Samsung Releases First 2TB Consumer SSD For Laptops
Lucas123 writes: Samsung has released what it is calling the world's first 2.5-in consumer-grade, multi-terabyte SSD, and it's issuing the new drive a 10-year warranty. With up to 2TB of capacity, the new 850 Pro and 850 EVO SSDs double the maximum capacity of their predecessors. As with the previous 840 Pro and EVO models, Samsung used its 3D V-NAND technology, which stacks 32 layers of NAND atop one another in a microscopic skyscraper. Additionally, the drives take advantage of multi-level cell (MLC) and triple-level cell (TLC) (2- and 3-bit per cell) technology for even greater density. The 850 Pro, Samsung said, can manage up to 550MBps sequential read and 520MBps sequential write rates and up to 100,000 random I/Os per second (IOPS). The 850 EVO SSD has slightly lower performance with 540MBps and 520MBps sequential read/write rates and up to 90,000 random IOPS. The SSDs will range in capacity from 120GB to 2TB and in price from $99 to $999.
Finally we have a reasonably sized SSD... now it's just got to come down in price 80-90%
I suppose there are a few 5 pound laptops out there for power users that still use the 2.5" form factor, but they're disappearing rapidly. Things are moving fast in the SSD storage area and many are moving to the M.2 format. Though I suppose any increase in density is good as it means higher cap small format drives and cheaper options*.
*so that Microsoft and Apple can increase their profit margins on storage. The great thing about impossible to open PCs is that they can charge whatever the fuck they want for storage no matter how cheap it gets.
Is it just my observation, or are there way too many stupid people in the world?
the good news is that fantastic advances in memory construction are coming to SSDs. the bad news is all SSDs and HDDs are relying on security by obscurity and at some point everyone's storage devices will be permanently infected with malware that gives away their personal information.
Anons need not reply. Questions end with a question mark.
Can you imagine how long that thing's gonna take to rewind, let alone defrag? I think I'll pass.
Do the hard drives come with firmware that turn off Windows update?
The price-per-gig on the EVO model comes out to around $0.40/GB, which is where SSD prices have more or less been stalled for a few years now. So that's not so great. We really ought to be seeing some price reductions from 3D NAND.
On the other hand, $800 is roughly what I paid for my first SSD, an 80GB Intel G1. Today, for the same price, you can get 2000GB.
We've been using Samsung drives in "non production" status servers, embedded servers, etc. and have had a terrible time of it. The first drives we bought a few years ago (840 Pro) were good, but we've seen Samsung SSDs run entirely through their write capacity (as reported by SMART) and then go dead when not even mounted! Turns out we aren't the only ones to get bit by buggy Samsung drives.
It also turns out that Samsung drives are even blacklisted in the Linux Kernel
I welcome Samsung's excellent cost/size value proposition! I just wish their drives were solid enough for our actual use.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
It's the first time that max SSD capacity is greater than HD in a given size.
Yes, I know there's a 2.5" 2TB HDD out there. But it's a 12mm height, and so cannot be used in any laptop that I know of, including my older thicker MacBook, which takes a 9.5mm height drive.
This Samsung is a 7mm height, and thus will fit in any laptop that takes a 2.5" drive of any kind.
Who needs local storage? We use the cloud now.
This is 2015. I go to Costco and see 3 TB for 66 dollars.
We've been putting a few Samsung 850 SSDs in servers since last September. About a tenth have quit already. They wear-out fast. SMART info for the last one I installed:
# smartctl -a sda
Device Model: Samsung SSD 850 EVO mSATA 120GB
Serial Number: S249NWA[deleted]
9 Power_On_Hours 0x0032 099 099 000 Old_age Always - 802
177 Wear_Leveling_Count 0x0013 099 099 000 Pre-fail Always - 8
241 Total_LBAs_Written 0x0032 099 099 000 Old_age Always - 1848781952
It's 8% dead already after just 33 days! We've had to give-up on SSDs for now. They just wear-out too quickly.
This is great news! i love these drives and with Samsung rapid mode I get 5-6GB/sec on my current 840's and 850's.
Awesome information! Thank you!
TRIM is broken in lots of SSDs, and was in most of them until very recently. There's a reason it's disabled by default.
This doesn't absolve Samsung, but calling them out specifically is a bit disingenuous when that's just the norm.
With DDR4 and the huge amounts of ram available to modern desktop pcs, I would think the ramdrive would be gaining in popularity. I guess though, if you've got sensitive data a ramdrive is a bad move.
I had a Samsung SSD crap out on me after less than six months in service, and that was just on a normal general-purpose desktop PC that was mostly just running Firefox, OpenOffice, and a few other light-to-medium-duty applications. (I.E. no gaming, no SQL database servers, nothing that would be constantly hammering the drive with large data requests and constant rewrites of information, or at least I shouldn't have thought so.)
I like the speed, but IMO, when it comes to reliability, SSDs are just not ready for prime-time.
More specifically, TRIM is not broken in those drives but it is designed to work against the behavior of Windows mass storage subsystem. Linux can issue unexpected command patterns which can make the drive enter weird states and get confused. It's the same thing that happens with ACPI: in practice no manufacturer writes against the official spec but against the Windows spec.
The mess should be fixed really. Either the SSD makers should get their shit together (the proper solution), or the Linux kernel should be modified to be more compatible (the practical solution). Currently there is just a list of devices with blacklisted TRIM in the kernel and that list keeps growing.
The 850 Pro, Samsung said, can manage up to 550MBps sequential read and 520MBps sequential write rates and up to 100,000 random I/Os per second (IOPS).
There's nothing special in bothering to even mention the speeds of current consumer drives. They all saturate the SATA 6Gb/s bus, and that's that.
This summary is well written. It is:
As a former professional technical writer, I am always on the look-out for good explanatory writing. I wanted to call it out here, especially since often we just complain when the summary's bad. When something's good, we're often silent. I suppose that's partly because when things are working, like the utility company, they don't attract attention and we just take them for granted. But writing like this is no accident.
So the kernel maintainers are supposed to just assume that since the equipment doesn't comply with the published spec, it will comply with some undocumented specification instead? The drives are blacklisted because they report features that are not actually implemented
This type of situation isn't exactly unique, I recall some video adapters reporting features allowing for "aero" capability around the release of Windows Vista, however the feature was disabled for those units due to them not implementing the features properly.
"My Documents"/prog/nethack on my laptop is about 7MB, including a bunch of bones files and a saved game or two...
But yes, bigger hard drives can be useful. My last laptop refresh at work went from a 300GB rotating hard disk to a 256GB SSD, and I had to move my music and Linux ISOs to an external drive. (Eventually I added a 128GB SDXC card, but the news keeps saying that the latest iTunes has serious bugs, so I haven't reinstalled it yet.)

