  1. Hi, Copying 15GB of files - as an example - (few and large not many and small) from my C drive which is on a sata adata 128GB ssd (rated at 500MB/s reads) to my G drive with is on an intel nvme pcie ssd rated at 1800/1800 R/W is unbeliveably slow. bursts at 200MB/s settles at 47MB/s ... I'm at a loss for words. The drives are new. they perform as expected under crystaldiskmark/atto benchmarks. My pc specs : windows 10 64bit, ryzen 7 2700x, rtx 2080, asrock x470 taichi, all updates, latest drivers etc. i assembled the rig myself, installed the os everything myself. did not expect this at all. Source SSD: Adata SP900 128Gb sata3 ssd Destionation SSD: Intel ntel 660p NVMe PCIe M.2 1TB Motherboard has latest bios from asrock page. I did not do anything io intensive in the background, the system is not malware infected, i keep things nice and tidy both hardware and software wise. What in the world is going on ?

    Benchmark SSD

    Hi Friends, I have Samsung SSD PM1633 , I use them in RAID 10 with 12 SSDs with Hardware RAID, i run FIO on it, with below option: direct=1, iodepth=32, numjobs=8 , bs=8k, runtime=180, rw=randrw, rwmixread=70, ioengine=libaio, I use fio as directly on the server , output : IOPS Read : 90.3k IOPS write: 38.7k Latency Read: 2059 u Latency Read: 1807 u my question is: 1. do really I get IOPS Disks? 2. do this IOPS with this latency is real? as mentioned , this results are as local, 3. but test remote with FC to host show low iops, what is reason? very Thanks,
  4. Hello everyone, Ok so basically i have a 50$ AUD budget on improving my laptop's performance, i own a Dell Inspiron 15 5576 Gaming Laptop AMD Version with an AMD A10 9630P and RX 460. and it only has a normal mechanical 1TB HDD 5400 RPM Drive and i want to improve performance. I did consider a 1TB SSHD but they are at cheapest 89$ in AU An M.2 SSD 128GB goes for 49$ An intel optane 16GB is 30$ From research, it's AMD so i cant use intel SRT or intel RST to improve performance on my storage devices, i also looked into Dataplex which got sold to samsung but was popular so thats not a solution This plan would involve buying an M.2 SSD Drive 128GB or 64GB on the cheap and using software to make it a cache drive, and as i said above, dataplex and intel SRT arent an option and AMD have something similar but its only for ryzen located here the only one i found was But i have not seen any video's or any performance benchmarks showing that fancy cache even works. So thats the options that i have found ( please correct me if im wrong ) for SSD Caching with and M.2 SSD Drive and software solutions The other option is Intel optane 16GB M.2 SSD Slot version I did alot of reading and reviews which stated that intel optane does not work on AMD and only worked on intel platforms, but this was all from 2016, it seems their was an update in which intel allowed them to work on any M.2 NVMe slot, but i havnt seen any videos or proof, just articles So i need some advice, Should i go with M.2 SSD + HDD + Software ( unsure of what software yet, please advise ) Or buy an intel optane and try my luck
  5. Hi Everyone! I intend to buy a new SSD Drive for my MSI GE60 Laptop. I know that data transfer speeds are much greater than Mechanical drives, however, I’m not really sure when it comes to comparing between SSD Drives, as the same manufacturers have diferent specifications for drives with the same storage space. For now I don’t need space, I only need performance and, of course, reliability. I want to buy from any Portuguese store (i'm living in Portugal right now) because of any RMA issues that might come up. I’m inclined to buy a Kingston Drive (is the only brand I know). Can you guys help me choose the best 120Gb SSD drive from here? I’ve already sorted the results in the link I leave below. Feel free to ask any question or make any suggestions! Thank you!

  6. Hi to all, ask some advice for my question and hope it can be solved. It makes me so anxious all day because I I have severe OCD. I am currently working on interacting with SSD memory through a FPGA using SATA protocol. I am using a Xilinx KC705 evaluation board and SSD is from Samsung. I have connected the SSD device to the KC705 board through a FMC connector. I have used Xilinx 7 Series GTX for the PHY layer. I am trying to work on the initialization part of the SATA protocol and that's where I am facing issues. I have been able to do the OOB initialization with the SSD device. After that I have been able to negotiate the speed between host(FPGA) and device(SSD05) at SATA II based on recognition of ALIGNp at the line rate specified. I am stuck at the "IDLE" state of the link layer state machine. As per the SATA spec, the device link layer transmits SYNCp continuously to the host in IDLE state. What I am getting is that, I receive SYNCp for some period then I stop receiving as shown in Figure 1. Afterwards, I receive ALIGNp and SYNCp in random numbers as shown in Figure 2. I have captured the waveforms on chipscope. Description of the signals captured on Chipscope :- "currPrimitive" - The primitive that host link layer is sending presently. "currState" - State of my state machine (not relevant) "rxelecidle" - A value '0' denotes that the OOb initialization has been completed and the device is sending primitives. "prim_align_det" - ALIGNp primitives obtained from device. "prim_syn_det" - Syncp primitives obtained from device Observations :- As it can be seen in figure 1, I receive ALIGNp from device and after receiveing 100 ALIGNp, my link layer starts sending SYNCp. The device then starts sending SYNCp but after few numbers it stops and then in figure 2 you can see that the ALIGNp and SYNCp are received randomly, This behavior is confusing. Hence my question is what could be the possible reasons for such behavior of the device. Here are few of my ideas :- 1) "Maybe the device lost synchronization with the host" - But how is this possible. After I receive around 100 ALIGNp(I have chosen to count upto 100 ALIGNp continuously for deciding on that the rx data is aligned), Host link layer sends ALIGNp untill it recognizes 100 SYNCp continuously from device. So I am assuming that My host is sending enough ALIGNp for the device PHY layer to synchronize (because the device itself is sending SYNCp at the hand-shaken line rate). 2) As per the SATA spec, after every 256 Dwords, two ALignp need to be send. I have a section of code that does the job. It counts and sends 2 ALIGNp. That is for every 256 Dwords, 254 are non-ALIGNp and 2 are ALIGNp. This is done while my link layer is in state "9" i.e. sending SYNCp. So, this should also not be an issue(maybe, not sure). 3) I have checked that the reference clock to my GTX is stable and similar to what I selected during IPcore generation. I can't think of any other issues which might cause such behavior. Please share your views on what might be the possibilities. Also you can share your own experiences of SATA device behavior in it's idle state. Thanks all.
  7. Regardless of this sub-par performance, the TR200 will certainly offer significantly faster boot-ups and overall responsiveness compared to platter-based systems. Toshiba stresses this fact. However, other budget drives like BX300 outperformed the TR200 in every category--sometimes by a significant margin--all the while featuring an identical price tag. This puts the new Toshiba drive in a tough spot, as it is difficult to recommend as a result. Because the budget SSD market is filled with so many viable options, drives of this class really need to stand out in some way. And though the TR200 does offer better power efficiency than most (i.e. an average of 1.6W during operation activity for the 960GB model), we’re just not sure that’s enough to warrant a purchase until this drive is priced more aggressively than its competitors.

Though the drive is currently only available in a 512GB, 2.5” form factor, Intel states that it will be releasing more capacity, ranging from 128GB to 2TB, as well as a M.2 form factor version. The drive is being marketed as an HDD replacement and has a MSRP of $179 for 512GB. Intel 545S SSD Review
  13. 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.

  16. 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

    Anyone tried this product?

    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.
  18. 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.
  19. 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
  20. 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
  21. 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.

  25. 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!
