Do these SSD Speeds look right?

[Rocko1976]

Installed a Transcend 128gb SSD in my laptop. It's set to AHCI mode. Ran HDTune and the results are below. Do these numbers look right?

Dell Vostro 3500Laptop
Transcend SSD370(6Gb/s)

Thanks.

Looks about right. Not all SSD perform up to the quoted maximum speed. You can google the model and brand to see if other people are getting the same benchmark as you.

hi,

The drive isn't at it's full potential, but could be because you have a laptop

you should be closer to these speeds

SSD370: Read: 560MB/s, Write: 460MB/s
SSD340: Read: 550MB/s, Write: 330MB/s
SSD320: Read: 560MB/s, Write: 530MB/s

Looking at a review of the Vostro 3500, it has the HM57 chipset. Looking at that chipset online you are limited to SATA II speeds.

You should be able to see a lot closer to 300MBps. 275+ if you are using a SATA III drive. Check the SATA drive in another PC if possible, try updated drivers on the Dell.

Most of the SSD's speed comes from its random read/writes (anywhere from about 25 to hundreds of times faster than a HDD). So I wouldn't fret about the sequential read/write speeds being limited to SATA 2. That'll only matter on the few occasions where you're...

Well, since the Vostro 3500 doesn't have USB 3.0 ports and SATA 2 already exceeds gigabit ethernet speeds, it'll pretty much never matter. The drive can read/write faster than 125 MB/s (gigabit's max speed), but the only way it can transfer data to/from another device faster than 125 MB/s is via eSATA. So the SATA2 speed limitating will only matter if you you're reading from or writing to an eSATA SSD.

Ah, makes sense. Thanks.