Someone posts actual experience with real data, and the Samsung fanbois bash them for it and mark them as a troll. This site is dead. It used to be a tech site. Now, it's just a bunch of angry children trying to protect the corporations they worship. Corporations have replaced god in this new Internet age. Now people want us to die for telling the truth about crappy products. That is the way of their kind.
Again, Samsung SSDs do not last long enough in any nontrivial application. The ones we have at work typically die within five months. They have a lower TCO than the Dell enterprise drives we were using, that were very high quality and typically lasted over a year, so we still buy the Samsung disposable drive.
My wife's Lenovo laptop power connection fried recently, and we got to discover the joys of different SSD formats. The first generation X1 Carbon had a Sandisk 20+6 format, and I think the second was M.2 and the third some mSATA format, but I may have the latter two backwards. After looking around online for a while, I found a $25 adapter board from China that lets you plug in the 20+6 drive so you can read it on a "standard" SATA connector, so we were able to back up the data before sending it in for (Yay! Just under the deadline!) warranty repair.
(We even got lucky, either they didn't need to replace the motherboard after all, or they did replace it with the same kind and the old SSD worked, or they replaced both and really transferred everything; in any case there's still an operating system and her data. I really wish Apple would lease their magnetic-connector power cord patent cheaply enough that everybody would use it, since it prevents all kinds of damage.)

