The General Technology Thread

[BugI02]

My MBP has a SSD. And I guess I’m kinda used to that. I’m wondering about the benefits of a hybrid. Because it seems like with SSHD, the SSD part is just acting like a big ass cache on a HDD. The idea is to get the cheap storage of HDD, with the speed of a SSD. I’d like to know if it’s really all that.

I've got the 2TB fusion drive on my desktop. 128GB SSD. It noticeably speeds up a lot of everyday operations (esp. boot) and responsiveness

Four of these are SSD, two HDD. Couple more SSD in, just not online at the moment.

Usually use them for games with big, open worlds. Helps a ton with loading and performance on those.

Probably three different SSD qualities here, too. The NVME connects directly to a PCIe bus on the motherboard, very high performance.

C: is just a very fast SSD, gives about 4-second boot-up.

I really need to finish and uninstall some games...

SSHD vs HDD, or SSD vs HDD?

If the latter, yes.

I don't have enough experience with SSHD to answer that, though.

Ive got experience with them.

They were a great crutch before the monopoly/price fixing was busted around a year ago. Now SSDs are down in price that you dont need a SSHD unless its in the >2TB range.

Basically its a spinning platter disk, which are cheaper to produce in larger sizes and last longer, but slower. It also contains a special solid state HDD at a fraction of the size but big enough to hold the OS and the most frequently used files. The drive would figure out what was used most and keep those files in flash, and stuff like your MP3, movie, and photo collection on the slower platter where it didnt really matter how fast it was accessed.

If you are considering moving to SSD, buy twice the space you need. There needs to be plenty of room to move data around the physical chips to do what is called wear leveling. Got a nearly full 250g drive? buy a 512 or 1TB SSD drive when you replace it. Here's why:

Unlike platter based drives, the individual sectors on a SSD have a much lower life. After flipping the switch on and off so many times as it writes data, it eventually wears out and has to be avoided. Eventually you run out of good sectors. (still a long life)

Think of it like a sheet of graph paper. You are constantly coloring in squares and erasing them. After erasing a square so many times, eventually your eraser goes all the way through the paper and makes that square unusable. Using a process called wear leveling, the WHOLE drive is used and files are physically moved all around the drive to wear down the sectors equally, and much more slowly. So imagine not always erasing the same squares over and over, but moving around the entire page to make sure you dont burn through a square.

But what if you have the drive nearly filled with static content like home movies and photos? Now imagine that same paper, but 2/3 of the sheet is colored in and never touched. Since you have much fewer squares to choose from, you are going to wear out whats left of the paper much sooner. You end up overworking that small section of the paper (drive) and it eventually wears out.

SSDs are awesome.

Thanks. It does sound like the sshd's use flash as sort of a big ass cache, but more permanent than a cache. My work MBP only has 256GB SSD. I like the speed, but I do wish it were bigger.

Whelp.

Mine died a while ago, might just leave it dead.

Indiana House OKs legislation barring companies from microchipping their employees

I'll just wait here for complaints about government intervention, pointless laws, laws preventing free capitalism, and "if you don't like it don't work there."







And I'll wait for the GA to do something about actual invasion of privacy happening right now, e.g. Ring, cellphone tracking, facial recognition.

But what if someone finds a stray employee wandering around with no collar or tags? The microchip would make it easier to return them to their rightful employer.

I think in a different time, the revelation about Ring would have bankrupted them. I know so many, albeit, Millennials, who think it's just fine if everything about them is made public knowledge as long as they get free **** or cool gadgets.

This measure has been introduced during the last few sessions. This is the first time it has actually gotten any traction.

In Cincinnati today, might have to stop by Microcenter and pick up some PC parts that are on sale... considering the Ryzen 7 3800x

Even though this was sparked by my fear that RDR2 wouldn't run well on my current PC (it runs amazingly...), it's like buying guns. Sometimes you just have to do it.

My son lives very close to that Microcenter. Every time I go visit him I'm tempted to stop in. Haven't had a Microcenter near me since I lived in Minnesota. Fortunately thus far I've avoided temptation because I know if I visit I'll leave poorer by a lot...

Does one really need that level of **speed** for the mundane things they do: email, office software, porn watching.

Is it really all that more performant than HDD with a big ass cache and good memory management?

Need, of course not, just wait for everything to load and don't ever use a machine with an SSD.

Long ago before SSD was a business class staple I tried a laptop with a hybrid drive (spinning disk with some SSD cache). When I finally got the SSD there was no contest. They attempt to use algorithms to figure out what files are accessed the most and keep them on the flash memory but in reality they fail miserably because the flash memory is tiny, usually 8 - 16GB. At minimum you want your OS to run entirely from the SSD, it performs thousands of IO operations any time you do something and that is where the primary performance boost comes from.

The big transfer speed numbers advertised for SSDs are mostly pointless to an every day user. IOPS on the other hand is where its at. Just about any SSD will totally destroy a spinning disk in this category.

Did it.

Went with the 3700x instead of the 3800x... the differences were negligible.

Asus TUF Gaming x570 mobo, and 16gb Corsair DDR4-3200

Should be a fun weekend.

Okay, I have to admit that I thought you were trying to run R2D2 on your computer and thought, "What?"
