So the search for a new drive continues:

Here is mystery candidate alpha:


Those are some sexy numbers, but there are so many to choose from. I'm praying for a firmware update for the m3p which will add more smart data because I really would like to run it.

[Computurd]

dont waste that m3p, i will kill you.

Notes:

a) New Endurance Testing system:
Intel i3-2120
Gigabyte Z77M-D3H motherboard.
8gig DDR3
using Intel RST driver 11.0

b) Vertex 4 has some problems with smart still:
* Seems to be counting hours fast.
* Sometimes doesn't respond with a correct remaining life value.

Maybe a later update will fix this buggyness ... but it shows the lack of polish on these controllers.

c) Intel's Matrix Raid 8.9 driver doesn't seem to support TRIM at all, and the vertex 4 was a LOT slower and buggier without TRIM. My advise would be to never use the vertex 4 on a system without trim.

Just a guess:
on Corsair Performance Pro 128GB same bug on Intel chipset (using Crystaldiskinfo 4.6.0. with Plextor PX-128M2P support): hours counting is faster (I remember something like 1 hour every 10 min)
On Amd chipset Power on count = Power on hours.

Firmware 1.08 changelog for Plextor PX-M2P:
http://www.plextor-digital.com/index...7/task,finish/

Date: 2011/11/17

Issue : SMART attribute (power on hours).
Cause : Due to EEPROM power_on_hours add one every 10 min, we should divide by six when response it.
Modify: [HostSata.c]

Not that severe ... seems to be counting a few extra hours a day.

rofl i really try to be friendly! just imo the M3P right now is about the hottest thing on the market. just my opinion, but i would hate to see one murdered, even for science

I believe the first RST supporting TRIM was 9.6. (will check)

Intel just hit MWI = 1 at 419.12TiB (host writes on drive)

Life may start getting intereting from here on ... maybe

I'm not sure if I dare to do a retention test on the m4 when it passes 800 TiB based on the last time I was here.

There are two things you should know - one, its not an M3P. And two, I can totally take you in a fight.

vt64
387,230 GiB
378.15 TiB

830 256GB
814,296 GiB
795.22 TiB

The 830 is at MWI 2 with 3550 wear leveling count.

The 830 had 75 hours and 215GB host writes on it at the start of testing. After 810 hours, its at 814GiB. 290.68MB/s over the last 400 hours or so. Not too shabby.

[Christopher]

you know, my laptop has the ich8m southbridge, and it supports AHCI, but no Intel drivers past Matrix 8. And I'm pretty sure it supports TRIM.

[Ao1]

21 April 2007 - T13e07154r6/ Data Set Management Proposal ATA8-ACS2/ Initial Draft
22 October 2009 – Windows 7 released
26 October 2009 - Intel release f/w update to enable TRIM on their X25M G2 drives
19 March 2010 – Intel’s first TRIM enabled driver - RST 9.6.0.1014

Seems like a life time ago, but its only couple of years.

[thegoatman]

So, from this data, what is the most enduring drive available in the 200-300 USD range?

[Computurd]

oh lord Your feisty, and I like that but then again, so was my last cellmate, and we all know how that ended......

[canthearu]

Are you actually going to make use of that endurance? If not, then endurance shouldn't be your primary thought.

[thegoatman]

I am about to make a new build within two months, which will likely be the last one I can afford for at least 4 years, probably more. So I may very well.

Other considerations are price, capacity and bugginess.

Typical yearly writes to an SSD for desktop loads are less then 10 TiB a year.

Virtually any SSD can handle that for a few years .... even the old barefoot drives .... the real risk is with the controller or NAND outright failing, or a power surge, or some other kind of instadeath failure.

For $300, you are probably best off with a crucial M4 256gig. Not a particularly special drive by any means, but cheap, generally reliable and well polished. Won't have the highest endurance rating ever, but will still give you a good 600TiB of service before the Media is officially worn out ... and possibly another 1PiB or more afterwards. Not that you would ever reach that point.

[thegoatman]

right. What about the samsung one? $30 more and it looks to be 30% faster, if I understand the specs properly.

As far as my longevity concerns above go: The way everything I have read made it sound, I was thinking I might get, oh, MAYBE 6 years out of one. I guess that's incorreect.

If you budget stretches enough, the Samsung 830 is a great choice. Fast and reliable.

No-one really knows how long you will get out of a drive, that is pretty random .... what I do know is that you are not going to wear it out doing any normal sort of things with your computer any time soon.