Then how is Apple having such good luck with them? Granted, Macs aren't generally used as high-transaction-count Servers; but people who do media creation/editing can sure churn through some R/W cycles in a hurry.
It has an SSD daughter card on the motherboard. (As I ranted above, three different generations of them had three different interface formats, but to be fair, the market was changing rapidly.) There's no room for a 2.5" drive. There are probably other ultra-thin notebooks with that limitation as well.

Why in God's name are you using SSDs in a server (production or not) without using hardware RAID? And none of that fakey-RAID that Linux sees right through either, I might add. From what I can see it's a problem between Linux trying to manage TRIM and the drive getting confused. Cut out the middleman, RAID them and underprovision a bit to give the drives more life, and then let Linux only see the storage presented by the RAID card and let the card itself handle communication with the drives.
This opens up a whole new door for VSAN All Flash, and workstation storage. SATA is crap, it was made for magnetic disks, not ultra low-latency Flash. New generations of storage for the consumer/enterprise must become reverse compatible with SATA, but have NVME and SAS controllers. Any SATA device is not a "Ferrari" its a ford escort with a Ferrari body kit. They have practically no Queue Depth, constantly abort all commands, and many more downsides. That fact we are seeing new devices for SATA, and not "legacy SATA compatible" is a sign of the times. Times where the "think they know shit consumer" cause the release of inferior products, cause they are the majority. Much like video gamers be content with non-innovative regurgitated games. All in all its a horribly missed opportunity for Samsung, and companies like Intel will pick up this dropped ball. IMHO
Maybe it is just me, but if I have to spec a SSD by brand, it will be Intel. $2200 gets me a 1.7 TB Intel enterprise tier SSD (DC S3710.) It isn't cheap by any means... but you get what you pay for, and Intel has a very good reputation for reliability.
Since TRIM is a standardized command, SSD vendors either need to support it, or like is done with the format command on IDE drives... do nothing, return a success value.
It is better to do nothing than to do it broken, and TRIM isn't exactly a new technology... it has been around for quite a few years now.
Doesn't matter whether they use security-by-obscurity or real hardware-driven or OS-driven encryption. The malware's running on top of the OS, which already has access to all the data on the drive (unless you're doing something fancy with multiple user logins, each of whom has differently-encrypted home directories, but even then, the malware can attack whoever's logged in right now.)
Drive encryption mainly helps you against stolen hardware, and not usually very much, because that would require an inconvenient user interface.

TLC is a kind of MLC. "Multi" means "more than one". Multi does not mean "two and just two".
I am surprised it has taken this long to get to 2TB. Perhaps the price on 1TB will drop a little now, as they are no longer considered a premium drive.
[Personally, I have 750GB of data. When replacing drives, I've always bought twice as much storage as I have had data.
Once you do anything with video, space goes quick, I also have lots of photos, graphic projects, CAD and design projects.]

