  1. While we didn't hit the WD posted performance of the My Passport SSD, we did see aggregate performance that puts the drive in a very favorable position at the head of the class. As professionals and consumers do more on the go, the portable SSD segment is going to rapidly grow in importance to vendors that deal in flash. WD is well positioned then with this effort not just in terms of performance, but in other elements like the software package for PCs they include and a design that is appealing.

  2. The main use cases for the new Ultrastar SS300 drives are virtualized storage systems, databases, and private and hybrid cloud environments. The drive come in capacities up to 7.68TB, enabling customer to consolidate their data centers a bit and get the same data in a smaller footprint. Not only does the new drive have high random performance and high capacity, it is also offered in several endurance classes and power settings (high power consumption for more performance and lower for energy savings). The levels of variety give OEMs lots of flexibility as they create data center gear. WDC Announces HGST Ultrastar SAS SS300 SSD
  3. The P4800X is being shipped now in directed availability and is expected to be generally available in the second half of this year. MSRP for the current 375GB SSD is $1520, though pricing will depend a good deal based on volume. Intel Optane SSD DC P4800X Enterprise SSD Launched
  4. Hello Everyone and good day J I'm trying to decide between two ssd drives I Adding an images of this 2 One is "SanDISK SSD PLUS MODEL SDSSDA-240GB SATA 6G/s " THE OTHER IS " SanDISK X300s SD7SB3Q-256G -1006 " i have a couple of Questions 1) Which one is better ? And newer ? 2) If I connect them to pc the one with 240GB show only 223GB and the one with 256GB Show me 238GB It’s a 15GB Difference in Capacity storage IN THIS CASE What you recommended ? 3) they both sata III (3) ? if no , its Critical difference between sata 3 and sata 2 ??? 4) I plan to used the ssd drive with adapter cable usb Directly to computer like an External Hardisk to backup some files and stuff it a good idea ? USB adapter connection speed will not fall down? 5) Maybe After a while I'll use it to connect internal hard drive for the operation system so which one better for two cases I appreciate your help and want to Thanks in advance everyone
  5. Has anyone tried the ICYDOCK product MB610SP? This is the item . I cant find any reviews for it. I want to see if it is a viable item or not. There is a similar item but I'm not sure if it will be equally worth. Has anyone even heard of the company? If anyone knows about it please let me know.
  6. I used to have 256gb 'boot' ssd + 2x3TB HDD Windows Storage spaces in parity mode. I deleted a Windows storage spaces virtual volume (was set to parity), took out one of the drives and partitioned the remaining drive with a simple ntfs volume. Now the drive keeps getting offline and the only way to reconnect is to use the command line diskpart tool or reboot. I suspect this is something to with the HDD still having the same ID as the old Windows Storage spaces had or something similar to that or a sign of an actual hardware issues (faulty hdd, faluty cable). How do I properly reset the HDD, do you also think that this may signal some sort of hardware issue with the drive as well. SMART seems to be ok, even when drive is offline.
