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.

It seems i have the same problem on a seven days old 120GB SSD

This is from a friend of mine. It is clear that it is a general problem.

A ratio of 2-to-1 in NAND-to-Host writes you show in the pictures is not unusual and it is not too bad.

[AMusa2]

I agree, 2-to-1 is OK, but as you can see in the print screen below taken a few seconds ago it keep growing. And as you can see in my friend print screen above the ratio in 4-to-1. I don't think it's OK. And from what i have seen over my research on model 520 that ratio is below 1. So, in my opinion is something wrong here . But I'm no expert and i might be wrong, that's why i am asking here.

Thanks for your support!

Mine is even worse!

Windows 7 operating system.

ASUS G73SW Notebook

Current Status on drive:

(1) INTEL SSDSC2BW240A4

Several days ago as posted above:

Power On Hours : 250 hours

Power On Count : 98 count

Host Reads : 2127 GB

Host Writes : 642 GB

NAND Writes : 2856 GB

Today:

Power On Hours : 302 hours

Power On Count : 111 count

Host Reads : 2535 GB

Host Writes : 671 GB

NAND Writes : 3081 GB

The write amplification is increasing. now up to 4.59 ratio.

I moved the temp files and internet files to the second drive, do not use drive compression or encryption.

Normal use on a daily basis. do not download movies or photos.

I also installed the same drive as a second drive in my system for file downloads and backups and this is how it looks:

Power On Hours : 117 hours

Power On Count : 34 count

Host Reads : 324 GB

Host Writes : 247 GB

NAND Writes : 236 GB

The write amplification is a 0.95 ratio.
