60+ i think. The brand is hotway rock mobile disk. Outside the box it terang terang states that it supports uasp hehe

yeah. people misinterpreted without proper understandings. it's like many user comments, they don't actually check the 'when' of scenarios. the original author talked about what happens at the end-of-life of a ssd. the rest of the world thought it happens just like that.

i thought i was dreaming just now. after several tests, i think it's real. this is the transfer speed when i do a transfer from my computer to an external ssd (in a hdd enclosure with uasp support. ssd to ssd) in w10 tech preview (build 10125):



the transfer speed from the external ssd to computer is lower, i.e. avg. 198MB/s. (the normal speed in w8.1)

for common use, it should work.

I just checked the price, the difference is just about MYR40.00 max. For that difference i still suggest you get 900s.

Sometimes, i believe 'you get what you pay for'.

if there is nothing important on that ssd, no. there is not much that we have to do for house keeping anyway (other than regular backups for important data).

i guess older drives lacked of decent power protection. one of my oldest ssds lost all its data because of sudden power loss too hehe (it's not dead but it's like being secure erased) after reinitialized, everything is still working, the health is still good.

sure. mbr or gpt have no effects to ssd performance.

yeah mainly load time should be improved. there are others but it really depends on your setup and usage (e.g. file copy - ssd to ssd, not ssd to hdd or hdd to ssd - i.e. anything that is related directly to reads and writes).

oem ssds are actually similar to retail units with minor adjustments to suit oem orders. the main difference is warranty. this is the only sacrifice and risk that you need to make and take. if you're concerned about warranty, then don't go for it.

i have some sata oem drives. so far they work as good as retail units. they are very affordable so i made my own 'warranty' thing: get a few more as backups. the total costs are still lower than retail units.

tlc era is coming

yeah it depends on how you see things. tbh, my oldest ssd is an oem drive. (i couldn't afford spanking new retail units at that time, so my friend sold me a used oem at very low price ) it's been many years, and today it's one of my main storage ssds. there is no sign of health issues yet even if i use it to transfer very large files frequently.

the simplest way is to use disk management to produce similar outcome. the method uses built-in garbage collection (gc) and trim. all you need to do is to select the disk you wanna clean up, and delete everything (volume, partitions, etc.) in disk management. the drive will become unallocated fully. then leave it alone for 1 to 2 hours (some suggested leaving it overnight). if you're familiar with diskpart, the same can be done with 'clean'.

after the above, you can manually issuing trim to ssd again (e.g. optimize drive in w8.x) to make sure controller processes the command once more.

thanks for this article. it's a good read, bringing me back to those old code-reading days (supervise is still one of my favorite tools to be used in linux boxes lol!)

back to the topic, tl;dr; it's about ssds from samsung (the whole 8 series), certain crucial/micron, ocz, intel, etc. being blacklisted in linux's ata driver (along with other storage types and models), because of non-compliance to standards that involves disabling queued trim on them. (from that article, un-queued trim was used and caused issues too)

imo, it's really depends on usage. those are scenarios and workloads in heavy duty linux servers running 24/7. (those lines of codes can be translated into this, in terms of ssd: in mission critical systems, don't ever use consumer ssds, mainstream or enthusiast; and don't enable trim in linux if the ssd is listed). in reality, our computing loads will certainly not reach that level. i know the key point is still about trim in linux. how many of us have trim issues before that caused data corruption? i have crucial m500, and most of the samsung 8 series in that list. i have no issues so far. (maybe because they are running windows) of course, if you're running linux in your machine, i think it's better to avoid those blacklisted drives, or just disable trim if you insisted.

as for your question, yes, at least 330 is affected. (the answer is not obvious but it's in a link from that page, http://www.aerospike.com/docs/operations/p...ification.html)

i am not sure about this, but if it's using the similar method that handles hdd's secure erase, then it's not safe imo.

edit: buggy link fixed.

uh? you're doing secure erase, right? of course you can do that to a bootable drive. just boot from windows install media and do it.

imo unless the ssd is slower than usual, there is no need to do secure erase often. i just do every few months (up to a year) when i think it's time to reformat the drive and have a clean install/system restore.

That part referrred to a running system in which os in the boot drive is active. It simply means to do a secure erase on it you can either boot the computer with another tool (e.g. windows install media, or simply the tool created with ssd management software), or you put the boot drive to another computer via sata cable as non-booting drive.

no problem. good luck

you're confused with the ext4 fix with queued trim blacklist patches for libata. they are different. from libata-related patches (libata-blacklist-queued-trim-on-samsung-ssd-850-pro.patch, libata-update-crucial-micron-blacklist.patch) they just updated the blacklist to add 850 pro (and 850 pro only, not entire 8 series like upstream).

note that i didn't say that os other than linux have bug-free trim. i meant to say, literally, i haven't encountered data corruption issues with trim in windows based on usage as a user.

also note that it's not about file systems like ext4 (it's a different issue). the blacklist is in libata, the ata driver. (in debian 8.1's kernel 3.16.7-ctk11, actually debian just added 850 pro into the list, and updated crucial/micron's listing based on upstream) i suspect it cannot be fixed entirely via kernel patches, but it must involve manufacturers (e.g. to fix firmware issues). there are news that samsung was contacted about this. it was said crucial has done something to its firmware too.

well you can wait until there are proper fix. tbh, there were already a lot of user comments about nothing were affected significantly for common usage with linux. you can choose to use windows with any ssd; or, use linux with ssd not listed; or use linux with ssd listed, without trim.

liteon s900 256gb should be good enough for you but the price might be over 350. take a look at the ssd section in garage sales. you might find something worthy there.

haha that's why it's better to save more and get the largest possible.

hm there is not much you have to do. you can try look for firmware updates first and apply them. if it's w8.x, there is really nothing you have to do.

maybe your casing is older. new casings normally come with 2.5" caddies also.

i checked the laptop's specs, it's said that it supports sata 2280 m.2 ssd. (not pcie ssd) your choices should be among those sata-based m.2 bare drives, like plextor m6g. i'm not sure if it comes with a screw (plextor m5m msata unit does come with a screw)

mainstream sata ssds these days should run at similar speeds (m6g should be like m6s). for reliability, my preferences are plextor and crucial. (note that this doesn't mean other brands are relatively bad)

1) never used any sshd before. as for hdd delays, in power configurations just turn 'turn off hdd' option to never (0), and it should do the trick.

2) any mainstream sata3 ssds should be fine. they're cheaper also.

it's in control panel > power options > click 'change plan settings' in the current power profile > click 'change advanced power settings' > select had disks > select 'turn off hard disk after' > edit the value to 0

no problem. that's a part of basic ssd optimizations.

it's too old, and it's eol. transcend ssd370 is much better.

edit: for those who are interested in samsung sm951, there is a seller selling it in garage sales section, namely, https://forum.lowyat.net/topic/3593258