  7. Samsung continues to set a high bar with its storage products. The company has released the highest capacity M.2 drive for consumers, for the second year in a row (last year they were the first to release a 1TB M.2 and this year they are the first to release a 2TB M.2 for consumers). On top of that, the drive has record setting sequential performance, the highest we've yet to test on the consumer side. The 960 PRO's form factor is ideal for where the market is heading. The only real downside to the drive, is the same downside to all new technology, early adopters will pay the price penalty, with the 2TB MRSP of $1,299. Samsung 960 Pro M.2 NVMe SSD Review
  8. In short- why should we care about IOPS?In depth- this is what i don't understand:I've read quite a number of articles and forum posts regarding this issue and couldn't come to a conclusive answer.Basically, in order to know if the IOPS is a limitation one would need to know how many IOPS are needed by the machine.I couldn't find any relevant information on that apart from Database info like this: which states 2000 IOPS as a typical workload.This article states that IOPS in flash (SSD) is practically unlimited and since latency is also not an issue in SSD's, it seems that the only relevant measurement is Throughput. comments are really interesting too.This also seem to follow the same lines: thing is, all these articles are from professional storage point of view and they talk about it in the relation with an array of physical disks in a data center and such.What I'd like to know is weather these figures means anything to mortals?I mostly do video editing and grading.I tend to think that the following is an ideal setup for me (drives wise)1. OS and Programs- 250GB SSD2. Media cache- 250GB SSD3 .Media drive for hot projects- 1tb SSD or 2 500GB SSD's in RAID 04. Data drives (backups and all other stuff)- FreeNAS server with 6 8TB NAS DrivesLet's concentrate on the SSD's.On the OS drive and the Media cache drive I'll be doing mostly small reads and writes.On the Media Drives I'll be doing very large Sequential Reads (Video files).Currently I have only one SSD which is used for OS, Programs, and media cache. This is on a Intel 520 series 240GB drives which is rated at:Sequential Read (up to) 550 MB/sSequential Write (up to) 520 MB/sRandom Read (8GB Span) (up to) 50000 IOPSRandom Write (8GB Span) (up to) 60000 IOPSFor comparison, the Samsung 850 EVO 250GB specs are this:Up to 540 MB/s Sequential ReadUp to 520 MB/s Sequential Write Up to 97,000 IOPS Random ReadUp to 88,000 IOPS Random WriteI want to add the next SSD on the list which will only serve for media cache. Later on (budget you know) I'll add the large 1tb hot projects media drive.I'm thinking of getting the Intel 600p Series 256GB M.2 SSD which is rated:Sequential Read (up to) 1570 MB/sSequential Write (up to) 540 MB/sRandom Read (8GB Span) (up to) 71000 IOPSRandom Write (8GB Span) (up to) 112000 IOPSRegarding all the information above, will it be better suited for the OS, for the Media Cache, or for Media drive?And could somebody please explain why everybody is talking about IOPS? How is that important? How is that a limitation in this kind of setup?Is there an application that needs 50,000 IOPS?? What is a normal IOPS rate?This also begs the question, why should we consider "Pro" drives like the Samsung 850 Pro or the Sandisk Extreme Pro when their throughput is essentially the same?Besides reliability, what's to gain from this drives in terms of performance?Sorry for the long post...Eli
  9. I'm trying to understand what it means to boot into a GPT-initialized disk on UEFI system. In the world I live in Windows only boots to MBR disks. But I keep reading that it is possible to boot using GPT. Few questions arise: UEFI seems to exist only if the hardware supports it. How do I check if my (new PC, HP Z440) has it? How does booting to GPT work (there's no boot record!)? The real reason I bring all this up is because I am trying to install Windows 10 onto a brand new SSD (OWC). I failed. Here are the details: When 1st plugged in, the motherboard didn't even recognize the SSD Then I plugged it in via USB and it was seen. I mirrored my existing drive onto using Acronis When I plug it back into SATA and try to boot, I get irql_not_less_or_equal error (which is a driver error, when it tries to access an illegal memory address space, from I've read) I'm trying to update the firmware on the drive now, which could be a solution I am exploring options to get this fixed, thus the questions about using GPT.
