Might be worth holding off for Amazon Prime Day on 12th July as SSD's are bound to feature (?)

You can get a 500GB Sandisk Ultra II for £80, which means that for £160 you could get two and set up a speedy 1TB RAID-0 array.

What makes you think this is worth the extra £55?

I don't think this is a "cold" deal, but it certainly should be ~£200 as a "normal" price by now.

Not a decent price imo

Not losing all of your data when the RAID-0 array fails?

Two drives in RAID-0 are twice as likely to fail compared to a single drive. Why bother with RAID-0 at all, especially since most people don't need double the sequential read/write speeds?

Right.... those high SSD drive failure rates are common knowledge, and definitely more prone to failure than mechanical hard disks spinning their platters thousands of times every second.

Given that the prevalent reliability factor in SSDs is block data loss, and a RAID-0 array of two striped 500GB drives would have the same number of blocks as a single 1TB drive, surely you would agree that the block reliability would be identical between the two?

Having said that, for mission-critical data-storage, you wouldn't be using any consumer data solutions, anyway - you'd be buying enterprise-level storage - so, again, your comment is equally relevant to the 850 EVO as it is to the Ultra II, and therefore not a counter-point.

But, imagining for a second that everything you said was both relevant and technically accurate, then I'll just point out that the 1TB Ultra II has been £150 before - so then the question becomes, what makes the 1TB 850 EVO worth the extra £65? :man:

you should be a politician....quoted my question and never actually answered it
as per my original reply to Linhang90 "and you can find it cheaper where???"

also...a pair of 500Gb drives in a striped array aren't going to be a a lot of use in a laptop with a single drive bay..

Relevance, m'lud? At the risk of stating the blindingly, overwhelmingly obvious, the cheapest price for any given product today doesn't automatically make it a good deal. Otherwise every single product in every single category available on the market would have to be posted at HUKD every day for it happening to be the cheapest price of that particular day, from wherever it happens to be.

That's what aggregate search engines are for, not deal sites.

Funnily enough, you also quoted my question and never actually answered it! You....should be....a....politician.


At the risk of repeating myself... "then I'll just point out that the 1TB Ultra II has been £150 before - so then the question becomes, what makes the 1TB 850 EVO worth the extra £65? :man:"

You are missing the point. Even though SSDs tend to be more reliable than HDDs, that doesn't change the fact that RAID 0 decreases the reliability.

Why even bother with RAID-0 if you don't need it? People who do need very high sequential read/writes in a desktop PC or laptop would be better off with an NMVe PCIe SSD anyway.

I'm going to try and keep this brief, because it's clear you don't understand the difference between a mechanical hard disk and an SSD, but the basic point is that SSDs tend not to suffer the total catastrophic failure that HDDs do. Your second link revolves (no pun intended) entirely around HDD failure and is simply not applicable, and your first link also refers to the failure of a drive rather than the failure of a single block.

SSDs are not HDDs.

Do you need a Wikipedia link to explain the difference? I'm sure you can Google some fairly basic interpretations to help you understand what's happening. Try "differences between SSD and HDD" for a start.

Why even bother with RAID-0 if you don't need it? An excellent question, but I'm confused as to why you're directing it at me. I was simply pointing out a cheaper, high-performance option, not a demand that everyone should start using RAID-0 arrays. I do apologise if this was not completely, utterly, overwhelmingly clear. But looking back... well, it kinda was. Hence the use of the would "could" rather than "should". :innocent:

I can answer that question for you as I have an 850 Evo and why its worth the extra.

The Ultra II, actually all of SanDisk SSD's are known to be the low end of SSD's, they have slower write speeds compared to the Samsung or even Kingston SSD's.

The Samsung Evo 850 uses 3D NAND, which has better performance and reliability compared to the SanDisk Ultra II. On that note, you should be comparing the SanDisk Ultra II against the Samsung Evo 840 NOT the Evo 850 as the Ultra II and Evo 840 are from previous generation of SSD's technology. This Evo 850 is from the the current of SSD's technology.

