Momentus® XT Solid State Hybrid Drives

[AtW]

I've been running two SSD Intel 150Gb drives for about six months now. They host my Sql server TempDb and a couple of the most active databases for plan B, so far they have had around 20Tb in writes to each of them and show zero on the media wear out stats in the management software they come with.

20 TB is a lot of writes, especially for older disks that did not have that smart wear levelling algorithms, you must be using SLC SSDs, in which case you might still be ok , but for MLC 20 TB written isn't small amount.

SSDs are ideal for reading a lot, but writing rarely.

t, but writing rarely.

Tosh. You make it sound like the transistors are being switched over with an arc welder. Calm down. Back home that's what we call an overcooked ham.

It's clear to me that you have not got a clue when it comes to flash based products.

Not that I'd expect someone who prefers Macs to have good understanding of hardware.


Writing 20 TB on SSD can easily kill it - it all depends how you write that data because SSDs have got erase/write cycle, so if you write few bytes then in actuality you cause 4kb worth of efforts. MLCs have not got that many cycles, in fact even if you write sequentially SSDs will slow down pretty quick - I'd love to tell you more about SKA and SSDs, but that's confidential information.

What's that got to do with hardware performance? If you drive your car like an idiot it's going to fail a lot sooner -

It's clear to me that you have not got a clue, full stop. < the little dot down there in case you were wondering.

What's that got to do with hardware performance?

Everything - SSDs slow down big time after enough written to them, recent models better than old ones but still slowdown is very noticeable.

You know **** all about hardware, and especially SSDs that don't follow normal patterns (in both good and bad ways), so stick to your usual "I got more GBP because EUR is so strong threads", I don't know what they are paying you more than minimum wage, but clearly that can't possibly be anything at all related to computer hardware in general and SSDs in particular.

Fight!!

What lithography machines were your SSDs were made with, cheap skate.

Thermal shock is the only thing that's going to cause an SSD to fail big time but electronic switching within the technical specifications? Not once not never - like was said before, drive like a idiot expect to have a failure soon, otherwise happy times, unless there was an inherent quality problem at manufacture.

How do you OU grads get into industry?

L-i-t-h-o-g-r-a-p-h-y - that's a BIG word for a Mac user. We have got latest SSDs - 34nm.

It's not switching idiot, it's erasing and programming new block - flash NAND was never designed for so many writes, it was meant to be mainly as primarily read medium, more to the point the way they are designed a write of few bytes will force erase/write cycle of whole 4k block. SLCs were pretty good (if you don't know what it means in context of SSDs then you should **** *** **** up right now and go play with your ipad), but cheaper MLCs can have write endurance of anything from 1000 to 10000 cycles.

As I said STFU and stick to your "I am richer than you because I am paid in euros" threads, before you even open your mouth to talk about hardware first own PC for 20+ years, fix all sort of problems, program hardware on a low level (like our own Spod, bless his doggy soul) and only then open your yapper to comment on things you don't have any clue about.

[Cliphead]

AtW's quite correct. Enjoy your new drive but make regular backups

I'm afraid it is switching. From one state to another. You don't know this?

No need to get so upset. The device retains it's 1 or 0 by switching from one state to another, nothing more complicated than that. Unless it's multiple states with which you are referring.

This can occur numerous times.

But as I said before, if the driver operates the product like an idiot it's going to fail, the hardware could operate indefinitely.

I understand now why I'm paid the big bucks...
