" rel="nofollow - Issue: unstable & poor writing speed, spikes from 200MB/s to 9MB/s, file size bigger than 4GB Is there any particular setting and/or requirement to maximize the performance of Intel 600P? I do understand that 600P has lower performance than M8PeG, which is fine with me. M8PeG spikes very little within acceptable speed range and I did not have any issue with Plextor at all. but 600P does spike too much. Used same system OS and BIOS settings; MB: Z97 Extream9 BIOS: 2.00 7/20/2016 OS: Windows 10 Pro V.1607 OS Build 14393.321 (fresh installed each time)

Is your 600p in the Ultra M.2 port? The other M.2 port is a PCIe 2.0 x2 interface. When you say the "file" is larger than 4GB, do you mean a single file, not a folder, is 4GB or larger? Have you monitored the temperature of your 600p? It is possible depending upon the environment the 600p is in (covered by a video card, no air circulation) that it is throttling due to over heating. This is a common problem with M.2 SSDs. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - Yes, it is in the Ultra M.2 port. Single file larger than 4GB. Temperature should be ok, no video card, case opened. Any suggestion?

Please explain the copying of these greater than 4GB files. What is the type of the file? You are copying these files to the 600P, but what is the source of the 4GB+ file? The source device of the 4GB+ file? Does the 600p serve any other function in the PC? Just a data drive? How much free space is available? You could try enabling Write Caching in the Device Manager entry for the 600p, although it is likely enabled now when using the Windows 10 NVMe driver. Worth checking regardless. Nothing in the UEFI/BIOS to configure. You could check the PCI Express Link State Power Management setting in your Windows Power Plan, and set it to Off. The temperature which "should be Ok", remains unverified. If the performance starts out good, but drops off after a minute or so and stays that way, then you may be experiencing over-temperature throttling. M.2 SSDs tend to suffer from this, as they have no heat sink on the SSD controller chip at all, unlike a 2.5" SSD whose metal case acts as a heat sink. I haven't copied large amounts of data to my 600p, which is the 512GB model. It's the OS drive for a DeskMini 110W PC. I have read about situations where the Windows NVMe driver will cause poor write performance with M.2 SSDs. That is inconsistent, some people get it, others don't. Try running a benchmark test like AS SSD or CrystalDiskMark to check the write speeds. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

File type: an ISO file, which is a Windows 10 CB image single partitioned 600P: C:/ OS only (Windows 10) Windows Desktop: single 4GB file (ISO, Windows10) + rest(free space) Performed 'Desktop to Desktop copy' (see attached) Write Caching: tested both On & Off> no difference PCI Express Link State Power Management setting : OFF Temperature "should be OK' : Power On>Window Start> Copy & Paste Tested three different 600P 128G and same results. Additional information: Installed OS is Windows 10 Pro 1607, OS Build 14393.321 and 600P is using the native NVMe driver, 10.0.14393.0, 6/21/2006 600P 128G: writing speed spikes from 9MB/s to 110MB/s  Plextor M8PeG 256G: constant writing speed around 417MB/s  |
