    Benchmark of eleven Seagate ST4000VN000 4TB NAS drives

    I previously posted a set of tests like this on the Seagate ST2000DL003 four years ago. It was finally time to create a new RAID volume, and I decided on the Seagate ST4000VN000 for my next array. In HD Tune Pro, there are six levels of test speed/accuracy: Partial test (five levels ranging...

    Seagate Green 2TB ST2000DL003 sample variation

    Oops, looks like I forgot to follow-up on this by posting the test results of all twelve drives together. As it turned out the next seven drives didn't follow the pattern of average transfer rating sorting the same as serial number (it would have been enormously surprising if they had)...

    Glossy HP zr2740w How-To (AG Removal)

    Firstly, you'd need a lacquer that matches the AG's index of refraction when hardened. Secondly, the lacquer (or pretty much any spray coating) is going to almost certainly be quite vulnerable to scratches, and over time the scratches will build up. (Tape, and any plastic that is not...

    Glossy HP zr2740w How-To (AG Removal)

    Why not get a sheet of HEA2000K-clear to cover the screen after AG removal? Sure, it'll still be glossy, but the reflections will be much darker and the polarizer will be protected.

    Dissatisfied with HD 6950 quirks... should I go with GTX 570 for 2560x1600?

    Oooops :o Now that you mention it, I remember making that adjustment a long time ago, but I'd forgotten that it was specific to each individual forum. Hmmm, interesting. I might be preaching to the choir, but I like to use a CRT side-by-side with an LCD because the CRT can do things no LCD...

    Dissatisfied with HD 6950 quirks... should I go with GTX 570 for 2560x1600?

    Bump. I don't know why the main Video Card forum doesn't allow you to look more than 1 page into the past. Makes no sense. I'll be receiving my RMA-replacement GeForce 8800 GTS 512 tomorrow, and that will free me up to get rid of my Radeon HD 9650. I'd really appreciate it if someone would...

    Dissatisfied with HD 6950 quirks... should I go with GTX 570 for 2560x1600?

    jeremyshaw, could you try disabling color management, or using a photo viewer that does not do color management? You an also test if color management is being done: Take a screenshot of the gradient being viewed, and compare the screenshot against the original gradient. If they're different...

    Dissatisfied with HD 6950 quirks... should I go with GTX 570 for 2560x1600?

    Low-resolution modes after boot-up are not a problem, because I can disable GPU scaling. If I leave it enabled, low-resolution modes (in old or retro games) are resampled with the same ugly scaling, first smoothly to 1280x800 and then pixelatedly to 2560x1600. I'm annoyed at having my bootup...

    Dissatisfied with HD 6950 quirks... should I go with GTX 570 for 2560x1600?

    My GeForce 8800 GTS 512 finally kicked the bucket, and while I am in the process of RMA'ing it, it's a good time to upgrade; I upgraded the rest of my system already, to Sandy Bridge. My last 3 video cards were all NVIDIA (GeForce2 MX, GeForce 6600 GT, GeForce 8800 GTS 512), but this time I...

    Areca 1261mL PCIE 8x in a PCIE 4x lane?

    I don't know enough about PCIe to know how gracefully it handles this situation, but I can say this: I have my ARC-1261ML in a 8x PCIE slot, and it only goes up to about 840 MB/s. Areca's published benchmarks show the same limit. Even in PCIE v1.0, each lane is 250 MB/s. So 4x should give...

    This is what AG coating does to LCDs (magnified)

    Yes Snowdog, you're right, it's my pet theory and I have very little evidence for it. The ultimate experiment would be to do an AG coating transplant between two LCDs. Is it possible to put an AG coating back onto a monitor after it has been removed using the wet-paper-towel-soaking method?

    This is what AG coating does to LCDs (magnified)

    Obviously I did not make my explanation detailed enough. These effects are multiplicative, not additive! If you multiply something by zero you get zero. If the AG layer had zero thickness and were directly laid on top of the pixel layer (which is impossible because you need polarization, etc. in...

