How Important Is Random Read / Write 4 Kb Speed ?

I've recently bought an ocz agility 120 gb and installed it in my laptop (hp hdx16t). I bought this one over the intel because it offered a better gb/$ ratio and i really wanted the extra space over the 80 gb intel (and the 160 gb intel was out of the question due to price). After a fresh win7 64 bit install, the performance was truly great with some things and not as great as i was expecting with others. Not all things (like firefox, for example) immediately snapped up. So i downloaded and ran crystaldiskmark and checked the data rates. They appear to be not quite as good as they appear in the anandtech recent intel x-25m g2 review. Speed was good for sequential read/write and random read/write 512kb was good too, but random 4kb read/write was about 14mb/sec and 7. 5 mb/sec, respectively. I understand these scores are much better than a hdd, but according to reviews the intel's are getting closer to 50mb/sec read, 35mb/sec write for the random 4kb test. So my question is - how important is the 4kb random test? There are actually some areas where the ocz beats the intel (like sequential write and 512kb random write), so if these areas are just as important, maybe its worth keeping the drive. Should i keep the ocz and just be happy with it, or return it in favor of the smaller drive even though it would make data storage a little uncomfortable?

Any thoughts?

Recommended Read / Write Drives

I was hoping that the forum members could offer some recommendations as to a read/write disk drive. You know for installing software and saving date and on read and writeable disks. I would like one that can do reading, writing, reproducing (burning) etc. I would like a brand that the forum members think is reliable and handles all the different media types that disks come in.

Display Memory Read / Write Failure - Pc Gives 8 Beeps After Power On

I just installed an athlon 64 system. I kept getting 8 beeps right after i turned the power on and once in a while. According to by motherboard manual it means "display memory read/write failure" i never had this problem before with my old athlon xp system. What's wrong here?

Computer specifications:

Athlon 64 3200+
512 mb ram(had to take out 2 slices because the mb doesn't support 3 slices of ram)

Cdrw - Read / Write Error Or Bad Medium Detected

A friend of mine bought my old hp 7200i 2x2x6 cdrw off me and is getting a burn error with nero and goldenhawk. The error seems to be the same and the drive acts fine otherwise. It worked great and nothing has been changed [ide wise]. Error: write command failed on device 1:1:0
Read/write error or bad medium detected 04h 00h 02h 03h 73h 02h

It happens right at the beginning of the burn-process, just after the lead-in is written.

Usb Drive Disappearing / Reappearing On Write

Recently purchased a hdd dock, the type where you push the bare drive into the top. Everything appears normal after inserting a disk until i try to write to the drive. When i try this the drive will disappear from 'my computer' and an error message appears informing me the disk is not available and a moment later the auto-play prompt will appear informing me the drive has been added. It's worth noting however a few small mp3's managed to copy over fine. What i've tried

1. Tried different hdd's
2. Different usb port and different usb cable
3. Tested on another computer
4. Changed the drive settings i.e. Write caching on/off

Usb Key ( Flash Drive ) - No Write Access

I've bought an expensive usb key ( flash drive ) and i've been successfully using it for a month or two. Suddenly i can no longer write to it (tried several computers). I can still read from it, so is this a physical problem or something to do with the file system (i should mention that i don't exactly take care of it, it doesn't have its cap etc. )?

Drive Benchmark Tool Issue

So i jumped on the dell 2x 1. 5tb seagate deal. The drives came in today and i decided to thrown them on raid 0. Out of curiosity, i wanted to benchmark them vs the 2x 74gb raptors i use as my system drive. Not being familiar with hdd benchmarking i grabbed crystal disk mark. The numbers i got back shocked me. Seagate 1. 5tb 7200. 11 in raid 0

Sequential read : 254. 385 mb/s
Sequential write : 251. 397 mb/s
Random read 512kb : 49. 769 mb/s
Random write 512kb : 105. 393 mb/s
Random read 4kb : 0. 661 mb/s
Random write 4kb : 2. 947 mb/s

Wd raptor 74gb in raid 0

Sequential read : 116. 132 mb/s
Sequential write : 111. 143 mb/s
Random read 512kb : 38. 293 mb/s
Random write 512kb : 67. 147 mb/s
Random read 4kb : 0. 665 mb/s
Random write 4kb : 2. 562 mb/s

Is this benchmarks tool just plain wrong? Or are the raptor so old that the tighter platters on the 1. 5tb drives simple out-pace them?

