair amount of customization --
I've always run programs apart from the main OS partition, on separate
partitions -- and base any subsequent OS binary image backups for the
program drive links (after tested for familiarity and acceptance).
Relatively quick and relatively small OS partition, as the program
drive doesn't need to backed up near as often. Anyway, this SDD will
become my new program drive with the exception of programs doing self-
contained writing (logs or or whatever else which can't be defined
under preferences for elsewhere off the SSD). Never had two program
drives before, but that'll be the end effect, a supplement to the
SSD. Won't be a "speed" thing, though, in the sense of everything
operable going on, normally, C:\Windows.
