Intel SSD 530 NAND Write Problem

[fZhan14]

Hello, everyone:

I bought an Intel SSD 530 120G for my laptop several days ago. It worked well with the OS Win8.1 Pro x64.

When I paid attention to the NAND writes, something make me confused.

The situation is as follow:

The SSD with the OS is the first(primary) Disk, and the HDD is the second one. I have moved the cache of IE, chrome and Firefox to the Hard Drive using IE setting or mklink command, and verified it correctly. With the explorer working, the written data stream from cache is produced in the HDD partition theoretically, also I have got this conclusion through the System's Resource Monitor and the Diskmon from Microsoft website. When I cached several Movies embedded in any explorer without other operation separately, there are lots of written data traffic produced in the HDD partition, and just little data wrote in system disk(SSD), it's no doubt. Finally, each test(using one kind of explorer) improved less than 200Mb in Total Host Writes which is normal for system operating, but this process also consumed about 3Gb SSD's Total NAND writes in total in the CrystalDiskInfo 6.0.1. Also I have got the same result with the newly Intel SSD Toolbox, AIDA64 3.20 and CrystalDiskInfo 6.0.1. In fact, this written data traffic produced by explorer's cache in HDD is calculated into the SSD's total NAND writes.

Actually I'm not care of the SSD's wear, and I'm sure it couldn't reach the limited lifespan with normal usage until next generation product arrives. This accidental discovery confused me now, and the result above make me suspect the theory, Putting IE/Chrome or System cache into other medium/drive saving your SSD's wear.

Q:Here, I want to know what makes this strange condition happen, the drivers, system's bug, bad support for old mainboard, the system's setting&config or the special system log?

Testing condition:

Thinkpad R400(GM45 motherboard)/P8700/8Gb RAM/Intel 530 SSD+Hitachi 7k500/Intel 5300 AGN/Win 8.1 Pro X64 with the Win 8.1's Default config and drivers, except trunning the service Superfetch off mannually.

I could make sure the location of explorer cache(IE, Chrome, Firefox) in HDD, also the written data traffic in HDD, and the vast imprived NAND writes in SSD simultaneously.

Thanks for your help.

Hi, Gklin:

Could you please using SSD Toolbox to export more details of your 535 SSD? And also let us know what's the software/hardware configuration, and usage model (workload).

even do nothing, the 535 still write something to the nand. about 15G+ every hour( 480G, maybe less on 240G).

Hello,

We would like to confirm that this has been reproduced in the labs and our engineers are looking into it. We are working to determine the effects this may have and any additional recommendations about this condition.

It seems os x and linux has not this issue, only windows has this issue. So it may be the windows driver enabled some feature and caused this issue.

Hi Yanqiang,

The device is running on windows server 2012R2 in Hyper-V.

MSSQL server , very light loading.
