if i had a budget and need for multiple interconnected 24x boxes, id go for primary with enough external ports to handle any amount of drives comming drive drive_node/slave box and equip rest of the boxes with some extra cheapass board+cpu+ram to power local expander
using 6 cables to get 24x...
forget the pending sectors, you have 4000 realocated sectors, backup yr raid and dismantle it asap
that drive is gone
waranty is probably expired ( 20k poweronhours ) so throw it out
get hdd shiping box.

remove drives from server, pack em in the box and for the most part you should be safe.
back when i had 70+ drives at home, i ran spindowns all the time
power/heat savings made enough sense
+ i had proper indexing tools, drive was never brought online if someone just needed to clarify whats on it, they came up only on real datarequest ... and in those cases waiting 10-30s wasmt...
indeed
back in the '04/05 we needed at least 8 drives to achieve 1tb ...
today 10 is done with 3 and almost 50 can be done with 12, with is basicly a desktop design
we truly need 50-100TB+ thread
the case has 6 mini-sas ports
usas2 will provide you with 2 aka 8 ports for drives
you might wana look into m1015 @ ebay and new board with 8 satas onboard + 2 pcie or board with 3 pcie slots
id go for 3x 2tb
if needed 7,2krpm drive for sys/data/misc
and two drives for offline backups one localy and second preferably keep offsite, lets say work or neighbors/family place
going raid at home only pays off if you're interested in speeds, but today ssds have surpased that
about cooling google says they mostly don't need one, but that's another topic
currently i have ~90+ drives running, up untill 6months ago i was running most from home and spin downing didn't cause any issues or failures, over the years i've had at least 200+ drives, the few failures i've had...
that ram amount thing is for dedupe to keep table in ram
in case of file server for most cases dedupe is impractical and with 32g you should be fine
about those kingstons, have you found any 3.0 with decents speeds?
cause the normal 2.0 ones are slow 10/5mb tops
i have them on several servers...
not so sure about 100, but its truly time to seriously start thinking about 50-75+ thread
for crist sake you can get 10t with 3 drives, back in the day we needed 8+ drives to achieve 1tb!
for simple db pull, latency is your issue, not maximum bandwidth
for ssd, if he realy wants it: id go for any smg/intel aka non sandforce ssd for the most reasonable price
for backups: RAID1 is not a backup! Backup is wol'ed servers in other side of country with scheduled rsync to them! :D
if...
normaly such "smallish" bulk orders can get only retailer and smallish wholesaler discount, 5-15% tops
wholesalers need 10k+ (of drives) orders per quarter to even get direct line to manufacturer, anything else gets addons from numerous wholesalers in between you and your retailer, getting...
^^
multiple thousands of dvds/blurays just doesn't make sense anymore
file server gives you decent availability all over household and wherever you can reach it via internet
i had 4220 running verticaly for a time, no problems
but be sure you have it leveled, norco has poorly designed backplanes and even more poorly made structure, mild shifts in cases angling will make hotswaping yr drives problematic, several times when i pluged in first drive into backplane its...
well in that case, as long you dont mind having 4 drives giving ya just 1,5tb, go for yr idea
though, if yr network speed aint the best and yr playing alot, be carefull about r0s and steam, takes great time to redownload 200g worth of games when yr on sub50mbit line ;)
in most cases todays 7200rpm drive will be faster then 5y+ old 2x160g r0
even if the 1t you have is 5[4-9]00rpm for safety and simplicity of yr setup, id go with ssd+1tb ... and get rid of those 160g while hdds have some worth due to year old shortage
kinda not clear, 100k eu is for startup, 250TB data, right?
so if you go for 400ish raw ... 4x 45x sm jbods 8k eu + 180x 3TB 27k eu = 35k for data
should leave ya with more then enough for networking and two headnodes
im pretty sure only ones from norco with atx support are cases above 3u
id realy love to go for couple 2u 12x cases ... but 2u psu thing keeps me away.
even for 3u keeping it cool and quiet will be hard, you'll need to replace stock 80mm fans with some high performance silent fans ... but...
norco 3u 16x should do the trick, though, with atx psu its matx only
id go with 4u 20/24x for a couple simple reasons
1) 120mm fanwall
2) more ports for the buck
yes
rma drive if possible
remove from any raid/pool whenever possible
in the mean time monitor reallocated sector count ... if it comes up make its removal a ultrahigh priority
and ... expect datacorruption
^^^ even with the shiping and import taxes, there is no simpler/cheaper way howto get a sas jbod
sad truth is any expander or even decent case will exceed that price in no time
and thats not counting psu or cables

the thing is, if you are looking for smth from 1,3k to 2,1k ... then sm is right in the middle with doubled density and superior quality
didnt notice the count, seems like 25, pic i found on google cause i was too lazy to take a real picture of box standing next to me :P
all of mine are 20x
got one i specialy like from smg, holders for plastic drive packings, not like wds/sts baredrive only
with large orders you get these
over the years ive gotten several of them, never tossed out, left them on my shelf just in case i have to dismantle some fileserver