  10. How much performance do you lose by running NVMe devices over Ethernet or InfiniBand compared to running them natively? We did the test using ConnectX-3 adapters on Ethernet and InfiniBand. Here are the results:

  13. Hi all, I work for a small sized (but quickly growing) school district and we have some aging hardware that is in need of some love. From a processing and network viewpoint these servers should still have plenty of life left in them (for us at least). Rather than buying all-new servers, the thought was to put in some SSDs and RAM to breathe some new life (and performance!) into them. However, after doing some research it looks like the RAID controllers currently installed only take up to ~12GB SSDs (~36GB after a firmware update), so that brings a few questions to mind: 1) Is this size limitation only if using SSDs as cache drives? Would they recognize modern SSDs as 'normal' hard drives with no such size restriction? 2) Is TRIM still an issue with SSDs? or do modern controllers pass TRIM commands? Or does it depend on the specific hardware in use? 3) If I need to replace the controller, what would be a good make/model? I have only ever used onboard Intel RAID, or whatever RAID card comes with a server... I am a little green in this area. They would need to control up to 8 physical drives (2 arrays) each, and I believe the current controller is in a PCIe2 8x slot on the motherboard (will verify tomorrow). 3) Would we be able to get away with using relatively cheap consumer grade drives (like Samsung 850 Pro) instead of straight-up SAS HDDs or SSDs? Our write load is not very high, mostly read operations on databases and running several lightly used VMs on each box. 4) I have typically used RAID6 (or equivalent RAIDz2 or RAID5+1) in servers up to this point so we can take up to 2 drive failures. However in doing a little research everyone seems to think that RAID5 is perfectly acceptable when using SSDs (Intel's website specifically suggests NOT using SSDs in RAID6 and to use RAID1 or 5 instead). Is this generally true? Or should I still be looking at a RAID6 setup for redundancy? 5) My first thought is to make the system drive on each box a RAID1 with 2 SSDs for performance and redundancy... but while that makes sense on a desktop computer, would that affect anything other than the boot time on a server? These are all on battery backups, so they don't shut down often, and boot time is really not a priority. Should we save the money and buy HDDs for the boot drive? Other potentially important info: There are basically 3 servers I am looking to upgrade. Server 1 is for file shares and will just have a bunch of ~1.5-2TB HDDs (server takes 2.5" drives) for the data drive. Performance is not such a huge issue here, the big concern is in bulk storage and redundancy. SSD use here would only be for the OS drives (RAID1) if it would offer any real-world benefit. Server 2 is going to be a HyperV box (nothing against VMWare... we just have more experience using HyperV and are less likely to break it lol). This will hold the VMs with the databases on it, and I would like to put in all SSDs. If we can use high-end consumer SSDs then I would like to put in 4-6 drives in a RAID5 or 6. If we have to use SAS drives then I might just buy 2 larger (512GB) ones and put them in RAID1 Server 3 is going to be another HyperV box for our more pedestrian VMs (print servers, DCs, applicaiton servers, controllers, etc.). First thought is to just buy new HDDs and be done with it... but if we can use something like the 850 pro SSDs then I would like to make Servers 2 & 3 identical. Depending on when this project is complete these servers will either be running Server 2012r2 or 2016. If you need more specifics (make, model, etc.) I can look that up when I am in the district tomorrow. These IBM servers all take smaller 2.5" drives instead of normal HDDs I don't have a specific budget yet, but we are probably looking at $5K or less (preferably much less if I want the district to agree to it lol) in total upgrades to these boxes. That includes drives, controllers, ~100GB of RAM, etc. When I am done I am hoping to consolidate 14 physical servers strewn about the district into 5-6 boxes total. Should be a fun project Thanks for your time everybody!
  14. When I friend was looking for an SSD upgrade, I took advantage of it and sold my 'pedestrian' SATA SSD and replaced it with Samsung 950Pro connected via an adapter in a PCIEx16 slot. It took some wrangling but the drive is bootable on a Z87 board and is generally working fine. I ran some benchmark with Crystal DIsk Mark etc and they are more or less in line with reviews. However, when doing simple tasks, I'm not entirely impressed - for example I recently downloaded a zipped file - a compressed linux image. (650MB uncompressed) I wanted to unzip to the same folder and saw speed around 2-3MB/s, not exactly what I expected. The same goes for very small files - something that I'd expect to be instant. I check the activity monitor and CPU was hardly used, so clearly it is the SSD that's bottlenecking somehow? Finally I have 24GB RAM so I would expect Windows 10 to take advantage of that to cache recent files in RAM (such as the one I just downloaded)? Is there a way to investigate what's going on? I should probably add that while there is no radiator, the SSD is pretty well ventillated and running benchmark for longer indicates that there is no throttling even under have load for at least 10 minutes. The rest of the system: CPU i5 3.4GHz quad core 24GB DDR3 #1600Mhz c: - 256gb Samsung 950 Pro PCIE 3.0 x4 d: 4 way raid-0 - 4 x 500gb Sandisk Ultra II SATA SSD s: - 3TB backup HDD (nightly backups of d: and some folders on c: using CrashPlan - I temporarily turned it off, but no change) As you can see I have spare disks attached so I could create an image and perhaps reformat with a different stripe size perhaps?
