which transcend ssd is this? how's your computing experience with transcend ssd? it looks good enough for common usage. (the write part is slower but i think as long as reads have enough speed, then you should be fine)

plextor's ram-based cache is relatively impressive. although it's not as good as ramdisk, and we don't need that crazy speed for everyday use, it looks better than samsung's rapid and primocache.

cheap low costing, and much better than kingston v300 (after changing to slow nand flash), and no provisioning on ssd340.

the fw update method quite dumb on ssd340, will wipe off the drive data sweat.gif

guess ssd340 no longer available, ssd370 now. ya, for laptop purpose it fast, cheap & good enough, though the 256GB model will double the 128gb write speed.




those scary high speed ssd really good for big large fast require database like tesco/mydin.

I just read up about Plextor's PlexTurbo implementation and the difference between it and Samsung's RAPID.
It seems that Samsung's RAPID is a write-back, which only writes to the SSD when a flush command is issued
while Plextor's PlexTurbo is a write-through, which will writes to the SSD when modification is still commencing.... can't find the correct word to describe it sweat.gif

and it seems that the difference is in the implementation nature itself, rather than the difference between implementation technique... hmm.gif

write-through improves data integrity but write-back improves performance (as only when write is committed then only it writes to SSD)

nice smile.gif to reduce os and app load time, read speed is more important. this is a good choice to go for if budget is a concern.

oh they have a not-so-good firmware upgrade process. still, i think it's not a big deal, as long as they can deliver proper updates hehe

ah my comments about plextor's plexturbo was based on speed found on images only hehe

yeah.. maybe all implementations ram-cache with write-back (i think it's deferred write-back) are slower for some reasons. i'm not really familiar with it. for the purpose of ssd optimizations, my personal preference is still write-back.

hahah.... no worries, i also learning to see what are the technologies on offer by the SSD manufacturers because you know,

makes our purchase "wiser" laugh.gif


btw, just found out that Plextor's parent company is Lite-On.... kind of shocked sweat.gif sweat.gif

they are the same ssd (pcie 2.0 x2). item 1 is the bare m.2 drive, while item 2 is the same drive mounted on a pcie adapter for compatibility reasons (so that it can be used in mobo's without m.2 slot)

in terms of speed, they are the same.

Oh, I see.

Its only PCIE 2.0 x2 only ?

I thought because it is very fast that it is PCIE3.0 and x16 just like Graphic Card slot....smile.gif

yes you can verify that from their product flyers. it's slightly faster than sata3 but yeah not really fast hehe

haha we can use pcie slots to access it but it doesn't necessarily use up all of the pcie lanes.

2 sata3 SSD at RAID 0 is faster than 1 M. 2 SSD?

for now, yes. currently this is the better option to get speed and to free up pcie lanes for better use (like gpu sli setups).

every now and then i heard people discussing about using PCIe lanes or not enough PCIe lanes etc, those are conditions IF you are using SLI setup right? other than that, i think your PCIe lanes are pretty much still have some left used most of the time?? hmm.gif


RAID 0 is fast, but doesnt that also means it is very dangerous if something happens to your file? As it will be rendered totally useless....


and also i want to ask, does using SSD with a not-so-stable voltage (for example, living in an area where there are suddenly electricity outage every once awhile) will brick the SSD?? hmm.gif

it's not just about multiple gpu setups. it depends on the purpose of that rig. there are some pcie-based stuff, like sound, video capture, nic, wifi, and raid/sata/usb/scsi cards, that can be added to the system to cope with needs. pci-e slots can also be used as a means to replace faulty integrated parts of a mobo.

mainstream systems (like 4790k, z97) usually have less pcie lanes than high-end ones (like 5930k, x99).

due to such limitations, different implementations are adopted by manufacturers to assign and distribute these resources that involve lane sharing (that means there are differences in the number of pcie lanes connected to each slot, something like this, http://www.tomshardware.com/reviews/best-i...oard,3902.html). it's important to check out the mobo manuals and review sites to know more about this, then plan your rig setup ahead before purchase.

we all know the risks of using raid0. we cannot eliminate them, so just prepare for the worst:

1. use it as a boot/software drive, not storage. normally 2x 256gb should be good and large enough.
2. make sure you can recover from disasters, by keeping the latest system images outside the system. (it's much more time saving than doing fresh installs from scratch everytime)
3. store the data in hdd (non-raid), or nas.


bad power supplies will cause damage in electronics. it's better to use UPS in this case. (it's not just about ssd. every component in your rig will be affected and i don't think you wanna risk them too) laptops are relatively better. they have built-in battery for this purpose.

oh... that one i read before regarding the PCIe lanes allocation for z97 chipset, i think is 20 lanes, and then x99 is 40 lanes, for maximum of 4x SLI config of 16x 8x 8x 8x... hmm.gif hmm.gif


I see.... my area is really bad in terms of power stability, every once awhile will blackout for like 5 mins, then return to normal, that sudden voltage surge is very damaging to my PC... >.< and yea, plan to get an UPS for the peace of mind sweat.gif

i believe it's 8x 4 times. nevermind my main point is that we must plan the setup accordingly so that we can use them optimally.

man that's bad. i think you should also get power surge protectors to provide additional protections if it's frequent.

samsung models that have msata version is 840/850 evo. i think you can find that at garage sales (ronaldjoe maybe?)

you can try out transcend ssd 370. there might be something worth while in garage sales also.

already asked him.. he said no stock.. i went to Lowyat all also said no stock...just curious is it changing model already?
is the 840 evo already phased out for msata?

oh ok. yes 840 evo has phased out and the new one is samsung 850 evo.

i think there are other options like crucial and plextor. however i am not sure if they are still available.

crucial no feeling towards them...
i only thought about plextor and samsung...

btw just curious.. is there any website regarding SSD/mSATA similiar to gsmarena? something like telling the date birth of each ssd/msata? just wan to check when is cycle of new model out

haha.. the 'numbers' of crucial drives are not among the finest, but they are ok actually smile.gif

as for release dates, i usually just use google or refer to manufacturer's website. i am not sure if there is a website with such functions lol
