similar to: SSD no longer detected - slightly off topic

I have a brand new 2T external Samsung SSD disk. (two of them) for backup. I tried the first one and had an issue, I tried the second one and got the same issue. Am I doing something wrong ? I find it hard to believe the SSD (both) are bad. I plugged in the USB 3.1 adapter, I fdisk /dev/sdd, n, p, default, default, w. then mkfs.ext4 -j /dev/sdd1, then just mount and rsync.

I grabbed a new SSD M4-CT064M4SSD2 from Crucial. I am disappointed. I stuck the unit in an Atom machine (zotac) with CentOS 6 on the disk. It really doesn't "feel" faster than the previous 5400 RPM drive that was in it. The SSD is giving me (in the zotac running centos 6): hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 298 MB in 3.00 seconds = 99.30 MB/sec The

https://bugzilla.samba.org/show_bug.cgi?id=13266 Bug ID: 13266 Summary: Writing of files to Apple's new "AP" controller model SSD's takes 4x longer. Product: rsync Version: 3.1.3 Hardware: x64 OS: Mac OS X Status: NEW Severity: critical Priority: P5

is that because the drive is compressing the information?? is there a way to turn this off?? i hate mandatory compression as losing one bit in a compressed file tends to be a big deal compared to the same in an uncompressed file. -- Securely sent with Tutanota.

Hi folks, For people who might be interested, here is how btrfs performs with two partitions on a single SSD drive in a RAID-1 mirror. This is on a Dell E4200 with Core 2 Duo U9300 (1.2GHz), 2GB RAM and a Samsung SSD (128GB Thin uSATA SSD). Version 1.03c ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block--

GigE wasn''t giving me the performance I had hoped for so I spring for some 10Gbe cards. So what am I doing wrong. My setup is a Dell 2950 without a raid controller, just a SAS6 card. The setup is as such : mirror rpool (boot) SAS 10K raidz SSD 467 GB on 3 Samsung 256 MLC SSD (220MB/s each) to create the raidz I did a simple zpool create raidz SSD c1xxxxx c1xxxxxx c1xxxxx. I have

Hello, I am setting up a new (remote) server. I initially installed 9.2 RC4 amd64 because that's what the data center put in the drive for me. Shortly thereafter I downloaded 9.2-STABLE sources and compiled world and a generic kernel. While doing so the system became unreachable by SSH The SSH sessions appeared to connect but there was never any data returned. I could telnet to port 22

Hi Yamaban, Great expalanation. I think you know how to buy an ssd. There is no doubt about samsung ssds quality vs other. My question about neutron was to get your opinion about this product. My doubt was about differences between slc, mlc and tlc. Mlc endurance respect tlc is better and I though that the mlc of neutron gives me more endurance respect to the tlc. From a technic point of view,

I just ordered a new machine that's destined to become a Centos 6 application server for a publishing company, and decided to get one with a 40GB SSD as well as a standard hard drive. I'm thinking that I can put most of the operating system on that drive and have the home directories and whatnot on the regular hard drive. Are there any pitfalls lying in wait for an unwary person like me

I have a C program on centos. When I call system("some_program &"); how do I get the PID of the some_program? I cant just list processes as there might be more than one some_program active. I need to know the one that I just started. Thanks, Jerry

You are probably looking for VMware Converter which can p2v or v2v. IMO: if you are creating a VM image which is a binary blob or image then you are doing it wrong. Have the VM/server/desktop be a simple next/next/next install and the

Hi, I'm having an issue with my Thinkpad P70 laptop/workstation. This system is a dual boot, windows 10 pro and centos 7. I have not needed to use the cdrom until now, however the system does not see it in /dev. I know the cdrom works as I can use it in windows 10 and when initially installing centos 7, I installed from dvd media. I'm not sure what to check. I do not see anything related

Hi All, What is the correct way to provide a CentOS 7 - WMware image for ESX ? As an amateur to VMware - I thought - great I can get VMplayer and ESX should be able to import my image... Wrong... I even went through the trouble of "converting" to VMWare workstation and thinking ESX could import that - Apparently still Wrong... I cannot for the life of me understand how one product

Hello, because of high disk load we plan to move from disk (raid1) to ssd. Are there recommendations for - manufacturer - file sytem - raid1 The Red Hat Storage Administration Guide says: - no raid 1 - ext4 only is this state of the art? I have searched list,centos.org 2015 - nothing found. I found in the year 2012 / 2013: https://www.centos.org/forums/viewtopic.php?t=7580
