SSD Thread (Benchmarks, Brands, News, and Advice)

You have posted several different "correspondences with Samsung", like the one that said there would be TRIM support FW flasher by the end of November... It is the end of November and still no flasher.

I dont know, its samsungs problem

s**t that sucks. i must have misread something. i thought my version did, and i was waiting for TRIM.

Post an HD Tune benchmark, that can tell us if it has GC and is working. Some Summit users(PB22-J)have reported getting GC to work by leaving their PC's on at the BIOS screen, 10-20 minutes should be sufficient with HDtune before and after benchmark to tell if it is working) doesn't work on mine--only S1 sleep mode.

HD Tune will show a flatlined 150 mb/s or so graph on a degraded drive that the controller doesn't see the free space the OS is showing. If GC is working the graph will jump to +200 mb/s at the free space areas.

I remember reading somewhere, can't remember where and it was a long time ago that if I delete all partitions and format, my speeds would lessen. Is that true or did I misread?

tissot,

you may be remembering one of my posts (which I can't find for the life of me now) where I was helping someone clean install an Intel G2 with the new firmware (TRIM enabled)?

The important part of that post was that under an O/S that supports TRIM, like Win 7; you should first format the drive then delete the partitions so that the drive is 'clean' again for a fresh install at full drive speed. If you simply delete the partition first, then the O/S doesn't send the TRIM command and the drive is 'dirty' and 'used' and will not perform to spec's, even with a clean install.

for additional information.

Was this what you were thinking of?

the moment the new partition then gets written to, it gets cleared. if i got that right, it all doesn't matter. it just means the moment of sending trim is later than expected: first time the partition gets written to.

[tilleroftheearth]

davepermen, No.

There is a distinction here as the link I provided proves.

[davepermen]

Windows 7 using TRIM?
File Delete: Yes
Partition Format: Yes
Partition Delete: No


all that says is, it doesn't happen when you DELETE the partition. every partition you want to put to USE, you have to FORMAT afterwards. and THEN, it happens.

laptopgun, yes, looks fine the way it is.

Thanks. I figured as much, but wanted to be sure given I'm a Thinkpad user and not exactly a pro at installing hardware and clean installing OS's. Yeah I know it was the T/X 61 and earlier that were limited to SATA 1 speeds. Still paranoid.

The results are fine. You can compare it with mine here. As you can see I got some speed up after installing new Intel drivers...

Good. That's the name of the RAID version of Intel Storage Manager right? No RAID for me but I'll take it under advisement. I'm waiting on the TRIM FW and i'll upgrade to W7.

I have to ask again though (I got no answer). Is it correct to say the Intel Storage Manager didn't support Trim so I have to use Windows built in SATA driver if I want Trim. When the time (fixed firmware, ponied the $ up for W7)comes, of course.

[davepermen]

the new drivers are not just for raid, they are for everything. and can boost the performance quite a bit.

davepermen,

The distinction is that if you are simply deleting partitions and re-installing the O/S (even Win 7), then you are beginning life with a compromised SSD (performance-wise). It may eventually all get cleaned up after a (long?) while of using it under a TRIM aware O/S, but why would you not want the maximum speed right from the beginning?

+1

The new Intel Rapid Storage Technology drivers have increased the 'snap' factor of both my non-SSD based and non-RAID systems.

On my desktop VRaptor/3xRaptor +4TB data drive configuration they have 'civilized' the Raptors - yes they are actually quieter. (I'm guessing a better optimized NCQ algorithm?). These benefits are for both Win 7 x64 and Vista x64 installations.
