Windows update killed my write speeds?

[deff]

Comp specs are in my sig.

I've spent the last couple of days fiddling with my M28 trying to get it back to factory speeds (its been operating in a laptop for the past couple of months). Did a secure erase, installed Win7 and everything was operating fine: 220MB/s read and 180MB/s write.

Well, I finished installing drivers and all the updates, reran CrystalDisk for shits and giggles, and to my surprise, my writes dropped all the way down to 60MB/s (!!!). Read speeds and access times haven't changed, just the write speeds.

Did Windows Update just tank my write performance? I ran ATTO just to verify and sure enough, its 60MB/s.

Any tips on to what the hell just happened?

Did the updates include any driver updates? I've seen a lot of driver updates that will result in decreased performance or reduced functionality. Double check the history of the updates, I haven't seen anything that would do such a thing, but maybe it's an update bug.

Double checked the update history, nothing but security and hot fixes.

Did a Google search and it seems I'm the only person. I guess I'm left with going to through drivers one by one

You use Patriot Torqx M28 64GB?

Can you show us CrystalDiskMark + AS SSD screenshot?

220MB/s read and 180MB/s write

.
Isn't that supposed to be 140MB/s write?

Just curious, what were your speeds immediately before running HDDErase?

Edit, the link in your sig for your drive is 115MB/s write.

Ill post caps from Crystal and Atto later, at work now.

Before the secure erase they were around 70MB/30MB read/write. The drive was running in a 5year old laptop for about 4 months.

Seems about right.

These are your drive's origional specs.....

Sequential Access - Read:up to 260MB/s
Sequential Access - Write:up to 115MB/s

That's a best case/out of the box stats.

My vote is that your drive is doing all it can do and has no problems.

BTW.....Those sequential speeds have little relevance to the actual desktop experience of an SSD drive. Look for 4K or 4K-64Thrd specs on the ASSsd program for a true measure of your SSD's desktop performance.

Here's my AS SSD bench:

Here's my AS SSD bench:

Pretty slow.

If I were you I'd quit benchmarking the thing and let it sit idle after clearing the Recycle Bin.

Leave it sit for a coupla hours to let garbage collection or TRIM do it's job.

Got the latest Intel drivers? Enable write caching?

Latest drivers installed and caching was enabled. I also let the drive idle all night, but I'm not sure if the VBM19C1Q firmware update disabled GC when they added TRIM support.

I'm tempted to get a SandForce-based boot drive, but would it be worth it seeing how my read speeds aren't that bad?

AKAIK nothing will disable GC.

I dunno what to tell ya. It's the write speeds that bother me.

If you're looking for another drive those little Crucial 64GBs seems to be on sale right now.

I don't like the SF drives.
