I've had motherboards with options for faster bios booting, which would go from power on to windows startup in a couple seconds. Win7 and a much older SSD so not super fast after that, but the bios was quick.

I always turn those things off though, I only reboot my desktop once a month so don't much care about boot time. And I like having more time to hit whatever key for bios setup.

They come down pretty good in price from time to time.

Does the warehouse deal make them cheaper than a new Evo or equivalent TLC NVMe drive? Does your use case actually need a Pro?

One of those would have to be a Yes for me to consider it.

On a system with just a SSD you really want to keep their free space needs in mind, because you don't have a spare drive to throw downloads or other temporary crap.

So if 1TB is going to be 90% full right off the bat with your current stuff, that will be a thing to work within. Not a deal breaker but a thing you'll want to manage. How much free space your SSD needs depends a lot on your use patterns.

OTOH when adata puts stuff on big sales you might look at it as a leading indicator. They get all their flash from the fab companies with recognized names, so their bread and butter is previous-generation stuff that's being replaced, or surplus stock.

So if you need a 1TB drive right now go for it. I'm really not sure why they're so prominent on the bad list vs other no-nomes like Silicon Power or Patriot. They use slower controllers and have DRAM-less drives (pretty sure that SU650 has no dram). That's what you're paying for, or rather not paying for. There's definitely been times where their crap drives are only being sold for a small discount vs something like an Evo at which point they're a bad buy. I wouldn't buy that NVMe one for example.


But if you're just idly considering moving to all solid state or impulse shopping, I'd say hold off. All the reports are that there's a flash oversupply, plus stuff like QLC coming out that's gonna push even more downward price competition.

It's notable because the seagate drives of that series are now known to be poo poo for reliability. But not quite so poo poo that it's worth pre-emptively throwing them away like the old deathstars.

Just had a bit of a scare with Crucial M4 in my mid-2012 Macbook Pro. OS hard-locked, rebooted, no drive visible to the computer. Tried another drive and it was visible. I was about to order a replacement when I came across a forum post about resetting the M4 by leaving the computer powered on to BIOS (or in the Mac's case, boot selection screen) for 20 minutes, powering down, removing the drive for a minute, then putting it back in. Did that and voila, the drive's back and seemingly fine.

Buuuuuut now I'm concerned about it. Has anyone experienced this with an M4 and found it to be perfectly fine afterwards? Should I go ahead and replace the drive anyway? Would I see better performance out of a newer SSD like an 860 Evo or an MX500, which are both nicely priced on amazon?

Thanks, folks.

The M4 was the reason that Crucial was on the avoid list in the old thread. This was a known flaw in that drive that starts showing up after 5200 hours of use. So as far as data integrity it's ok, but IIRC they never really fully resolved the wonky stuff going on with that drive. You may run into this problem again.

At the very least you should update the firmware.

On a 2012 macbook a newer SSD isn't gonna do much to make it feel faster, that thing is just old. However, I personally wouldn't feel great having an M4 in my primary system.

Is there any benefit to doing a fresh install of Windows onto an SSD over migrating the OS from an HDD? I used Samsung’s migration tool with what was already a pretty fresh Windows 10 installation, so if there were a benefit it wouldn’t be too big of a deal to just do another fresh installation.

A minor one: SSD have a small performance gain when they align the file system's allocation units with the SSD 4kb pages*. I think windows 10 is now smart enough to do that automatically at install on SSDs (it's been 3/3 correct for me). I don't know if HDD partitions migrated to a SSD would be.

The problem with that Silicon Power drive is that it's a complete mystery what's inside it. They say MLC NAND, which makes me think they're the remainder stock of drives with a 2014-era Phison controller and Toshiba 2d NAND. If so, those are old and weren't good even when they were new. However, it's fine for light applications -- where they completely fall apart is mixed random read & write stuff. If your laptop is just an internet / email / netflix / typing machine that's ok.

But they also say SLC cache, which is a real wtf. Maybe they're calling the DRAM a SLC cache? Because the old S60 at least had DRAM, which is why they're still better than an Adata SU650. But if it actually has a SLC cache this is yet another set of new grab-bag guts.


My biggest worry if I were considering buying it would be that they've been sitting around some unconditioned warehouse a few years of temperature swings.

But mostly I just wouldn't buy a 2tb nvme drive right now. Those are still a halo product and the crazy price-war discounts aren't hitting them like smaller drives. $500 for 2tb is a bad deal when 1TB satas are being sold for under $150 and even 1tb nvme can go on sale for $200.

NVMe is faster than sata, a lot faster. But average desktop and gaming stuff is not constrained by the bandwidth limitations of sata so it's not really visible. During a level load a sata SSD can supply data fast enough that the game is spending more time waiting on the CPU and memory while setting up the geometry and stuff.

For now the performance advantage of NVMe is useful to people doing databases, high-end video editing, servers, etc.

it's going to be annoying having to explain to people in the building thread that the "QVO" drives aren't meant to be boot drives, though.

