If not aligned, WRITEs are a problem - a write can cause two SSD blocks to need to be updated, which is an unnecessary update to a flash memory block. Life-1 for no reason - a write update to two blocks is going to take more time than a write to one block So, testing read speeds is going to show either of these things how, exactly? You might find this thread helpful in response to Fred's comments: »windowssecrets.com/forums/showth···e-drives Frankly, it seems to be, for most people, searching after the Holy Grail.

JohnInSJ Premium join:2003-09-22 San Jose, CA Reviews: ·PHONE POWER ·Comcast	The linked comments say exactly what I said, with more words Write is the issue, not read. Slight but possibly insignificant in modern SSD increase in wear. Two read/writes vs 1... two REALLY FAST R/Ws, but still, double the time. For Writes. Sometimes. So Fred tested the wrong thing (read speed) -- My place : »www.schettino.us

Vchat20 Landing is the REAL challenge Premium join:2003-09-16 Columbus, OH	reply to trparky said by trparky: So do I even need a page file for a system that has 8 or 12 GBs of RAM? 7 will pretty much handle this stuff automatically such as disabling automatic defrag on the disk, disabling superfetch, and other system services unnecessary on an ssd. Just do a fresh install on the drive without going outside of 7's guided install process and do the prior mentioned pagefile and hibernation tweaks and you'll be fine.

dave Premium,MVM join:2000-05-04 not in ohio kudos:8 1 edit	reply to DKS It so happens that I often chat to a senior guy where I work whose job in part involves figuring out the impact of various disk technologies on our product line. And he tells me it does make a difference. Unfortunately his reports aren't public. Misalignment is mostly a write problem, and more so on a not-new drive. (You can't overwrite an SSD block; the controller needs to allocate an erased block, and schedule the old one for erasure.) FWIW, not all SSDs are equal. Different controllers choose to optimize for (note rare example of correct usage of the word) different scenarios.

OK, but what if I'm restoring an image of Win7 (originating from mechanical HDD) to SSD? What other tweaks I need to make beside the following: - drive alignment (if I want that extra non-perceptible boost in performance) - disable superfetch, defrag, indexing - move page file away - TRIM (does win7 automatically enable it if it detects itself sitting on a SSD?)

Depends what you're doing with it. I run 16GB with no pagefile, but I'm gonna have to turn that puppy back on when I start running my VMs again. If you're just surfing the web and checking your email, you're probably good without a pagefile even at 4GB. Turn off hibernation, set the pagefile initial size to 0, max size to whatever (usually equal to the amount of RAM you have is a good policy, double your RAM if you have 4GB or less) and Windows won't page out unless it absolutely needs to. Disabling the pagefile altogether means a crash if you fill your RAM, setting it to a 0 initial size means it won't be used unless your RAM is literally full; giving it a nonzero initial size means Windows will page out enough data to fill that initial size as soon as there's enough disk idle time for it to do so without impacting performance. It does this and marks the paged out portion of RAM as disposable, so it knows it can just free that RAM without having to page it our first (since it's already written to disk), but if you never actually fill your RAM, you're using erase-write cycles on your SSD needlessly.

There's no alignment issue with Windows 7 - it knows how to do the alignment. Previous versions of Windows did not; so those are the systems on which you need to fix the alignment (if you care). That includes the update from not-Win7 to Win7 case, of course.

trparky Apple... YUM Premium,MVM join:2000-05-24 Cleveland, OH kudos:2 Reviews: ·Time Warner Cable	reply to trparky Why I ask all of these questions is because my system is acting really weird as of late. As you might know, a system with an SSD should simply fly. Right? Click on an icon to launch a program and it should have it loaded... like yesterday. But I'm seeing some huge issues with my system here. When I boot my system it's fast. Everything seems fast. Use the computer for some time, say like for six hours, and you can see the system gradually get slower. Programs take longer to launch, right-click gets slower, etc. Hell, even the mouse starts to seem like it's asleep at the wheel in the sense that if you move the mouse the cursor doesn't always respond. I have no idea why this is so. I can't pinpoint where the problem is. I've been doing troubleshooting for almost two weeks now and have come up completely empty-handed. A system with a Core i7, 12 GBs of RAM, and an Intel 520 Series 240 GB SSD should not be having these issues. -- Tom Boycott AT&T uVerse! \| Tom's Android Blog \| AOKP (The Android Open Kang Project)

Doesn't sound like any sort of a disk issue. I'd look at CPU load, particularly for interrupt and DPCs (use Performance Monitor.

trparky Apple... YUM Premium,MVM join:2000-05-24 Cleveland, OH kudos:2 Reviews: ·Time Warner Cable	Yeah, I've looked at that too. Very low CPU usage, most of the time it's less than 25% usage across all eight "CPUs". I know that this machine has DPC Latency issues and I have another thread open in this same forums regarding the issue. »[WIN7] High DPC Latency with High Network Traffic But now it seems like it doesn't even need network traffic to have DPC Latency shoot through the roof. NDIS, TCP/IP, and some driver for the nVidia video card seems to be the biggest culprits according to LatencyMon. But, after looking at the other machines in my house with LatencyMon they too have the same latency spikes but they don't seem to be having the same issues that this desktop has. I'm at a complete loss as to what could be causing these issues. Like I said, I've been troubleshooting this issue for almost two weeks now and I'm no closer to a solution or a reason why this is happening than I was when I started investigating this mess. Could I be looking at potential hardware failure here? Motherboard? CPU? -- Tom Boycott AT&T uVerse! \| Tom's Android Blog \| AOKP (The Android Open Kang Project)

trparky Apple... YUM Premium,MVM join:2000-05-24 Cleveland, OH kudos:2 Reviews: ·Time Warner Cable	The processing latency issue comes and goes. I can't seem to find a connection between the issues. As of right now, Interrupts per Second according to Performance Monitor is nearly 10 Million but it's not effecting the performance of the machine. It's as fast as it should be. It could be fine for several hours and then suddenly start running horribly.

dave Premium,MVM join:2000-05-04 not in ohio kudos:8	10 million interrupts per second seems like a hell of a lot. If it takes of the order of a few hundred instructions to service an interrupt, that's more than one CPU core's worth. Are you sure you read that right? My admittedly fairly idle system is taking around 6 or 7 hundred interrupts/sec.

Octavean Premium,MVM join:2001-03-31 New York, NY kudos:1	reply to trparky I have a number of different SSD models of different capacities. A number of them are of OCZ make. One of my oldest SSD models is an OCZ Agility 60GB (v1). The system it was installed in recently started to freeze randomly. I've never had a problem with any SSD but I figured my number was up so I replaced it with a standard 500GB HDD and restored a backup from my Server. A quick and easy solution I thought. Long story short,.... It still freezes without the SSD and I no longer suspect the SSD is defective. So I'll try a fresh install to see if I can nail down this problem.
