Intel 540s worth it at $380

Intel usually has a pretty good reputation, but the 540 is so new at this point that we really don't know how it will stand up. Personally I'd aim for a slightly older design. MX200 1Tb maybe?

Why aren't there more ITX cases?

That segment is increasingly served by NUCs. DVD drives have been mostly phased out at this point. Most people don't need a second hard drive. Gamers usually want something bigger. So where does ITX really fit anymore?

What to expect for ATX 3.0 PSUs?

-12V has been gone for ages. A supply I bought in 2005 didn't have it. I'm pretty sure PCI didn't need it either. The only real "use" for it was RS-232 serial ports, and those have have had charge-pump-based MAX232's or similar available for the past 20 years. BJT TTL logic required bipolar...

Eliminating "CMOS" battery

Some of us work with computers in embedded applications, and its a lot of labour and troubleshooting, at an unwanted time. I can change the batteries with ease in my home computer. But what about a computer used for digital signage that's mounted 25 feet in the air? Or various applications in...

why is read and write so slow for 4k files?

Basically you can think of a SSD as being a filesystem which abstracts itself to the outside world as a block device. When doing many small I/O operations, there is considerable filesystem overhead involved with allocation, lock operations, etc. These scale up with random I/O to an extent...

Hard Drive that keeps going

Seagate 320gb PATA, ~70,000 hours Seagate 500gb PATA ~75,000 hours Hitachi 2TB 7k2000 ~57,000 hours I run everything in RAID-1, so basically I don't care how old drives get. They run until they die.

Broadwell-E 10 Core Costs $1723

And you are directly privy to the agreements under which such CPU's are provided to Intel's customers? You've seen the (probably highly confidential) agreement between HP and Intel? Unless you have, just what position are you really in to comment on this? I understand perfectly that some ES...

What brand of ssd to use or???

Practically any 240gb SSD will do just fine. On a machine that old, subtle performance differences aren't all that likely to even be noticed between the fastest SATA models, and slightly less fast ones. Crucial MX200, Samsung 850 Pro or Evo, etc., are some fairly popular models. For...

Eliminating "CMOS" battery

If the battery's not completely dead, it will indicate. If the battery is completely dead, bye-bye settings, and many boards won't even boot. This is the behavior I'd like to see changed, so that the UEFI firmware (or BIOS), through an option ROM, can contact a NTP server and set the date...

Eliminating "CMOS" battery

I was actually thinking along the lines of a manufacturing plant which may have a few hundred PC's scattered about for control, monitoring, surveillance, inspection, etc. PC's that, once installed, should run for many years without maintenance. If there's a power loss, 6 years down the...

Eliminating "CMOS" battery

Those could be made persistent in Flash, for example. Over-rideable back to defaults with jumpers. I have no issues with keeping the RTC, but why not make the battery optional? So those of us who don't want a RTC don't have to suffer having to perform maintenance on it?

Hi, Planning to buy used desktop computer, need a suggestion

A very capable machine. Only "gotcha" I can think of is that you won't be using 4K displays with the onboard video unless you use an additional video card. If you were to purchase the next generation, "Haswell", you would be able to attach 4K displays to the Intel embedded video.

Crucial MX300

This thread is making me glad I put in an order for some MX200's. The Samsung 840 / 840 Evo were fairly hyped drives straight out of the gate too, yet look at how they turned out in the real world. There's something to be said about being conservative with one's SSD choices. Especially if...

SSD vs HDD

I agree with your sentiment and you're mostly correct. However, lots and lots of people (even engineers) misinterpret what MTBF really means. MTBF is only valid over a manufacturer's specified "service life" (ie: 5 years for enterprise HDDs). MTBF is only valid over very large populations of...