Not that is matters to many people but the SanDisk Ultra II offers 3 years manufactures warranty while the Samsung Evo 850 offers 5 years warranty.

So is the 850 Evo worth the extra money? Yes, if you want newer, more better SSD technology, longer warranty period and upgrading from older SSD's.

If you are upgrading from spinning disk HDD then go for the Ultra II as obviously it will be quicker than any spinning disk HDD. But its cheaper because the Ultra II is old tech and stock many retailers are trying to shift. Ultra II is cheap for a reason. You get what you pay for.

Your technical reasoning above is sound, faultless in fact but you're impractical.

If someone for example wants to put the disk in a laptop or a single bay NAS device your proposed solution is worthless.

The whole point of HUKD is to find the best price for the product required, if that product is a single 1TB SSD, then 2x 500GB's isn't good enough. If it's a Samsung SSD not Sandisk, so be it.

So your reasoning is i'm afraid, cold.

I offered two alternatives, actually - RAIDing two 500GB Ultra IIs for £160, or a single 1TB Ultra II at £150. The latter solution - the one you didn't quote, for the obvious reason - works perfectly for a laptop or a single bay NAS device, right? Am I missing something? So your literacy is cold, I'm afraid. :wink:

It's also worth pointing out that I was just offering alternatives off the top of my head - I'm sure there are many other possibilities that work out faster and cheaper than this almost-deal. They were merely suggestions to try to help other HUKD users.

So when I said "At the risk of stating the blindingly, overwhelmingly obvious, the cheapest price for any given product today doesn't automatically make it a good deal. Otherwise every single product in every single category available on the market would have to be posted at HUKD every day for it happening to be the cheapest price of that particular day, from wherever it happens to be..." - you're saying that, yes, we should be including the cheapest price for every single product of every single brand in every single category every single day? :confused:

Well... I can't see why you think that, but wouldn't life be boring if everyone had the same opinion about everything? :smiley:

Despite three other people commenting, I appreciate you being the first person to chime in with why the 850 Pro is a "more better" (:wink:) drive than the Ultra II - and you're absolutely right that it is. I'd certainly pay an extra £30-40 to get an 850 EVO over the Ultra II. Yeah... £190. That'd be about "write" for the 1TB 850 Pro today (sorry!).

So after all the waffling basically If you are after THIS particular drive then this is the best price currently available by at least around £25-£30 (If only we had time machines to pop back to November and get one for £185)

Yes lower spec drives are available for less money (no really?!?!)

Seems to meet the criteria of a good deal to me. Voted hot

1. The sequential write speed of the Evo is about 50% higher which is clearly significant for some workloads.
2. It supports encryption.
3. Warranty is 67% longer.
4. Much lower slumber power consumption.

For many people those things will be irrelevant and not noticeable but it clearly is a better drive.
Is it worth the extra money? That's purely subjective. :wink:

Amazon prices are funny:
Jul 10, 2016 01:17 AM £210.89
Jul 09, 2016 03:34 PM £215.83
Jul 08, 2016 04:49 AM £239.99
Jul 07, 2016 09:53 AM £221.32
Jul 06, 2016 03:01 PM £252.28

Now showing as £195.....

through a random Marketplace seller with only 14 sales

Amazon direct price is now down to £210.89 however

Will be under £200 for Prime Day I am guessing

Buy today, don't open, send back if cheaper on Tuesday

Thousands of times every second?
Even a 15,000 RPM drive only spins 250 times every second, and only highend SCSI drives spin at 15k... Your typical consumer 7200 rpm drive is less than half that.

That still doesn't make it a decent price by you saying that. Just because you can't find it cheaper elsewhere... they shouldn't cost this much nowadays.

betting sites should start putting bets on prices of Storage .. i'm betting for 2TB to be £200 this year end.:man:

I completely agree. Just because its the cheapest aty the moment doesn't make it a hot deal. A little patience (Prime Day - not the wait for the eventual deflation of consumer goods) and genuinely hot deals will present themselves.

