HP and Hynix Semiconductor announced they've entered into a joint development agreement on a memristor technology called ReRAM claimed to be up to 100 times faster than flash memory while using one 10th the energy. ReRAM devices could start replacing random access memory (RAM) and flash within three years, and may eventually replace CPUs, too, say the companies....
Phase change memory (PCM) - an emerging non-volatile technology pioneered by Intel (NASDAQ: INTC), Numonyx, Samsung and others - could turn out to be a low-cost, more reliable, faster, and just plain better alternative to flash memorymore ...
Samsung has started mass producing 128GB flash memory chips that feature the highest density in the industry, and are made with a 10nm process. Such high-capacity flash memory chips already exist in the marketplace, and the South Korean company is looking to not only bring smaller flash memory chips to mobile devices, but also replace traditional hard drives.
IBM Research demonstrated what it claims is the world's smallest memory bit, using only 12 atoms. IBM's & atomic memory& prototype, by tapping the alternating magnetic spin of antiferromagnetic atoms, is said to achieve storage that is 100 times denser than today's hard disk drives and solid state memory chips....
It’s no surprise that as the processors for our Android devices get faster, other areas such as the device’s memory get faster as well. That’s why Sandisk has been working behind the scenes on its flash memory technology and recently announced it has begun customer sampling of flash memory products based on its 1Ynm process technology.
I am new to Mongodb and EC2. If I use following single MongoDb server :
High-Memory Extra Large Instance 17.1 GiB memory, 6.5 ECU (2 virtual cores with 3.25 EC2 Compute Units each), 420 GB of local instance storage, 64-bit platform
As a layman, if we quantify I/O, data in MB/sec.
I installed claire x86_64 version upon reading the news that 686 support would be dropped in the near future.Finding the memory usage to be exceptionally high, always hovering around 700-800mb with just firefox running (around 1-3 tabs open).
I am new at linux and currently I have a problem with my USB thumbdrive (can't access it either in windows - no volumes are shown).
cat /proc/scsi/scsi shows the following:
Host: scsi8 Channel: 00 Id: 00 Lun: 00
Vendor: Model: USB MEMORY BAR Rev: 1000
Type: Direct-Access ANSI SCSI revision: 00
dmesg shows the usb drive:
[ 1422.720016] usb 2-7: new high-sp
I have a Redis server running version 2.4.5 and with a dump.rdb of 11GB loaded into memory.
It is running on EC2 on a high memory 4x extra large instance (70GB total memory).
However, turns out Redis is already taking up 50GB of memory and is just growing more and more. My dataset is still gonna grow larger, probably to around 20GB, so clearly 70GB memory wont be enough.