Usb Flash Drive Speed Is Very Slow

I need a larger usb flash drive and was wondering what people would suggest. I have a 4gb drive now, but need something bigger. I have noticed that the transfer rate to my drive is very slow and was wondering if that has to do with the usb technology or because of my drive. I'd like one that transfers as fast as possible, but if they all transfer at the same speed, then so be it.

Usb Message: Hi-speed Device Plugged Into A Not Hi-speed Port

I'm rebuilding my system, and have two pci cards with firewire and usb ports. I remember before the rebuild i plugged them in and they worked. That was nice. Now, i installed them one at a time. The first one prompted no notifications, but when i plugged a device into it it warned me that it was a hi-speed device plugged into a not hi-speed port. I installed the second one, and it prompted the new hardware wizard, asking for drivers, but said it couldn't find them although i had dsl connected. The cards did not come with any disks and there was no problem getting them to work before.

Usb Works With Keyboard And Mouse But Won't Read Usb Stick

Hello guys, i've this problem since some time. My keyboard and mouse work properly but the system seems to fail in reading usb sticks. They do appear in my computer but when i access them it either says " f: is not accessible. Impossible to satisfy your demand because of peripheral error e/s ", or, it allows me to enter it but there are no files listed. The stick works ok in other machines and there are files on it. It also takes a long time for the system to see the stick. I did have some viruses but now the comp is clean as i ran all the programs suggested in networking&security section of this forum. Help!

Usb 2.0 External Hdd Error Windows Delayed Write Failed

I purchased a western digital 40 gb, 5400rpm usb2. 0 external hdd(2. 5") recently and when i try to copy large cunk of data, windows gives me an error

"Windows-delayed write failed"
Windows was unable to save all the data for the file deviceharddiskvolume6. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file else where. But small chunks of data can be saved. Also when this happens, windows does not recognize the partitions of the usb drive and shows only one letter for the drive without any contents!

My pc's configuration is as follows:

850mhz celeron
256mb sdram
Internal 20gb samsung hdd(54000rpm)
Pci-to-usb - pci card fitted into pci slot(has 4 usb outlets)
Windows 2000 professional with sp4

I have no conflicts whatsoever with the usb drivers. One more thing; i have not faced the above problem when i try to transfer data from another system which is of a higher configuration than what i have mentioned above. This system's configuration is:
Windows 2000 professional service pack 4 (build 2195)
1. 93 gigahertz intel pentium 4
8 kilobyte primary memory cache
256 kilobyte secondary memory cache
512mb ddr-ram

Any fix?

Dell I9200 Laptop Usb Ports Are All Normal Speed Not Usb 2.0

I purchased a refurbished dell ( inspiron ) i9200 laptop a few months ago, haven't used any 2. 0 devices until last week, when i plug it in it says my ports are all normal speed, however i know they're supposed to be 2. 0.

Seagate Drive Failed - System Unable To Read From The Drive

The drive in question is a seagate barracuda 7200. 11 500 gb, with original firmware being sd15. As i've got to know of their "built-in failure", i've immediately flashed the firmware to the current available sd1a. I thought it will prevent from the drive failing. Now a few days ago i was happily using my computer without a hitch. At one moment os was unable to read from the drive and rendered it unusable (the gui at least), and the mouse cursor freezes for a few seconds in one second delays. This behaviour stopped immediately as i disconnect the drive from the motherboard.could that have been caused by me hot plugging the drive a few times? Or is it the drive itself and nothing can be done now? The system will boot with the drive connected but it will take very long. I've got maximus formula motherboard and two 500 gb's in raid0 for os partition. One wd 500 gb, one seagate 1tb, and the drive in question.

Ps3 Wont Read Ntfs Usb Drives

Why is it the ps3 can't browse large usb drives formated in ntfs? When the lg, samgsung and even sony(i think) network blu-ray devices can with no problem? If i could find a network blu-ray dvd player that could navigate my windows shares and play avi or wmv files i'd return the ps3 right now.

