BL SSD discussion thread

devil

If you have an SSD, Welcome to the dark side!

If you don't have an SSD, it is highly recommended that you do join the dark side, you get lightning powers!

Dead serious here!

Joking aside, just a place to worship discuss SSDs... tongue

Re: BL SSD discussion thread

I kept it almost full (>90%) for a few months while also running some data processing applications that write a lot to disk. As in tens of GB/day. Apparently SSDs don't work well when almost full because the writes cannot be distributed evenly.

After a while it became really slow (20 MB/s seq write) but still worked for a few weeks, then one day it gave a few read errors, and a few minutes later after a reboot it was completely dead.

Since then I always leave about 10-20% of space non partitioned; I also run those applications on HDDs.

Edit: TRIM was enabled, but with the disk full it's useless.

I also have a new SSD now, although just a tiny one this time, which was quite cheap. I like the fact that SSDs are perfectly silent, and I also don't have to worry about moving the laptop while it's running.

How about you?

Re: BL SSD discussion thread

Good thing I get big SSDs, or at least, I only use them for boot if I can help it ( and 120GB's is generally enough for that ), although it will be interesting to see how my system does with >600GB's worth of SSD space, since I ordered a 512GB SSD the other day.

and my laptop has a 240GB, enough to run a windows VM with a VHD size of 50GBs and my music and a few other things lol

Probably even more ambitious, Going all SSD with my next server, since it seems like SSDs are only going to get cheaper and cheaper and cheaper.

Re: BL SSD discussion thread

Best computer investment I ever made.

Tom's Hardware says SanDisk Extreme Pro

StorageReview Leaderboard says Samsung SSD 850 Pro

AnandTech says both.

If your thinking of upgrading mobos, go for Z170 and Samsung 950 Pro.

M2 Adapter and the 950 Pro for older motherboards.

I'm thinking of a RAID with 3 850 Pros and an Intel 12 G/s adapter. Trying to justify spending $1000 on it.

Re: BL SSD discussion thread

at that price might as well just get a PCI SSD lol.

also iirc, samsungs have some TRIM issues, but from a little more research, it seems like it's been resolved, ( even the source says so too ).

Although my dad did get a 250GB 850 EVO, should be good for what he'll use it for ( nothing linux related, except for maybe inside a VM. )

Only RAID0 arrays using the "discard" option were hit by that and it was fixed quite a while ago wink
EDIT: Sorry, different bug ops

I have just bought a "250GB" Samsung EVO 850 (with a 5 year guarantee!) and it's fantastic smile

`hdparm -tT` gave ~530MiB/s compared to my "120GB" Kingston V300 @ ~265MiB/s

On the downside, it looks like my Kingston V300 is from the late production batch that had the cheap & crappy NANDs and controllers sad

I've put OpenBSD on it and filesystem (FFS) doesn't have a TRIM option but apparently this might not be as important as I thought:
http://comments.gmane.org/gmane.os.openbsd.misc/222829

If I notice any slowdown, I'll just backup then perform a factory reset on the drive and re-install.

Well, this is PCI SSD; A 12G/c PCI adapter with three drives in RAID 0. Blink and the OS is loaded. smile

Sure. At pennies per gigabyte, large storage drives are a bargain. At least for now.  smile

Re: BL SSD discussion thread

@Head_on_a_Stick

I've just remembered that I had not one, but two SSDs that died. The other one was a replacement for the first one, and got bricked in the first week of use when my laptop's battery ran out. Luckily I was able to return it to the store.

Most SSDs on the market cannot handle a sudden power loss, either corrupting the data or getting bricked. So overall I'm not so enthusiastic about them as you... losing data and money is not fun.

Re: BL SSD discussion thread

@o9000 -- which models were they?

AFAIUI, modern production SSDs may even outlast their spinning rust cousins.

See http://techreport.com/review/27909/the- … e-all-dead

EDIT: I've run my laptop down to zero battery a few times with no SSD problems.

I will have to watch that in future though, thanks for the advice.

Re: BL SSD discussion thread

The one that died due to wear was an Intel, I don't remember the model. One of the cheaper ones from 2012.

The one that died due to power loss was a Samsung 840.

Re: BL SSD discussion thread

I have a Samsung 850 Pro (256 GB). I need to rip open my case and make sure it is connected to a 6 Gig SATA port; I don't think it is. Even at that, my system boots in 4 seconds.

I have Arch Linux and openSUSE Linux installed on it, with their respective home directories. My big pure data (docs, photos, etc) and my swap partition are on a 6 Gig/sec 1 TB HDD.

Re: BL SSD discussion thread

I am running BL on a Crucial BX100 250GB SATA 6Gb/s 2.5" Internal SSD and love it. I still use mechanical drives for mass storage but want to migrate both of my laptops to SSD's in the future. Also, I should really consider getting an SSD for my external USB storage unit, given that I have already lost a couple of mechanical drives from shock. Given the amount of storage I have now, that is really pretty low priority.

Funny how you say that, I live in an area where I am prone to instant power outages, and my server running 24/7 whenever possible, the SSD is still in tact.

I actually worry more about the fairly recently acquired WD red 1TB than I do the SSD.

then it is an older crucial C300, reading about those, those seem to be trooper SSDs lol.

This one came on my laptop as one of those cache drives. It had some sort of softraid setup (two 10gb partitions) and I don't know how it worked, or if it even did something in a non windoze enviroment, so I decided to repartition it and use it for the boot and root partitions. It's running on 95%, and I think it slowed it down now.  I've had numerous power failures (329 apparently) since it's a laptop and I usually don't care about the red blinking light). luckily, it didn't bring me any problems. My data is backed up to a wd red everyday, so I don't care if it dies(and I hope it does soon so I can buy a real ssd free of consumer's guilt). ops

Re: BL SSD discussion thread

^ IMHO flash drives totally count as SSDs.  Really slow SSDs, but they're persistent storage and they're solid state.  I put my Android Jellybean seedbox with a micro SD card in the "all SSD" category as well.

My primary machine is my Thinkpad T410 with a 250GB Samsung 840 EVO (latest firmware applied).

It's running BL just fine.

@redcollective:  I can't speak for Samsung SSDs, but Crucial offers their firmware updates using a specialized Linux distro.  Reference the second page of the firmware guide for the M550 SSD here.  And...oh no, I need to update the firmware for my SSD!  yikes

@KrunchTime - Sounds like Crucial are more progressive than Samsung (mine), I've been googling - looks like I can use my Mac to make a bootable USB.
