Hatter106 posted:Thanks guys! Yes, just plug the SSD in, remove your old drive (while installing) and that's really it. However one important thing to do before you begin installing Windows: Enter your BIOS setup, and make sure the SATA controller is set to run in AHCI mode. If it isn't in AHCI mode, then important performance features like TRIM and NCQ can't work, and changing to AHCI after installing Windows usually requires a full reinstall.

Just for a fun test I copied a 600 MB folder that had 17,000 files in it and pasted it into the same location. On my HDD it took 2 minutes and 40 seconds. Then I did it again using my MX200 and it did it in 20 seconds. I'm really disliking HDD's as a backup media.  So I was looking at these: A Samsung Portable SSD T1 costs £350 ($550) and gets write speeds of Seq: 416 MB/s and 4k: 40 MB/s And a Samsung 1.0TB 850 EVO costs £290 ($450) and gets write speeds of Seq: 518 MB/s and 4k: 140 MB/s ...The "why is there a SATA cable sticking out of your tower" way of pricing. Why the hell would I use a T1 when we have hotswapping/hotplugging sata3's?

Long term data retention without being powered up is not the strong suit of SSDs. I'm not saying it won't work, but it's just not a great idea. If you're annoyed by how long it takes to do a full backup every time you swap your active backup drive for an offsite... maybe don't do that? The full backup I mean. IDK about the Windows built in backup software or whatever it is you're using, but if it's halfway decent you ought to be able to just do an incremental to the drive you're rotating back in to catch it up to the present.

Right now, we're operating 22tb of raw flash over 4Us of rack space. That...that's nearly as much in a single 2.5" drive. I cannot wait to see the pricing on these drives.

Pricing? Bound to be absurd. All I want is a 3TB SSD thats 80% as fast and endurance rated as my 850 Pro for ~$600 or $200 per TB whatever. Would even glady accept 3.5'' form factor.

quote:Samsung showed off a server with 48 of these new SSDs, with a total storage capacity of 768 terabytes and performance rated at 2,000,000 IOPS (input/output operations per second). By comparison, the consumer-grade SSD that you have in your PC is probably capable of around 10,000-90,000 IOPS, depending on the workload. Is that right, only 2 million iops from 48 drives ? seems a bit low as compared to pci express flash drives doing over a mil on their own.

Any good choices for hybrid drives? Old 120GB SSD is a bit limited in a casual user's PC, speed isn't crucial and having to mess around with two disks seems unnecessary.

I'm not saying it won't work, but it's just not a great idea. Hmm, I never considered the effects of long term offline/unpowered storage of an SSD. I only do a full backup every other month or so but by then the differential/incremental (which ever windows uses) gets longer and longer to backup.

I know that ( which is why I specified pci-express in my post ). I was surprised by how slow the new drives are, or how inefficient raid / jbod over that many drives is. An evo 250 can get ~90,000 iops over SATA3 so theoretically 48x 90,000 is ~ 4 mil. I thought a next gen product would be quicker.

JBOD wouldn't be quicker in any way, it doesn't sliver the data. And even if it was a giant RAID-0 array, there are limits on how fast AHCI and SATA chipsets can work.

At this point there could be a difference between the OSes they used for testing. There are some quite substantial differences between Windows and Linux in the max IOPS count due to differences in the driver stack between the two.

Shiny new SSD arrived by Amazon yesterday and I thought I would do a very easy install: keep everything intact on my HDD, clean install on SSD and play around with boot order in the BIOS to swap between the two (eventually wipe the old install off the HDD and as it as data storage.) Didn't go entirely smoothly: 1) mounting/cabling kit arrived a day late. Thanks Prime. 2) brainfart and didn't unplug the HDD when installing onto SSD and ended up with a dual boot system. Had to reinstall the new installation. 3) took me far too long to remember that with a fresh install, my onboard wifi will appear to be working fine, it just won't connect. 4) installed my USB wifi dongle. Oddly, the dongle wouldn't work, but the Asus wifi client allowed my non-Asus onboard wifi to work. Then it got very weird. Would not boot up beyond the BIOS bootscreen, just froze there without error message. Eventually found that if you hit the DEL key, it would go to BIOS setup after a long (multiple-minute) wait. BIOS was frozen......no, it was taking a full minute to process each keystroke. Never encountered that before Cleaned the dirty heatsink/fan incase I had dislodged fluff and clogged the flow of heat. Nope. Swapped the keyboard to different USB port. Nope No joy. Eventually got it working and now just have to install 207 important updates it was the wifi dongle. It chose that exact moment to stop working. Not only would it not work in windows, having it plugged into the USB port would cause the motherboard to grind to a halt at the BIOS setup. I don't even know how that is possible

So I'm pretty confident my SSD is on its way out but I'd like some confirmation before I drop some cash on a new drive. I've got a 2012 13" MacBook Pro running Yosemite that gave me the "Prohibitory" symbol last night and refused to boot up (I think it's apple's blue screen of death). I've been through all the steps of trying to reset NVRAM and SMC but it wasn't until I opened it up, disconnected the battery and inspected the hard drive connections that I was able to actually get it to boot up in safe mode. Back when I first picked up the macbook I swapped out the optical drive with a harddrive bracket, placed the stock 750gb HDD in that slot and replaced the main boot drive with a Sandisk Extreme 240gb SSD. Used the SSD for OS and applications, saved all the documents on the HDD, everything has been working smoothly up until now. I wouldn't think 3 years is enough time for the SSD to go through its life cycle, I'd read in earlier in the thread about cheap faulty cables being a possiblity but I figured that was mostly applicable to tower builds. The laptop is obviously using fancy pants model-specific form-fitting ribbon cables so I'm looking at ~$25 for even a third party cable. Seeing as the cable is routed over this third party harddrive bracket I could see how it might rub the cable the wrong way but it seemed intact when I opened it up earlier today. At the moment I'm able to get it to boot up (and backup everything to an external disk using Time Machine). Using disk utility I'm pretty positive it's the SSD (or some connection) that's giving me poo poo as it's not entirely recognizable and I don't have the option to repair or mount/unmount it (whereas both are available for the HDD). Previous to all of these rebooting and resetting shenanigans I could boot directly to disk utility and the SSD was read only as "disk0". What's next? Is there another way to confirm it's the drive and not the connection? I'm able to limp along at the moment but the drive still won't mount, don't know what that indicates. Assuming it's dead and I pick up one of those 850 Evo's to take its place, has anyone here had experience restoring from a Time Machine backup? Am I going to have to hook up the new drive externally and drop a bootable OS on it before I'm able to backup? Is it possible to get a bootable drive from a failing SSD? Thanks in advance for any suggestions. Sandisk 240gb SSD:  Stock 750gb HDD:

Samsung 850 Pro 256GB SSD available from Amazon UK today for £70.67, which is cheaper than the EVO 850 250GB version. It's from a third party seller so the price will likely rise once they're out of rotation or stock, or however Amazon decides these things. http://www.amazon.co.uk/dp/B00LMXBOP4/ref=wl_it_dp_o_pd_nS_ttl?_encoding=UTF8&colid=3SNJLG2NFXT8P&coliid=ISIKWIFBLCZEJ

I got a Samsung EVO 850 500GB a few weeks ago during a Newegg sale and it's been working fine until today. The drive just stops showing up after a while, even if I restart the PC where it doesn't even show up in POST. In order to get it to show up again I have to turn the PC off and back on again. This PC was just updated from Windows 7 to Windows 10. Any suggestions as what I might want to look into to fixing it? Taerkar fucked around with this message at 17:59 on Aug 15, 2015 |