"But it's cheaper!" :downs:

What exactly makes them unsuitable as boot drives, for the average desktop & games goon? The ones one the market already from Intel & Corsair were pretty much tuned specifically for mainstream (ie read-heavy) desktop performance. You don't need to worry about the page file consuming too many writes or whatever, it'll generally stay in the SLC cache which doesn't burn the write capacity. At the most conservative, maybe you go back to recommending that people short-partition the drive by 100mb so it always has spare space, since the worst problems occur when you fill the drive enough that the SLC space is restricted.



Personally I'm not very excited by the first-generation QLC drives. The current ones are just "NVMe at sata prices" but I'm already fine sticking with sata. And I think future improvements might come along that make the limited-writes problem even less of a problem -- for example, if the OS / filesystem could give "hints" to the SSD about temporary vs permanent data. But the history of TLC suggests that gamers & PC enthusiasts are really bad at estimating drive life and how fast they'll go through it. People used to say not to buy TLC drives because of endurance, and they were wildly wrong.

Why the hell are we worrying about writes? Even TLC drives of moderate (256+GB) sizes have effective write tolerances so hilariously high compared to normal consumer workloads that they will far out last the rest of the computer you stuff it into. It's worth actually looking at what an average persons disk writes per day are. For most home users, it's actually quite small.

I mean, the Samsung 840, a first-gen TLC drive, went out to 800TBW on a 256GB drive before it died. The QVO drives are advertising about 1/2 the endurance of TLC drives, which even if true, means that they have plenty of write cycles available for Joe Consumer.

The new drives we're talking about are QLC, four bits per cell. Currently the Intel 660p and Crucial P1 are on the market, samsung announced they're doing QLC too.

The first-gen QLC is being spec'ed with 20 writes per cell. Yes, twenty. That would seem to be a problem because even a mainstream user might write 20 or 40 TB. But they are also using the SLC cache that Evo-style TLC drives do now, only with even more smart management to dynamically size the SLC cache. Because the SLC cache can be pretty huge, the drive is less aggressive pushing data into QLC storage. Writes in SLC mode put a fraction of the wear on a cell that quad mode does, so the effective endurance is fine for mainstream desktop use.

Intel is selling the 660p with a 5 year warranty and 200TB write endurance limit. And Intel is the most conservative SSD maker about write endurance.

Turns out I wasn't crazy, after all. Just slightly misremembering things posted ITT a year ago (emphasis mine):

And then the part I forgot a few posts later:

So all that time ago I was going on the reported results from the one place I've seen that actually ran through all that write capacity, TR's endurance test. Their intel drive did not become a permanent read-only drive, it bricked itself into "an inaccessible 0GB SATA device". TR did an immediate reboot after it started throwing errors and then it was dead.

quote:

According to Intel, this end-of-life behavior generally matches what's supposed to happen. The write errors suggest the 335 Series had entered read-only mode. When the power is cycled in this state, a sort of self-destruct mechanism is triggered, rendering the drive unresponsive. Intel really doesn't want its client SSDs to be used after the flash has exceeded its lifetime spec.

I don't remember if anyone ever posted firm evidence that newer Intel drives have changed to permanent read-only. Or whether TR's experience was not what was supposed to happen and their drive was faulty. I don't think it's a huge deal because, as we've been discussing, drives have more than enough write endurance. But I still think self-destruct is a lovely feature. Also that nobody should rely on the read-only feature for data recovery, in the unlikely event that they run through 100% of the MWI.

Ok cool. That is much better and removes my negative outlook on that "feature".

I know people say backups, but in practice very few people run constant nightly backups. Even a small amount of lost data is bad when it's from something that was completely avoidable.



(As an aside I think small QLC drives -- like the 256 in that article -- are a bad idea, and worth avoiding or recommending that other people avoid. The SLC area is much smaller, and the drive is more likely to be full which reduces it more. Everything that makes QLC acceptable is the SLC zone. The discount is gonna be like $5 on small drives so not worth it.)

I'm using it in a Mac Pro that's my normal machine, but heavy sustained workloads are somewhat rare for it, and I'd rather not reduce the lifespan of the EX920 if I interpreted all of the information right.

Quick GIS of that looks like an oversize heatspreader, I'd just leave it. In a mac pro -- the trashcan one right? -- it's gonna stay pretty warm since the ambient temperate around it is gonna be pretty toasty.

Also the thing about flash memory preferring to be warm is about data retention time, not overall flash lifespan. Worse data retention does theoretically lower total lifespan, because the controller has to re-write data that is getting fuzzy*. But that's a trivial number of writes added, versus endurance that's far more than what almost anyone will need.

*this is why SSDs are not recommended for unpowered offline backups, because they can't do that while they're sitting on a shelf

These days overprovision should be tailored to your tasks, not a strict % of drive space. If you have 100GB overprovisioned and you never write more than ~50GB in any operation it is more than you need. 10% was a reasonable number from back in the days when $1/GB was cheap and people had tiny ssds.

Personally, I overprovision my drives by formatting them to divisible-by-5 in gibibytes, so that the drives have pleasing numbers when I look at them in explorer. And yes, this means that my HDDs are also "overprovisioned".