Usb Transfer Files Won't Read

Everytime i transfer files to my usb like ms word document, pictures, and music. The file won't read! Why is this happening? For instance, if i try to open the picture i saved, all i got is a "mini x" and if i try to play music it won't play either. Next, i created folders with some documents inside it. If i try to open that folder, there is no file displayed. At first, i thought it was a bunch of hidden files. So i tried to change the settings to make invisible files visible. No luck. My files are nowhere to be found! If i try to delete it, i got an error message " cannot delete file. "

Note: i did error checking and also tried reformatting it. Unfortunately, its still not working. It still has a problem with reading/opening files. Worse, some of my files are freaking' hidden( despite making invisible folders visible)

Some additional info about the usb i'm using. 1gb kingston
Type:removable disk
Filesystem: fat32

Backup: Can Not Write To Disk, Disk Write Error

I was saving the backup file in quickbooks & have done this thousands of times. During the backup it said can not write to disk, disk write error. Than the error started popping up for tons of folders on the same drive. This drive is my secondary drive, not the main drive. So i restarted my computer. & Chkdsk ran so i let it do its thing. It got to step 3 & said insufficient disk space to fix the bad clusters file. Chkdsk aborted. Which did not make any sense because this drive has over 200gb open. So now the computer is running ridiculously slow & my f & g drives (same hard drive partitioned) is now not being recognized. So i tried to run chkdsk on those drives & it said the drives are raw. The drive can not be raw because it has over 250 gb of files on it. So did my hard drive crash? I have had a crash in the past, but this seems different. When i go to my computer i see local disk f & g but that is not the names they used to be called & the drives dont open if clicked on them. Luckily i have everything backed up pretty regularly on 2 other drives. However it has not been backed up for a week or two so that part sucks. Does anyone have any ideas?

Mentor Usb 2.0 Pcmcia - Pioneer Dvr-108 Read Cds Very Slow

I have a laptop running windows xp w/sp2. I have just got a mentor pcmcia 2. 0 usb pcmcia and a usb enclosure for a pioneer 108 dvd-rw. At one point the dvd-rw was picked up and i could read the cds but it was very very slow, even to respond. Now the card does not show the drive up at all and its starting to cause the system to drag. What could be the cause for the problem?

The card has no drivers, its supose to just work right out of the box. Can anyone offer any suggestons? At one point it was locking the system up. From what i can tell this card has a o2micro chipset, could that be defective?

Floppy Drive Does Not Read

http://www.Newegg.com/app/viewproductdesc.asp?Description=21-103-116&depa=0

Thats the floppy drive i isntalled, however i am having some problems running it. The computer recognizes it, however when i insert a floppy it doesnt read it, says please insert floppy as if there was no floppy in there, but there is. Ive tried it with 10 different floppys they all had the same message. Tried them in my other two pc's and they work fine. Any ideas as to what my problem is?

The light on my floppy drive is also always on, shouldn't it be off when not in use? Maybe i installed incorrectly.

Read External Drive

My sister has run into a problem. She had a trojean or virus on her computer. She took it to the campus tech lab or whatever. They just replaced her drive and charged her 250. It sounds to me like they did nothing to the other drive at all. Now, she needs her files (on her old drive) for school. Is there some way of reading an external laptop drive and retrieving the files? Looking for an option that doesnt require the dishing out of major bucks.

Read Old Boot Drive

I just built a new xp machine, the mobo is an asus p5b, 2 gig ram, 7900gt vid card, e6600 cpu. Teac cd, hard drive is a w d sata. Everything works as it should. The mobo will also accept to ide drives. The cd is connected to the ide as cs. Now the problem: i have 2 ide hard drives from the previous machine, one which it booted from (ntfs) and a larger drive for data (fat32). I can install the data drive in the new machine and it works. When i try to install the old boot disk the machine will try to boot, the correct lights go on and it sounds like it is going to work, but then the activity light on the old boot disc starts flashing, and after a few seconds it will flash in sync with the lights from the sata drive(which is where it should be booting from). It does not boot and i have to turn the ps off to stop it. I removed the cd and i have tried setting the old boot disc to slave, master, cable select, and something called pts?, None of which changes anything. The bios boot screen shows the old boot disc correctly so it is happy with it, i would assume it is xp that is causing the problem. I have the boot listing in the bios set so that all are disabled except the sata drive. Does any one know how to get it to not try and boot from the old disc.