  15. Hi All, I am looking to purchase a NAS system that I can plug in a few SSD into. I mainly want it for pictures, videos and work documents. I am thinking of purchasing the Synology ds1515+ with 5 Samsung 850 Pro 2TB. Will this work? Thanks
  16. There was a study presented on Google's datacenter SSDs as of late: Conclusions are interesting: SLC not more reliable than MLC 20-63% of SSDs develop a uncorrectable error in the first 4 years and 30-80% develop at least 1 bad block Drives tend to have few or many bad blocks Replacement rates for SSDs is lower, but their rate of errors is higher Anyways, the full study is worth reading. I suppose though that there is no real benefit in keeping SLC.
  17. Are we going to see a flood of NVMe SSDs this year? I think we've reached the point now where there are going to be more mainstream SSDs. I am hoping that the price premium goes away (ex: price per GB is comparable to say, an SSD 850 Pro). I would like to see 4k Rnadom @QD1 performance go up. The new drives look plenty fast too - RevoDrive 400:
  18. I'm curious, we seem to have a considerable market now for MLC and TLC 3D NAND that is typically in the 40 nm range.. for flash size. Is there any 3D NAND plans for SLC? Or is SLC dying to such an extent that there seems to be a loss of interested for SLC in general, even for the most write intensive applications?
  19. Hey folks! I'd like to kill two birds with one stone and upgrade my OS from Windows 8.1 to Windows 10 (with a clean install) and "freshen" my SSDs at the same time. I have 4 x 256G Samsung 840 Pro SSDs in hardware RAID 5 (LSI 9750-8i) and it was quite fast and responsive when I first installed my OS but now it's kinda... meh... As we all know TRIM isn't supported in hardware RAID and GC isn't as efficient. Supposedly, Samsung's GC runs when system is idle and people have said for it work you need to have the system running but logged out (as oppose to just locked) but I have my system on 24/7 and only locked when away... that's a lot of degradation in performance. Anyway, I'd need to know if anyone with experience with SSDs and hardware RAID recommends any certain action to be performed prior to re-installing an OS, other than a straight-up formatting. Something to return each individual SSD to the original "new" state or as close to it as possible. Thank yoo! E71
  20. The Samsung SSD 850 PRO gives enthusiasts about everything they could want in a single SATA SSD. Like drives before it, Samsung has infused the SSD 850 PRO with new technology to make it a class leader in terms of performance, endurance and warranty. Samsung SSD 850 PRO Review
  21. I've got a Samsung 850 EVO SSD (500G) on a windows 10 system. SSD is connected as non-boot drive for now Firmware is EMT01B6Q and Samsung Magician (4.9) fails when I try to update to EMT02B6Q. I've tried the Samsung Magician Secure Erase and it still fails. Is there another way to update the firmware, perhaps DOS based, like the Secure Erase? If I don't update will this cause problems with Windows 10?
  22. Hi, I have a spare Samsung EVO 840 500 GB SATA III SSD. I'd like to buy another - Samsung EVO 850 then - and stripe them to a performant RAID 0 array. I expect around ~600 MB/s from a Thunderbolt 2 enclosure. Hower I only can find one that you can buy empty: The AKiTiO Thunder2 Duo Pro Are there alternatives? As I don't know the brand and the design of it. Thanks!

  24. The prices of older SATA SSD have really gone down now. I have a RAID-1 of 2x 3TB HDDs as scratch storage for Steam games, mp3s, ripped movies etc I am not even getting close to 1TB - lot's of games installed that I haven't played for a couple of years so I could go even lower, but 1TB is a convenient size where I won't have to worry about what to keep. I am really tempted to get 2 x 'cheap' 500GB drives and RAID-0 them. Currently 2 480/500/512GB drives are actually cheaper than a single 1TB one and you get better performance (and way better than HDDs) I'm not too worried about losing data as I can re download most of the data and for the rest it is backed up in 3 other places. Altogether it seem like a no-brainer to go ahead and do it. Any downsides to this? Obviously with m2 SSD already available this is not very future proof, but to get advantage of m2, I would need to change the motherboard and the CPU etc so not really feasible.
  25. hi i really like this forum and i read many review about ssd i would like if storage review is willing to make some reliability test about ssds there are so many tests around , some put the samsung ssd at the top , another the intel someone makes a huge different between MLC SSD and TLC NAND thanks cheers sorry for my poor english