apparently you've learned nothing at all, modern computers are steeped in layers and layers of "doing it wrong" for the sake of compatibility
There could be some kind of ata_mimic=winnt61 kernel argument. In this case it would enable a feature set that matches Windows 7. For example, some drives incorrectly claim to support queued TRIM when they actually don't, and this makes the drives explode under Linux. Under Windows 7 the drive happens to work, because the operating system does not even poll the drive for queued TRIM support, because it is not part of the Windows 7 platform.
Would like to have seen a SAS version.
A pox on web designers who feel that window.innerWidth == screen.availWidth
...using these con/pro-sumer drives and not high-dollar SLC enterprise drives?
I've been long tempted to and more so with the generally positive results from the SSD write-them-to-death-athon that wrote to SSDs until they expired.
I know it's "not advised", risky, etc, but I'm thinking that maybe the drives are more reliable than we think and between backups and maybe a double parity RAID scheme or hot spare the risk is dialed down, or at least worth taking on a what-if basis.
For my own home/lab VMware cluster I'd sure like more disk performance than spinning rust gives me.
First off, the problem is Linux is somehow triggering a bug in the TRIM implementation on Samsung SSDs.
We know Windows doesn't do it, as Windows users are probably the biggest consumer of Samsung SSDs and there isn't a mass loss of data problem from Windows users. (And from querying Windows 7 via the command line, Windows does use TRIM).
OS X may be using TRIM or not (depends on whether you're talking Apple-approved SSDs which are OEM versions, or third party user installed SSDs replacing the hard drive that was shipped). It's possible OS X may use TRIM in a way that it doesn't trigger the bug. Or maybe it does it less aggressively than Linux, so the bug incidence is far lower and no one noticed it yet.
All we know is that Linux definitely triggers the TRIM bug, OS X and Windows doesn't, yet (but there are no guarantees that Apple or Microsoft won't change the way Windows 10 or El Capitan does TRIM which WILL expose the bug).
The bug is in TRIM. That's all, if you don't use TRIM, it'll be fine. Maybe even using fstrim periodically is OK over using discard mode.
I'm waiting for the patent on Apple's original iPod connector to expire so I can get a portable media player compatible with it.. or by then, everyone will have forgotten about it.
Don't get your hopes up.. I don't even know of a single media player compatible with the iPod connector.
Yes, the fact that Apple only uses TRIM on Apple-approved SSDs leads one to infer that there is indeed something buggy about TRIM under certain conditions, and Apple only tests for functionality on their OEM drives. Or it's just Apple being dicks, as usual.
From TFA: "Samsung guarantees the 2TB 850 Pro for 10 years or 300 terabytes written (TBW), and the 2TB 850 EVO for five years or 150 TBW."
So the warranty is limited to 150 write cycles regardless of age for the Pro, and 75 for the EVO. That doesn't sound good to me.
i'm not talking about encryption, you fool! i'm talking about firmware! why else would i write "permanently infected" if not to say it was firmware?
Anons need not reply. Questions end with a question mark.
Actually, a recent article showed that SSDs are much MORE reliable than PCs (I think it was Backblaze). They just aren't cheap enough for many applications yet.
Peter predicted that you would "deliberately forget" creation 2000 years ago...
PC=>HD. Sorry.

Or, easier: Someone should market some simple extension cables, ala the original Xbox's controller cords.
Trip over the cable? No problem! It orients itself automatically to be easily unplugged mid-span, and neither the laptop nor the person take a spill.

While I agree with you for the most part, why do you say Hardware RAID instead of Software?
The historical reasons for not using Software RAID (via mdadm) have long been resolved:
What, then, is the advantage of spending hundreds (or thousands) on a RAID card and introducing another point of failure?

Since TRIM is a standardized command, SSD vendors either need to support it, or like is done with the format command on IDE drives... do nothing, return a success value.
They do support the TRIM command.
The "bug" is how TRIM and command queuing interact (specifically a race condition labeling the wrong logical sectors RZAT/DRAT) I put "bug" in quotes because the specification specifically says that TRIM is a non-queued command. Windows/NTFS makes sure that the queue is empty before issuing a TRIM. Linux/EXT4 does not.
Ideally the drives should make sure that their queue is empty themselves, but it likely takes a tortured reading of the specification to think that compliant drives will make sure that their queue is empty.

And the 10 year warranty that interest me - running a 32Gig SSD drive for a week I lost 48K of the drive.
It's or bytes written.

My intel died in a year.
Intel has a reputation for backdoors like VPRO/VT/AMT, not reliability.
I still prefer hardware RAID because of trouble I had with those legacy issues yes, but I also got very used to the convenience of letting the RAID card manage the storage and having Linux only deal with the device the card presented to it instead of managing each drive. I also think the RAID cards' management software and hardware monitoring is superior, I've had a few software RAIDs have a disk fail without proper alerting and had more than one close call as a result. This newest info on the SSDs having problems is just more icing on the "yep, my way is the right way" cake. YMMV of course.
Not putting all my eggs in one basket. Imagine loosing 2TB at once.
Personally I use 100s of 8GB drivers and a nest of usb hubs and adapters. When they die (a few per week) I only loose a few GB.
