If you want something now, Hitachi is the best.
Right now I have 6x Hitachi 2TB and 6x Hitachi 3TB each in raidZ2 and they are great drives.
If you are asking about the best drive that will come out in 6 months, wait 6 months for an answer...
Also, it's worth noting that if a HW Raid 5 on an LSI 9260 will yield better performance or fewer problems I will go with that rather than RaidZ.
Thoughts?
I'm creating an array for ESXi storage and planning on using SSD's. I know they can be used for L2ARC and ZIL, but I'm wondering if anyone has experience using an all SSD array. I'm planning to run them off LSI 9211's (flashed with IT FW) and just wondering if there are any configuration issues...
AMT is separate from IPMI (AMT is consumer/workstation while IPMI is server based). Neither is supported on this system. Unless you need out of band management, I would opt for Xeon/ECC over Remote Management.
It needs 120hz input, which is different from a 120hz output. A lot of the non-3d tv's will display 120 or 240hz but they are still only taking a 60hz input and then doubling or quadrupling the frames. This will not work for 3d. It also needs to be able to sync to the glasses so that the...
I tried to flash my XFX 6950 and got a subsystemids mismatch in atiwinflash. Ran in an elevated CMD prompt and worked great, unlocked to 6970 and ran stable.
Performance is fantastic, everything runs very quickly.
The reason for the LSI 9260 would be that it supports the native stripe size for these SSD's. The 9240 that I am using only goes up to 64kb stripes and thus I am not getting optimal performance out of the drives. Hopefully I can pick up a...
I'm using an LSI 9240-4i with 4x Intel X25-E 32gb in Raid0. I have heard that I would get better performance switching to the LSI 9260 but I haven't tried that yet.
I agree that dollar to gig is much better on spindle drives now, but I really think we are going to see SSD dolar/gig marks...
I would buy now. The update is likely to remove the ability to flash to 6970 and they are switching from expensive VRM's to cheaper ones to save money. As a customer I would buy before they do this.
If you get the EARS drive download wdidle3 from here: http://support.wdc.com/product/download.asp?groupid=609&sid=113
then just load it on a bootable usb and run wdidle3 /s300 to set head parking time to 5 minutes. After that you should be all set, even if you decide to run the drive in linux...
Also the new EARS drives are 3 platter and should be faster and more reliable than the previous 4 platter design. For a backup drive you shouldn't have any issues.
EADS drives are 512b blocks and are fine for anything. EARS drives are 4k blocks and may need to have special steps taken if you use them in raid. Just using them in a dock you should be fine. What OS are you using them with? If you are using XP I would recommend the EADS drives to avoid...
Converted the array over to RAID-Z1 and got the following numbers. Similar write but much faster read:
freenas:~# dd if=/dev/zero of=/mnt/nas/zerofile.000 bs=1m count=10000
10000+0 records in
10000+0 records out
10485760000 bytes transferred in 58.469940 secs (179,335,912 bytes/sec)...
Ok, so I destroyed the partition and recreated checking use 4k blocks. It's still listing the partition as starting at 63 with 512k blocks but I'm getting 2-3x the speed:
freenas:~# dd if=/dev/zero of=/mnt/nas/zerofile.000 bs=1m count=10000
10000+0 records in
10000+0 records out
10485760000...
The Green drives are aligning 8 512k blocks to each 4k block, which offsets sectors starting at 63 causing the slow drive performance. By starting at 64 this is avoided, but I'm not sure how to do this with FreeBSD Raid formatted drives.
With linux I would:
fdisk - "sudo fdisk -u /dev/sda"...
The jumpers move the start sector from 63 to 64 which aligns the sectors on the 4k drives. This fixes the speed issues.
The difference in my situation is I am not using partitions on the individual drives so I theoretically should not have this issue. It still seems to me like this might be the...
I have FreeNAS 0.7.3 (5543) running on a Q9550 mini ITX system with 4GB of RAM. I previously had 3x WD20EARS drives attached and had good performance over gigabit ethernet. I just bought 3 more WD20EARS drives and destroyed the array to create a new one using graid5. All the drives are the...
This is exactly what I want in a laptop except I need USB 3.0. Very tired of netbooks and laptops that are not including it, and I can wait...
I'm about ready to give up and wait for lightpeak at this rate.
It seems like windows raid and hardware raid they are not so good without TLER.
For linux mdraid they are great. Also, the drives coming from newegg are the new style 3 platter designs with 666gb platters, so they are faster than the older wd20ears drives.
I have 4 of these already, but had to pick up 2 more at this price. Great drives, just make sure you set the head parking to something reasonable like 300/s.
I have tried a lot of options with my HTPC from linux to windows, etc... and the best solution I have found so far is Boxee.
It's free, I can stream music pictures and video off my network, it categorizes everything and adds cover art on its own, I can stream from websites, it works with...
We have caught a board on fire with as few as 4 enterprise class drives in RAID 0 running continuous IOPS testing here in the lab at Intel. With active cooling and depending on the board you may not have issues, but I wouldn't risk it.
If you run a bunch of SSD's in RAID 0 you will run into heat issues if your not using a discrete raid card. You can burn up your board with the throughput.
PCI-E SSD seems like the best option, but not sure about the compatibility. I'm sure it depends on the BIOS and OS.
Another alternative...
I have a FreeNAS (7.1.0) running with 3 WD Green EARS drives in RAID5. I switched over to these drives from 5 1tb drives (seagate and wd). I turned head parking to 300s (5min) and using raid5 have had no problem with the 4k blocks.
So heres the problem. My HTPC is attached over gigabit...
I had to jump on this deal. I have a Manfrotto ball head waiting for a deal on a tripod, and this was perfect.
Also according to Induro weight is 2.9lbs not 4.9 like amazon says (correct in description, just not details).
Is there a better solution for me using the WD20EARS drives? I am using them in FreeNAS and without going to an unstable build I don't believe there is 4k block support. I used the jumpers to fix the terrible speed problems people have without the jumper. I'm just using software raid5, not ZFS...