IIRC games and particularly consoles were one of the bast use cases for those hybrid SSHDs that seagate makes, because even the small amount of flash they have is good enough for the predictable caching needs of a game or console os.

Thanks, that makes sense - drive is like 80% empty, and there's no bad block/realloc errors at all in smart.

But with the huge cache hit ratio I was wondering if the SLC/ncache portion of ~15GB (described here: https://www.techarp.com/reviews/1tb-sandisk-ultra-3d-ssd-review/2/) was getting smashed apart. But further research puts SLC at 90-100k writes before an issue. (So like 125-150TB)

AFAIK the SLC isn't a static area of the NAND, it gets moved around to work with the overall wear leveling. Newer drives don't even have a fixed size allocated to SLC mode. Writes in SLC mode are much less damaging to the cell, much like getting hit with a bat is nicer than getting shot with a bullet. The bat and bullet might have the same amount of kinetic energy, but the bullet is more concentrated.


Some SSDs *do* slow down over time with lots of data written. In many cases it isn't even the NAND itself wearing out, because doing a ATA Secure Erase will restore performance. OTOH some SSDs actually get faster!


So if you wanted to try to restore performance you could backup the drive and secure erase it. Alternately, I wonder if the constant writes are making the drive less efficient at its internal reorganization & garbage collection? If your application is able to be paused, you could stop it and run a trim periodically and see what that does.

Nope, lots of them do it now. The mx500, 970 Evo, even the Adata SU800. All QLC drives are relying heavily on dynamic SLC area to make QLC not suck. They may still have a static number which is the fixed minimum size of SLC even if the drive is full.

The cells that get used as SLC are the same as all the others, just programmed differently by the controller.



VVVV edit: I honestly didn't know myself it was so widespread! I found out the mx500 could do it just now when I was trying to look up more examples other than the 970 and 660p. It's very cool how SSDs have gotten to the "don't sweat the details, the drive is smarter at managing itself than you are" point in such a short time. :tipshat:

Has anyone purchased an Inland Professional drive before? I’ve never heard of the brand and Microcenter has a 1tb model for a little over a $100, which seems like a pretty good deal. Not sure if anyone has horror stories about these blowing apart and showering their genitals with hard drive shrapnel. I’m swinging by Microcenter tonight to pick up an order and I was thinking of purchasing one to supplement my 500gb Samsung drive.

It's a cheap dram-less drive, so fairly poky for an ssd. Fine as like a games drive or something.

1tb for $100 isn't a super deal though, the Adata 650 (also dram-less) is $100 on newegg. And prices are expected to continue going down this year. In particular I wouldn't bother buying a cheap slow SSD right now when more QLC drives are on the horizon.

You may have seen my post in the general hardware questions thread, I'm 99% sure this is not possible, but is there a mini PCI-e SSD that I can install in the second PCI-E port of my HP DM1z? I already have a few 2.5" SATA SSDs laying aroun (and even one installed in the DM1z) but I would love to have both an SSD and a spinner in the old laptop. I think the hardest part is if I search for mini pci-e SSDs I get results for mSATA SSDs which I'm certain would not work. I highly doubt the DM1z BIOS would allow booting to a PCI-e SSD, but maybe I could convince GRUB (running Xubuntu since it's too slow for Win 10) to boot to a PCI-e SSD. Worst case scenario, if I find a mini PCI-e SSD and my DM1z refuses to acknowledge it, would I be able to cobble together an adapter to use it as a regular SSD in either the laptop or a desktop PC?

I don't think so. That laptop has an extra PCIe slot (besides the one taken by the wlan card) but the AMD chipset from 2011 doesn't support NVMe. So it won't even recognize a PCIe/NVMe card. And I doubt the slot is wired for SATA -- no references to it on google anyways. If you could get your hands on a M.2 sata card I would try it just to check, but don't pay for anything you can't get a full refund on.

Laptops with CD slots (or blanks where a CD could go) you can get an adapter allowing a 2.5" drive to be installed.

PCIe 4x -> one NVMe M.2 is simple, it can be just a board with passive wires. a cheap one is fine.

PCIe 16x -> 4 NVMe M.2 slots is not simple. It either needs a PCIe switch, or your system needs to have that capability built-in. (Ex this asrock card has a real short support list and only works "normally" on threadripper systems, on Intel it needs to use their Virtual RAID on CPU.)

Cards with switches are expensive. e: and still don't work in an average consumer level motherboard apparently?

He's asking for SATA ports though which should be a hell of a lot easier. A quick and dirty search has a 2 port card for $16 and 4 port for $25 on Amazon.

hahaha I got totally befuddled by the previous guy asking about raiding NMVe drives


IIRC the thing the DIY NAS server guys always recommend is to buy a cheap surplus LSI card off ebay (or IBM rebrand) and flash it to the non-RAID mode. You end up with a fast & reliable controller card that allows you to build whatever type of storage array you want in the OS.

The cheap $30-40 sata cards on newegg are all powered by a cruddy marvell chip that doesn't hold up to real workloads. don't get them.

Also that motherboard won't be able to boot from the NVMe drive (common problem for z77 chipsets) so you can't move your OS onto it.
