Hard drive performance

Code:

root@fireball / # hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   6902 MB in  2.00 seconds = 3452.53 MB/sec
 Timing buffered disk reads: 328 MB in  3.01 seconds = 108.81 MB/sec
root@fireball / # hdparm -tT /dev/sdb

/dev/sdb:
 Timing cached reads:   6894 MB in  2.00 seconds = 3448.87 MB/sec
 Timing buffered disk reads: 328 MB in  3.01 seconds = 108.86 MB/sec
root@fireball / # hdparm -tT /dev/sdc

/dev/sdc:
 Timing cached reads:   6568 MB in  2.00 seconds = 3285.27 MB/sec
 Timing buffered disk reads: 332 MB in  3.01 seconds = 110.16 MB/sec
root@fireball / # hdparm -tT /dev/sdd

/dev/sdd:
 Timing cached reads:   7096 MB in  2.00 seconds = 3549.96 MB/sec
 Timing buffered disk reads: 488 MB in  3.01 seconds = 162.33 MB/sec
root@fireball / #

I need to do some upgrading, AGAIN.

Code:

hdparm -tT /dev/sda
/dev/sda:
 Timing cached reads:   12406 MB in  1.99 seconds = 6221.26 MB/sec
 Timing buffered disk reads: 516 MB in  3.01 seconds = 171.48 MB/sec

It's a Kingston SS100S216G 15GB SSD in a Toshiba Satellite A665-S6092.

Mine's just a plain old SATA drive. I may get me one of those SSD thingys one of these days tho. The price is coming down now.

I got only 15gb SSD because it was SO much cheaper than larger capacity drives. I just use an external drive for saving things like pictures, etc. I highly recommend Kingston, mine has not slowed down or exhibited any unusual behaviour for 28 months. If you want the low price shop Newegg. If you are talking about getting one for a laptop look at this URL:

It has a Kingston 60gb SSD for $69.99.

My rig is the one in my sig below. I plan to upgrade the mobo, CPU and ram sometime soon. I'm just waiting on that sweet spot with prices.

As a Linux user, I would have /home and /var and such on a regular drive but have /, /usr and such on a SSD. They would prevent the frequent writes and such that wear them out. Plus, my case stays really cool so it wouldn't ever get hot or anything.

I suggest getting an adapter from 2.5" to 3.5" so a 2.5" can be secured properly in your PC. The 3.5" SSDs are uber expensive. Newegg has these adapters.

I'll either buy one or make one. I'm quite handy with metal, wood and such.

I've done quite a bit of fabricating myself over the years. That said here's one:

Not that expensive and saves a lot of work making one. It can accommodate two 2.5" drives. And if you order the hard drive you'll save on shipping, they will throw it in the same box.

And you look at the first results posted for hdparm and this is the speed:

The last one is an IBM 20G Deskstar.

Right now, about every system that is fairly current is well over 100Mbs/sec. Isn't it amazing how much faster systems have gotten since this thread started?

Indeed !!
