Cheapest ever by a fair margin:

http://uk.camelcamelcamel.com/Crucial-CT1024M550SSD1-Internal-Solid-State/product/B00IRRDHW6

The M550 is Crucial's latest model that comes in 1tb. This is very likely the best 1tb option on the market.

Currently, Crucial's last-gen and slower 960GB M500 is the same price, which makes the M550 the no-brainer. Another option at 1tb is the newly released Samsung 850 Pro. It's faster and more durable than the M550, but it's supposed to be priced at between £500 and £700 - double the price.

The Samsung Evo 1tb is the only real contender. It uses a more cost-effective, but much less durable technology called TLC NAND - it should be cheaper than the M550, but it's currently the same price. The 840 Evo is quicker than the M550 at capacities lower than 256gb, but not at 1tb. They trade blows in benchmarks; they're the same speed. In addition, the M550 has built-in data protection on power loss. The M550 is undoubtedly the better option.

It's in stock in 3 days, and sold directly by Amazon with a 3 year warranty.

Edit: Now reduced to £299.99

Wasn't there already a 1TB SSD the other for sub-£300?

Yes there is one, but that's a different SSD. As a conscientious consumer, I would add that this one has far higher value for money. They're roughly the same speed, but this one has far better longevity, and data protection on power loss. Things that are worth far more than £6.

look up long term ssd test. 840 evo had over 100tb write without problems. that is decades of use for the average user. Samsung software is miles ahead as well.

I AM an average user, and I write 30gb of data to my SSD every day. It will take just under a decade to reach damaging levels, if we assume that all memory chips are the same (not true), which is a long time. But speed will deteriorate sooner with TLC, since performance decreases with wear on SSDs. And whether it takes a long time to deteriorate drives or not, the fact remains that TLC is less durable than MLC NAND. It is technically and practically inferior. According to the test you referenced, the MLC drives are at 500tb and rising with no problems. The Samsung Evo began finding bad blocks at 100tb. That's five times the endurance, and rising. Average consumer or not, I would never want to worry about drive endurance or performance decreasing over time. TLC doesn't grant you that security.

How about data protection on power loss? If your PC shuts down accidentally, it's going to be dangerous for the data you're using on your SSD. The M550 has data protection on power loss, and the Evo does not.

Samsung Magician does has some useful features, but nothing you couldn't get out of other software that works across all brands. I would pay £6 for data security and drive longevity over free, bundled, and unnecessary software any day.

In the interest of consumer awareness (and my own awareness), I'd like to know why you think that. I'm personally interested in upgrading my SSD, which is why I've read up on reviews, benchmarks, and the technology involved. Samsung do make best SSDs on the market. Their drives are made with exclusively in-house technology. But the 840 Evo is their "economical" drive, designed to be cost-effective. It's not the natural successor to the amazing 830 drive - the 840 Pro is. However, I'd be grateful if you could tell me what I'm missing.

It's an opinion having used both Samsung and Crucial products in the past...

I would agree that everything else being similar (sure not equal) I'd also get MLC not TLC; the whole point of TLC after all is cost - so the saving should be passed to the customer. I've no problem with the EVO and would get one myself once need an upgrade if the price is right.

Perhaps you'll never reach the limit with TLC, sure, but what would you gain to choose it at the same cost?

IMHO the added complexity/expense has eroded TLC's cost advantage and once MLC was reduced to 2Xnm the cost saving was gone. Sure the EVO is an engineering feat - but if the cost savings are not there - what's the point?

Perhaps one day TLC will be the only way - but we're not there yet...

Both my Crucial SSDs work and they do release firmware updates regularly; my Samsung SSDs also work.

I have several dozen 256 / 512GB M550 running in servers for about two months and it hasn't done that. It's compatible with all RAID cards, doesn't need no windows application to "boost" its scores and has a capacitor to cache data incase of power loss which EVOs do not have.which means high risk of data loss if you ever get a power cut on evos

I've been considering SSDs for some of my servers in the datacenter, got a couple of 12 cores doing nothing at moment. I think they're proved their reliability now. Any particular reason why it might be a bad idea in a virtualised xen environment, on hardware raid, used priomarily as a database server? Haven't had a HD failure for nearly 3 months, its a record, which means at least 2 are about to fail next week!

