Fastest Hard Disk Poll

[gianfranko]

I want to know who out there has the fastest hard disk. Please no RAID 0. I am talking about a single drive. Can you please include size (GB), RPM, seek time (ms), SCSI?

also please give me the output of hdparm -t
and if you have a SCSI drive please provide which controller.

[Spawn]

I don't know about the seek time or what you called it, but mine is a 45GB with something like 7400 RPM or so. It came with my Dell Pc.

[gianfranko]

what output does hdparm -t give you?

Did one little test. Pentium 166MMX. 32MB RAM. Slackware 7.1. Promise ATA/66 controller. Western Digital Expert 7200RPM 18.2GB drive w/2MB cache.

hdparm -t reports between 14MB to 15MB. That's using all the special tweaks from hdparm. Without those tweaks, I was getting around 11MB to 13MB.

Not to shabby, but I think I should be able to get a little bit faster data speed.... I dunno!

try going with an IBM drive. I have a 45GB 7200 RPM drive that really rocks. I'm away from my machine right now, but after work, I will try and remember to put up the results from hdparm. If I remember correctly, I was getting right arround 33MB per second (from disk, not cache) and was doing the benchmark in just under 2 seconds (Think it was right arround 1.9 seconds for the transfer). I will try to get official numbers for you later today...but you can't go wrong with IBM.

-plasmid

p.s. stay away from Western Digital...they have poor transfer times, and they tend to die in about 2.5 - 3 years

[bkurt]

I wouldn't go that far on the wester digital drives. They always get good reviews and have been known as one of the best drives for awhile now. Ibms are very good I won't doubt that, but western digitals are very good drives too. The last time I checked IBM actually made western digital drives. But I would have to give the speed race to IBM drives they do smoke.

I have my Linux install on a Maxtor 20Gb, 7200rpm, UDMA66 drive. My hdparm settings are -c1 -d1 -X66 -k1, and I get 114.29Mb/sec with hdparm -T.

now that is pretty fast for an IDE drive. How comes we didnt get any SCSI interfaces?

My HD is a Fujitsu 18.2GB 10000RPM and it runs kind of slow compared to the one mentioned above. I thought this was the case, and I wanted to confirm it.

sorry man, I thought there wasnt going to be a problem if I posted it here in General Linux Questions

[Shad]

Western Digital's use IBM platters, but contain thier own electronics. Rarely is there a problem with the platters, so the question is: do you trust WD to produce quality Electronics?

Anecdotal evidence: Everyone I have talked with that has had a HDD fail within the last five years, it has been a WD, myself included. The ones I can verify because of the nature of my tech support job, were likely Maxtors or WDs. Take it for what it is worth. My IBM 20.5gig 23mb Cache gets about 18mb/s, while the slave 30.5 gig Maxtor gets 13mb/s though it is stuck in PIO mode. These both reside on a UDMA/33 though it does use a UDMA/66 80 conductor cable.

[plasmid]

here are the results I promised from hdparm -t on my 45GB IBM 7200 RPM Drive

64 MB in 1.85 seconds = 34.59 MB/sec

Pretty fast huh?

-plasmid

[plasmid]

just in case you want to know, here are the buffer-cache speeds from hdparm -T

128 MB in 0.91 seconds = 140.66 MB/sec

like I said...IBM is the way to go.

-plsamid

[The King Ant]

These are the fastest out of 5 tries for each (-t and -T):

[root@diverge mark]# /sbin/hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 64 MB in 1.88 seconds = 34.04 MB/sec

[root@diverge mark]# /sbin/hdparm -T /dev/sda
/dev/sda:
Timing buffer-cache reads: 128 MB in 1.83 seconds = 69.95 MB/sec


The drive is an IBM 36GB Ultrastar 18LZX, Ultra160 HDD, 10,000RPM, 4.9 ms average seek, 4MB buffer (07N3200). It's SCSI.

The SCSI card is an Adaptec 29160, Ultra 160/LVD


And for an old Western Digital 3 gig, IDE, 5400rpm Caviar:

[root@diverge /root]# /sbin/hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 6.96 seconds = 9.20 MB/sec


[root@diverge /root]# /sbin/hdparm -T /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.85 seconds = 69.19 MB/sec

Neither drive is tweaked in any way. Kernel 2.4.0 It's strang that my buffer-cache times are the same for both drives...

[Xprotocol]

Gweedo mentioned Cheatas. From what I've heard these are some of the fastest HDs out there. I haven't tried one myself but I guess they really fly http://www.linuxnewbie.org/ubb/smile.gif. I know the RPM speed is 10,000 for most drives but I don't know anything about seek times or stuff like that. They're expensive but I would defenately check them out if you're considering a wicked fast HD.

IBM did manufacture a few Western Digital drives before. I believe the WD Expert line was made by IBM, completely. I have one of those drives, and a number of IBM drives. They are completely identical.

Also, I though hdparm only worked with EIDE drives?

hdparm edits a lot of settings for IDE drives, and I don't think there are any major settings for SCSI drives. But I guess it can benchmark both.

From the hdparm man page:
"Although this utility is intended primarily for use with (E)IDE hard disk devices, several of the options are also valid (and permitted) for use with SCSI hard disk devices and MFM/RLL hard disks with XT interfaces."

Maxtor 30gig 7200 ata100 on Promise Ultra100.

Plasmid is that an IBM GXP? I was about to get one of those when this Maxtor went on sale for $99. The IBM was going for ~$175 (local retail)

[Craig McPherson]

Bah... only 19MB/sec here.

I believe the IBM Deskstar series is the fastest IDE hard drive series around, in terms of overall performance. You can't get an IDE drive faster than 7200RPM, but the Deskstar has lower seek times and a larger cache than any of the other 7200RPM drives I've looked at.

For SCSI, I think the fastest are the Atlas 10K and the Seagate Cheetah series... last I knew. Correct me if I'm wrong.

[pipe]

Right on, Craig. That is the IBM Deskstar 75GXP (http://www.storagereview.com/map/lm.cgi/DTLA-307045).

[manual_overide]

I have a 45 gig IBM Deskstar 75GXP and a 20 gig Quantum Fireball KX. Both are 7200 rpm and are attached to a Promise ATA100 controller. The Quantum will only do ATA-66, but is still a fast drive. Although, it doesn't even compare to the IBM drive.

I can't give actual system times, because I am running Windows http://www.linuxnewbie.org/ubb/frown.gif and I don't know of a utility to check that.