    This is what AG coating does to LCDs (magnified)

    AG coating "aggressiveness" or "harshness" is not at all the only thing that controls how much sparkle effect there will be. There are many factors: 1. Pixel size (smaller pixels = more sparkle) 2. Amount of black space between subpixels (more black space = more sparkle) 3. Distance between...

    Alternative to Robocopy

    While Robocopy does defragment files as it copies them, it does not defragment directories. In fact directories end up being very, very fragmented in the copy. Most file-level copying utilities probably have the same flaw. (It'd be pretty easy to get around this problem using temporary...

    Seagate Green 2TB ST2000DL003 sample variation

    Cool, nice to know I'm speaking to a fellow programmer. Do you mean Linux, or some other flavor of Unix? As for me, my research into hard drive internals began when an IBM "Deathstar" I bought in 2001 developed a huge batch of bad sectors 1 year later. I wrote various small programs to assess...

    Seagate Green 2TB ST2000DL003 sample variation

    I really wouldn't be surprised if all manufacturers' green drives were like this. I've seen more variation among Western Digital WD15EADS, and among WD20EADS, than among these Seagates. As you said, I would like there to be less variation. It seems to me that the faster drives might get...

    Seagate Green 2TB ST2000DL003 sample variation

    I just bought five ST2000DL003 with the intention of using them in a RAID array. Because I'm using an Areca ARC-1261ML which can do sustained sequential transfers up to 840 MB/s (maybe even faster — I haven't yet had the opportunity to max it out), the slowest drive among these is going to...

    S23A550H 0ms input lag!!! Woooo

    I suspect that many or even most measurements of >1 ms of input lag are misinterpreting response time as input lag. Instead of measuring when the faintest image starts to appear, they only count a somewhat strong image as input response — and there lies far too much subjectivity. Using...

    H-IPS vs S-IPS

    Nashbirne, nice work photographing that H-IPS panel! I wouldn't have thought the 18-55mm IS would do so well reversed (that's the kit lens you used, right?). Did you use a reversal adapter or something jerry-rigged? jangaboo, that LG 37LH30 has a much bigger fill factor than my Dell...

    Looking for a CRT monitor

    Cyberbeing, thanks, that is quite interesting. What makes you say the F520 has tinted glass? This wouldn't make much sense, as it would tint the output from the phosphors, darkening the overall output. My theory is that the aperture grille is matte black in the FW900, and shiny black in the...

    Looking for a CRT monitor

    Well that might be subjective, but I like an aperture grille much better. A shadow mask's image looks more fuzzy to me and less aesthetic. The only downside of an aperture grille is that there will be one or two very very thin "damper wires" (much thinner than a pixel row even at the maximum...

    Looking for a CRT monitor

    Out of those options, going by the specs alone, I would go with the Dell P992. It has the best maximum horizontal sync frequency (meaning it'll have the highest maximum resolution at any given vertical refresh rate), and uses an aperture grille. The Dell P992 will be able to do 1344x1008 at...

    Looking for a CRT monitor

    Note to anyone considering getting GDM-F500/F500R/F520... I've only seen (and owned) a GDM-F500, but the F500R seems to be almost identical except having extra stuff (sRGB mode, 170 Hz instead of just 160 Hz). The GDM-F520, however, seems to be more like the GDM-FW900, in that it probably...

    Looking for a CRT monitor

    If you don't like widescreen and prefer 4:3 then the Sony GDM-F500 (or GDM-F500R) would be better. It has a true constant 0.22 mm grille pitch, as opposed to the GDM-FW900 which has a 0.238 to 0.277 mm variable grille pitch (not even 0.23 to 0.27 as the specs claim). The GDM-F500 can do a very...

    Retrofit a 30" LCD, changing it from matte to glossy?

    The 1.5200 turned out to reduce noise better than anything else so far: 19.2% (at 43°C) with the MXA film over it. This suggests the index I'm trying to match is a bit closer to 1.513 than to 1.515. Next I'll try a 1.521 mixture, and see if that works even better. It looks like Cargille Laser...