A 2TB SSD for £480 would be cheaper than anything I can see right now, but per GB it's aweful expensive.
I could sell my belly button fluff balls for £5 per kilo. You won't find a better deal than that, but there is nothing hot about my belly.

expired, price now £239.99

Although this is more expensive than the cheapest budget drives (Ultra II for example) this is a combination of the best value for money, warranty, speed, and reliability.

Is it worth the extra 50-65 quid? That's a valid question, but please don't try to pretend the Ultra II and the 850 evo are in the same ballpark in terms of performance.

voted hot..

Maybe there're cheaper SSDs out there but by far 850 EVO is the best of all TLC SSDs and its performance is very close to many MLC SSDs.. there're very few other SSDs which can challenge 850 EVO at its price range. Yes, the price tag does carry premium but if you need a better performing TLC drive I think this is well worth the money.

I do agree Amazon Prime subscribers should probably wait for the prime day, this was £189 on last Black Friday so there're very good chances a similar deal may pop up again.

Yes this is a brilliant drive Cant fault it. But that doesn't mean this is a good deal,a good deal should mean good product and good price and just because you can't find it cheaper on amazon doesnt mean its a good price :smiley:

A good deal is a good product at a good price, so why isn't the original price good? No one on this thread criticising the deal seems to be able to post the 850 EVO at any price to prove their point.

The fact that I'm even in this thread is because to me it looked a good price, I've looked at other 1TB drives, but a drive his size isn't going to be replaced that often, so the 5 year warranty may actually be important. As it's to fit in a high end laptop doing pretty intensive work, it's quite likely the performance would be a benefit, but there's 0% chance I could build any raid array in this device so a single fast and reliable drive is what I require.

Now showing as £239.99

Going by the Whatsapp message I just got from HUKD, there will be a very very interesting price on a crucial mx300 750gb ssd tomorrow on the Amazon Prime sale (not far off half the price of this one!)

I'd struggle to fit Windows 2000 and office 2003 on 750mb though.

Well spotted. Updated :smiley:

According to the HUKD blurb its best deals, so a certain product at the cheapest available price is exactly that, the best deal.

Good deal is something different altogether and a matter of opinion.

price has now dropped today from £239.99 to £208.93 (Amazon direct)

price all over the place !

I'm betting this will be sub-£200 for Prime Day tomorrow

£208.07

​Sandisk uktra II are amazing drives, got two 120gb in raid0. That thing is fast! 500gb for 80 is a steal!

There are obvious exceptions like OCZ SSDs before Toshiba bought the company and SSDs with firmware bugs (Crucial M4, Intel SSD 320 etc.).

RAID-0 is RAID-0 whether we're talking about HDDs or SSDs so of course it is applicable. The way the data is striped across the disks is the same because each drive only stores half of your data.

That's because when one drive fails in a RAID 0 array you have lost ALL of your data.

disappointed this hasn't featured today. Maybe they're holding out for a 9pm or 10pm special lol

Back to £240~

Agreed. However when a 1TB SSD pops, it's junk, while two 500GB SSDs when one pops, still leaves you one usable 500GB SSD.

I don't find RAID SSDs used for Windows much faster, but am using RAID SSDs as targets for some of my workflows as the extra write speed helps.

4TB SSD anyone?

expire please mods. thanks :smiley:

price has dropped from ~£239 down to £214.48

interesting a Marketplace seller has one for under £200 (£198.96) so hopefully Amazon will push it's price down under £200 mark

For the 1tb SAMSUNG 850 EVO SSD Currys price £239.99
Maplin price £249.99

Argos price... £339.99 wtf lol

I'm waiting for £200. I imagine Amazon price will drop down again soon. Seems to change daily.
