GRINDCORE MEGGIDO posted:If you mount it like that, does it report free space separately for the mounted path and the partition its "inside"? If you right click -> properties on the root drive ( eg C: ), you'll get the space free for only that drive, not any drives mounted to folders. If you right click -> properties on the mount folder ( eg C:\GAMES ), you'll get nothing, the graph will be empty. On that page will be a 'drive properties' button that will then give the free space for the mounted drive.

VostokProgram posted:If you have let an SSD get too full, will trim bring it back to normal performance when you remove some data? Do you need to secure erase the drive? It should. Some drives can take up to 24 powered on hours before they do their internal cleanup and actually prepare those blocks for future data, so just deleting a whole bunch won't make the drive instantly faster.

redeyes posted:loving ouch. That's a 100 fold reduction in price for that amount of nearline non-volatile storage with that kind of IOPS from just 10 years ago, and it fits in a single PCIe slot, not an entire 2U of space. It also looks like optane will have a bunch of additional capabilities. I expect the next server class chipset+xeon (C4000?) will have specific capabilities to take much better advantage of optane type devices (NVMe, DIMM, etc) that will be another step up again in performance and capabilities. This is really a first product to prepare the manufacturing and market, many more benefits are still to come.

Lum posted:Are there any M.2 2240 SSDs that don't completely suck. Are you sure that slot even offers PCIe lanes? Some laptop companies use the M.2 connector, but only hookup USB/PCM lanes, even though it's not spec compliant. It works for the modem / bluetooth cards, but nothing else. You may also never find an M.2 drive that has that keying, no matter the length. :/

Potato Salad posted:Manual trim doesn't wear the drive out, though. Good controllers (those recommended) just let data sit waiting to be overwritten. Sorry, but good controllers do not, in fact, do that. With spinning disk, a write operation and an overwrite operation take exactly the same amount of time. With solid state storage, a write operation and an overwrite operation take wildly different amounts of time, with overwrite being orders of magnitude slower. Long ago, when there was only spinning disk, file system developers realized they could save a lot of time if instead of going out and removing a file from disk when it was deleted, they could instead just mark that file as deleted in the file allocation table ( FAT ). Then, when a new file needed that space, the file system could destroy the old file and write the new file at the same moment, taking no extra time. ( undelete tools and data recovery tools rely on this ‘lazy delete’ approach when looking for data to recover. ). This type of file system in called a ‘lazy’ file system. Solid state storage needs to prepare a block to accept new data, and if it is not given time to do this, has to stop a write operation to prepare a block to be written, then complete the write. With a lazy file system, the storage controller on the drive itself had to maintain tables of allocated data and keep track of what was still valid, what was possibly not valid, and what it knew for sure wasn’t valid, and spend time cleaning up after the lazy file system ( garbage collection ). With a more modern filesystem, it’s possible to tell the drive exactly what blocks are part of a file that has been deleted ( TRIM command ), so they can be emptied and prepared for new data. The storage controller still waits until there is some idle time to do this, but it does so much more efficiently when it does occur.

Binary Badger posted:The only benefit to this is that the NAND is controlled by the T2 chip, so encryption is instantaneous and it accelerates most built-in SSD functions. Most SSD controllers do encryption for free, and there are a number of standards to let the operating system take advantage of that, eg: bitlocker can use the SSD controller for encryption. The major difference from Apple is that many controller makers are terrible at security and the encryption key can be trivially recovered if you have physical access to the device.

You guys are over complicating the patching issue. Because it’s hardware decompression, the data is likely compressed into discrete chunks of some size, and no chunk will have any need for another chunk during decompression. Any patch will just replace affected chunks with new ones, with it all determined during patch creation to be as efficient as possible. The compressed data can not be some giant winrar equivalent where there is a dictionary that gets built up so the decompressor must have access to earlier blocks to decode later blocks. Each chunk needs to be completely stand alone, so replacing chunks is easy.

Klyith posted:No PCIe version other than the first has made any difference to consumer uses at introduction. I'm guessing it's the datacenter people who are pushing for more PCIe bandwidth more than anyone else. PCIE4 will also help laptops/portables. PCB real estate is a huge premium in those, and being able to squeeze more out of less traces can make a noticeable improvement in performance and expandability. We are probably coming up on diminishing returns there, as PCIE5 will probably have tight EM requirements.

Bob Morales posted:Neither worked. If you did the migration using something like Macrium, check if the partition it created is set as active/bootable. I’ve had it sometimes just not do that.

Klyith posted:If they are very small 16-128mb partitions, they're a semi-useless thing that microsoft puts in for unexplained reasons on GPT drives. Possibly something for dynamic disks / storage spaces? I dunno. GPT secure boot requires partitions with a specific structure and contents to boot from, and these partitions are where windows ( and Linux ) put that media. If you are using bitlocker, this is also where the programs that can read TPM and automatically decrypt your drive live. Please do not delete them.
