                        SEVERANCE AND RELEASE AGREEMENT

       This Severance and Release Agreement (the "Agreement") by and between MTI
Technology Corporation ("MTI" or "the Company") and Daniel Brown ("Brown")
documents the terms and conditions of Brown's termination from the Company,
effective September 22, 2000.

                                    RECITALS

              On or about September 28, 1998, Brown commenced employment with
MTI, and is presently in the position of Senior Vice President of Product
Development and Support.

              On or about September 20, 2000, MTI and Brown mutually agreed to
terminate Brown's employment, effective September 22, 2000. MTI does not have a
uniform policy or practice of granting particular severance benefits to its
employees or executives. However, MTI offered to pay to Brown only those
severance benefits described in the paragraphs that follow in exchange for
Brown's release of all claims against the Company. Brown accepted this offer.

                                    AGREEMENT

              NOW, THEREFORE, in consideration of the recitals listed above, and
the mutual promises contained in this Agreement, Brown and the Company agree,
covenant, and represent as follows:

       1. SEVERANCE PAYMENT.

              After the Effective Date of this Agreement, Brown shall receive a
severance payment from the Company in the total gross amount of $132,500.00 (the
"Severance Payment"), to be paid bi-weekly in thirteen equal payments of
$10,192.31 ("Installment Payments") beginning on MTI's first payroll date
following the Effective Date of this Agreement. Brown understands and agrees
that MTI will deduct from the Installment Payments all applicable taxes, social
security and other standard authorized amounts. Brown acknowledges that, but for
entering into this Agreement, he would not be entitled to a Severance Payment in
this amount.

       2. TERMINATION OF EMPLOYMENT.

              a. Brown and the Company agree, covenant and represent that
Brown's employment relationship with the Company shall terminate effective
September 22, 2000 (the "Termination Date"). As of the Termination Date, MTI
shall pay to Brown (i) all accrued but unpaid salary as the Termination Date in
the total gross amount of $5,096.16 and (ii) all unused vacation pay accrued up
to and including September 22, 2000 in the amount of $20,601.21 (collectively,
the "Termination Payment"). The total gross amount


                                       1
<PAGE>   2

of the Termination Payment is $25,697.37. MTI shall withhold from the
Termination Payment all applicable payroll taxes, including federal and state
income taxes, as well as other authorized deductions.

              b. As of the Termination Date, MTI and Brown agree that Brown
shall be retained by MTI as a consultant pursuant to the terms and conditions of
the Consulting Agreement attached as Exhibit "A" (the "Consulting Agreement").

              c. Brown acknowledges that, as of October 1, 2000, he may be
eligible to obtain continuing coverage under MTI's group medical, vision,
dental, and life insurance plans pursuant to the provisions of the Consolidated
Omnibus Reconciliation Act and its implementing regulations ("COBRA"). Brown
will receive under separate cover all required documentation and election forms
so that Consultant obtains continued group health insurance coverage pursuant to
COBRA. MTI acknowledges and agrees that, from October 1, 2000 until April 30,
2001, MTI will pay the premium payment for any COBRA continuation coverage that
Brown elects to obtain. MTI further acknowledges and agrees that, from October
1, 2000 to April 30, 2001, MTI will reimburse Brown for medical, vision, and
dental expenses incurred by Brown that are not covered by Brown's COBRA
continuation coverage but that would be covered under MTI's existent Executive
Medical Plan. In no event shall MTI be liable for, or required to pay premiums
for any COBRA continuation coverage or other medical coverage that Brown may
elect or be eligible to obtain after April 30, 2001.

              d. Subject to the approval of MTI's Board of Directors'
Compensation Committee, MTI agrees that Brown's Option Agreements shall remain
in full force and effect during the term of the Consulting Agreement. Brown
understands and agrees that his right to exercise these shares shall be in
accordance with the terms and conditions his Option Agreements with the MTI and
the MTI Technology Corporation 1996 Stock Incentive Plan, as amended (the "Stock
Incentive Plan").

              e. Brown and MTI agree, covenant and represent that Brown shall
not be eligible for, or entitled to, any benefits of employment other than those
specifically identified in this Agreement.

              f. Brown agrees, covenants and represents that he shall cooperate
with MTI in the orderly transfer of his responsibilities to other MTI employees.
Brown further agrees, covenants and represents that he shall cooperate in good
faith with MTI in the defense of any action that has been or will be brought
against MTI that arises out of, or relates in any way to his employment with
MTI.

       3. RELEASE.

              a. In exchange for the Settlement Payment in the total gross