    When will we see 3840*2160 monitors?

    I would love to have a 3840x2160 monitor. The reason I got a 30" 2560x1600 was primarily for photo viewing, but that's still barely adequate for viewing 5184x3456 photos in anything approaching their full glory. Does this system have two 3840x2160 panels or two 1920x2160 panels? Does every...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Looks like that doesn't have an anti-reflective coating. The description doesn't say anything about having an AR coating, and the customer review complains about its reflections.

    Retrofit a 30" LCD, changing it from matte to glossy?

    After 8 days, MXA + 1.5220 Refractive Index Liquid reduces noise to 28.8%. It was reducing it to 20.7% the same day it was applied, so it's now 28% worse... which is still just as good as Scotch Packaging Tape (and slightly better than freshly applied MXA + immersion oil). I wish I knew...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Your sample is actively leaking oil, even after you cleaned it away from the edges? Does the sample slide when you touch it? For me, with Type A Immersion Oil, leaking only happened with sliding, and the sliding stopped after one or two days. With Refractive Index Liquid there was no sliding...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Nurf, did you make any progress with the Type B immersion oil? I finally did another measurement, and 20 days after being applied, the MXA + immersion oil is reducing noise to 35.5%, which means there's no significant difference from how it was after 7 days. But subjectively I can see a tiny...

    Retrofit a 30" LCD, changing it from matte to glossy?

    I don't understand your comment about the paper towel. Removing the AG coating involves soaking the LCD with paper towels wet with distilled water, for many hours, then removing the paper towels and pealing off the AG coating. What did you accomplish by "cleaning" the LCD with your "rough...

    Retrofit a 30" LCD, changing it from matte to glossy?

    neks0ne, that looks awesome, great work! But I think you left out some details. Just putting glass in front of the LCD wouldn't get rid of the sparkle from the AG coating. So, before doing this, did you remove the AG coating (e.g. using the wet paper towel process)? Were you able to make the...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Nurf, I had an easy time getting the air bubbles out both with and without oil. I had no oil bubbles, just air bubbles. 1. I cleaned the MXA film with soapy water and a light touch, then rinsing with water. 2. I cleaned the area of the LCD I would be working on and made sure there was as...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Well, after sitting for 7 days, the MXA + immersion oil is reducing noise to 36.1%, compared to 30.3% after just 1 day. So basically it got 16% worse after sitting for 6 extra days. Subjectively it still looks good. I think the oil will probably need to be periodically renewed or changed, maybe...

    Retrofit a 30" LCD, changing it from matte to glossy?

    I got my immersion oil on Monday. Still have more experiments to do, but what I can say at this point is: Photodon MXA film + Cargille Type A Immersion Oil reduces the grain noise in my LCD to 30.3% of what it normally is. That's about as good as Scotch Packaging Tape, which reduces it to 29.3%...

    Retrofit a 30" LCD, changing it from matte to glossy?

    I've been keeping a de-adhesived HEA2000K-clear sample and a MXA sample on my monitor for several days now (both with oil underneath), and I'm increasingly thinking that I don't want to settle for MXA. It's not nearly as anti-reflective as HEA2000K-clear; the difference is quite dramatic...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Some pictures of bottles of immersion oil might look brown just because the bottle is translucent brown. Edit: Also, even if the liquid is brown, it won't matter. You'll be using a very thin coating of it. Some of the oils I've experimented with are yellow or brown in large quantities, but on...

    Okay, some more findings (more favorable to the Photodon MXA than my first impressions): How Photodon MXA is better than HEA2000K-clear: * Photodon MXA film much easier to apply cleanly than HEA2000K. I'm having a very hard time getting the HEA2000K samples I currently have to adhere without...

    Retrofit a 30" LCD, changing it from matte to glossy?

    Well, I got my samples from Photodon. 4 days is pretty quick for free shipping! (The sample pack was $5.00.) So, I tried the "MXA Protective Film", which is the glossy version. It has front and back protective films you must remove first. But the adhesive is quite weak (which makes the film...
