SSD TRIM Command on RAID 0 Possible - With A Few Riders

[btarunr]

Intel made it possible for SSDs to utilize the TRIM command feature when striped in RAID 0, provided a few meaty requirements are met. The TRIM command feature works to minimize write performance degradation on SSDs, but thus far it has been impossible to enable the feature on any other host controller mode than standalone AHCI, due to the manner in which the feature works at a physical level.

According to a report, TRIM over RAID 0 will be made possible with Windows 8 operating system, provided the system is running an Intel 7-series chipset (such as Z77 Express), has RAID BIOS (Option ROM) version 11.5 or higher, and Rapid Storage Technology (RST) device driver version 11.5 or higher. While obtaining the required Windows and driver versions is relatively easy, the RAID Option ROM version is in the hands of motherboard manufacturers, who have to release motherboard BIOS updates that include the required RAID Option ROM updates.

so M$ payed intel for the TRIM only to work on win 8 Great

[Svarog]

It works on Windows 7 aswell.

It works with AMD SB600 and newer southbridges on Windows 7, as well. I did tests with various disk recovery applications with very powerful detection of data and TRIM indeed works.

I'm waiting the day when SSD's won't have stupid degradation nonsense on write commands and that TRIM will remain a thing of the past. This is really one of the biggest downsides of NAND Flash memory... Something we never had to deal on standard HDD's despite their fragmentation over time.

[seronx]

If you received a SSD today you could write 10 to 100 gibibytes(GiB) of data per day for 8 to 9 years. If it fails within that time frame it isn't the NAND Flash.

The degradation of HDDs really only make them last 5 to 8 years if you are lucky. SSDs in perfect shape will always outlast HDDs in perfect shape.

About time. I dont know why it took so long, more people will use RAID now and they'll sell more drives.

Sure. On paper. In reality, controller will one day without any symptoms decide to completely die. Something i haven't yet witnessed on any HDD. They always started to have some sort of minor problems or release strange sounds. With SMART monitoring like Crystal Disk Info it's almost impossible for it to die on you by surprise. SSD's on the other hand can, despite the hyped durability and crazy high MTBF ratings...

The controller will always tell you when it is going to die.(This can actually be remedied by fully erasing the drive and reinstalling everything if you have everything enabled the controller won't cause any problems)

Stuttering
BSODs
Random Chkdisks
Drive gets detected but doesn't load something
You try to read you get a glitch

The sudden deaths imply that the controller got overheated this is a problem with the manufacturer not the NAND or Controller. <-- this usually always happens within RMA time.
Another case of sudden death is a bad power supply or bad cables connecting to the power supply. <--- Again, always within RMA time.

i had stuttering and BSOD's for all of three days before my SSD died. its impossible to know what caused them, until it died completely. all data was lost off the drive.

[mussadek]

I think most ppl are mistaken what SSD meant for, if your looking for long term backup or saving your data , then u have to use HDD or Media storage, SSD are good for fast accessing and serving , Ahh and you can buffer your data on it too

Don't forget all the BSOD problems, whole disk shrinking into 3MB or completely disappearing, and how heavily SSD's rely on it's firmware...

Despite all that it is the future.

Mechanical HD are just to slow for me anymore. Can't stand em. If my SSD died tomorrow guess what......I have a back up. Also I store all my documents on another drive which gets backed up nightly. Only thing on my SSD is programs. Things I can reinstall at any time. Hell its still under warranty. If it dies tomorrow Ill be down for as long as it takes me to install windows on another drive while I send the SSD into RMA.

SSD's are perfectly safe if you take the right precautions. Precautions you should take with ANY DRIVE. Mechanical or not.

The Intel X25-E SLC SSD in TPU's database server just died one day. Without any warning or reboot or power off. Just *poof* gone.
The replacement drive has been working without issues since, but I am prepared for it to fail at any time. We are too poor for RAID 1 (50$ per month for a 2nd drive), got a real-time backup working though

[Steevo]

Too poor for RAID? Ads man ads........

Sell some of us schmucks some of your goodies.

[W1zzard]

50$ per month to protect against drive failure that happens like once every few years doesn't look cost effective to me. Especially since we can recover in half a day worst-case, half an hour best case.

[Steevo]

Ahh, true.

How much work did it do(in GiB) and how long was it active(24/7? 3 months 6 months?).

[Arctucas]

Now Intel needs to allow it on older chipsets (58,67,68).

[eidairaman1]

They wont less they get bitched at enough, then again there is like a .0000000000000000000000000000000000000000000000000 01% chance they will make it possible.

You have to realize this is intel the greediest semiconductor company around

10 on there that I knew were, just forgot. About another 7 I didn't expect (panasonic). The rest I have never heard of. Well glad to know there is so many of them.

[n-ster]

I hope I'm not the only one who backs up his,SSD weekly on his HDDs... I have 4tb of HDDs, sacraficing 200gb aint gunna kill anyone. If you can afford an ssd, you usually can afford to back it up to your HDD

I take this as a joke. Or you accidentally swapped HDD for SSD. Really now, I have HDD running perfectly from '98, and haven't got 1 problem with them, made by WD, Seagate, Maxtor, Samsung or Hitachi. On the other hand I had 2 SSDs that died on me, first after 3 months, the later, after 1 year. So...
