of Vantec external cases for 2.5" SSDs, and for the USB cables providing<br>
power to those enclosures (and possibly also for the eSATA data cables,<br>
though we don't have any suspicions about those cables' reliability), so<br>
how about I start with acquiring current, larger 2.5" SSDs?<br>
<br>
/me looks at <a href="http://newegg.com" rel="noreferrer" target="_blank">newegg.com</a>, is appalled at how junked-up the site now is.<br>
I'd heard they had new management. Ugh, it shows.<br>

Current mass storage is a mirrored pair of Samsung SSD 840 PRO Series<br>
256GB, best of breed for their day, notably using MLC NAND flash rather<br>
than cheap-ass, slow TLC (triple-level cell) NAND, the greater quality<br>
attested by the 5-year (now expired) warranty rather than the commodity<br>
sludge's shorter warranty. Cost was about $1/GB when new.<br>
<br>
Looks like, in the 2.5" "traditional" (heh!) form factor, as opposed to<br>
racy M.2 stuff that is not a go for the CompuLab box, the Samsung SSD<br>
860 Pro Series, in several capacities, is a recent successor to the 840<br>
PRO Seriea. <br>
<br>
In 1TB sizes, Newegg offers new for $520, used for $200.<br>

Except this is not being sold by Newegg but rather _through_ Newegg by<br>
some other clowns named "The Best Deals for You Store".<br>
<br>
I am -not- getting warm-fuzzies about 2024's iteration of Newegg. Where<br>
_do_ people shop for reasonable deals from non-flaky firms, in 2024?<br>
Central Computer in Santa Clara, maybe?<br>
<br>
<br>
Anyhow, that troubling detail aside, suppose I were to buy a pair of 1TB<br>
SSDs and 2.5"-compatible external cases plus power ("USB") cables for<br>
them. Then, we could put guido into degraded-RAID1 mode with just one<br>
of the 256GB drives, booting from that, and adding one of the 1TB drives<br>
to the system, then set up a new guido on the 1TB drive (with LVM and<br>
other changes deemed desirable), migrate everything to it, set the 1TB<br>
drive to be bootable, power down, remove the 256GB drive, add the second<br>
1TB drive, power back up, remirror the RAID1 array.<br>
<br>
I'm used to doing that sort of thing with not only all services offline<br>
but also and in single-user maintenance mode; don't know how you feel<br>
about that. System being down for an afternoon is perfectly fine.<br>
<br>
At that point, we'd have a lot more space to play with, and LVM if you <br>
really think it's justified. Personally, I am not convinced about the<br>
need for that additional abstraction layer, especially if one has enough<br>
spare space, and also if necessary is willing to have downtime while<br>
moving around data and remaking filesystems (which I am willing to<br>
have).<br>
<br>
What do you think?<br>