Actually that was a 100% false statement (it actually tends towards the maximum) but no-one picked up on it. I am disappointed with the lack of physics knowledge on HUKD. It's almost as bad as this guy being in government:

You won't be getting that. You'll get about 950GB. And they all have the same amount of capacity in nand, the difference in size is due to different levels of redundancy.

The difference is 20GB. I guess it's down to whether people want 2% more space or 2% better performance.

Yes, you'd expect HUKD to be filled with physics experts. I mean, why wouldn't it be? I hope this hasn't made you reconsider coming here to ask questions about quantum mechanics in the future.

I was wondering if your comment was some kind of super sarcasm.
If you had stated that entropy increases then it could have been a 'well duh' response, a nod to the likes of moores law etc that is, 'Of course they're going to devalue.'
But your statement was false which made me wonder if it was a sarcastic comment ie 'oh no I'm sure they're going to shoot up in price'. Sarcastic but quite convoluted.
Frankly I have no idea what you intended at this point, your statements are baffling and amusing.

Indeed, however you'll have to wait 8 months to a year to buy it at 250 or less.

If you calculate gigs per pound it becomes the most economical size of SSDs available at the time...

The failure rate on SSDs is actually much lower than normal HDDs but the thing is when they go they go quickly whereas HDDs degrade gracefully with a bit of warning. I would recommending changing the SSDs every 2 years within a server or at least implement rotation (i.e. in the raid replace some of the drives with new drives and keep the older ones to use for when some of the older ones fail).

It has been known for whole bunches of SSDs to fall at once because they had the same wear rate and were all put in at the same time, so if there is no fault then they can all reach end of life at the same time.

It's Samsung. That's good enough reason to get the EVO over this. Not saying these are bad, but if given the choice I'd go with the market leader. I've yet to have an ssd fail, touch wood, and my Samsung drives in general just seem more stable and reliable.

Same here, he actually had me doubting myself, and when another HUKDer commented about him 'getting it' I actually looked it up.
Yes you can engineer situations where it can decrease but it generally always increases.
I have absolutely no idea what the point of the initial comment was. But congrats to him for getting us thinking.

we have used the official enterprise SSDs from HP for 2 years in our VMware hosts, and also in our SAN as a tier0 shelf.
Just ensure all is in Raid1(on a host) and keep an eye on the SSD wear gauge on your host.

Also, you REALLY need to drop xenserver! best move is VMware, but HyperV is also OK these days. anything is better than xen...

HDDs can and do fail catastrophically, however expert data recovery can recover data sometimes, with SSDs they can fail and lose all your data with currently no way to recover it. However this is all IRRELEVANT as we all have backup plans don't we? If you don't then don't complain about HDD failure. HDD failure should always be just a nuisance not a catastrophe. Think now if your HDD or SSD failed would it be a nuisance or a catastrophe? If it's a catastrophe you need to right away make a solid backup plan.

I've seen businesses close down because they didn't backup. I recently had a customer who essentially was an idiot. He got his data cryptolocked and he was bitching like crazy about it. He said what am I supposed to do now? Go back to pen and paper and what do I tell the HMRC? I felt like saying tell them you didn't have a proper back up plan and it's your fault, because well it is your fault. Fortunately he had Dropbox and he could recover data that way, and he bitched about that too, having to go through each file and recover the previous version (as the existing synced version was cryptolocked).

If you're an idiot who hasn't made a backup plan. Then stop being an idiot and backup and do not moan about it when you lose all your data if you haven't backed up. I see it all the time, every week. So many businesses don't backup. You could be really really screwed if you don't so BACKUP!

Oh and a BACKUP is NOT :

RAID
An External Hard Drive.

How many people do I see who think a backup is moving data from one fallible medium to another. They say I have backed it up though, and I say no all you've done is move your data to an external drive. It might be termed a backup drive, but you didn't use it as such. The drive has failed you might have lost all your data. BACKUP!
